Faculty Profiles 8th MTN Workshop

Abstract:
For this 8th Muscletech Network Workshop, I have been asked to show a proposal for rehabilitating Rectus Femoris
Injuries, within the Treatment and Rehabilitation block of the program.
Scientific evidence provides information regarding biological repair processes; fusiform and biarticular anatomical
features of this muscle (Mariluis et al. 2015) and its high percentage of type II fibers (Johnson et al. 1973) typical of
those muscles who have to perform actions that require large changes in length at high speeds (Mendiguchía et al.
2013); its functions in regards to knee extension, hip flexion and stabilizing the pelvis in monopodales supports (Shu and
Safran 2011; Bordalo-Rodriguez and Rosenberg, 2005); injury mechanisms, among the actions that occur during
accelerations, decelerations and kicking the ball (Mendiguchía et al. 2013.); the modifiable risk factors, among which
include: length/tension relationship, core stability (Mendiguchía et al. 2013; Witvrouw, et al. 2003; Bradley and Portas,
2007; Fousekis et al. 2011), weakness and shortening of the iliopsoas (Sanmarco and Stephens, 1991; Sahrmann, 2002;
Lewis and Sharmann, 2007); inadequate eccentric strength of the rectus femoris especially in relation to the dominant
knee with hip involvement (Mendiguchia et al. 2013.); along with other risk factors (Konstantinos et al. 2010).
Similarly, scientific evidence also provides us with the most adjusted measures to address these factors, the moments
and steps to develop a proposal for rehabilitation and the characteristics of the exercises (Pincivero et al. 2000;
Thorborg et al. 2015; Jansen et al. 2012; Mendiguchia et al. 2013).
Therefore my intention for this talk is to show a practical proposal of a rehabilitation program based on this efficacy
given by scientific evidence, and transfer this evidence into practice using as support the creative capacity and
adaptation to the work context (Cos et al. 2010; Finch, 2006; Hanson et al. 2015).

Title:
Rehabilitation of rectus femoris injuries. Experience at Sevilla FC

Abstract:
Varying injury characteristics have been suggested to potentially influence the time to return to play for athletes with
acute rectus femoris muscle injuries. The current evidence however is very limited, and as perceptions of certain critical
elements evolve, these might influence the treatment, as well as the decision on readiness to return to play. In order to
minimize bias of the initial expectations on elements related to prognosis, a standardized criteria-based progression
protocol is necessary. In this presentation, the development of such protocol will be discussed along with our
experiences using this protocol in a larger prospective study. Included in this will be a structural division of elements
considered in the rehabilitation program, and a discussion on optimal loading after injury, including elements such as
exercise selection, intensity, pain acceptance, and criteria to return to play.

Title:
MRI anatomy of the quadriceps

Abstract:
High-resolution ultrasound (US) is able to provide a comprehensive evaluation of the complex anatomic architecture of
the quadriceps femoris. In the rectus femoris muscle (RF), US can provide accurate depiction of the origin of the direct
tendon (DT) from the AIIS and of the indirect tendon (IT) from the groove above the lateral acetabulum. In distal
continuity with its proximal tendon origins, the RF shows a complex internal structure that influences type and location
of its tears. It consists of a “muscle-within-muscle” structure made up of a smaller inner belly (IM) enveloped by a larger
outer belly (OM). The OM arises from a flat coronal-oriented superficial aponeurosis that derives from the DT. Muscle
fibers arising from the lower aspect of this aponeurosis travel deep and distally to reach the deep distal aponeurosis
which continues in the superficial layer of the quadriceps tendon (QT). The orientation of the muscle fibers gives a
unipennate appearance to the OM. The IM originates from the central aponeurosis, a thin sagittal-oriented fibrous band
which derives from the IT and is located within the cranial two-thirds of the muscle belly. Muscle fibers from the
external and internal surface of the central aponeurosis run distally to insert into the deep distal aponeurosis, together
with the OM fibers. Therefore, the US appearance of the RFM is that of a small inner bipennate muscle surrounded by a
large unipennate muscle. The vastus medialis (VM) and lateralis (VL) muscles originate from the linea aspera and insert
distally into the middle layer of the QT. The proximal tendon of the VL is located in close relationship with the distal
insertion of the gluteus minimus and some fibers can be seen blending among these tendons. With respect to the RF,
some distal fibers of the vastus medialis and lateralis can be seen extending away from the midline to insert into the
patellar retinacula and reach, for the VL, the iliotibial band. The vastus intermedius is the deepest of the four muscle
bellies and is located in the midline deep to the RF and superficial to the femoral shaft, between the VM and the VL. It
arises more distally than the VL and can be seen inserting into the deep layer of the QT.

Abstract:
Muscle injuries have a tremendous impact in sports due to time lost in competition and decrease in performance. The
risk of re-injury in muscle injuries is not low, making it really a big issue for athletes, coaches, athletic trainers, physical
therapists, and physicians. The best management strategy for muscle injuries is its actual prevention. To accomplish this
goal, an adequate and deep understanding of the risk factors for injury is crucial. The purpose of this communication is
to provide an up-to-date review of the literature regarding risk factors for rectus femoris muscle injuries in sports.

Title:
Risk factors for rectus femoris muscle injuries

Abstract:
Quadriceps muscle strains frequently occur in sports that require repetitive kicking and sprinting efforts and are
common in football in its different forms around the world. The rectus femoris is the most commonly injured muscle of
the quadriceps muscle group. According to Ekstrand et al 17% of the lower limb muscle injuries are to the rectus femoris
In our hospital we have a unique project: the National Sports Medicine Program wherein we provide sports medicine
service to all clubs and federations for all registered athletes in the country. The Qatar football federation contains
approximately 420 professional players and around 4500 amateurs. Each of these athletes has their medical care
administered by a member of our team, and the results of any medical encounters are available for review. In a 5-year
cohort (2010-2014) we found 17% of the overall lower limb muscle injuries to be rectus femoris injuries, matching the
incidence documented by Ekstrand et al (2) which suggests similar mechanisms and burdens are present in this cohort
as to the one documented by Ekstrand et al.
The football players of the Qatar Stars League annually perform a pre-season physical screening which includes
isokinetic testing of the knee flexors and extensors, at 60°/sec concentric, and 300°/sec concentric, as well as eccentric
testing of the knee flexors at 60°/sec. Data will be presented on the utility of such testing in identifying players at risk of
injury to their rectus femoris muscle in the subsequent season. These data may inform risk identification and injury
prevention strategies in other professional football players.

Title:
Epidemiology of Rectus Femoris at Aspetar

Abstract:
Injuries to the Quadriceps Muscle Complex (QMC) forms a considerable part of athletic injuries and is therefore
frequently seen in clinical and imaging sports medicine clinics. The MR imaging anatomy of the QMC is pertinent to
understanding injury patterns, as well as severity and will be reviewed. MR imaging is particularly useful in the elite
athlete due to its high sensitivity to localise and characterise injuries, as well as having the ability to prognosticate,
thereby ensuring optimal patient outcome by assisting clinical colleagues in tailoring treatment regimens specific to the
injury sustained.

Title:
MR Imaging of the Quadriceps Muscle Complex (QMC).

Abstract:
Quadriceps muscle is situated in the anterior side of the thigh. It is formed by four muscles, rectus femoris muscle
vastus medialis, vastus intermedius and vastus lateralis with different origin each one. Nevertheless, this last year it has
been described a new muscle, the tensor of vastus intermedius muscle between the vastus lateralis and the vastus
intermedius. They join in the inferior part of the thigh in the quadriceps tendon when they arrive to the patella. Several
descriptions have been demarcated about the quadriceps tendon. It is formed by laminas although there were distinct
lamination patterns bilaminar, trilaminar even four-layered that comes from the different parts of the muscle, and also
with different patterns. Finally the tendon follows until achieve the anterior tuberosity of the tibia bone as quadriceps
ligamentous. It is the extensor of the knee. And it is innervated by the femoral nerve a nerve off the lumbar plexus.
Of the different parts of the quadriceps muscle, the rectus femoris muscle is the most superficial and the sole
biarticular, and it is the muscle that most frequently has injuries. The origin of the rectus femoris is by three different
tendons. The direct tendon origin is in the anteroinferior iliac spine. The indirect tendon origin comes from the
acetabular ridge. And the reflected tendon arise the major trochanter of the femur bone. These three different tendon
parts converge and muscular fibbers continue then, but each one of this origin form a part of the muscle. The direct
tendon follows down by a superficial aponeurosis which covers the anterior aspect of the proximal muscle (superficial
aponeurosis); the indirect tendon forms a sagittal-oriented band (also called central aponeurosis) that is located inside
the proximal muscle belly.
Our aim is to describe the human anatomy of the quadriceps muscle and its principal characteristics with special care for
the possibility of injuries.

Title:
Architecture of the Quadriceps Muscles

Abstract:
The session will consist of a detailed review of the structural anatomy and the functional implications, it will explore the
aspects of both the myokinematics and arthrokinematics influences on rehabilitation for such injuries, and how this can
further influence biomechanics and muscle physiology in the rehabilitation process.
This will then be applied in a real time example of case study of an Olympic Gold Medallist, who suffered a complete
rupture (80%) of both the long head and short head of Rectus Femoris, with a 10cm retraction. This injury was managed
conservatively and the athlete return to full competition to win a Olympic silver medal in 2012 and go on to break their
personal best time in the World Championships Final to win the Gold medal in 2013.
The lessons learnt from conservative management; to functional application of the science; to integration into sport
with specific return to function markers and ongoing sensitive management tools to ensure no re-injury at the
vulnerable site will be discuss and imparted onto the audience.

Title:
Quadriceps muscle Injuries: from injury day to Return To Play

Abstract:
In Australian football punt kicking, the foot-ball impact occurs without the ball touching the ground. Rectus femoris
strains may occur in the kicking cycle but before foot-ball contact. If quadriceps strains occurred due to foot-ball
impact, the furthest kicks would cause more injuries, whereas it is generally shorter kicks when running at top speed
that lead to quadriceps strain. The amount of foot-ball impact force is roughly proportional to the distance that the ball
travels, yet long kicks with a slow run-up do not tend to cause rectus femoris strain in Australian football. In soccer
football, goalkeepers generally do not get quadriceps strains, despite kicking the ball the furthest distance. They are also
rare in punters in American football and goalkickers in rugby union and league, where kicks for maximum distance are
often attempted. Finally there is evidence from Australian football that quadriceps strains are not related to ball
inflation pressure or wet weather (where the ball is heavier)1
. Video analysis of the stance leg during a running kick
shows the challenge for the quadriceps of slowing down the speed of body movement but with a slightly short step in
order to raise the hips to provide clearance for the kicking leg. Like the hamstring strain it is not clear whether the actual
muscle failure occurs during the ground contact phase or swing phase. As with the hamstring, the swing phase is
associated with the greatest muscle length (stretch), whereas the ground phase is associated with the greatest potential
impact of external force (ground reaction force). In contrast to the hamstring strain injury, in rectus femoris strain injury
the ground contact phase of risk precedes, rather than follows, the swing phase of greatest stretch.
Analysis of in vivo patella tendon forces with direct intratendinous measurement in jumping has shown high forces
during ground contact phases and minimal forces during swing phases 2
. If it is presumed both that internal rectus
femoris forces are “in phase” with patella tendon forces and that kicking, like jumping, would have higher patella
tendon forces during the ground contact phases, it is most likely that rectus femoris strains actually occur during
deceleration in the ground contact phase prior to the backswing on the kicking leg.

Title:
Rehabilitation of rectus femoris injuries. Experience at Sevilla FC

Abstract SESSION 5 (Linde & Brau)
The purpose of this presentation is to describe the rehabilitation treatment process received by a professional soccer
player who suffered a complete tear of rectus femoris, involving direct and indirect head of his left leg (shooting leg is
right side). The subject describes is a man 20 years old, 1,75 cm height and 71 kg weight. During the complete
rehabilitation and return to play process, that took a total period of 10 weeks until the reintroduction to normal training
with the group, we are going to focus in this presentation in describing the techniques applied regarding to
physiotherapy and regarding to strengthening in the gym.
When we talk about the treatment of physiotherapy, it has been based in many different therapeutical options, based in
lower limb manual manoeuvres, massage and stretching and elastification techniques basically, as well as the
application of hyperthermia in the specific segment during the scar solving process. In that treatment stage we will
introduce as well analytic muscle strengthening of the affected thigh, that will be done in the table. How we choose the
applied technique will depend on the moment of the injury evolution, and on the moment of the application, that
means before or after the workout. Regarding to strengthening stage, we describe the performed exercise’s evolution,
based on their functionality anb range of movement, with different king of machines or implements, as elastic
resistance bands, functional workout machines, pneumatic machines or instable surfaces, in example. We stand out in
this workout performed in the gym, the importance of combining strengthening with active tension stretching, by which
the player can achieve new barriers in range of motion by player’s own muscle contraction. About recovery measures
after training session or treatment, the most commonly applied were cryotherapy, combination of cold and hot water,
and presotherapy mainly.
Abstract SESSION 6 (Yanguas & Brau)
Quadriceps muscle injuries are common in professional football. Well design protocols of physiotherapy and controlled
specific football exercises during this time are a key point for a successful rehabilitation and to decrease the risk of
reinjuries.
We propose an example of rehabilitation in a grade 3 muscle tear of proximal rectus femoris in a professional football
player. We tried to introduce specific exercises as soon as possible if these are well tolerated and pain-free by the
player.

Title: Return to play in rectus femoris muscle injuries. Our experience with professional foot-
ball players

Traditionally water exercises have been used in the first stages of the rehabilitation due to their low impact
characteristics. We proposed the use of another surface, sand, to begin running and football specific exercises because
sand surface can offer lower impact training stimulus compared with grass and can limit muscle damage. In later stages,
strength (concentric and eccentric) has been running in an uphill/downhill ramp trying to reproduce functional specific
football movements during all the process. GPS have been used to record all the data to control de loads and the quality
of the training.
After three months the player returned to play without problems in a medical situation where the surgical treatment
had a lot of probabilities to be proposed.

Abstract:
Quadriceps injury and concretly its rehabilitation represents a major problem in modern football. The rectus femoris is
the most commonly injured muscle and cause more missed games and reinjure rates than do hamstring and groin
muscle injuries. In-depth knowledge around rectus femoris injuries together with a contextualized (football) approach
will allow us to develop a new practical rehabilitation model that will guide us to move through the treatment process
until return to sport.

Title:
New Rehabilitation concept applied to the rectus femoris injuries in football

Abstract:
The importance of muscle injuries in athletes is related to its personal cost, the injury rate, the injury's severity, the
reinjury risk and the availability of the athlete during competition. Hamstring strains are related to the speed and the
range of motion and they are widely studied because they are so common in athletes and footballers (50 - 70% of thigh
strains reported in the literature). 61% of thigh strains in pro-football players in FCB are related to hams, and 32% in
academy players. Adductor strains are typical in football, and they have been linked up to pubic dysfunctions.
Adductors are injured in 25-30% of thigh muscle strains, and this frequency is not related to age.
Rectus femoris (RF) strains appear during kick and severe changes in speed during the sprint. RF is directly involved in
football kicking by hip flexion and knee extension. The injury affects the structure of the injured muscle. RF injury rate
among FCB players varies depending on age, 43% of thigh strains in U-18 and 11% in pro. The prevalence of RF strains
increases from 8 to 13 years old and from 15 to 18 years old. But among the 13 to 15 players the RF strain rate is lower
because the skeletal maturity makes the epiphysis of the anterior inferior iliac spine more prone to avulsion.
RF strains in young players are important because they are so frequent. Its healing and scarring can affect the intrinsic
functions of connective and contractile tissue of the muscle.

Title:
The magnitude of the injury in relation to the age of the player

Abstract:
Rectus femoris injuries are common in sprinting and jumping athletes. Dr Pollock will discuss the British Athletics Muscle
Injury Classification published in the British Journal of Sports Medicine in 2014 with reference to its use in classifying
rectus femoris injuries in elite Track and Field. The British Athletics Muscle Injury Classification grades injuries from 0 to
4 based on MRI features, with Grades 1-4 including an additional suffix (‘a’, ‘b’ or ‘c’) if the injury is myofascial, musculo-
tendinous junction or intratendinous. In particular, injuries that extend into the tendon seem to take longer to RTP and
are associated with a higher reinjury rate.

Title:
Quadriceps Muscle Injuries: British Athletics classification

Abstract:
Physical exercise in the form of resistance training (RT) has consistently been shown to induce adaptive changes in
nervous system function that in turn contribute to the training induced increase in maximal contractile muscle force and
power. The adaptive plasticity in neural function with training has been evaluated by use of muscle electromyography
(EMG) measurements, including single motor unit recording and measurements of evoked spinal reflex responses (H-
reflex, V-wave) and corticospinal excitability by transcranial magnetic stimulation (TMS). Parallel increases in explosive
muscle strength (rate of force development: RFD) and EMG activity have been observed in the very initial contraction
phase (0-200 milliseconds) following RT. The specific neural adaptation mechanisms responsible for the training-induced
increase in RFD include increased spinal motoneuron firing frequency and elevated incidence of discharge doublets. In
addition, muscle fiber hypertrophy and changes in muscle architecture contribute to the training induced increase in
RFD. A neural regulatory mechanism that limits the recruitment and/or discharge rate of motor units has been
demonstrated to exist during maximal voluntary eccentric muscle contraction. Notably, this apparent inhibition in spinal
motoneuron activation during maximal eccentric (ECC) contraction can be downregulated by use of resistance training,
in turn leading to elevated levels of maximal ECC strength that are vital for an optimal athletic performance. In turn, the
above training induced changes in neuromechanical muscle function provide a strong fundament for achieving gains in
sprint and kicking performance, and for preventing overuse injury in muscles, tendons and joints. Further, in non-
athletes such as frail elderly adults similar adaptive responses can be evoked that result in an improved functional
capacity during activities of daily living, such as stair walking and chair rising. Thus, the adaptive plasticity in
neuromechanical function can be exploited to yield significant benefits in both athletes and non-athletes alike.

Per Aagaard serves a position as Professor in Biomechanics at the Institute of Sports Science and Clinical Biomechanics,
University of Southern Denmark. Overall taken his research activities have addressed the adaptive plasticity in
neuromuscular function and muscle morphology/architecture induced by training and detraining/inactivity, including
aging and immobilization. Specifically, a number of studies have been conducted to examine topics such as the effect of
resistance training on skeletal muscle morphology and neuromuscular function in young and aging adults, myogenic
stem cell activation with acute exercise and long-term training, muscle-aponeurosis-tendon function in vivo,
neuromechanical aspects of knee ligament (ACL) injury and subsequent rehabilitation, rehabilitation and prevention of
muscle-tendon-joint injury in exercise and sports, and exercise/training/biomechanical analysis in elite sports. Per

Title:
Neuromuscular plasticity in quadriceps function in response to training and
how this might affect sprinting ability and kicking performance

Abstract:
INDIRECT INJURY MECHANISMS
Rectus femoris (RF) injury causes severe pain in the anterior thigh when running or kicking a ball, though sometimes the
onset may be surreptitious. RF injury can be objectified by ultrasound (US) or magnetic resonance (MR).
There are several types of injuries with predictive values depending on their location.
AIIS injuries. The view of the Rectus Femoris origin with complementary tests is usually complex, both by MRI and US.
MR is considered to be the test of choice in this type of injury.
Central tendon injuries. These are the most frequent and characteristic RF injuries. In grade 1 a 'feather pattern' is
observed. In grade 2 there is more bleeding and the image may appear in a "bull’s eye". The characteristics of this sign
explain different degrees of evolution. Thus, in the early lesion there is edema and bleeding around the central tendon
that evolves into increased vascularization and scarring. When atrophy and fatty infiltration around the tendon are
observed, the lesion has usually been evolving over a very long period. US is useful both for diagnosing and monitoring
this type of injury.
Superficial injures. In the proximal lesions of the superficial aponeurosis, a small fluid collection is observed along the RF
anterior portion, between the anterior fascia and its muscle body.
Distal peripheral injuries.
The distal myotendinous ruptures affect the posterior fascia and may cause proximal muscle stump and interfascial
hematoma between the RF and vastus intermedius. Sometimes they can develop into a pseudocyst. Progressive
resorption allows a fibrous lamellar repair between the RF and the vastus intermedius. US allows evacuation of the
interfascial hematoma.
INJURIES BY DIRECT MECHANISM
The clinical study and exploration provide a basic classification. US allows lesion evolution monitoring and is therefore
the imaging test of choice whilst MR is reserved for doubtful cases or in the event of surgical advice.

Quadriceps Muscle Injurie diagnosis

COMPLICATIONS OF MUSCLE INJURY IN QUADRICEPS
The most characteristic quadriceps complication is Myositis ossificans (MO). It is a heterotopic ossification, i.e., an
abnormal formation of mature lamellar bone within the soft skeletal tissues where there is usually no bone. The
pathogenesis is unknown although it is usually a secondary occurrence from an initial muscle injury by direct
mechanism. In the quadriceps the muscle that is affected is the Vastus intermedius.

Abstract:
The Rectus Femoris is very important in football because the players sprinting and kicking the ball with this muscle.
The muscle injuries treated during three consecutive seasons in the Mutualitat de Futbolistes were: 2.209 in 2012-2013;
1.922 in 2013-2014 and 2.266 in 2014-2015.
The more often injured muscles are:
However, the rectus femoris injuries requiring surgical treatment are few.
From January 2015 to May 2016, the surgery was only required in 7 cases.
In the published series1
of 10 surgical cases treated from 1999 to 2009, it was already stated that the vast majority of
these injuries are solved with conservative treatment, needing surgery only in those cases when the results were not
satisfactory or when the type of rupture demanded it or the impossibility of sprinting and kicking.

Rectus femoris injuries: what and when?

The surgical techniques performed are:
Reattachment of the tendon when avulsed
Muscle-tendon suture when the injury is near to its insertion, 3 to 4 cm.
Total freedom and relaxation of the muscle when the injury is more than 4 cm distal to the tendinous insertion.
The sutures performed are always injected with leukocytes-free PRP (PRGF-Endoret®
) creating a favourable environment
for tissue regeneration.

Abstract:
Skeletal muscle represents a classic example of a structure-function relationship1
. Thus, structural studies of muscle
often inform its function. In the case of the quadriceps complex, the major structural feature of these muscles is their
design for high force production. Skeletal muscle architecture dominates a muscle’s force generating properties2
, and
the vastus lateralis, vastus medialis, and vastus intermedius have a highly pennated structure resulting in very large
cross-sectional area (CSA)3
. Specifically, the pennation angle of about 25°, the fiber length/muscle length ratio of about
0.25, and the CSA of about 25 cm2
predict that this is the largest combined muscle group in the human body.
Intraoperative sarcomere length measurements4
demonstrate unique roles for the vastus lateralis and vastus medialis
heads. Rectus femoris, as the only biarticular quadriceps plays a unique role it force distribution across the knee and
hip5,6
and may render it vulnerable to eccentric contraction-induced muscle injury.7,8
Finally, the fact that all four heads
of the quadriceps are approximately 50% type 1 (slow) fibers and are highly oxidative9
reflect the high level of use of this
muscle group as well as its potential for plasticity. These structural properties will be discussed in light of the injury and
rehabilitation of quadriceps muscles.

Title:
The Design of the Quadriceps Muscles

Abstract:
I present experiences of rectus femoris muscle injury operations. During years 1999 -2015 57 operations were done to
treat rectus femoris tears in 56 patients. One had a total avulsion of the muscle at AIIS on both sides with an interval of
1.5 years between operations. There were 24 rectus femoris muscle avulsions at AIIS, 15 total and 9 subtotal tears. The
mean age of these patients was 23.5 years (range 15 – 31 years). All were men. There were 19 professional soccer
players in the series. 2 were soccer players at a lower level and 3 represented 110 hurdles, and sprinting. These all were
treated with refixation using Mitek´s superanchors or Juggerknot anchors. The operation was done in less than three
weeks in 17 cases and between 4 and 15 weeks in 7 cases. In three cases calcification (small bony or periost avulsion)
was removed. The final result was good or excellent in 20 cases and moderate in four cases.
Of the six proximal tears five were recurrent tears and after operative treatment the results were good only in three
cases, others had a moderate result. In three cases bone anchor was used in addition to suturation. Three times
suturation and proximal central tendon repair/lengthening was done.
27 operations were done to the total tears in the middle and distal third of the rectus femoris muscle. In all patients
symptoms continued after the initial conservative treatment. The patients complained continued pain, weakness,
spasms and deficient control of the leg during sports. There were 12 soccer players, 11 track and field athletes and 4
indoor ball players in this series. Two of them were females. The mean age of the patients was 27.1 years (range 19 – 46
years). The final results were good or excellent in 20 cases. Others had a moderate result. Muscle gap often remained,
but did not affect to end result.

Abstract (Linde & Brau)
The purpose of this presentation is to describe the rehabilitation treatment process received by a professional soccer
player who suffered a complete tear of rectus femoris, involving direct and indirect head of his left leg (shooting leg is
right side). The subject describes is a man 20 years old, 1,75 cm height and 71 kg weight. During the complete
rehabilitation and return to play process, that took a total period of 10 weeks until the reintroduction to normal training
with the group, we are going to focus in this presentation in describing the techniques applied regarding to
physiotherapy and regarding to strengthening in the gym.
When we talk about the treatment of physiotherapy, it has been based in many different therapeutical options, based in
lower limb manual manoeuvres, massage and stretching and elastification techniques basically, as well as the
application of hyperthermia in the specific segment during the scar solving process. In that treatment stage we will
introduce as well analytic muscle strengthening of the affected thigh, that will be done in the table. How we choose the
applied technique will depend on the moment of the injury evolution, and on the moment of the application, that
means before or after the workout. Regarding to strengthening stage, we describe the performed exercise’s evolution,
based on their functionality and range of movement, with different king of machines or implements, as elastic
resistance bands, functional workout machines, pneumatic machines or instable surfaces, in example. We stand out in
this workout performed in the gym, the importance of combining strengthening with active tension stretching, by which
the player can achieve new barriers in range of motion by player’s own muscle contraction. About recovery measures
after training session or treatment, the most commonly applied were cryotherapy, combination of cold and hot water,
and presotherapy mainly.

Title:
Rehabilitation of rectus femoris injuries. Experience at Barcelona FC

Abstract:
For many years muscle injuries have been causing athletes time loss and being a common situation to face for sport
physicians, indeed they are still not well known. The muscles most commonly involved are biarticular muscles with high
proportion of fast-twitch fibers and complex architecture. In professional soccer, between 92% and 97% of all muscle
injuries are located in the lower extremity: hamstrings (28%-37%), quadriceps (19%-32%), adductors (19%-23%), and
calf muscles (12%-13%).
How to classify muscle injuries is a main stone to better understand and manage them; at present it is the reason of a
deep discussion far from consensus. There are several reasons to explain why we are still debating about how to classify
muscle injuries; a failure to communicate it is being one of the main reasons in our opinion due to ambiguous
definitions in several fields. Our goal is to improve communication between health professionals when talking about
muscle injuries with a new muscle injuries classification. Our proposal describes the injury anatomical location and its
relationship with the extracellular matrix (ECM), it evaluates the ECM damage, offers several grading options, and
provides information about the injury chronology.
The proposal is based on expert opinions but incorporating the existing scientific evidence about muscle; we organize
and resume this concept in a 4 letters acronym structure. We offer a new classification system for muscle injuries
involving the mechanism of injury, location of injury, grading of severity, and number of previous muscle injuries, to
grade it and describe its chronology. It also has a flexible and open structure capable to adapt to future knowledge.

Title:
Rectus Femoris: a new evidence-based and expert consensus-based
classification with clinical application

Abstract:
Quadriceps muscle injuries are common in professional football. Well design protocols of physiotherapy and controlled
specific football exercises during this time are a key point for a successful rehabilitation and to decrease the risk of
reinjuries. We propose an example of rehabilitation in a grade 3 muscle tear of proximal rectus femoris in a professional
football player. We tried to introduce specific exercises as soon as possible if these are well tolerated and pain-free by
the player. Traditionally water exercises have been used in the first stages of the rehabilitation due to their low impact
characteristics. We proposed the use of another surface, sand, to begin running and football specific exercises because
sand surface can offer lower impact training stimulus compared with grass and can limit muscle damage. In later stages,
strength (concentric and eccentric) has been running in an uphill/downhill ramp trying to reproduce functional specific
football movements during all the process. GPS have been used to record all the data to control de loads and the quality
of the training. After three months the player returned to play without problems in a medical situation where the
surgical treatment had a lot of probabilities to be proposed.
