The document details a patient's medical history and symptoms, including persistent pelvic pain and a history of low back issues, exacerbated by physical activities. It outlines the anatomy and functions of the pelvic floor muscles, discusses pelvic floor dysfunction types, prevalence of symptoms among different populations, and common diagnoses associated with pelvic pain. Treatment recommendations include various therapies, exercises, and postural education to address the dysfunctions.
Pelvic floor muscle and dysfunctions
- 2. Chief Complaints: Constant, aching suprapubic and low back pain. Intermittent left LE radicular pain to calf. Intermittent vaginal pressure, severe cramping, painful defecation and increased urinary urgency. Worse with running and jogging. Pain Scale: 6/10 (rest) / 10/10 (activity)
- 3. History: While catching a football pass four years prior, the pt. felt a sudden, sharp vaginal pain which persisted and progressed to the pubic and rectal regions. Symptoms have progressively worsened. PMH: Long history of low back pain. Treated by chiropractor (x 3yrs), PT, acupuncture and massage therapy with minimal benefit. MRI: (+) L 4-5 HNP
- 4. The pelvic floor consists of five layers: III – Pelvic Diaphragm / Levator Ani Muscles (Deep): 1. Pubococcygeus 2. Puborectalis 3. Iliococcygeus 4. Ischiococcygeus (Coccygeus)
- 5. III – Levator Ani Muscles (Deep): 1. Pubococcygeus: Arises from the dorsal surface of the pubic bone and obturator internus fascia, inserts on the anococcygeal and perineal bodies, anal wall. Forms a hammock to support the urethra, vagina and rectum. Pulls the rectum toward the pubic bone.
- 6. III – Levator Ani Muscles (Deep): 2. Puborectalis: Arises from the medio-lateral, dorsal surface of the pubic bone, blends with the lateral walls of the anus and rectum, and inserts at the external anal sphincter and anococcygeal body. Controls descent of feces by elevating and constricting anal canal.
- 7. III – Levator Ani Muscles (Deep): 3. Iliococcygeus: Arises from the ischial spine and fascia of obturator internus, inserts to the anococcygeal body, anal wall and the coccyx. Pulls the vagina and rectum toward the pubic bone. Most widely recognized source of peri-anal referred pain to the sacrum, coccyx, rectum, vagina and lumbar spine.
- 8. III – Levator Ani Muscles (Deep): 4. Ischiococcygeus (Coccygeus): Originates on the ischial spine and inserts on the caudal aspect of the sacrum and the coccyx. Provides tension to the pelvic floor, but not truly part of levator ani. Pulls the coccyx forward and stabilizes the sacroiliac joint. Innervated by ventral rami S4-S5
- 10. Supportive: to the pelvic/abdominal organs. Elevates the pelvic floor, resisting increases in intra-abdominal pressure. Sphincteric: Relaxes and contracts the urethral, vaginal and rectal openings. Sexual: Maintains clitoral erection, provides tone and proprioception to the vaginal wall.
- 11. Two types of pelvic floor dysfunctions: 1. Hypertonus Dysfunctions (pain) - 15% of women have chronic pelvic pain. - Persistent or recurrent pelvic pain (> 3 mos) associated with symptoms of lower urinary tract, sexual, bowel or gynecological dysfunction. No proven infection or obvious pathology. - More common in women 26-30 (Steege, 1996) - Hypertonicity of the PFM often arises in young, very fit women with a hypertonic abdominals, preventing PFM relaxation.(Sapsford et al 2001)
- 12. 2. Supportive Dysfunction (weakness) Incontinence (UI) and Prolapse - Prevalence rates: 10-55% general population 28-49% HS/college athletes 52% elite athletes. (Thyssen et al, 2002) - Athletic activity can affect the development of (UI), depending on the extent of intra-abdom pressure and the strength of impact forces involved. (Bourcier et al. 1996) - Highest prevalence in sports involving high impact such as gymnastics, track and field and some ball games. (Bo, 2004)
- 13. Symptoms: Primarily PAIN! Lumbar, perivaginal, perirectal, lower abdomen, coccygeal, posterior thigh. Vulvar/clitoral burning Dyspareunia (46% women-Steege, 1996) Constipation Common Diagnoses: Vulvodynia, interstitial cystitis, levator ani synd, coccydynia, pudendal neuralgia
- 15. 1. Piriformis: Can compromise pudendal nerve. Refers pain into SI region, laterally to buttocks/posterior hip, 2/3 posterior thigh. 2. Obturator Internus: Tendinous attachment with levator ani. Refers pain into vagina, occasionally to posterior thigh, feeling of “fullness” of rectum.
- 16. 3. Hip Adductors: 1. Adductor Magnus : Refers pain deep into groin, pubis, vagina, rectum. Usually “sharp, shooting” pain. 2. Pectineus: Refers pain deep into groin, anterior hip joint, below inguinal ligament.
- 17. Assess lumbar spine, SI joint, hips Lower quarter muscle strength, tone and length Lower quarter neuro screen Assess pelvic floor muscles External and internal digital exam Sensation Symmetry Tone Strength
- 19. Tenderness to palpation: (Severe) pubic symphysis, lower abdom, pirif, levator ani mus; (Mod) lumbar L3-5, sacrotuberous lig, obturator int, sacrococcygeal region. ROM: Minimal limitation in trunk ext. MMT: R LE – 5/5; L LE – 4/5 Neural: ANTT L sciatic nerve, myotomal weakness L4-S1, Diminished L DTR Structural: R/L Backward sacral torsion Left posterior innominate, lumbar rot. right
