Pelvic Floor and Women's Health Flashcards
Pelvic Floor and Women’s Health
bony boundaries of the pelvic floor
- anterior: pubic symphysis
- anterolateral: inf pubic ramus
- lateral: ischial rami and ischial tubeorsity
- posterolateral: scrotuberous ligamet
- posterior: coccyx

triangles of the pelvic floor
- urogenital triangle
- anal triangle
Pelvic Floor and Women’s Health
blood supply to the pelvic floor
- 2 pudendal arteries
- internal pudendal artery
- labial veins
Pelvic Floor and Women’s Health
The pelvis is innervated mainly by the sacral and coccygeal spinal nerves and the pelvic part of the
autonomic nervous system.
Pelvic Floor and Women’s Health
the lumbar plexus branches to the pelvis
- genitofemoral
- ilioinguinal
Pelvic Floor and Women’s Health
the sacral plexus branches
- pudendal
- levator ani
Pelvic Floor and Women’s Health
Lumbosacral nerves
- iliohypogastric (T12-L1)
- ilioinguinal nerve (L1)
- genitofemoral nerve (genital branch) (L1-L2)
- lateral femoral cutaneous nerve (perineal branch) (L2-L3)
- pudendal nerve (S2-S4)
- obturator L2-L4
Pelvic Floor and Women’s Health
detrusor muscle
Pelvic Floor and Women’s Health
Sympathetic input to the the pelvis:
- Provides motor innervation to vascular smooth muscle
- Provides constant tone in internal sphincters.
- Detrusor relaxation for filing & storage
Pelvic Floor and Women’s Health
Parasympathetic input to pelvic floor
- Provides motor & sensory to innervation to bladder
- Responsible for relaxation of internal anal sphincter
- Detrusor contraction, promotes bladder emptying
- Blood vessel dilation
- Erection of clitoris or penis
Pelvic Floor and Women’s Health
70% of the muscle fibers in the pelvic floor are type…
type I (slow twitch)
30% are type II (fast twitch)
Pelvic Floor and Women’s Health
Layer 1 (Urogenital Triangle) muscles of the pelvic floor
- perineum or superficial pouch
- bulbocavernosus (bulbospongiosus in men)
- ischiocavernosus
- superficial transverse perineal
- external anal sphincter
Pelvic Floor and Women’s Health
Layer 2 (Urogenital Diaphragm) muscles of the pelvic floor
- urethral sphincter (in men)
- compressor urethra (in men)
- sphincter urethral vaginalis
- deep transverse perineal
- perineal membrane
Pelvic Floor and Women’s Health
Layer 3 (Pelvic Diaphragm) muscles of the pelvic floor
- levator ani muscle (pubococcygeus, puborectalis, iliococcygeus & coccygeus)
- Obturator internus
- Piriformis
Pelvic Floor and Women’s Health
Function of the PFM
- Support of the pelvic viscera
- Sphincteric (bladder & bowel control)
- Sexual functions
Pelvic Floor and Women’s Health
Abdominal Canister by Dianne Lee
- Balance bet. the diaphragm, PFM, transverse abdominus (TrA), other abdominal muscles & multifidus.
- Transmits intra-abdominal pressure during activities
- Keeps alignment of pelvis.
- Keep joints in optimal form closure.
- Keep optimal force closure.

Pelvic floor dysfunction: Janda’s principles
Muscle contraction properties change in response to inflammatory process or pain → hypertonicity → impaired contraction & relaxation (coordination issues) → trigger points and muscle guarding development
Pelvic Floor and Women’s Health
Musculoskeletal dysfunction of the PFM that may be the 1° cause of pelvic pain in response to pathology in the:
urologic, gynecologic, &/or gastroenterologic
Pelvic Floor and Women’s Health
Pelvic floor dysfunction is often is a response to a 1° pain generator arising from…
bladder, rectal or vaginal pathology.

Clinical Pearl of Wisdom in Treating PFD
Stretch wht’s tight → strengthen what’s weak → perform neuromuscular reeducation
(Note: “sometimes is weak from reciprocal inhibition.” Dr. Q)
Pelvic Floor and Women’s Health
Postural Muscles Facilitation: Gets Shortened
(NOTE: Get shortened from excessive contraction)
- iliopsoas
- QL
- pectineus
- piriformis
- TFL
- lateral quad
- rectus femoris
- hamstrings
- short adductors
- PELVIC FLOOR
Pelvic Floor and Women’s Health
Dynamic Muscles Inhibition: gets weak
- multifidi
- gluteals
- long adductors
- rectus abdominus
- TrA
Pelvic Floor and Women’s Health
What is muscle tone
Resistance to displacement at rest
Pelvic Floor and Women’s Health
Pelvic floor muscle tone is affected by…
Hormones (pregnancy, menstrual cycle, menopause)
Pelvic Floor and Women’s Health
True or false: pelvic muscle tone helps categorized pelvic floor dysfunction diagnoses
True (hypertonic, hypotonic, etc)
Pelvic Floor and Women’s Health
adequate tension in response to the forces working on the PF at any given moment in time
Normal muscle tone
Pelvic Floor and Women’s Health
too little tone, lax, weak
Hypotonic PFM
Pelvic Floor and Women’s Health
Increase in PFM resting tone (PFM in a constant state of contraction) + impaired relaxation of the PFM leads to muscle fatigue
Hypertonic PFM
Pelvic Floor and Women’s Health
No icrease in PFM resting tone. PFM does NOT feel “springy” during palpation. PFM feels like “firm shelves or violin strings.” + active trigger points. Weakness. Delayed relaxation.
Shortened PFM

APTA category: supportive
- Urinary incontinence
- fecal incontinence
- pelvic organ prolapse
- pelvic muscle weakness
- disuse, atrophy
- neurologic dysfunction
Pelvic Floor and Women’s Health

Pelvic Floor and Women’s Health
What is the APTA pelvic floor dysfunction category of the following presentation?
Pain lasting 6 mos or longer or pelvic pain not relieved by meds or other measures, altered physical functions, signs of depression (esp sleep disturbance), altered family roles
Chronic Pelvic Pain
Pelvic Floor and Women’s Health
Condition in which involuntary loss of urine is a social or hygienic problem & is objectively demonstrable (definition by International Continence Society).
urinary incontinence
Pelvic Floor and Women’s Health
Stress incontinence
- Symptoms: Leaking with cough, laugh, or sneeze
- Mechanism: Urethral hyper mobility, pelvic floor damage damage, chronic stress to pelvic floor, decreased estrogen
Pelvic Floor and Women’s Health
Urge incontinence:
- Symptoms: leaking when hearing running water, “key in the door” (go all the time), frequent urination
Pelvic Floor and Women’s Health
Mixed incontinence
- Possible mechanism: combined mechanisms of stress & urge
- Symptoms: Combined cues
Pelvic Floor and Women’s Health
Decreased contractility of detrusor muscle, urethral obstruction. Patient presents with chronic dribbling of urine, urinary frequency
Overflow incontinence
Pelvic Floor and Women’s Health
Risk factors for Urinary Incontinence
- PFM weakness
- Pregnancy, vaginal delivery, episiotomy
- Immobility associated with degenerative disease
- Estrogen depletion
- Medications (diuretics)
- Chronic cough/sneezing
- Constipation
- Obesity
- High impact exercise

PFM grades
- 0 = no contraction
- 1 = flick of muscle detected
- 2 = weak squeeze
- 3 = Fair squeeze with “definite lift” (moving in upward direction)
- 4 = good squeeze with repeatable hold and lift
- 5 = strong, solid, repeatable squeeze and lift
