Bodywork Application and Physiology Flashcards

During a deep tissue session, a client reports a sudden sharp, shooting pain radiating down the posterior thigh after sustained pressure was applied to the piriformis. Which neurological structure is most likely being compressed, and what is the most appropriate immediate response?

Answer: The sciatic nerve; cease pressure immediately, reassess position, and apply gentle effleurage proximal to the site

The piriformis lies directly over the sciatic nerve, and in approximately 15% of individuals the nerve passes through the muscle belly. Sustained compressive pressure can provoke sciatic nerve irritation, producing sharp radiating pain along its pathway. The correct response is to immediately remove pressure, reassess the client's comfort and positioning, and transition to gentle effleurage proximal to the area to restore circulation without further nerve compression.

A massage therapist is working with a post-surgical client who had a knee meniscectomy six weeks ago. The surgeon has cleared the client for massage, but the therapist notices significant quadriceps atrophy and pitting edema just proximal to the patella. Which physiological mechanism best explains the edema in this location, and what technique is contraindicated?

Answer: Lymphatic stasis due to disrupted capillary filtration; deep effleurage directly over the edematous tissue is contraindicated

Post-surgical pitting edema proximal to the patella reflects disrupted lymphatic and capillary exchange secondary to surgical trauma and reduced muscle pump activity from quadriceps atrophy. Direct deep effleurage over pitting edema is contraindicated because it can rupture fragile capillary walls and increase local tissue damage. Manual lymphatic drainage with light, superficial strokes moving fluid proximally toward functioning lymph nodes is the appropriate approach.

A practitioner applies sustained myofascial release to the thoracolumbar fascia for 90 seconds. The client reports a spreading warmth and gradual softening of the tissue before any significant movement occurs. This response is primarily attributed to which physiological phenomenon?

Answer: Thixotropy, in which ground substance shifts from a gel to a sol state under sustained mechanical input

Thixotropy describes the property of certain gels — including the proteoglycan-rich ground substance of fascia — to become more fluid (sol state) under sustained mechanical stress such as heat and slow pressure. The reported warmth and progressive softening without a stretch reflex response are hallmark signs of this ground substance phase change. Autogenic inhibition and reciprocal inhibition are neuromuscular mechanisms involving muscle spindles and GTOs, not fascial ground substance, and piezoelectricity, while real in collagen, does not cause the diffuse warmth-and-softening pattern described.

When performing prone cervical traction on a client with a known diagnosis of cervical spondylosis at C5-C6, which specific contraindication assessment finding would require the therapist to immediately discontinue the technique?

Answer: Onset of upper extremity paresthesia or weakness during the procedure

Cervical spondylosis involves osteophyte formation and potential disc compromise at the affected level. Traction that produces upper extremity paresthesia or weakness indicates nerve root compression or cord involvement, which represents an acute neurological red flag. Continuing the technique under these circumstances risks serious, potentially permanent neurological injury. Stiffness that improves, mild postural changes, and transient trigger point activity are not neurological warning signs requiring technique cessation.

A therapist is treating a competitive cyclist for chronic iliotibial band syndrome. Despite consistent work on the IT band directly, symptoms persist. Advanced understanding of IT band anatomy suggests this outcome is likely because:

Answer: The IT band is largely avascular dense connective tissue with minimal contractile cells, making it physiologically resistant to lengthening; addressing the TFL and gluteus maximus neuromotor patterns is more effective

Current research demonstrates that the iliotibial band has a tensile strength approaching that of a ligament and contains very few fibroblasts capable of remodeling under manual pressure alone. The 'band' does not contract or significantly elongate in response to massage or stretching. ITBS is more accurately understood as a compression syndrome at the lateral femoral epicondyle driven by altered hip abductor and external rotator motor control — particularly TFL overactivation and gluteus medius inhibition. Effective treatment targets these proximal neuromuscular contributors rather than the band itself.

During a lymphatic drainage session on a client with secondary lymphedema of the left arm following axillary node dissection, the therapist should begin the sequence in which order to maximize physiological efficacy?

Answer: Activate the ipsilateral inguinal nodes first, then open anastomotic pathways at the left lateral trunk before treating the left arm

In secondary lymphedema following axillary node dissection, the ipsilateral axillary basin is compromised or absent. Effective MLD protocol requires first activating an alternative drainage terminus — the ipsilateral inguinal nodes — and then opening the axillo-inguinal anastomotic pathways along the lateral trunk to create a functional rerouting channel before moving fluid from the affected limb. Working distally first without opening this collateral pathway would push fluid into an already-obstructed region. Deep petrissage is absolutely contraindicated in lymphedema as it can damage remaining lymphatic capillaries.
