Strain-Counterstrain treatment of piriformis muscle
Participant will lay prone on table with affected leg close to edge of table. Piriformis muscle tender point is identified and palpated. Then patient leg is passively moved off table and passive hip flexion, abduction, and possible internal/external rotation is added to reduce tender point by 70% or more. This is done passively. This position is held for 90 seconds and then participant is passively returned back to neutral prone position with leg on table. Tender point is palpated again to reassess for change in pain (using subjective visual analog scale). An algometer is also used pre and post to assess objective change in pressure pain threshold.
