Manual palpation group
Deep dry needling group
For the manual palpation group, the reference position will be a lateral position, lying on the non affected shoulder while the affected side will be explored. The arm and elbow are flexed 90° resting on a pillow and legs placed with 90° hip and knee flexion to stabilize the body, with the head resting on a pillow to maintain body alignment. The physiotherapist will be in front of the participant and carried out the examination with flat palpation using the thumb to identify soreness taut band tried to elicit local twitch response and referred pain in the infraspinatus area. First, three attempts will be made to elicit an local twitch response (LTR) using snapping palpation if a response will be obtained. After LRT, referred pain could also be evoked by palpation.
For the deep dry needling group, the reference position will be a lateral position, lying on the non affected shoulder while the affected side will be explored. The arm and elbow are flexed 90° resting on a pillow and legs placed with 90° hip and knee flexion to stabilize the body, with the head resting on a pillow to maintain body alignment. The physiotherapist will be in front of the participant and carried out the examination with flat palpation using the thumb to identify soreness taut before making the needle insertion. Sterile stainless steel needles (length 40mm/caliber 0.32 with a cylindrical plastic guide) will be used.
