Brief Summary

Objective. To determine the effectiveness of instrument assisted soft tissue mobilization and horizontal adduction stretch in CrossFit practitioners' shoulders.

Setting: Acero CrossFit center, city of Toledo (Spain) Design: Randomized, single-blind pilot study, with follow-up period. Participants: Twenty-one subjects of both sexes, being regular CrossFitters and in the age range of 18 to 40 years.

Intervention: The experimental group (n = 11) received 30 seconds of stretching with isometric contraction of 5 seconds and instrument assisted soft tissue mobilization. The control group (n = 10) received only 40 seconds of instrument assisted soft tissue mobilization. Each session lasted 2 to 5 minutes, 2 days a week, over a period of 4 weeks, prior to each workout.

Main Outcome measures: Shoulder internal rotation and horizontal adduction (digital inclinometer), and posterior shoulder stretch perception (Park scale) were evaluated.

Study Groups

Experimental

In the experimental group, instrument-assisted soft tissue mobilization techniques and post-isometric horizontal adduction stretches were performed. The technique lasted 20 seconds in a parallel direction and 20 seconds in a perpendicular direction on the posterior shoulder and scapula muscles. While the dominant hand was used to hold the instrument, the other hand was used to tighten the skin medially to ensure an even area of treatment.

Group Type: EXPERIMENTAL

Instrument-assisted

Intervention Type: OTHER

instrument-assisted soft tissue mobilization techniques (applied with the subject in prone position. The technique lasted 20 seconds in a parallel direction and 20 seconds in a perpendicular direction on the posterior shoulder and scapula muscles. While the dominant hand was used to hold the instrument, the other hand was used to tighten the skin medially to ensure an even area of treatment) and post-isometric horizontal adduction stretches (carried out with the subject in the supine position, passively adducting the arm horizontally until the first motion barrier and performing active horizontal abduction for 5 seconds at 25% of force. The arm was then taken to the new motion barrier, repeating this process three times).

Control

Control group only underwent soft tissue mobilization. With the subject in the supine position, passively adducting the arm horizontally until the first motion barrier and performing active horizontal abduction for 5 seconds at 25% of force. The arm was then taken to the new motion barrier, repeating this process three times.
