Context: Chronic Ankle Instability is a condition that has continued to be a problem in athletes. Additional rehabilitation protocols are still being evaluated to alleviate reoccurring ankle sprains. Graston Technique is an instrument-assisted soft-tissue mobilization that assists in the release of scar tissue and facial restriction. Objective: To examine the effects of Graston Technique compared to a SHAM with outcome measures of subjective function, balance, and range of motion in collegiate athletes with chronic ankle instability (CAI). Design: Pretest/posttest. Participants: Sixteen collegiate athletes with a history of chronic ankle instability. Participants were randomly assigned to a treatment (4 males, 4 females, weight: 73.43 ± 18.18 kg, height: 177.8 ± 7.68 cm, age: 20.0 ± 1.07 y) and control group (4 males, 4 females, weight: 80.25 ± 28.81 kg, height: 177.53 ± 11.30 cm, age: 19.75 ± .886 y). Outcome Measures: FAAM and FAAM Sport Subscale, Balance Error Scoring System, and Weight Bearing Lunge. Results: There were no significant differences between the treatment and control groups. Both the treatment and control groups significantly improved in subjective function, balance, and range of motion. Conclusion: Based on the current results Graston Technique was no more effective at improving subjective function, balance, and range of motion in collegiate athletes compared to SHAM treatment. Doing light massage to the lower extremity was as effective at improving outcomes as Graston Technique.
