Use of a shoulder abduction brace after arthroscopic rotator cuff repair: A study on gait performance and falls.

Background: Fall prevention is essential in patients after arthroscopic rotator cuff repair because of the high risk of re-rupture. However, there are no reports related to falls that occur during the early postoperative period, while the affected limb is immobilized. Objectives: This study assessed gait performance and falls in patients using a shoulder abduction brace after arthroscopic rotator cuff repair. Study design: Prospective cohort and postoperative repeated measures. Methods: This study included 29 patients (mean age, 67.17.4years) who underwent arthroscopic rotator cuff repair followed by rehabilitation. The timed up and go test, Geriatric Depression Scale, and Falls Efficacy Scale were measured, and the numbers of falls were compared between those shoulder abduction brace users and patients who had undergone total hip or knee arthroplasty. Results: In arthroscopic rotator cuff repair patients, there were significant improvements in timed up and go test and Geriatric Depression Scale, but no significant differences in Falls Efficacy Scale, between the second and fifth postoperative weeks (p<0.05). Additionally, arthroscopic rotator cuff repair patients fell more often than patients with total hip arthroplasty or total knee arthroplasty during the same period. Conclusion: The findings suggest that rehabilitation in arthroscopic rotator cuff repair patients is beneficial, but decreased gait performance due to the immobilizing shoulder abduction brace can lead to falls. Clinical relevance Although rehabilitation helps motor function and mental health after arthroscopic rotator cuff repair, shoulder abduction brace use is associated with impaired gait performance, high Falls Efficacy Scale scores, and risk of falls, so awareness of risk factors including medications and lower limb dysfunctions is especially important after arthroscopic rotator cuff repair.
