BACKGROUND

In-person hand therapy is commonly prescribed for rehabilitation after thumb carpometacarpal (CMC) arthroplasty but may be burdensome to patients because of the need to travel to appointments. Asynchronous, video-assisted home therapy is a method of care in which videos containing instructions and exercises are provided to the patient, without the need for in-person or telemedicine visits. The purpose of the present study was to evaluate the effectiveness of providing video-only therapy (VOT) as compared with scheduled in-person therapy (IPT) after thumb CMC arthroplasty.

METHODS

We performed a single-site, prospective, randomized controlled trial of patients undergoing primary thumb CMC arthroplasty without an implant. The study included 50 women and 8 men, with a mean age of 61 years (range, 41 to 83 years). Of these, 96.6% were White, 3.4% were Black, and 13.8% were of Hispanic ethnicity. The primary outcome measure was the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) score. Subjects in the VOT group were provided with 3 videos of home exercises to perform. Subjects in the control group received standardized IPT with a hand therapist. Improvements in the PROMIS UE score from preoperatively to 12 weeks and 1 year postoperatively were compared.

RESULTS

Fifty-eight subjects (29 control, 29 experimental) were included in the analysis at the 12-week time point, and 54 (27 control, 27 experimental) were included in the analysis at the 1-year time point. VOT was noninferior to IPT for the PROMIS UE score at 12 weeks and 1 year postoperatively, with a difference of mean improvement (VOT - IPT) of 1.5 (95% confidence interval [CI], -3.6 to 6.6) and 2.2 (95% CI, -3.0 to 7.3), respectively, both of which were below the minimal clinically important difference (4.1). Patients in the VOT group potentially saved on average 201.3 miles in travel.

CONCLUSIONS

VOT was noninferior to IPT for upper extremity function after thumb CMC arthroplasty. Time saved in commutes was considerable for those who did not attend IPT.
