Abstract
Abstract
Objective
The purpose of this study was to determine the feasibility, reliability, validity, and responsiveness of the Timed Functional Arm and Shoulder Test (TFAST) in patients with shoulder problems.
Methods
This study was a repeated-measures clinical measurement observational cohort study. A total of 104 patients who were symptomatic participated in this study. The TFAST was collected as part of an patient’s outpatient physical therapist care at 6 different sites. The test and data collection were performed at 3 time points: baseline (initial evaluation), follow-up at the patient’s first return visit within 7 days of evaluation, and discharge at the patient’s final visit for care.
Results
All participants were able to perform the TFAST at baseline, with 1 exception, and 67 participants completed data collection at all 3 time points. There were no adverse effects in any participant related to performing the TFAST. Intrarater intersession reliability, reported as ICC(2,1), was 0.91 (95% CI = 0.79–0.95). The mean difference in TFAST scores for the affected arm was 23.2 repetitions (77.4 at baseline to 100.6 at discharge). The Cohen d effect size was 1.02, and the standardized response mean was 0.95. The minimal clinically important difference was determined to be 21 repetitions.
Conclusion
The TFAST seems to be feasible and appropriate for use in a wider population than other existing shoulder performance measures. The TFAST has demonstrated adequate reliability, validity, and responsiveness in patients with shoulder problems. Clinicians may consider using the TFAST to objectively assess patient performance.
Impact
The TFAST may be used to expand measurement of objective shoulder performance in a wide population of patients with shoulder problems. This test may provide information beyond an patient’s self-report and contribute to clinical decision-making.
