Summary
The PROMIS-9 UE Physical Function short form shows moderate ability to track improvements in two-handed function after upper limb prosthesis use. This validated the instrument
Area of Science:
- Rehabilitation Medicine
- Prosthetics and Orthotics
- Outcome Measurement
Background:
- Upper extremity physical function is crucial for rehabilitation in individuals with limb amputation.
- The PROMIS-9 UE Physical Function short form is a new tool for assessing this population.
- Its responsiveness to prosthetic intervention requires evaluation.
Purpose of the Study:
- To assess the PROMIS-9 UE Physical Function short form's ability to detect changes in bimanual function.
- To evaluate responsiveness after patients receive an upper limb prosthesis.
Main Methods:
- Retrospective chart review of PROMIS-9 UE scores (April 2016 - February 2024).
- Included participants with pre- and post-prosthesis data.
- Analyzed 124 individuals (mean age 43.4 years).
Main Results:
- Significant improvement in PROMIS-9 UE scores post-prosthesis (25.3 to 29.5, p < 0.001).
- Moderate responsiveness (SRM = 0.6) to prosthetic intervention.
- Linear mixed models confirmed significant post-intervention changes.
Conclusions:
- The PROMIS-9 UE Physical Function instrument demonstrates moderate clinical utility.
- It effectively captures patient progress following upper limb prosthesis intervention.
