Summary
The Upper Extremity Function Scale (UEFS) shows promise in assessing daily function and quality of life for individuals with multiple sclerosis (MS). This patient-reported outcome can complement existing tests like the Nine-Hole Peg Test (9-HPT).
Area of Science:
- Neurology
- Rehabilitation Medicine
- Quality of Life Research
Background:
- Upper extremity (UE) impairments significantly impact daily activities and quality of life (QOL) in individuals with multiple sclerosis (iMS).
- The Nine-Hole Peg Test (9-HPT) is commonly used for UE function assessment but may not capture functional limitations in daily tasks or be suitable for all iMS.
- Alternative measures like the Upper Extremity Function Scale (UEFS) and Action Research Arm Test (ARAT) are explored for a more comprehensive UE assessment.
Purpose of the Study:
- To quantitatively assess the relationships between UE function measures (UEFS, ARAT, 9-HPT).
- To determine if these UE function measures correlate with QOL, specifically using the MS Quality of Life-54 (MSQOL-54).
- To identify differences in UE function measures based on employment status among individuals with MS.
Main Methods:
- A prospective, descriptive correlational study involving 112 individuals with MS (iMS).
- Inclusion criteria: confirmed MS or clinically isolated syndrome, age ≥ 18 years, and ability to self-consent.
- Statistical analyses included Spearman's correlation coefficient and Kruskal-Wallis tests using SPSS.
Main Results:
- A moderate correlation was observed between the ARAT and 9-HPT scores for the more impaired hand (r = -0.51, p < 0.001).
- The UEFS showed a moderate correlation with the physical health composite scores (PHCSs) of the MSQOL-54 (r = -0.59, p < 0.001).
- Significant differences in performance on ARAT, 9-HPT, and UEFS were found between employed individuals and those on long-term disability (p < 0.007).
Conclusions:
- The UEFS, a patient-reported outcome, demonstrates a moderate correlation with QOL measures and can complement existing UE function assessments.
- Further research is needed to ascertain which UE function measure or combination of measures is most sensitive to changes over time in iMS.
- Findings suggest UEFS may offer valuable insights into the functional status and QOL of individuals with MS.
