Assessing active thumb palmar and radial abduction in persons with thumb carpometacarpal osteoarthritis via intermetacarpal distance methods: an exploration of validity, reliability, and precision
To establish methods for assessing thumb palmar and radial abduction using intermetacarpal distance techniques in individuals with CMC1 osteoarthritis, and to evaluate the reliability and validity of these methods, highlighting their clinical significance.
Key Findings:
The IMD method for measuring thumb radial abduction showed acceptable agreement and excellent test-retest reliability, indicating its potential for clinical use.
No prior research on the test-retest reliability of IMD measurements for palmar abduction in CMC1 OA, suggesting a gap in the literature.
Using the mean of multiple trials improves reliability over a single measurement, which is crucial for accurate assessments.
Interpretation:
The study highlights the need for reliable measurement techniques for thumb abduction in CMC1 OA, suggesting that the IMD method may be a viable option compared to traditional methods.
Limitations:
Exclusion criteria may limit generalizability to broader CMC1 OA populations, potentially affecting the applicability of findings.
Potential measurement errors due to variability in MCP joint size and participant selection biases.
Conclusion:
Establishing reliable measurement methods for thumb abduction is crucial for assessing functional ability in individuals with CMC1 OA, with implications for improving patient care and guiding future research.
