Summary
A new smartphone method reliably measures finger range of motion (ROM), offering a convenient alternative to traditional goniometers. This digital approach significantly reduces measurement time while maintaining high accuracy for finger joint assessments.
Area of Science:
- Orthopedics
- Biomedical Engineering
- Rehabilitation Medicine
Background:
- Traditional goniometers are standard for finger range of motion (ROM) measurement.
- Current methods can be complex and time-consuming for clinicians.
Purpose of the Study:
- To develop and validate a novel smartphone-based method for measuring finger ROM.
- To assess the reliability and convenience of the smartphone method compared to conventional goniometry.
Main Methods:
- Finger ROM was measured in 1007 joints using both a smartphone application and a standard goniometer.
- Intraclass correlation coefficient (ICC) was used to analyze the reliability of the smartphone method.
- Measurement time per joint was recorded for both methods.
Main Results:
- The smartphone method demonstrated high reliability, with an ICC score of 0.927.
- Average measurement time per joint was 49% lower using the smartphone compared to the goniometer.
- The smartphone method showed comparable reliability to the conventional goniometer.
Conclusions:
- Smartphone-based finger ROM measurement is a reliable and convenient alternative to traditional goniometry.
- This innovative method offers significant time-saving benefits for clinical practice.
- The study validates the use of smartphones for accurate joint range of motion assessment.
