Summary
Grip force (GF) control assessment in cervical myelopathy (CM) patients shows promise. Measuring individual finger GF offers a new indicator for upper extremity symptom severity in CM.
Area of Science:
- Neurology
- Biomechanics
- Rehabilitation Medicine
Background:
- Cervical myelopathy (CM) significantly impacts upper extremity function.
- Objective evaluation of grip strength is crucial for assessing CM severity.
- Current clinical tests may not fully capture functional deficits.
Purpose of the Study:
- To objectively evaluate grip force (GF) control during a holding task in individuals with CM.
- To correlate GF measurements with established clinical assessments.
- To determine the utility of GF control in predicting CM symptom severity.
Main Methods:
- Cross-sectional study involving 26 individuals with CM (52 hands).
- Participants performed a pulp pinch grip-and-lift task.
- Individual finger GF was monitored during object holding; correlations with clinical tests were analyzed.
Main Results:
- Thumb GF negatively correlated with the 10-s test; index finger GF positively correlated with cutaneous pressure threshold.
- A regression model incorporating GF showed improved predictive value for upper extremity symptom severity compared to conventional tests.
Conclusions:
- Individual finger GF control assessment is a potential new indicator for upper extremity symptom severity in CM.
- GF measurement offers an objective method to complement existing clinical evaluations.
- Further research can validate GF control as a standard clinical metric for CM.
