Summary
In hemiplegic patients, increased foot spasticity correlates with greater foot supination. Reduced navicular drop and altered calcaneal position also indicate more supinated feet in these individuals.
Area of Science:
- Orthopedics
- Neurology
- Rehabilitation Medicine
Background:
- Hemiplegia, often resulting from stroke, frequently leads to motor impairments affecting the lower extremities.
- Structural foot deformities are common in hemiplegic individuals, impacting gait and balance.
- Understanding the factors contributing to these deformities is crucial for effective rehabilitation.
Purpose of the Study:
- To evaluate foot joint structural deformities in hemiplegic patients.
- To identify factors influencing foot deformities in hemiplegia.
Main Methods:
- Foot posture index (FPI) for foot shape assessment.
- Modified Ashworth scale for ankle joint rigidity.
- Navicular drop test for navicular change.
- Resting calcaneal stance position test for heel bone location.
Main Results:
- Hemiplegic patients exhibited varying FPI scores on paretic and non-paretic sides compared to controls.
- Increased spasticity was associated with a more supinated foot on the paretic side.
- Smaller navicular drop and greater calcaneal position changes correlated with increased foot supination.
Conclusions:
- Foot spasticity is a significant factor in developing supinated foot deformities in hemiplegic patients.
- Navicular height changes and calcaneal positioning are key indicators of foot supination severity.
- These findings can inform targeted interventions for managing foot deformities in hemiplegia.
