Summary
Stroke survivors exhibit bilateral ankle proprioception deficits, impacting balance. The Active Movement Extent Discrimination Apparatus (AMEDA) reliably assesses these deficits on both affected and unaffected sides.
Area of Science:
- Neurorehabilitation
- Biomechanics
- Motor Control
Background:
- Proprioception deficits are common in stroke survivors.
- Ankle proprioception is crucial for balance post-stroke.
- Previous evaluation methods for ankle proprioception after stroke were insufficient.
Purpose of the Study:
- To validate the Active Movement Extent Discrimination Apparatus (AMEDA) for assessing ankle proprioceptive acuity in stroke survivors.
- To investigate the presence of bilateral ankle proprioception deficits in stroke survivors.
Main Methods:
- Assessed bilateral ankle proprioception in 20 stroke survivors and 20 healthy controls using AMEDA.
- Evaluated test-retest reliability with the intraclass correlation coefficient (ICC).
Main Results:
- AMEDA demonstrated good reliability (ICC 0.713–0.74) for both affected and unaffected sides.
- Stroke survivors showed significant ankle proprioception deficits compared to controls (p=0.045).
- No significant difference in proprioception acuity was found between affected and unaffected sides in stroke survivors.
Conclusions:
- Stroke survivors present with bilateral ankle proprioceptive deficits, necessitating evaluation of both sides.
- The AMEDA is a reliable tool for assessing bilateral ankle proprioceptive acuity in stroke survivors.
- Findings support the development of targeted sensorimotor rehabilitation strategies.
