Wrist Proprioception in Adults with and without Subacute Stroke.

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Motor Control

Background:

• Proprioception is essential for motor control and daily function.
• Early proprioception deficits after stroke are understudied.
• Understanding these deficits is crucial for effective stroke rehabilitation.

Purpose of the Study:

• To investigate wrist proprioception in subacute stroke patients.
• To compare proprioception between stroke survivors and healthy controls.
• To determine if proprioception deficits correlate with motor or cognitive function.

Main Methods:

• Utilized the Wrist Position Sense Test (WPST) to quantify wrist proprioception.
• Assessed stroke patients (n=18) and healthy controls (n=19).
• Performed serial testing on a subset of patients (n=12).

Main Results:

• Stroke patients exhibited significantly higher WPST error in the more-affected wrist compared to controls and their less-affected wrist.
• Abnormal wrist proprioception was prevalent in 88.2% of the more-affected wrists and 72.2% of the less-affected wrists.
• Proprioception deficits were bilateral and did not improve significantly over time.

Conclusions:

• Wrist proprioception deficits are common, bilateral, and persistent in the subacute phase post-stroke.
• These deficits are not directly explained by age, motor, or cognitive impairments.
• Targeting proprioception may be a vital component of stroke recovery interventions.
