Quantitative clinical assessment of wrist proprioception with stroke survivors

TL;DR

This study shows how clinicians can use a wrist test to detect proprioceptive impairment in stroke survivors, helping improve diagnosis and treatment.

Contribution

The study establishes a new criterion for wrist proprioception impairment and validates a shorter version of the test for clinical use.

Findings

Proprioceptive impairment was common in the contralesional wrist (66%) and present in the ipsilesional wrist (21%).

A new criterion of abnormality was set at 11.10 average error with high sensitivity and specificity for the brief test version.

Abstract

The aims of this study were to characterise proprioceptive impairment in individuals after stroke using the Wrist Position Sense Test (WPST) in a relatively large pooled sample, to re-establish the criterion of abnormality of the WPST, and to determine the sensitivity and specificity of a briefer test version for use in clinical settings.

Cross-sectional observation study with pooling of data across studies.

Rehabilitation or outpatient settings.

Stroke survivors (n = 205) and neurologically healthy controls (n = 93) were assessed at baseline.

Wrist proprioception assessed using the WPST.

Baseline data from stroke survivors and healthy controls assessed on the WPST was extracted from six studies. Raw data were pooled and analysed to determine an updated criterion of impairment and ability of a brief 10-trial version to detect proprioceptive impairment.

Proprioceptive impairment was common for the contralesional wrist (66%) and present in the ipsilesional wrist (21%). The new criterion of abnormality was established as 11.10 average error. High sensitivity and specificity were found for the brief 10-trial version, with 85.3% sensitivity and 95.7% specificity.

Clinicians can quantitatively and confidently identify proprioceptive impairment in the upper limb after stroke using either the original or brief version of the WPST. Routine use of this quantitative, standardised clinical assessment can contribute to improved identification, monitoring, and access to targeted intervention for proprioceptive impairment following stroke.
