Summary

The Reaching Performance Scale for Stroke (RPSS) is a responsive tool for measuring upper limb motor improvement in stroke survivors. It accurately captures changes across different stroke stages, aiding in comprehensive patient assessment.

Area of Science:

Neurorehabilitation
Motor Recovery Assessment
Clinical Measurement Validation

Background:

Stroke significantly impairs upper limb function, necessitating reliable assessment tools.
Existing measures may not fully capture motor compensations during recovery.
The Reaching Performance Scale for Stroke (RPSS) is a potential tool for evaluating upper limb function post-stroke.

Purpose of the Study:

To estimate the internal and external responsiveness of the Reaching Performance Scale for Stroke (RPSS).
To evaluate the RPSS's ability to detect changes in upper limb motor function in individuals with stroke.
To assess the RPSS across different stages of stroke recovery.

Main Methods:

Retrospective analysis of data from 4 randomized controlled trials involving 567 participants.
Virtual reality upper limb rehabilitation interventions were used.
Responsiveness was quantified using effect sizes (internal) and orthogonal regressions with the Fugl-Meyer Assessment of the Upper Extremity (FMA-UE) (external).

Main Results:

The RPSS demonstrated high internal responsiveness across acute, subacute, and chronic stroke stages.
External responsiveness showed moderate positive correlations between RPSS and FMA-UE scores (0.6
Area Under the Curve (AUC) values were acceptable (0.65-0.8) for detecting clinically important changes.

Conclusions:

The RPSS is a responsive measure, complementing its reliability and validity.
RPSS scores, alongside FMA-UE, provide a comprehensive assessment of upper limb motor improvement post-stroke.
The scale aids in characterizing motor compensations and recovery in stroke patients.
