Abstract
Aim: To compare the accuracy of subjective upper-limb associated reaction rating during walking using the International Classification of Functioning, Disability and Health Framework Qualifiers Scale compared to kinematics from criterion-reference three-dimensional motion analysis.
Design: Cross-sectional observational study.
Method: Forty-one participants with a brain injury and an upper-limb associated reaction during walking underwent three-dimensional motion analysis at their self-selected walking speed with kinematic deviation scores quantifying abnormality in the whole upper limb and each joint axis. Three experienced neurological physiotherapists viewed video recordings of the participants’ walking trials and applied the Qualifiers Scale to subjectively rate the global associated reaction severity and severity at each upper limb joint on a 5-point scale. The comparative accuracy was calculated via quantifying relationships (Fisher’s exact test), percentage agreement, sensitivity, and specificity.
Results: The Qualifiers Scale had limited accuracy compared to three-dimensional motion analysis upper limb assessment. The wrist severity score was the only outcome demonstrating a significant relationship to the corresponding kinematic deviation score (p < 0.05). Four out of seven outcomes had ≤ 58% agreement in abnormality classification. None of the outcomes had high sensitivity and specificity. The sensitivity was relatively low for all outcomes (0.32–0.73) and specificity relatively high (>0.80) for four of the seven outcomes.
Conclusion: The Qualifiers scale tended to under classify abnormality compared to three-dimensional motion analysis with false negatives likely. The Qualifiers scale cannot be confidently implemented in clinical practice. There appears to be a disconnect between 3DMA and subjective rating of ARs. Objective associated reaction assessment is required.
