Abstract
Aim: To use three-dimensional motion analysis during walking to:
1. Define upper limb associated reaction kinematics
2. Devise composite score outcome measures to quantify associated reactions
Design: Cross-sectional observational study.
Method: Forty-two participants with a brain injury and hemiplegic upper limb associated reaction during walking and 36 healthy controls underwent three-dimensional motion analysis. The mean, standard deviation, peak and total joint range-of-motion were calculated for each axis across the gait cycle. Associated reaction kinematics were evaluated first on a group level with analysis of covariance quantifying the between-group differences. Second, associated reaction kinematics were evaluated on an individual participant level with calculation of the percentage of participants with brain injury classified as abnormal for each outcome variable. Abnormality was defined as ±1.96 standard deviation of the healthy control mean. Composite score outcome measures were devised for the for the affected upper limb to quantify the associated reaction kinematic abnormality with evaluation of their validity, test–retest reliability, and responsiveness.
Results: Significant between-group differences existed for all elbow and shoulder abduction outcome variables (p < 0.01), most shoulder flexion variables, forearm rotation standard deviation and range-of-motion and wrist flexion range-of-motion. Associated reactions most frequently affected elbow flexion and shoulder abduction axes. The elbow was most prevalently affected (38/42, 90%), but abnormality at the shoulder (32/42, 76%), forearm (20/42, 48%) and wrist joints (10/42, 24%) were common. Very-strong correlations existed between the composite scores r > 0.98). All scores had very-strong test–retest reliability (ICCs > 0.81) and provided different information regarding the effort-dependent change in associated reactions.
Conclusion: All upper-limb joints are commonly implicated in associated reactions and therefore warrant inclusion in clinical assessment. Composite scores combined kinematic data to yield a summary score of associated reaction abnormality. Composite scores comprehensively assessed the whole upper-limb associated reaction, accurately classified abnormality, and quantified severity with very-strong clinimetrics.
