Background And Aim:
The aims of this study were to investigate the psychometric property of the Comprehensive Coordination Scale (CCS) in people with stroke.
Design:
Cross-sectional design.
Setting:
University based neurorehabilitation laboratory.
Population:
Sixty-two people with stroke (33 men; mean ages=67.1±6.4 years; 8.8±4.9 years) and 31 healthy older adults (10 men, mean ages=65.9±4.2 years).
Methods:
CCS was conducted on the subjects, followed with ARAT, BBS, LOS, MoCA, and SF-12muscle strength test, Fugl-Meyer Assessment of Lower Extremity (FMA-LE) and Upper Extremity (FMA-UE), muscle strength, Montreal Cognitive Assessment (MoCA), Action Research Arm Test (ARAT), Berg Balance Scale (BBS), Limit of Stability (LOS) test and 12-Item Short Form Survey (SF12).
Results:
There was a significant difference (P<0.001) of CCS score between people with stroke (mean difference=48.0±13.5) and healthy older adults (mean difference=62.9±12.1). CCS showed excellent test-retest reliability (intraclass correlation coefficient (ICC)=0.953). The CCS-Total Score showed a significant positive correlation with the average muscle strength of affected side (dorsiflexors, plantarflexors, elbow flexor, and elbow extensor), FMA-UE score, FMA-LE Score, BBS Score, ARAT Score, and LOS (EE and ME) (r=0.387-0.857, P<0.007) in this study. The CCS-total score of 62.5 (sensitivity 83.9%; specificity of 83.9%; AUC=0.892, P<0.001) was shown to distinguish the walking performance between people with stroke and healthy older adults.
Conclusions:
The CCS is a reliable, valid and objective assessment tool for evaluating the motor coordination in people with stroke. The CCS exhibited good diagnostic power for distinguishing the coordination ability of individuals with stroke from that of healthy older adults.
Clinical Rehabilitation Impact:
Therefore, the CCS is recommended for use in clinical settings to provide a detailed and comprehensive assessment of motor coordination impairment in stroke survivors.
