Purpose:
The aim of this study is to investigate the validity and reliability of the Selective Control of Upper Extremity Scale (SCUES) in patients with stroke.
Materials And Methods:
Forty-two patients with stroke aged 18-75 years, were included in the study. Patients were video-recorded while SCUES was administered. The videos were scored to determine the intrarater and inter-rater reliability. Fugl Meyer Assessment of Upper Extremity (FMA-UE), Box and Block test (BBT) and Brunnstrom Stages of Motor Recovery were measured to evaluate validity of SCUES. Spearman correlation analysis was used to assess the validity of SCUES. Intraclass correlation coefficient (ICC), Kappa (κ) and weighted Kappa (κw) were calculated to determine intrarater and inter-rater reliability.
Results:
There were significant positive high correlations between SCUES and FMA-UE and BBT and Brunnstrom upper extremity proximal and distal values (rho = 0.944, p = 0.01; rho = 0,875, p = 0.01; rho = 0.84, p = 0.01, rho = 0.82, p = 0.01; respectively) showing validity of SCUES. The ICC value of inter-rater reliability of SCUES was 0,99 (%95 CI: 0,989-0,997, p = 0,001) showing excellent reliability. κ and κ w values for inter-rater and intrarater reliability of individual SCUES items were above 0.7 indicating excellent reliability. ICC of SCUES and FMA-UE indicated excellent intrarater reliability (ICC = 0,99; %95 CI: 0,989-0,997, p = 0,001; ICC = 0.943; %95 CI: 0.9-0.97, p = 0,0001, consecutively).
Conclusions:
SCUES showed similar validity and reliability with FMA-UE and SCUES can be used in the evaluation of upper extremity selective motor control in patients with stroke.
