Objective:
To investigate the concurrent validity of the KHMS with the FMA-UE.
Design:
The FMA-UE and the KHMS were administered to 50 adults with stroke to evaluate their concurrent validity.
Setting:
Three tertiary rehabilitation hospitals.
Participants:
Participants were aged ≥18 years, receiving stroke or rehabilitation services from a participating hospital, and had a confirmed diagnosis of stroke (ischemic or hemorrhagic) with upper limb involvement. Fifty patients were recruited to the study (20 women, 30 men, N=50) with a mean age of 71 (SD 13.4, range 35-90) years. Time since stroke varied from 2 days to 187 months, with a median of 0.8 months.
Interventions:
Not applicable.
Main Outcome Measures:
Concurrent validity of the KHMS with the FMA-UE.
Results:
A correlation of r=0.948 was found between the 2 scales (P=.0001). Moderate floor effects were noted in our sample (16%); however, significant ceiling effects were recorded (44%).
Conclusion:
The KHMS demonstrated a statistically strong correlation with the FMA-UE and holds promise for use, particularly in the clinical setting, to evaluate upper limb motor impairment after stroke.
