OBJECTIVE: To examine the concurrent and predictive validity of measurements of
kinematic variables during reaching tasks with and without a trunk constraint in
individuals with stroke. DESIGN: Randomized controlled trials. SETTINGS:
Hospitals and a laboratory. PARTICIPANTS: Individuals with stroke (N=95) enrolled
in previous and ongoing clinical trials. INTERVENTIONS:
Upper limb training
protocols were 90 to 120 minutes of intervention every weekday for 3 to 4 weeks.
MAIN OUTCOME MEASURES: Functional capacity was assessed using the Action Research
Arm Test and motor impairment using the Fugl-Meyer Assessment for the Upper
Extremity. Movement kinematics were measured during a reaching task with and
without a trunk constraint. We derived 5 endpoint control variables and 3 joint
recruitment variables for estimating concurrent and predictive validity. RESULTS:
The adjusted R(2) values for the constraint tasks ranged from .24 to .38 and for
the unconstraint tasks from .29 to .40. Movement time was the most prominent
kinematic variable for the Fugl-Meyer Assessment for the Upper Extremity before
and after the intervention (P<.05). For the Action Research Arm Test, movement
time and endpoint displacement were the most significant variables before and
after the intervention, respectively (P<.05). CONCLUSIONS: Measuring kinematic
performance during an unconstrained task is appropriate and possibly sufficient
to represent motor impairment and functional capacity of individuals with stroke.
Movement time is the dominant variable associated with motor impairment and
functional capacity, and endpoint displacement is unique in reflecting functional
capacity of individuals with stroke.
