Background.
Kinematic
analysis is commonly used to objectively measure upper extremity movement performance
after stroke. However, the concurrent and predictive validity of arm-trunk kinematics during
reaching within and beyond arm’s length has not been studied. Objective.
The study
aimed to estimate the concurrent validity of kinematic measures before and
after treatment and the predictive validity for reaching within and beyond
arm’s length after stroke. Design. This was a secondary analysis
study. Methods. Ninety-seven participants with
stroke (aged 55.9 ± 10.9 years) received intensive treatment every weekday
for 3 to 4 weeks. Kinematic reaching tasks and the Wolf Motor Function Test
(WMFT) were evaluated before and after treatment. The validity of the
kinematic measures was estimated against WMFT scores. Results. Of the 8 kinematic variables that were
measured, index movement time before treatment (R2 = .227-.362) and
the trunk movement time and displacement after treatment (R2 =
.095-.346) had the strongest association with WMFT for both reaching
distances. The trunk movement time and displacement before treatment
explained 6.9% to 14.9% of variances in WMFT after treatment. Kinematic
variables explained 6.9% to 49.3% of variances in WMFT during a task within
arm’s length and 9.4% to 38.7% beyond arm’s length. Limitations.
The
results cannot be attributed to the effects of any specific treatment. Conclusions.
Different
kinematic variables might partially reflect motor function before and after
treatment to a limited degree. Although the predictive validity is modest,
trunk movement might be considered one of the potential prognostic
determinants of motor function after treatment. A reaching task within arm’s
length might be
more suitable to obtain kinematic performance for describing motor function
than one that is beyond arm’s length. |
