摘要 |
Background: Although the effects of robot-assisted arm training after
stroke are promising, the relative effects of unilateral (URT) vs. bilateral
(BRT) robot-assisted arm training remain uncertain. This study compared the
effects of URT vs. BRT on upper extremity (UE) control, trunk compensation,
and function in patients with chronic stroke. Method: This was a single-blinded, randomized controlled trial. The
intervention was implemented at 4 hospitals. Fifty-three patients with stroke
were randomly assigned to URT, BRT, or control treatment (CT). Each group
received UE training for 90 to 105 min/day, 5 days/week, for 4 weeks. The
kinematic variables for arm motor control and trunk compensation included
normalized movement time, normalized movement units, and the arm-trunk
contribution slope in unilateral and bilateral tasks. Motor function and
daily function were measured by the Wolf Motor Function Test (WMFT), Motor
Activity Log (MAL), and ABILHAND Questionnaire. Results: The BRT and CT groups elicited significantly larger slope
values (i.e., less trunk compensation) at the start of bilateral reaching
than the URT group. URT led to significantly better effects on WMFT-Time than
BRT. Differences in arm control kinematics and performance on the MAL and
ABILHAND among the 3 groups were not significant. Conclusions: BRT and URT resulted in differential improvements in
specific UE/trunk performance in patients with stroke. BRT elicited larger
benefits than URT on reducing compensatory trunk movements at the beginning
of reaching. In contrast, URT produced better improvements in UE temporal
efficiency. These relative effects on movement kinematics, however, did not
translate into differential benefits in daily functions. |
