OBJECTIVE: To compare the immediate effects of conventional treadmill gait and
guidance tubing gait (GTG) on electromyographic neuromuscular imbalance and knee
joint kinematics in hemiparetic gait. DESIGN: Case-control study. SETTING:
University medical center. PARTICIPANTS: Participants (N=33; 19 men, 14 women)
were patients with hemiparetic stroke (n=18 [experimental]; mean age +/- SD,
39.2+/-16.8y) and healthy controls (n=15; mean age +/- SD, 26.3+/-2.6y).
INTERVENTIONS: The GTG was provided for approximately 30 minutes and involved
application of an assistive guidance force using the tubing, specifically to
improve knee joint stabilization during midstance and increase knee joint flexion
during midswing phase. MAIN OUTCOME MEASURES: Clinical tests included the Korean
Mini-Mental State Examination, Modified Ashworth Scale, Berg Balance Scale,
manual muscle test, and knee joint range of motion and sensory tests. Knee joint
muscle electromyographic and kinematic analyses were determined at pretest and
posttest. RESULTS: After the intervention, the experimental group showed
significantly greater improvements in balanced quadriceps and hamstring
electromyographic coactivation and knee joint kinematics relative to the control
group (P=.005). The GTG intervention decreased overactive hamstring activity
(P=.018) and reciprocally increased quadriceps activity (P<.001). The knee joint
kinematic analysis showed significant changes in the hemiparetic stroke group
(P=.004). CONCLUSIONS:
This study demonstrates the effectiveness of the tubing
gait condition to restore knee joint muscle imbalance and kinematics in
individuals with hemiparetic stroke who present with an abnormal hyperextension
knee gait.
