Abstract
|
|
|
Purpose : We studied the correlation between reference voluntary contraction (% RVC) of vastus lateralis (VL) and vastus medialis (VM), Berg balance scale (BBS), and timed-up & go (TUG) test.
Methods : We recruited 30 stroke patients from a rehabilitation center at a hospital.? All subjects could walk with or without an assisting device. Subjects were evaluated with % RVC of VL and VM, BBS, and TUG. The data were analyzed using a Pearson correlation coefficient.
Results : The % RVC of VL and VM and BBS (p<0.01) showed a significant positive correlation. TUG negatively
correlated with % RVC of VL and VM and BBS (p<0.01).
Conclusion : Lower extremity muscle activity increases balance and walking ability. We recommend the implementation of lower extremity strength exercises in the rehabilitation of stroke patient.
