OBJECTIVE: To explore the effectiveness of modified sit-to-stand training on
balance function in hemiplegic stroke patients. DESIGN: Randomized controlled trial. SETTING: Rehabilitation medical centre.
PARTICIPANTS: A total of 50
hemiplegic patients with stroke were randomly assigned to the control and
experimental groups (n = 25 for each group). INTERVENTIONS: Patients in the
control group received the sit-to-stand training with symmetrical foot position,
while patients in the experimental group were given the modified sit-to-stand
training in which the paretic foot placed posterior. Subjects in both groups
received 30 minutes of sit-to-stand training, five times a week, for four weeks.
MAIN OUTCOME MEASURES: The time and weight-bearing distribution during
sit-to-stand movement, the centre of pressure sway length during quiet standing,
the centre of pressure sway areas during dynamic standing and Berg Balance Scale
were assessed before and after completing the four-week sit-to-stand training.
RESULTS: Our data showed significant improvements in standing balance and the
sit-to-stand movement for two groups in the post-training compared with the
pre-training. After training, the rise time shortened more significantly in the
experimental group (mean change, 0.90 +/-0.25 seconds) than the control group
(mean change, 0.42 +/-0.18 seconds). Weight-bearing asymmetry showed
significantly greater improvement in the experimental group (mean change, 0.17
+/-0.10) than in the control group (mean change, 0.06 +/-0.05). Centre of
pressure sway length was significantly smaller in the experimental group (mean
change, 27.85 +/-10.58 cm) than in the control group (mean change, 21.95 +/-8.19
cm). Centre of pressure sway areas was significantly larger in the experimental
group (mean change, 84.24 +/-26.48 cm(2)) than in the control group (mean change,
67.74 +/-22.84 cm(2)) (P = 0.027). The Berg Balance Scale was significantly
higher in the experiment group (mean change, 8.4 +/-3.1) than the control group
(mean change, 5.8+/-2.8). CONCLUSIONS: A modified sit-to-stand training improves
the balance function in hemiplegic stroke patients.
