Abstract:
Objective To investigate the effects of lower limb training at different intensities on the recovery of walking function after stroke.Methods Thirty-six stroke patients were randomly divided into a 40-minutes of training group,an 80-minutes of training group and a 120-minutes of training group.Because of three missing followup cases,the final numbers of cases were 12,11 and 10 cases respectively.All of the patients received lower limb training based on regular rehabilitation therapy,but at the three different intensities:40 minutes,80 minutes or 120 minutes a day,five days per week,for 4 weeks.Walking function was assessed using the Holden functional ambulation categories (FACs) and the Fugl-Meyer assessment (FMA).These were carried out before treatment,and after two and four weeks of treatment.Results Before treatment,the average FACs of the three groups were (1.83 ±0.94),(1.73 ± 1.01) and (1.80 ± 1.03) respectively.Their average FMA scores were (19.17 ±5.52),(23.00±4.71) and (19.40 ±7.90).After two weeks of treatment,the average FAC in the 120-minutes training group was (3.30 ± 0.48),significantly higher than in the 40-minutes training group.After four weeks the average FACs in the 40-minutes,80-minutes and 120-minutes training groups were (2.67 ± 0.65),(3.18 ± 0.60) and (3.80 ±0.42) respectively.The differences between the 120-minutes group and the 80-minutes group as well as between the 80-minutes group and the 40-minutes training group were statistically significant.The average FMA scores of the three groups after four weeks were (25.08±4.46),(28.64±3.56) and (25.90±5.19) respectively.All the differences were significant compared with pre-treatment.There were no significant differences in FMA scores among the three groups after two weeks or four weeks of treatment.Before treatment,the proportion of patients able to walk independently in the 40-minutes,80-minutes and 120-minutes training groups were 16.7％,18.2％ and 20.0％.After two weeks the proportions had risen to 33.3％,36.4％ and 100％ respectively,so the results in the 120-minutes training group were significantly better.After four weeks of treatment the proportions of the three groups were 58.3％,90.9％ and 100％.All these improvements were significant compared with pre-treatment,but when compared with the 80-minutes training group,neither of the others showed a significant difference.Conclusions Intensive training can accelerate the recovery of walking function of patients after stroke and promote their ability to participate in daily activities.
