目的 探讨弹力带抗阻训练对脑卒中下肢运动功能障碍患者肌力水平、运动耐力的影响。方法 选择2021-06—2022-12在南京市江宁医院接受治疗的80例脑卒中下肢运动功能障碍患者进行研究,采用随机数表法分为试验组(n=40)和对照组(n=40)。对照组给常规运动指导治疗,试验组加用弹力带抗阻训练治疗。比较2组临床疗效、肌力水平、峰值摄氧量(VO_(2)peak)、无氧阈值(AT)、6 min步行距离、步态参数及Barthel指数、平衡功能评分变化情况。结果 治疗后,试验组总有效率85%,高于对照组的65%,差异有统计学意义(P<0.05);试验组下肢肌力评分低于对照组[(1.40±0.23)分比(1.98±0.63)分],Fugl Meyer运动量表评分高于对照组[(29.87±3.58)分比(24.15±3.74)分],差异均有统计学意义(P<0.05);试验组VO_(2)peak、AT及6 min步行距离分别为(20.42±1.71)m L/(min·kg)、(13.89±1.01)mL/(min·kg)、(140.56±23.78)m,均高于对照组的(18.46±1.23)m L/(min·kg)、(13.02±1.21)mL/(min·kg)、(116.58±29.61)m,差异均有统计学意义(P<0.05);试验组步长、步速、步频及单支撑相水平分别为(36.87±4.71)cm、(57.78±7.23)cm/s、(69.31±5.41)step/s、(31.05±3.01)%,均高于对照组的(31.52±3.67)cm、(52.84±6.09)cm/s、(63.05±6.08)step/s、(27.21±3.08)%,差异均有统计学意义(P<0.05);试验组Barthel指数、平衡功能评分分别为(78.61±5.61)分、(41.15±2.31)分,均高于对照组的(67.59±6.13)分、(32.56±5.47)分,差异均有统计学意义(P<0.05)。结论 在脑卒中下肢运动功能障碍患者中弹力带抗阻训练治疗有较好的效果,可有效改善肌力水平、运动耐力水平。

Objective To investigate the effect of resistance training with elastic band on muscle strength and exercise endurance of stroke patients with lower limb motor dysfunction.Methods Eighty stroke patients with lower limb motor dysfunction treated in Nanjing Jiangning Hospital from June 2021 to December 2022 were selected,and were divided into experimental group(n=40)and control group(n=40)by random number table method.The control group was treated by routine exercise guidance,and the experimental group was treated by elastic band resistance training.The clinical effect,muscle strength level,peak oxygen uptake(VO_(2)peak),anaerobic threshold(AT),6 minutes walking distance,gait parameters,Barthel index,and balance function score were compared between the two groups.Results After treatment,the total effective rate of the experimental group was 85%,which was higher than that of the control group(65%),and the difference was statistically significant(P<0.05).Lower limb muscle strength score of experimental groups was lower than that of control group(1.40±0.23vs 1.98±0.63),and FMMS score was higher than that of control group(29.87±3.58 vs 24.15±3.74),the differences were statistically significant(P<0.05).The VO_(2)peak,AT and 6 minutes walking distance of the experimental groups was(20.42±1.71)m L/(min·kg),(13.89±1.01)m L/(min·kg),(140.56±23.78)m,respectively,which was higher than that of control group((18.46±1.23)m L/(min·kg),(13.02±1.21)m L/(min·kg),(116.58±29.61)m,respectively),and the differences were statistically significant(P<0.05).The step length,step speed,step frequency and single support phase level of experimental groups was(36.87±4.71)cm,(57.78±7.23)cm/s,(69.31±5.41)step/s,(31.05±3.01)%,respectively,which was higher than the control group((31.52±3.67)cm,(52.84±6.09)cm/s,(63.05±6.08)step/s,(27.21±3.08)%,respectively),the differences were statistically significant(P<0.05).Barthel index and balance function score of the experimental group were(78.61±5.61)points and(41.15±2.31)points,respectively,which were higher than those of control group((67.59±6.13)points and(32.56±5.47)points,respectively),and the differences were statistically significant(P<0.05).Conclusion In stroke patients with lower limb motor dysfunction,elastic band resistance training has a good effect,which can effectively improve the level of muscle strength and exercise endurance.
