Locomotor training (LT) enhances walking in individuals with spinal cord injuries (SCIs). We tested the acute effects of 4 days of LT using BWSTT combined with Robotic Locomotor therapy compared to BWSTT twice weekly.
Two non-ambulatory participants with an American Spinal Injury Association Impairment Scale (AIS) D. Both received LT for 2 weeks as a portion of their clinical inpatient rehabilitation program and both used wheelchairs as their primary method of mobility. Over a 2 week period, one participant received a total of 8 visits consisting of manual BWSTT (twice weekly) combined with Robotic locomotor therapy (twice weekly). The other participant preformed manual BWSTT (twice weekly) for a total of 4 visits. Resting energy expenditure, body composition, muscle strength, submaximal oxygen consumption (VO2) and blood lactate during LT were measured pre and post-training.
The average maximum voluntary contraction of both knee extensor muscle groups increased by 28-34% with associated reduction in spasticity to the BWSTT participant. Two week interventions resulted in a downward shift of the lactate concentrations for both participants, increase in resting energy expenditure and shift in substrate utilization.
A clinical paradigm of incorporating BWSTT with robotic locomotor therapy for 4 days/ week did not provide additional physiological benefits to skeletal muscle strength, spasticity or metabolic profile compared to twice weekly of LT using BWSTT.
运动训练（LT）可增强脊髓损伤（SCI）患者的步行能力。我们测试了 4 天 BWSTT 联合机器人运动疗法与每周 2 次 BWSTT 相比对急性的影响。
2 名非运动性参与者的美国脊髓损伤协会损伤量表（AIS）为 D 级。两人均接受 LT 治疗 2 周，作为其临床住院康复计划的一部分，且均使用轮椅作为主要移动方式。在 2 周内，一名参与者总共接受了 8 次访问，包括手动 BWSTT（每周 2 次）和机器人运动疗法（每周 2 次）。另一名参与者共接受了 4 次手动 BWSTT（每周 2 次）。在 LT 期间，测量了休息能量消耗、身体成分、肌肉力量、次最大耗氧量（VO2）和血液乳酸。
两名参与者的膝关节伸肌肌群的最大自主收缩平均增加了 28-34%，与 BWSTT 参与者的痉挛程度降低相关。两周的干预导致两名参与者的乳酸浓度下降，静息能量消耗增加，底物利用发生转移。
与每周 2 次 BWSTT 相比，每周 4 天结合 BWSTT 的机器人运动疗法的临床范式并没有为骨骼肌力量、痉挛或代谢特征提供额外的生理益处。
