Single-subject case (male, 33 years of age, T6 SCI AIS A).
To determine the effect of surface neuromuscular electrical stimulation (NMES) training conducted once weekly on improving fatigue resistance as well as regional and whole body composition in an individual with spinal cord injury (SCI).
Laboratory setting within a SCI Center.
Surface NMES resistance training (RT) of the paralyzed knee extensors was conducted once weekly for 12 weeks using ankle weights. Knee extensor fatigue index was determined by the number of repetitions (reps) achieved out of 30 reps. Total and regional body composition including percentage body fat (%BF), fat mass (FM), lean mass (LM) were conducted before the first session and one week after the last training session using whole-body dual-energy X-ray absorptiometry.
The participant had a compliance rate of 83% and he was able to lift 6 and 2 lbs on the right and left legs, respectively. Right knee extensors showed greater fatigue resistance compared to the left one. Leg LM increased by 6% accompanied with decrease in arm, trunk and total body LM by -4.7%, -13%, -5%, respectively. The %BF increased by 8%, 7.3%, 15.5%, 11.5% for arm, legs, trunk and total body.
Once weekly of NMES RT evokes local positive changes in leg LM without reciprocating the continuous loss in LM or gain in FM in other regions and total body. Training was effective in increasing strength as well as fatigue resistance of the trained knee extensors.
单病例研究（男性，33岁，T6脊髓损伤，美国脊髓损伤协会损伤分级A 级）。
确定每周进行一次的表面神经肌肉电刺激（NMES）训练对改善脊髓损伤（SCI）个体的抗疲劳能力以及局部和全身成分的影响。
SCI中心内的实验室环境。
使用踝部负重，每周对瘫痪的膝伸肌进行一次表面NMES抗阻训练（RT），共进行12周。通过30次重复动作中完成的重复次数来确定膝伸肌疲劳指数。在第一次训练前和最后一次训练后一周，使用全身双能X线吸收法测量全身和局部身体成分，包括体脂百分比（%BF）、脂肪量（FM）、去脂体重（LM）。
参与者的依从率为83%，其右腿和左腿分别能够举起6磅和2磅的重量。与左腿相比，右膝伸肌表现出更强的抗疲劳能力。腿部LM增加了6%，而手臂、躯干和全身的LM分别减少了-4.7%、-13%、-5%。手臂、腿部、躯干和全身的%BF分别增加了8%、7.3%、15.5%、11.5%。
每周一次的NMES RT可引起腿部LM的局部正向变化，而不会抵消其他部位和全身LM的持续减少或FM的增加。该训练在增强训练的膝伸肌力量和抗疲劳能力方面是有效的。
