Functional neuromuscular stimulation (FNS) has been demonstrated to restore purposeful movement to muscles paralyzed by spinal cord injury (SCI). It is hoped that this technique will ultimately improve rehabilitation by enabling skilled activities for paraplegics (e.g., walking) and quadriplegics (e.g., feeding oneself) to be accomplished regularly with safety and reliability. It is also expected that FNS exercise programs will lead to higher levels of health and fitness for SCI individuals. However, high fatigability of electrically stimulated paralyzed muscles may severely limit FNS applications. This fatigability is related to numerous factors, including the deteriorated condition of the paralyzed muscles and cardiopulmonary system, the nonphysiologic way in which these muscles are activated with FNS, and the probability that organ system adjustments that normally accompany voluntary exercise do not occur to the same extent with this peripherally induced exercise. More research is necessary to determine the mechanisms of fatigue for FNS exercise so that methods could be devised to increase resistance to fatigue. In addition, more research is necessary to substantiate the potential health and fitness benefits that have been stated for FNS exercise training.
功能性神经肌肉刺激（FNS）已被证明能使因脊髓损伤（SCI）而瘫痪的肌肉恢复有目的的运动。人们希望这项技术最终能通过让截瘫患者（如行走）和四肢瘫痪患者（如自我进食）安全可靠地定期完成熟练活动来改善康复情况。人们还期望FNS锻炼计划能使SCI患者达到更高的健康和体能水平。然而，电刺激瘫痪肌肉的高疲劳性可能会严重限制FNS的应用。这种疲劳性与多种因素有关，包括瘫痪肌肉和心肺系统的恶化状况、FNS激活这些肌肉的非生理方式，以及通常伴随自愿运动的器官系统调整在这种外周诱导运动中不会以相同程度发生的可能性。需要更多研究来确定FNS锻炼的疲劳机制，以便能设计出增加抗疲劳能力的方法。此外，需要更多研究来证实FNS锻炼训练所宣称的潜在健康和体能益处。
