To evaluate impact of first therapy session, containing functional electrical stimulation (FES) and therapeutic exercises (TE) on erector spinae (ES) and rectus abdominis (RA) force generation in persons with spinal cord injury (SCI).
Five men with SCI were divided in two groups - FES+TE received concurrent FES on ES and RA and TE, TE only TE. Participants performed exercises for improving sitting balance and posture. Muscles' electrical activity was evaluated by electromyography; amplitude (AEMG) and median frequency (MF) were used for analysis.
AEMG of ES left (L) increased 292.9% (g=-0.92), right (R) 175% (g=-1.01), RA L 314.3% (g=-0,81, P<0.05), R 266.7% (g=-0.08) in FES+TE. AEMG of ES L increased 47.6% (g=-0.46), R 96.4% (g=-0.95); RA L 7.1% (g=-0.97), but R decreased 6.7% (g=0.12) in TE. MF of ES L increased 108.5% (g=-0.74), R 184% (g=-1.25); RA L 886.7% (g=3-05, P<0.05), R 817.6% (g=-2.55, P<0.05) in FES+TE. MF of ES L increased 95.2% (g=-1.02), R 161.4% (g=-1.64); RA L 3,2% (g=-0.06), R 30.8% (g=-0.46) in TE.
In SCI persons, single session exercises and concurrent functional electrical stimulation may be more effective on muscles` force generation than only exercises. However, replication of the results is needed before clinical implementation.
评估第一治疗疗程(包含功能性电刺激(FES)和治疗性运动)对脊髓损伤(SCI)患者竖脊肌(ES)和腹直肌(RA)产生的力的影响。
将 5 名男性 SCI 患者分为两组:FES+TE 组同时接受 ES 和 RA 的 FES 和治疗性运动,TE 组仅接受治疗性运动。参与者进行了改善坐姿平衡和姿势的运动。通过肌电图评估肌肉的电活动;使用振幅(AEMG)和中值频率(MF)进行分析。
FES+TE 组中 ES 左侧(L)的 AEMG 增加了 292.9%(g=-0.92),右侧(R)增加了 175%(g=-1.01),RA L 增加了 314.3%(g=-0.81,P<0.05),R 增加了 266.7%(g=-0.08)。ES L 的 AEMG 增加了 47.6%(g=-0.46),R 增加了 96.4%(g=-0.95);RA L 增加了 7.1%(g=-0.97),但 R 减少了 6.7%(g=0.12)。FES+TE 组中 ES L 的 MF 增加了 108.5%(g=-0.74),R 增加了 184%(g=-1.25);RA L 增加了 886.7%(g=3-05,P<0.05),R 增加了 817.6%(g=-2.55,P<0.05)。ES L 的 MF 增加了 95.2%(g=-1.02),R 增加了 161.4%(g=-1.64);RA L 增加了 3.2%(g=-0.06),R 增加了 30.8%(g=-0.46)。
在 SCI 患者中,单次疗程的运动和同时进行的功能性电刺激可能比仅进行运动更能有效增加肌肉的力量产生。然而,在临床实施之前,需要对结果进行复制。
