- FRR was calculated by dividing the maximal EMG amplitude during flexion by the minimum EMG amplitude at full flexion. The mean of the 3 trials performed was used to determine the FRR for each muscle for each subject.

简要总结
The purpose of this study is to evaluate the effect of a Pilates exercise program (PEP) on the flexo-relaxation ratio (FRR) of the erector spinae (ES) muscle during standing maximal trunk flexion/extension in women with chronic low-back pain (LBP). A secondary goal is to investigate the effect of PEP on full trunk flexion ROM (TFRoM), pain intensity and functional capacity and analyse their relationship with the FRR.
详细描述
Purpose: To evaluate the effect of a Pilates exercise program (PEP) on the flexo-relaxation ratio (FRR) of the erector spinae (ES) muscle during standing maximal trunk flexion/extension in women with chronic low-back pain (LBP). A secondary goal was to investigate the effect of PEP on full trunk flexion ROM (TFRoM), pain intensity and functional capacity and analyse their relationship with the FRR. Material and methods: Thirty women with chronic LPB were randomly assigned to either PEP (EG, n=15) or control group (CG=15). EG followed an 8-week PEP while no specific intervention was carried out on the controls. Before and after this period all variables were recorded.

结局指标
主要结局
FRR was calculated by dividing the maximal EMG amplitude during flexion by the minimum EMG amplitude at full flexion. The mean of the 3 trials performed was used to determine the FRR for each muscle for each subject.
时间窗: 2 months
A lower FRR indicated a greater state of muscle relaxation. Asymmetry in muscle activity between both (right and left) ES muscles was calculated as their mean difference in RMS in the three flexion-extension tasks. Asymmetry in the FRR was calculated as the absolute difference between FRR of the right and left ES muscles.
次要结局
- The version adapted to the Spanish population of the Low Back Outcome Score (LBOS) questionnaire was used to measure self-reported functional capacity.(2 months)
- A 10-cm Visual Analog Scale (VAS) was used to evaluate pain intensity(2 months)
- Full TFRoM was calculated as the average TFRoM from the three flexion-extension tasks.(2 months)
