30 individuals of both genders; Age between 18 and 60 years; CLBP ≥ 3 months: BMI ≤ 34; Pain ntensity ≥ 3; Modified Oswestry Disability Questionnaire ≥ 20. |
Nonspecific NMES:
- Applied to lumbar paravertebral muscles bilaterally via 2 self-adhesive electrodes;
Stabilization exercise protocol:
- Performed under the supervision of a physical therapist;
- Consisting of 13 abdominal strengthening exercises subdivided into: 5 strengthening exercises without weight bearing. 5 exercises with weight bearing and 3 exercises in the 4 supports position;
- 20 to 30 repetitions of each exercise were performed, with the times of bearing varying from 4 to 10 sec;
- Total protocol duration: 20 min;
- Frequency: 2 times a week, for 6 weeks, totaling 12 sessions.
|
- Exercise Group (EXG): performed a stabilization exercise protocol, n=156.
- Exercise + Electrostimulation Group (EXNMESG): underwent exercise protocol and NMES, n=15.

|
Increase in muscle endurance between EV 1 and EV 2 in RCG; increase between RCG versus CG in EV 3.
No significant difference between groups and between evaluations (at all time points).

Brazil |
30 sedentary women; Age between 18 and 35 years; Nonspecific CLBP ≥ 4 on VAS. |
Nonspecific NMES of 2500 Hz:
- NMES was applied synchronously with the CORE exercises (exercise isometrics were performed when current was On, and rest when the current was Off);
- The electrodes were positioned in the region covering gluteus maximus and medius, rectus abdominis, and transversus abdominis bilaterally.
Exercise protocol for CORE strengthening:
- Performed under the supervision of the researchers;
- Composed of static postures sustained in isometrics;
- In each session the participants performed 4 sets (postures) of 10 repetitions sustained for 10 seconds each, with an interval of 20 seconds between repetitions and 60 seconds between sets;
- Total protocol duration: 25 min;
- Frequency: 3x/week for 4 weeks, totaling 12 sessions.
|
- CORE Group (CG): underwent CORE strengthening protocol, n=10.
- Electrostimulation group (EG): underwent treatment with N, n=10.
- Electrostimulation + CORE Group (ECG): underwent treatment with NMES synchronized with voluntary contraction during CORE strengthening exercises, n=10.

CORE muscles stabilization strength (average in sec): trunk static endurance test, Sorenson's test, side bridge test and prone instability test. |
- Pre-treatment (EV 1).
- After 12 sessions (EV 2).
- Six months after end of treatment (EV 3).
|
Significant increase between EV 2 and EV 3 versus EV 1 in ECG in all tests; significant increase between EV 2 versus EV 1 in EG in Sorenson's test; and significant difference between ECG versus CG and EG in all tests. |
