研究组 & 干预措施
Stabilization exercises
The stabilization exercises program will consist of exercises for the lower back and abdomen. These exercises include various types of abdominal bracing and bridging and side bridging. The exercises will be performed in supine, sidelying, and quadruped. It involves activation of muscles, dissociation of lumbar spine movement from extremities movement and endurance.
干预措施: Rehabilitation exercises (Other)
Stabilization exercises plus electrical stimulation
The neuromuscular electrical stimulation is a hand-size unit that has four plastic adhesive electrical conductors known as electrodes. These electrodes are going to be placed on the skin covering the lower back muscles. They will deliver an electric current that will generate muscle contraction that resembles normal muscle contraction. This treatment will be given in addition to the stabilization exercise program.

结局指标
主要结局
Tolerability of Electrical Stimulation (NMES)
时间窗: Participants were followed from baseline to 6 weeks
NMES tolerability was performed by asking each subject in the stab + NMES group to describe their subjective perception of both the intensity and discomfort of the NMES current using the descriptors listed in a table. The descriptors represent two distinct domains of adjectives: the sensory aspect of the perceived intensity of stimulation and the affective aspect of the perceived discomfort. Each aspect has 15 adjectives. Each subject was asked to describe the current using the descriptors listed for each aspect at baseline and at 6 weeks. To analyze the the subjects description of the current, the 15 descriptors of each aspect were divided into 3 zones (high, medium, low). The top 5 descriptors in each aspect were considered high, the middle 5 descriptors were considered medium, and the bottom descriptors were considered low. Descriptive statistics were used to compare the subjects description of each aspect at baseline and at 6 weeks follow-up.
Modified Oswestry Disability Questionnaire (MODQ)
时间窗: Baseline to 6 weeks (post-treatment) to 10 weeks (follow up).
The MODQ is a self-reported measure of disability consisting of 10 domains of functional activities related to low back pain. The domains include pain intensity, personal care, lifting, walking, standing, sitting, traveling, social life, employment/homemaking, and sleeping. Each domain is rated from 0 - 5. The total of all the domains range from 0 - 50. The scores can be multiplied by 2 to get a percentage of functional disability. The higher the percentage the higher the disability.
次要结局
- Fear-avoidance Behavior Questionnaire(Baseline to 6 weeks (post-treatment))
- Patient Satisfaction Survey(only post-treatment at 6 weeks)
- Numeric Pain Rating Scale (NPRS)(Baseline to 6 weeks (post-treatment) to 10 weeks (follow-up))
- Paraspinal Muscle Strength(Baseline - 6 weeks (post-treatment))
