Lumbar Stabilization, Strengthening and Stretching in Chronic Low Back Pain
- Conditions
- Chronic Low Back Pain
- Interventions
- Other: Stabilization , strengthening and stretching
- Registration Number
- NCT01124201
- Lead Sponsor
- University of Sao Paulo General Hospital
- Brief Summary
The purpose of this study was to compare the efficacy of three exercise programs in patients with chronic low back pain: Segmental stabilization, superficial strengthening and stretching. Groups were contrasted regarding pain, functional disability and TrA muscle activation capacity. The three groups of exercise improved pain and functional disabilities, and the Segmental stabilization group was better in the ability to recruit TrA muscle.
- Detailed Description
Objective: To contrast the efficacy of three exercise programs, segmental stabilization and strengthening of abdominal and trunk muscle and lumbar stretching on pain, functional impairment, and activation of the transversus abdominis muscle (TrA), in individuals with chronic low back pain.
Design: Forty-five patients were randomized into three groups namely: Segmental stabilization group (ES)(transversus abdominis and lumbar multifidus) (n=15, mean age 42,02 ± 8,15), superficial strengthening group (FS)(rectus abdominis, oblique abdominal muscles and erector spinae muscles) (n=15, mean age 41,71±6,41) and stretching group (AL) (erector spinae, posterior connective tissues and ischiotibials muscles) (n=15 mean age 41,53 ± 4,41). Groups were contrasted regarding pain (visual analogical scale and McGill pain questionnaire), functional disability (Oswestry disability questionnaire) and TrA muscle activation capacity (Pressure Biofeedback Unit = PBU). The program lasted 6 weeks, and sessions happened twice a week, with duration of 30 minutes each. Analysis of variance was used for inter and intragroup comparisons. Significance level was established at 5%.
Patients attended two weekly sessions during six weeks and were evaluated for pain (visual analogue scale and McGill Pain Questionnaire), functional disability (Oswestry disability index), and ability to contract the TrA (Pressure biofeedback unit) before and after the treatment. The treatment program consisted of 30 minutes sessions. The Anova one-way and Tukey´s Post Hoc were used to compare groups. The significance level adopted was 5%.
