Abstract

Background Chronic low back pain (cLBP) is defined as back pain lasting more than 12 weeks in the lumbar and sacral levels of the spine. The intervertebral disc herniation into the vertebral canal may cause pain and affects the transversus abdominis (TrA) and Lumbar Multifidus (ML) muscles that are preferentially attacked in episodes of nonspecific low back pain.

Objectives Compare the effect of stabilizing exercises versus TENS in fatigue of the lumbar multifidus muscle (LM) and the ability to activate the transversus abdominis (TrA) in patients with lumbar disc herniation (LDH).

Methods This study involved 29 patients (age range 25–58 years) randomised into two groups: Stabilisation group (SG: n=15); which received of stabilization exercises (transversus abdominis and lumbar multifidus muscles) and TENS group (TG: n=14), which received electrotherapy. Groups underwent 16 sessions, for 60 minutes, twice a week and they were evaluated before and after eight weeks. The following instruments were used: visual analogue pain scale and McGill Pain Questionnaire for pain, Oswestry Disability Index for functional disability, electromyography (EMG) to evaluate the LM and pressure biofeedback unit (PBU) for ability to contract the TrA. Analyses within and between groups were performed after treatment. One-way analysis of variance was used for intergroup and intragroup comparisons.

Results The stabilisation group was superior to TENS in terms of improvements in fatigue of ML, pain, functional disability and ability to contract the TrA. There were no significant differences in TENS group in terms of disability or ability to contract the TrA muscle.

Conclusions The stabilisation group was superior to TENS in improvements fatigue of ML, pain, functional disability and ability to contract the TrA.
