Brief Summary

The relevance of this study is given by the feasibility to assess the effect of an intervention program based on the postural control and trunk neuromuscular activity, comparing two methods: stabilization exercises vs. back strengthening exercises, in athletes with low back pain. The main outcomes will be computed by electromyography measurement so that to assess the trunk neuromuscular activation pattern as well as by force platform parameters for determining of postural control. Clinical symptoms such as pain intensity, perception of disability and fear and avoidance will also be computed. This is the first study to compare two intervention methods using the main biological outcomes related to trunk neuromuscular function.

Outcome Measures

Primary Outcomes (1)

• Eletromyography measurement

  EMG estimates, Root Mean Square: RMS (in microvolts unit: uV) and Median Frequency: MF (in Hertz: Hz) will be computed to evaluate the back activation during strength maximal protocol and endurance dynamic test.

  Change from baseline muscular activation at 8 weeks

Secondary Outcomes (1)

• Force platform measurement

  Change from baseline muscular activation at 8 weeks

Other Outcomes (3)

• Visual Analogic Scale

  Change from baseline muscular activation at 8 weeks

• Disability questionnaire

  Change from baseline muscular activation at 8 weeks

• Fear-avoidance questionnaire

  Change from baseline muscular activation at 8 weeks

G1: exercises for lumbar stabilization

EXPERIMENTAL

Specific exercises for lumbar stabilization. The Group 1 (G1) will perform therapy with specific exercises for lumbar stabilization whith the Swiss ball as a therapeutic resource, including warming; stretching of hamstrings, paraspinals, trapezes; phasic perineal exercise; tonic perineal exercise; pelvic lumbar synergism; trunk mobility; mobility of the shoulder girdle; balance; and slow pelvic balance.

Other: G1: exercises for lumbar stabilization

G2: back strengthening exercises

ACTIVE COMPARATOR

Back strengthening exercises. The Group 2 (G2) will perform therapy including strengthning of back muscles on a Roman chair machine for flexion and extension of trunk with load progression from training volume for endurance and strength gains.

Other: G2: back strengthening exercises
