Massage Therapy on Hamstrings in Patients With Nonspecific Low Back Pain

Study Overview
=================
Brief Summary
-----------------
Effectiveness of a technique of dynamic massage therapy in the hamstrings in patients with nonspecific low back pain.

Detailed Description
-----------------
The main objective of this study is to test the effectiveness of a technique of dynamic massage therapy in the hamstrings in patients with nonspecific low back pain. Secondary objectives are assess whether the technique of dynamic massage therapy increases the extensibility of the hamstrings, assess whether the treatment of hamstrings decreases low back pain and determine whether the application of this technique decreases the disability associated with nonspecific low back pain.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Hamstrings extensibility measured with sit-and-reach test | Fixing a meter stick on top of a solid box so that 26 cm of the ruler extend over the front edge of the box toward the test subject. Used to check the increase in hip flexion. | Two weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Low back pain measured with visual analog scale | The subject indicates the intensity of pain by marking a 100-mm horizontal line with two extremes: no pain and worst imaginable pain. Used to check the decrease low back pain | Two weeks. Participants will be followed for four weeks after completion of the intervention | 
| Low back disability measured with the Oswestry Disability Questionnaire | Oswestry Disability Questionnaire is an important tool to measure functional low back disability. For each section the total possible score is 5: if the first statement is marked the section score = 0; if the last statement is marked, it = 5. If all 10 sections are completed the score is calculated as follows: Example: 16 (total scored) 50 (total possible score) x 100 = 32% | Two weeks. Participants will be followed for four weeks after completion of the intervention |
