Effects of Dry Needling Technique in Hip Muscles in Subjects With Grade I-III Hip Osteoarthritis

Dry needling is a new treatment technique, addressed to mechanical pain of the neuromusculoskeletal system. Recent investigations has developed new hypothesis about the etiology of the osteoarthritis and could be in relation to musculoskeletal disorders, but there is no published studies evaluating the results of this technique in hip osteoarthritis patients. The objective of this trial is to evaluate if dry needling is more effective in symptoms, function, range of motion, strength, muscular length, pain threshold and compared to sham dry needling and control. For this purpose the investigators conduct a randomized controlled trial double-blind (patient and examiner). The investigators included patients diagnosed of hip osteoarthritis Grade I-III by Scale of Kellgren and Lawrence. Patients included are randomized into 3 groups one receive Dry needling, other sham dry needling and the other is a control. Groups receive 3 treatment sessions. The variables are measured at the beginning and end of treatment. And also some variables are measured before and after each session. Patients who participated in sham dry needling or control group, when the intervention finish the investigators will be given the opportunity to receive the actual technique.

Dry needling is a skilled intervention that uses a thin filiform needle to penetrate the skin and stimulate underlying myofascial trigger points, muscular, and connective tissues for the management of neuromusculoskeletal pain and movement impairments.

The investigators measure the functional capacity with functional test: "test Up and Go" (TUG), "20 and 40 meters self-placed" and "30 seconds-chair stand" at baseline

The investigators measure the intensity of with a visual analogic scale at the end of the intervention (3 weeks after baseline the investigators measure the intensity of symptoms through study completion, an average 21 days)

The investigator measure the functional capacity with functional test: "Test Up and Go" (TUG test), "20 and 40 meters self-placed" and "30 seconds-chair and stand" at the end of the intervention (through study completion, an average 21 days).

The investigators measure the hip range of motion with an inclinometer at the end of the intervention (through study completion, an average 21 days)

The investigators measure the hip strength with a hand held dynamometer (Lafayette) at the end of the intervention (through study completion, an average 21 days)

The investigators measure the muscular length with Passive Knee Extension test, ELY test, and modified Ober test at baseline

The investigators measure the muscular length with Passive Knee Extension test, ELY test, and modified Ober test at the end of the intervention (through study completion, an average 21 days)

The investigators measure the pain threshold with a digital algometer in myofascial trigger points of the hip muscles, and also other bone areas to discriminate a central sensitization at baseline

The investigators measure the pain threshold with a digital algometer in myofascial trigger points of the hip muscles, and also other bone areas to discriminate a central sensitization at the end of the intervention (through study completion, an average 21 days)

The investigators measure the anxiety and depression with HADS questionnaire at the end of the intervention (through study completion, an average 21 days)

The investigator measure the functional capacity with WOMAC questionnaire at the end of the intervention (through study completion, an average 21 days)

The investigator measure gait pattern in treadmill using wearable inertial sensors to track body kinematics during gait
