Mobilization With Movement in Patients With Osteoarthritis of the Hip

Study Overview
=================
Brief Summary
-----------------
The concept of mobilization with movement, also referred to as a Mulligan mobilization, has not been studied in patients with hip osteoarthritis, subsisting questions about the possible effects in this population. The aim of this randomized controlled study is to compare the immediate effects of Mulligan mobilization with movement technique of pain, range of motion and physical function in patients with osteoarthritis of the hip.

Detailed Description
-----------------
Mulligan original theory for the efficacy of a Mobilization With Movement (MWM) is based on the concept associated with a positional joint failure, which occurs due to injury and may lead to a change in the joint alignment and hence its biomechanical resulting in symptoms such as pain, joint stiffness or weakness. To perform the MWM technique it is required to implement many criteria. During execution is applied an maintained accessory glide in order to correct the positional fault, while a physiological movement or action that usually caused the pain is performed actively or passively. A key component for the MWM is that pain should always be reduced and / or eliminated during application. All study participants will be submitted to an initial assessment protocol to determine the intensity of pain, the range of motion (ROM) in flexion and internal rotation of the hip and the collection of physical function parameters. After that, the intervention will be performed for each group, and then the re-evaluation will be carried out (final evaluation), pain intensity, ROM and physical function tests..

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Real mobilization-with-movement (MWM)<br>In each volunteer of this group, the blind assessor will perform the pre-intervention measurements of intensity of pain, range of motion and physical function tests. Next, the therapist will performed the real mobilization-with-movement. Then, all measurements, before described, will be repeated, by the assessor. | Other: Real mobilization-with-movement (MWM)<br>* For the MWM group, the investigator applied two techniques of mobilization with movement: one for flexion and one for medial rotation of the hip. With the hip in flexion, a stabilizing belt was placed on the medial side of the participant's thigh closest to the joint interline. The belt was placed around the pelvic region of the physical therapist, keeping a perpendicular direction to the participant's thigh. Maintaining a side slip, it was carried out a passive movement of 1) hip flexion (3x10) and 2) medial hip rotation (3x10) by the physiotherapist throughout painless amplitude.<br>* Other names: Group Experimental: mobilization-with-movement (MWM);|
| Sham Comparator: Sham mobilization-with-movement (MWM)<br>In each volunteer of this group, the blind assessor will perform the pre-intervention measurements of intensity of pain, range of motion and physical function tests. Next, the therapist will performed the sham mobilization-with-movement. Then, all measurements, before described, will be repeated, by the assessor. | Other: Sham mobilization-with-movement (MWM)<br>* In the sham group, the investigators conducted a technical simulation. The positioning of the patient and the physical therapist was the same, however, no accessory mobilization was performed with the help of the belt and did not performed repeated movements of passive flexion or medial rotation.<br>* Other names: Group Sham: mobilization-with-movement (MWM);|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in the intensity of hip pain before and after the treatment | Participants were asked to rate the intensity of their pain using an 11-point numerical pain rating scale (NPRS; 0: no pain; 10: maximum pain). | participants will be assessed before and after intervention (interval: 15-20 minutes) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in the range of motion for the hip flexion before and after the treatment | Assess ROM of the hip joint was used a universal goniometer BIOMET® (CAT.No.567330), it was considered a valid instrument to measure hip flexion. | participants will be assessed before and after intervention (interval: 15-20 minutes) | 
| Changes in the range of motion for the medial hip rotation before and after the treatment | Assess ROM of the hip joint was used a universal goniometer BIOMET® (CAT.No.567330), it was considered a valid instrument to measure medial hip rotation. | participants will be assessed before and after intervention (interval: 15-20 minutes) | 
| Changes in the performing time of the physical function test timed up and go before and after the treatment | The Timed Up and Go Test (TUG) is presented as a test that simulates some functional maneuvers of daily life, like, getting up, walking, running laps and siting down. | participants will be assessed before and after intervention (interval: 15-20 minutes) | 
| Changes in the repetitions of the physical function test 30 seg sit to stand before and after the treatment | The 30 sec Sit to Stand test or 30 sec Chair Stand Test (CST) is the functional evaluation of the strength of the lower limbs.Is to repeat the activity of sit and lift a maximum number of times during 30 seconds. | participants will be assessed before and after intervention (interval: 15-20 minutes) | 
| Changes in the performing time of the physical function test 40 m. self placed walk before and after the treatment | The test 40m Self Placed Walk (SPWT) consists is the functional assessment of physical ability of an individual coursing short distances (40 meters). | participants will be assessed before and after intervention (interval: 15-20 minutes) |
