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.

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..

Inclusion Criteria:

clinical criteria for the diagnosis of osteoarthritis of the hip (sensitivity 86% and specificity 75%) are:

• Medial hip rotation ≥15º, pain during medial rotation of the hip, morning fatigue in hip> 60 minutes and older than 50 years or
• Medial hip rotation <15, hip flexion ≤ 115

Exclusion Criteria:

• Previous surgery or hip replacement or knee joint
• Another surgery in the lower extremities performed within 6 months, rheumatoid arthritis
• Uncontrolled hypertension or risk (moderate - high) of cardiac complications during exercise
• Disability unrelated to the hip or knee to prevent the safe participation during exercise, appliance of manual therapy or during march: vision problems affecting mobility, body weight equal to or greater than 155 kg, primary neurogenic disorder or significantly limitation of the lumbar level,advanced osteoporosis with manual therapy or other treatment technique that may interfere with the study
• With inability to understand the instructions and complete the study assessments
