Hip Osteoarthritis
Conditions
Brief summary
Subjects submitted to unilateral THA will be randomized into two rehabilitation groups. One group will receive a booklet with guidelines for postoperative care, while the other group will participate in face-to-face sessions with exercises with emphasis on muscle strengthening.
Detailed description
Individuals with osteoarthritis (OA) of the hip submitted to total hip arthroplasty (THA) may present alterations in their functional capacity, and associated, among other aspects, the reduction in muscle strength. Our overall objective is to compare the effects of an exercise program based on training of muscular strength to orientations and functional home exercises in patients submitted to THA, as well as to compare the outcomes of both groups with those of healthy individuals. Individuals with THA will be randomly assigned to two groups. One group will receive face-to-face treatment (G1) and the other will receive postoperative guidance (G2). A blinded appraiser regarding the allocation will apply the evaluation tools at the moments: preintervention, after completing 7 days and after 10 weeks of the end of the treatment. The research will present as clinical outcomes: the muscular strength, through the values of torque peaks obtained in dynamometry; the functional capacity through the results of the Timed Up and Go test and the Harris Hip Score questionnaire; the range of joint motion measured with and flexometer; the pain through the results of the numerical scale of pain; and kinesiophobia, through the scores obtained in the Tampa Scale.
Interventions
Patients in group 1 will participate in a physical exercise protocol supervised by a physiotherapist. The sessions will focus on the rehabilitation of muscle strength and the exercises will be performed with increased external load.
OTHERPostoperative guidance
Group 2 will receive only guidelines regarding postoperative care.

Masking description
The random allocation step will be conducted through Randomizers - www.random.org by a research assistant. The assistant responsible for randomization will not be involved in any other phase of the study and the secrecy of the allocation will be maintained through opaque envelopes. A second independent assistant will administer the agenda and all communication between the participants and the researchers involved
Intervention model description
Patients with total hip arthroplasty, will be assigned to two different treatment groups.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 6 Weeks Post-Intervention Muscle Strength | Will be measured post intervention 6 weeks after intervention). | Muscle strength will be measured by a portable dynamometer and represented as muscle torque (N.m). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Functional Capacity (HHS) | Will be measured pre-intervention (30 days after the surgery), and two moments post intervention (1 week after intervention and 6 weeks after intervention). | Functional capacity will be evaluated through the harris hip score questionnaire. |
| Hip Range of Motion | Will be measured pre-intervention (30 days after the surgery), and two moments post intervention (1 week after intervention and 6 weeks after intervention). | Hip range of motion will be measured with a flexometer and presented in degrees of movement. |
| Pain in the operated hip (last seven days) | Will be measured pre-intervention (30 days after the surgery), and two moments post intervention (1 week after intervention and 6 weeks after intervention). | The patient will be asked about pain felt in the operated hip within the last 7 days. Pain will be assessed with the numeric pain scale and will be represented by the number selected by the patient. |
| 1 Week Post-Intervention Muscle Strength | Will be measured post intervention (1 week after intervention). | Muscle strength will be measured by a portable dynamometer and represented as muscle torque (N.m). |
| Pre-Intervention Muscle Strength | Will be measured pre-intervention (30 days after the surgery). | Muscle strength will be measured by a portable dynamometer and represented as muscle torque (N.m) |
| Functional Capacity (TUG) | Will be measured pre-intervention (30 days after the surgery), and two moments post intervention (1 week after intervention and 6 weeks after intervention). | Functional capacity will be evaluated through the timed up and go test. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Length of Lower Limbs | Will be measured pre-intervention (30 days after the surgery), and two moments post intervention (1 week after intervention and 6 weeks after intervention). | Length of lower limbs will be performed through a tape measure and presented in centimeters. |
| Kinesiophobia | Will be measured pre-intervention (30 days after the surgery), and two moments post intervention (1 week after intervention and 6 weeks after intervention). | For the evaluation of the kinesiophobia will be used the Tampa Scale. |
| Body Mass Index | Will be measured pre-intervention (30 days after the surgery), and two moments post intervention (1 week after intervention and 6 weeks after intervention). | Body mass index will be acquired by measuring weight and height, and presented in form of the equation mass/height². |
| Femoral Offset | Will be measured pre-intervention (30 days after the surgery), and two moments post intervention (1 week after intervention and 6 weeks after intervention). | Evaluation of femoral vertical and horizontal offset, using radiography exams. |
