Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Patients with total hip arthroplasty, will be assigned to two different treatment groups.

Blinding Strategy

DOUBLE

Participants Outcome Assessors

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

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1

Rehabilitation Exercises Group 1 will be submitted to an exercise protocol based on muscle strength training, with duration of 6 weeks and frequency of two weekly sessions, lasting 45 minutes.

Group Type EXPERIMENTAL

Rehabilitation exercises

Intervention Type OTHER

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.

Group 2

Postoperative guidance Group 2 will receive an orientation booklet and weekly links from researchers to address possible questions.

Group Type ACTIVE_COMPARATOR

Postoperative guidance

Intervention Type OTHER

Group 2 will receive only guidelines regarding postoperative care.
