Brief Summary

The aim of this study is to investigate the effect of a clinical Pilates exercise program on reducing symptoms in individuals with hip osteoarthritis. The main questions it aims to answer are:

• Does a clinical Pilates exercise program have an effect on pain, range of motion, physical function, performance, spinal mobility, postural control, disability, self-efficacy, and quality of life in individuals with hip osteoarthritis?
• Does a conventional therapeutic exercise program have an effect on pain, range of motion, physical function, performance, spinal mobility, postural control, disability, self-efficacy, and quality of life in individuals with hip osteoarthritis? Researchers will compare clinical pilates program to conventional therapeutic exercise program to see if exercise works to reducing hip osteoarthritis symptoms.

Participants will:

• Take clinical pilates or Conventional Therapeutic Exercise twice a week for 12 weeks
• The patients will be assessed by a blind evaluator both before and after the treatment.

Detailed Description

The clinical Pilates group will perform 45-minute exercise sessions under the supervision of a physiotherapist twice a week for 12 weeks, focusing on fundamental spinal alignments and Pilates principles. The program will include exercises that engage all body segments and combine movement with breathing. Participants will progress to more advanced levels as long as they can maintain proper alignment. Clinical Pilates exercises are structured into three levels of difficulty, and participants who complete the current level without compromising alignment will advance to the next level. The Conventional Therapeutic Exercise group will participate in an exercise program under the supervision of a physiotherapist twice a week for 12 weeks. The program, consisting of stretching and strengthening exercises, will last approximately 45 minutes. Resistance bands will be used to facilitate progression. Based on the individual's perceived difficulty level, resistance bands will be introduced or adjusted by changing their color to increase or decrease resistance.

Study Groups

Clinical Pilates Group

The patients participated in a Clinical Pilates program under the supervision of a physiotherapist twice a week for a duration of 12 weeks.

Group Type: EXPERIMENTAL

Exercise

Intervention Type: OTHER

Clinical Pilates Session:

Each clinical Pilates movement will have three difficulty levels: beginner, intermediate, and advanced. The progression criteria for increasing difficulty will be determined by the prevention of compensatory movements, the ability to activate target muscles, achieving more controlled movements during exercise, and maintaining a more stable posture. This program will include standard hip-focused as well as full-body clinical Pilates movements.

Conventional Therapeutic Exercise Program

The patients participated in a Conventional Therapeutic Exercise program under the supervision of a physiotherapist twice a week for a duration of 12 weeks.

Group Type: EXPERIMENTAL

Exercise

Intervention Type: OTHER

Conventional Therapeutic Exercise Program:

The Conventional Therapeutic Physiotherapy Exercise Program will consist of strengthening exercises for the hip flexors, extensors, abductors, and adductors, as well as the knee flexors and extensors. Additionally, stretching exercises for the hip flexors, extensors, abductors, and adductors, as well as the knee flexors and extensors, will be included. Stretching exercises will be performed at a pain-free point where tension is felt, holding for 10-30 seconds to achieve a total duration of 60 seconds per muscle group. These exercises will represent standard hip-targeted exercises.

During the exercises, patients will be asked to rate their perceived exertion using the BORG scale (0-10). When the difficulty level reaches 5-6 points, progression will first be achieved by increasing the number of sets, followed by the use of resistance bands.
