Brief Summary

Osteoarthritis (OA) is a non-inflammatory degenerative disease characterized by progressive deterioration of cartilage tissue, synovial membrane, and joint capsule, primarily affecting weight-bearing joints. Individuals with knee osteoarthritis exhibit weakness in the trunk and periarticular muscles. This loss of strength in the trunk and periarticular muscles increases the load on the joint, contributing to the development and progression of the disease. This study aimed to investigate the effects of core stabilization, applied in addition to knee muscle exercise programs, on clinical symptoms and functional capacity in individuals with knee osteoarthritis.

Conditions

Knee Osteoarthritis (Knee OA)

Keywords

Knee osteoarthritis; Core stabilization exercise; Physiotherapy; Function

Outcome Measures

Primary Outcomes (3)

• Sit Ups

  Participants are positioned supine with knees flexed and hands crossed over their shoulders. Their feet are held in place by the researcher, and the individual is asked to perform trunk flexion. The number of repetitions completed within 30 seconds is recorded.

  Baseline-6 weeks follow-up

• Modified Push-Up

  Participants lie face down on an exercise mat with their knees flexed. They are asked to lift their head, torso, and hips off the ground, placing their hands on the floor and extending their elbows, so that they form a straight line. The number of complete repetitions the participant performs while maintaining this straight line within 30 seconds is recorded.

  Baseline-6 weeks follow-up

• Core Endurance Tests

  Core endurance is determined by core endurance tests (right and left lateral bridge test, trunk extension test, trunk flexion test), as defined by McGgill, and the prone bridge test.

  Baseline-6 weeks follow-up

Secondary Outcomes (3)

• 30-Second Sit-Stand Test

  Baseline-6 weeks follow-up

• Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)

  Baseline-6 weeks follow-up

• Single Leg Balance Test

  Baseline-6 weeks follow-up

Study Arms (2)

Experimental Group

EXPERIMENTAL

This group will receive 10 days of conventional physiotherapy (Hot Pack, TENS, Ultrasound) and 6 weeks of routine knee exercises + 6 weeks of core stabilization exercises.

Other: 10 days of conventional physiotherapy (Hot Pack, TENS, Ultrasound) and 6 weeks of routine knee exercises; Other: Six weeks of core stabilization exercises.

Control Group

OTHER

This group will receive 10 days of conventional physiotherapy (Hot Pack, TENS, Ultrasound) and 6 weeks of routine knee exercises.

Other: 10 days of conventional physiotherapy (Hot Pack, TENS, Ultrasound) and 6 weeks of routine knee exercises

Interventions

10 days of conventional physiotherapy (Hot Pack, TENS, Ultrasound) and 6 weeks of routine knee exercises OTHER

For 10 days, conventional physical therapy consisting of Hot Pack, TENS, Ultrasound, and routine knee strengthening exercises was applied in the hospital. These knee exercises were continued for four weeks after the hospital treatment period.

Control Group; Experimental Group

Six weeks of core stabilization exercises. OTHER

For six weeks, Warner et al. A core stabilization exercise protocol, as defined by was provided. This protocol included neutral spine position in hook position, activation of deep abdominal muscles, supine bridge, ipsilateral and contralateral limb movements in hook position, abdominal curl (sit-up), bridge (double and single leg), plank on knees, side plank on knees, clam exercise (without resistance), and modified 100 exercises. The exercises were performed 3 days a week, with 10 repetitions each.
