PROPRIOCEPTION, KINESIOPHOBIA AND FUNCTIONAL RECOVERY AFTER GONARTHROSIS SURGERY

THE RELATIONSHIP BETWEEN PROPRIOCEPTION, KINESIOPHOBIA, BALANCE, AND SENSORY PROFILE WITH FUNCTIONAL RECOVERY AFTER GONARTHROSIS SURGERY

This observational study aims to investigate the relationships between proprioception, causes of kinesiophobia, sensory processing characteristics, and functional recovery in individuals undergoing gonarthrosis surgery. Postoperative functional recovery can be influenced by sensorimotor and psychological factors such as impaired proprioception, fear of movement, and changes in sensory processing. However, the interaction between these factors has not been sufficiently clarified. Participants will complete a sociodemographic and clinical information form, the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), the Causes of Kinesiophobia Scale, and the Adolescent/Adult Sensory Profile. Proprioception will be assessed using the Joint Position Perception Test.

Study Overview

• Status: Not yet recruiting
• Conditions: Knee Osteoarthritis (OA)

• Study Type: Observational
• Enrollment (Estimated): 75

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Adult; Older Adult
• Accepts Healthy Volunteers: No

• Sampling Method: Non-Probability Sample

Study Population

The study population will consist of individuals who have undergone surgery for gonarthrosis and are admitted for follow-up evaluation at an orthopedic clinic. Participants who meet the inclusion criteria and provide informed consent will be included. The study will evaluate the relationship between proprioception, causes of kinesiophobia, sensory processing characteristics, and functional recovery in this population.

Description

Inclusion Criteria:

• The study included individuals aged 50-75 years who had undergone unilateral total knee arthroplasty and were 4-6 weeks post-operatively. Participants were required to have the cognitive capacity to understand the study instructions and to be able to walk independently.

Exclusion Criteria:

• Individuals who had undergone bilateral total knee arthroplasty, those with advanced osteoarthritis in the other knee, those with neurological or orthopedic diseases affecting mobility, those who had undergone another major joint surgery within the last six months, and those with vestibular system disease were excluded from the study.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Womac	Womac is a widely used, self-administered questionnaire designed to evaluate pain, stiffness, and physical function in patients with knee or hip osteoarthritis. It consists of 24 items (5 for pain, 2 for stiffness, 17 for physical function). Higher scores indicate worse symptoms and greater functional limitations.	04.04.2026-05.05.2026

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Berg Balance Scale	The Berg Balance Scale is a 14-item, 0-56 point scored, highly valid, objective performance test used to measure static and dynamic balance and assess fall risk. It includes daily living movements such as getting up from a chair, standing, standing on one leg, and turning over.	04.04.2026-05.05.2026
Proprioception Assessment	Proprioception (deep sense) assessment measures the body's ability to perceive its position in space, its movement, and joint angles.	04.04.2026-05.05.2026
The Causes of Kinesiophobia Scale	This is a validated and reliable tool in Turkish that helps identify the biological and psychological causes underlying fear of movement. It evaluates pain, fear of re-injury, and functional limitations in terms of their biological and psychological sub-dimensions. It is used in cases of chronic pain and avoidance of movement.	04.04.2026-05.05.2026
The Adolescent Sensory Profile	The Adolescent Sensory Profile is a scientific assessment tool that measures individuals' responses to sensory stimuli (sound, light, texture, movement, smell) in daily life. By identifying sensory processing patterns, it analyzes how sensitive a person is to environmental inputs or how they seek out these inputs.	04.04.2026-05.05.2026
