Effects of Neck Proprioception Impairment on Balance in Cervical Spondylosis Patients

The Influence of Cervical Proprioception Deficits on Postural Stability in Patients With Cervical Spondylosis

This observational cross-sectional study aims to investigate the impact of cervical proprioception deficits on postural stability in patients with cervical spondylosis. Using pedobarographic analysis, the study will assess static balance parameters in affected individuals. The main question it aims to answer is: Does Cervical proprioception deficits affect postural stability in patients with cervical spondylosis measured by pedobarographic parameters?

Study Overview

• Status: Not yet recruiting
• Conditions: Postural Stability
• Intervention / Treatment: Device: Pedobarography system (foot pressure plateform); Device: overhead laser pointer

Detailed Description

This cross-sectional observational study intends to investigate the association between cervical proprioception and postural stability in people with cervical spondylosis. Cervical proprioception promotes posture regulation by providing sensory feedback to the central nervous system. Alterations in cervical joint position sensation caused by degenerative alterations can have a negative impact on balance.

Eighty participants with clinically diagnosed cervical spondylosis will be recruited. Each participant will undergo a single evaluation session that includes cervical joint position error testing and postural stability assessment using pedobarographic analysis. Data will be collected on center of pressure sway, weight distribution, and balance parameters under various conditions.

so this study findings can help physical therapists, rehabilitation experts, and clinicians design protocols to improve proprioceptive input and postural control in people with cervical spondylosis. Furthermore, early diagnosis of proprioceptive deficits by pedobarography may enable preventive actions and lower the incidence of falls and related morbidity in this population.

Study Plan

How is the study designed?

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Postural stability measured using a foot pressure platform	Postural stability will be assessed by measuring postural sway using a force platform (stabilometer) under two conditions (eyes open and eyes closed). The primary variable will be the ellipse surface area (mm²) representing the center of pressure sway.	Single assessment at baseline (Day 1)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cervical joint position error (JPE) measured using overhead laser pointer	Cervical proprioception will be measured using a laser pointer repositioning test. Participants will perform active neck movements and attempt to return to the neutral position with eyes closed. The average deviation (in degrees) from the starting point over three trials will be recorded. Errors greater than 4.5° will indicate proprioceptive impairment	Single assessment at baseline (Day 1)
