Forward Head Posture and Hand Function in Dentists

Not yet recruiting

• Conditions: Forward Head Posture

• Registration Number: NCT06989021
• Lead Sponsor: Cairo University

Brief Summary

This observational study investigates the correlation between forward head posture and hand grip strength, pinch grip strength, and wrist joint position sense among dentists aged 23-30 years. The aim is to understand the impact of poor head posture on upper limb function in dental professionals.

Detailed Description

The study evaluates the relationship between craniovertebral angle and upper limb strength and proprioception using hand dynamometers, pinch gauges, and goniometers. Forward head posture is assessed photometrically. A total of 82 participants will be recruited, all dentists, aged 23-30 years, with FHP confirmed by CVA \<50°. Hand grip, pinch grip (tip, palmar, lateral), and wrist joint position sense (flexion/extension) will be assessed in the dominant hand only.

Primary Outcome Measures

Name	Time	Method
Hand Grip Strength	Single assessment at baseline	To assess the strength of the dominant hand and examine its correlation with forward head posture (CVA \< 50°).

Secondary Outcome Measures

Name	Time	Method
