Forward Head Posture and Hand Function in Dentists
An observational study of Forward Head Posture, run by Cairo University.
Trial 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. Read more about this study

About this study
Official title: CORRELATION BETWEEN HAND, PINCH GRIP STRENGTH, WRIST JOINT POSITION SENSE AND FORWARD HEAD POSTURE AMONG DENTISTS
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.
Read the 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Hand Grip Strength
To assess the strength of the dominant hand and examine its correlation with forward head posture (CVA < 50°).
Measured: Single assessment at baseline
Secondary outcomes (2)
Pinch Grip Strength
To assess the pinch grip strength of the dominant hand and evaluate its correlation with forward head posture.
Measured: Single assessment at baseline
Wrist Joint Position Sense
To evaluate wrist joint proprioception and determine its association with forward head posture.
Measured: Single assessment at baseline
