Postural Rehabilitation for Visual Dysfunction in Forward Head Posture

Postural Rehabilitation Through Motor Control Versus Sensor-based Biofeedback Training for Visual Dysfunction in Forward Head Posture

This assessor-blinded randomized controlled trial aims to compare the effects of motor control training, sensor-based biofeedback training using a wearable inertial measurement unit (IMU), and standardized postural correction exercises on mild visual dysfunction in university students with forward head posture (FHP). The trial seeks to establish whether targeted postural rehabilitation can produce measurable improvements in validated visual and sensorimotor outcomes.

Forward head posture is highly prevalent among young adults due to prolonged screen exposure and sustained cervical flexion. Emerging neurophysiological evidence suggests that cervical alignment influences visual stability through altered proprioceptive input, cervico-ocular reflex mechanisms, and sensorimotor integration. However, no randomized controlled trials have investigated whether correcting FHP leads to measurable improvements in validated visual parameters.
