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, and standardized postural correction exercises on mild visual dysfunction in university students with forward head posture. 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.

the intervention will be a progressive training starting from the stationary, no inertia and no object manipulation to in motion with inertia and with object manipulation taking help of sitting standing and stepping stairs like activities keep the head in normal position with the help of a laser gun. the intervention duration is 45 minutes/day, with three sessions per week for 4 weeks.
the sensor will be being placed at cervical vertebrae C7 measuring current craniovertebral angle with the threshold being set at 50 degrees. the real time feedback will be shown on the mobile app. and the data will be recorded for whole intervention time. the intervention duration is 45 minutes/day, with three sessions per week for 4 weeks.

RECRUITINGvisual impairment
The mild visual impairment will be measured by LogMar chart. the smallest line that person can read will be recorded as reading of visual impairment. the score is generally in form of fractions.
Time frame: baseline to 8th week
oculomotor function
this will be measured by the near point convergence test. the point at which blurring stated by participant will be measured in cms.
Time frame: baseline to 8th week
visual reaction time
this will be measured on visual reaction time app on phone. the person has to click the screen when the stimulus arrives on screen. The average of 3 readings will be recorded as the visual reaction time
Time frame: baseline to 8th week
visual fatigue
The visual fatigue will be measured by 17 item asthenopia questionnaire (ASQ-17). the score will be marked on 5 point likert scale with greater score shows more severity
Time frame: baseline to 8th week
craniovertebral angle (CVA)
this will be measured by mobile app specified for said purpose. sideways picture will be taken and CVA will be noted from the app.
Time frame: baseline to 8th week
flexor muscle endurance
this will be measure by flexor endurance test as the end of couch in supine lying with head lift in chin tuck in position. the time of hold in seconds will be noted.
Time frame: baseline to 8th week
extensor muscle endurance
the test will be done in prone lying holding the head in static position at the end of couch. the time of hold will be measured in seconds.

the strengthening of deep neck flexors and retractors and stretching of pectoralis major and cervical extensors will be done using intervention duration is 45 minutes/day, with three sessions per week for 4 weeks.
Time frame: baseline to 8th weeks
pelvic tilt
the pelvic tilt will be measured by the pelvic inclinometer in degrees by place its both ends at anterior superior iliac spine.
Time frame: baseline to 8th week
static balance
the static balance will be measured by Balance Error Scoring System test. the readings in double foot stance, single leg stance and tandem stance will be done on firm and foam surface and the composite score will be used. the no. of wrrors in adopting position will be marked as points. total score is 60. lower score indicate good balance.
Time frame: baseline to 8th week
dynamic balance
The dynamic balance will be measured by the Y-balance test in anterior, postero-medial and postero-latertal positions. the composite score according to formula will be taken as final score. the higher score indicates good balance.
Time frame: baseline to 8th week
