Comparison of the Effects of Virtual Reality-Based Interventions on Foot Function, Foot Pressure, and Balance in Sedentary Individuals

Foot Function Assessment

Foot pain, disability, and activity limitation will be assessed using the Foot Function Index (FFI), a validated 23-item questionnaire. The total FFI score ranges from 0 to 100, with higher scores indicating worse foot function (greater pain, disability, and activity limitation).

Time frame: 6 weeks

Foot Pressure Assessment - Maximum Plantar Pressure

Plantar pressure during standing and walking will be assessed using a pedobarographic measurement system. Maximum plantar pressure will be recorded, with higher values indicating greater localized loading on the foot.

Time frame: 6 weeks

Foot Pressure Assessment - Contact Area

The pedobarographic system will measure the total plantar contact area during standing and walking. Larger contact area values indicate greater surface area participation in load distribution.

Time frame: 6 weeks

Foot Pressure Assessment - Center of Pressure (COP)

The pedobarographic system will measure center of pressure displacement during standing and walking. COP path characteristics provide objective indicators of stability and gait mechanics; greater displacement typically indicates reduced postural control.

Time frame: 6 weeks

Balance Performance Assessment

Static and dynamic balance performance will be assessed using the Biodex Balance System. The system provides balance scores ranging from 0 to 12, where lower scores indicate better balance performance.

Time frame: 6 weeks

Physical Activity Level Assessment

Physical activity levels will be assessed using the International Physical Activity Questionnaire (IPAQ) - Short Form. Weekly metabolic equivalent of task (MET-minutes/week) will be calculated to classify physical activity as low, moderate, or high. Higher MET-minutes/week indicate higher physical activity levels.
