Effects of Mobilized Balance Platform Exercises on Balance Parameters in Patients With Knee Osteoarthritis

Effects of Mobilized Balance Platform Exercises on Balance Parameters, Functional Status, and Pain in Patients With Knee Osteoarthritis: A Randomized Controlled Trial

This prospective single-blind randomized controlled study aims to investigate the effects of mobilized balance platform exercises on balance parameters, pain, functional status, fear of falling, and kinesiophobia in patients with knee osteoarthritis. A total of 36 patients diagnosed with knee osteoarthritis will be recruited from the outpatient clinic of Gaziler Physical Medicine and Rehabilitation Training and Research Hospital.

Participants will be randomly assigned to one of two groups. The control group will receive conventional physical therapy including transcutaneous electrical nerve stimulation (TENS) and a home exercise program consisting of knee strengthening, balance, range of motion, proprioceptive, and stretching exercises. The intervention group will receive the same conventional treatment in addition to mobilized balance platform exercises using the Huber 360 system.

Pain severity, functional status, balance parameters, fear of falling, and kinesiophobia will be evaluated before and after treatment by an assessor blinded to treatment allocation.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Conventional Physical Therapy; Participants in this group will receive conventional physical therapy including transcutaneous electrical nerve stimulation (TENS) and a home exercise program. The home exercise program will include knee strengthening, balance, range of motion, proprioceptive, and stretching exercises, performed 3 days per week for 20 minutes.	Other: Conventional Physical Therapy; Participants will receive conventional physical therapy including transcutaneous electrical nerve stimulation (TENS) and a home exercise program consisting of knee strengthening, balance, range of motion, proprioceptive, and stretching exercises performed 3 times per week for 20 minutes.
Experimental: Mobilized Balance Platform Exercise; Participants in this group will receive conventional physical therapy including TENS in addition to mobilized balance platform exercises using the Huber 360 system. The exercise protocol will include quadriceps and core strengthening, proprioceptive, balance, and neuromuscular exercises, performed 3 days per week for 20 minutes.	Other: Conventional Physical Therapy; Participants will receive conventional physical therapy including transcutaneous electrical nerve stimulation (TENS) and a home exercise program consisting of knee strengthening, balance, range of motion, proprioceptive, and stretching exercises performed 3 times per week for 20 minutes.; Device: Huber 360 Balance Training; Participants will perform mobilized balance platform exercises using the Huber 360 system. The exercise protocol will include quadriceps and core strengthening, proprioceptive training, balance exercises, and neuromuscular exercises specifically designed for patients with knee osteoarthritis. Sessions will be performed 3 times per week for 20 minutes.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Static and Dynamic Balance Parameters	Balance performance will be assessed using the Huber 360 balance assessment system. Measurements will include static balance with eyes open and eyes closed, single-leg balance performance, and limits of stability.	Before treatment and immediately after completion of the 8-week treatment program

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain Severity Assessed by Visual Analog Scale (VAS)	Pain intensity will be assessed using a 10-cm Visual Analog Scale (VAS) for night pain, resting pain, and pain during movement. Higher scores indicate greater pain severity.	Before treatment and immediately after completion of the 8-week treatment program
Functional Status Assessed by WOMAC	Functional status will be evaluated using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Higher scores indicate worse pain, stiffness, and functional limitation.	Before treatment and immediately after completion of the 8-week treatment program
Functional Mobility Assessed by Timed Up and Go Test	Functional mobility and dynamic balance will be assessed using the Timed Up and Go Test. Shorter completion times indicate better functional mobility.	Before treatment and immediately after completion of the 8-week treatment program
Fear of Falling Assessed by the International Falls Efficacy Scale	Fear of falling during activities of daily living will be evaluated using the International Falls Efficacy Scale. Higher scores indicate greater concern about falling.	Before treatment and immediately after completion of the 8-week treatment program
Kinesiophobia Assessed by Tampa Scale for Kinesiophobia	Fear of movement and reinjury will be evaluated using the Tampa Scale for Kinesiophobia. Higher scores indicate greater fear of movement.	Before treatment and immediately after completion of the 8-week treatment program
