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

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.

Treatment and study plan

Huber 360 Balance Training

Device

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.

Conventional physical therapy

Other

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.

Primary outcomes

  1. Static and Dynamic Balance Parameters

    Time frame: Before treatment and immediately after completion of the 8-week treatment program

    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.

Secondary outcomes

  1. Pain Severity Assessed by Visual Analog Scale (VAS)

    Time frame: Before treatment and immediately after completion of the 8-week treatment program

    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.

  2. Functional Status Assessed by WOMAC

    Time frame: Before treatment and immediately after completion of the 8-week treatment program

    Functional status will be evaluated using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Higher scores indicate worse pain, stiffness, and functional limitation.

  3. Functional Mobility Assessed by Timed Up and Go Test

    Time frame: Before treatment and immediately after completion of the 8-week treatment program

    Functional mobility and dynamic balance will be assessed using the Timed Up and Go Test. Shorter completion times indicate better functional mobility.

  4. Fear of Falling Assessed by the International Falls Efficacy Scale

    Time frame: Before treatment and immediately after completion of the 8-week treatment program

    Fear of falling during activities of daily living will be evaluated using the International Falls Efficacy Scale. Higher scores indicate greater concern about falling.

  5. Kinesiophobia Assessed by Tampa Scale for Kinesiophobia

    Time frame: Before treatment and immediately after completion of the 8-week treatment program

    Fear of movement and reinjury will be evaluated using the Tampa Scale for Kinesiophobia. Higher scores indicate greater fear of movement.
