Knee Osteoarthritis, Balance; Distorted, Proprioceptive Disorders
Conditions
Brief summary
This study aime to investigate the effects of balance and proprioception exercises using two different methods (classical balance training and Balance System™ SD) in addition to strengthening exercises on dynamic balance, pain, functional status and quality of life in patients with knee osteoarthritis (OA).
Detailed description
It is known that knee OA leads to a decrease in proprioception and balance disturbances. Falls due to balance disorders often occur during dynamic activities such as walking and stair climbing. Therefore, correction of balance disorders is of great importance to prevent falls and associated fractures in the elderly population, in which knee OA is common. In addition, loss of proprioception in the knee joint, muscle weakness, and balance disorders are also known to contribute to the development of knee OA itself. Therefore, treatment of balance disorders may also slow the progression of the disease. This study was planned to compare the effects of isometric strengthening exercises plus balance and proprioception exercises performed by two different methods with isometric strengthening exercises alone. This is a single-center randomized trial with 3 parallel arms.

Inclusion criteria
* Patients were included if they had a knee OA diagnosis according to the American College of Rheumatology (ACR) diagnostic criteria, had suffered from knee pain for at least six months, had radiologically verified bilateral knee OA of grade II or III according to the Kellgren-Lawrence classification and had not previously participated in a regular exercise program.
Exclusion criteria
* Patients who had undergone knee surgery, who had received hyaluronic acid or corticosteroid injections into the knee within six months, and patients with conditions that might affect balance were excluded from the study.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Dynamic balance | Baseline | The postural stability test, was performed with the following parameters: Duration: 20 seconds, Stability level: 8, and Stance: two legs. The value of overall stability index (OSI) is obtained by calculating the standard deviations of the degrees of inclination with respect to the zero point (locked position). Higher values indicate poorer equilibrium. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pain score | Baseline | Patients' pain scores at night, at rest, and during movement were measured using visual analogue scale (VAS) (0-10 cm; 0 indicates no pain and 10 indicates severe pain). |
| Physical function | Baseline | Physical function was assessed using the 30-second chair stand test (30CST) , which is recommended by the Osteoarthritis Research Society International (OARSI). Patients sit in a chair with the knees bent slightly more than 90 degrees and the feet on the floor at an angle behind the knees. While arms are crossed in front of the chest, patients stand up with lower limbs fully extended and sit back down with full contact to the chair. The movement of standing up and sitting down is counted as one cycle. The number of cycles during the 30-second period is recorded. Increasing values indicate good performance. |
| Quality of life (QoL) | Baseline | QoL of patients was assessed using the QoL subscale of the Knee Injury and Osteoarthritis Outcome Score (KOOS). The KOOS consists of five subscales assessing pain, other symptoms, activities of daily living, sports and leisure time, and QoL. Each question is scored on a five-point scale ranging from 0 to 4. Scores close to 100 represent good outcomes, while scores close to 0 represent poor outcomes |
