Introduction Knee osteoarthritis (KOA) is a prevalent degenerative joint disorder, often accompanied by comorbidities like type 2 diabetes mellitus (T2DM). These conditions have a significant impact on patients' sleep quality and metabolic health.
Current treatments for KOA primarily focus on symptom management, while innovative approaches targeting interconnected health outcomes remain underexplored. The lumbar knee recovery device, a non-invasive device patented in Iran, offers potential benefits by enhancing lumbar-knee synchronisation, improving blood circulation and optimising cellular metabolism.
This randomised controlled trial (RCT) aims to evaluate the device's effectiveness in improving sleep quality and regulating blood glucose levels in diabetic patients with KOA. Methods and analysis This RCT aims to evaluate the impact of using the lumbar knee recovery device (Kamarasa) on sleep quality, blood glucose levels, HbA1c (blood glucose control level over the past 90 days) and body mass index (BMI) in patients with T2DM and grade 1 - 3 KOA.
The study will be conducted at the Orthopedic Clinic of Imam Khomeini Hospital, Tehran, and the Health and Wellness Clinic.
