exercise recommended treatment for knee oa
Aerobic, muscle strengthening, and range of motion exercises were highly recommended with a 96% SOR score.
weight loss for some knee oa patients
For overweight patients, weight loss is considered an effective treatment with a 96% SOR score.
knee braces recommended in some cases
For patients with mild to moderate knee instability, knee braces are recommended with a 76% SOR score.
Recommendations include 12 non-pharmacological treatments, including education and self-management, exercise, weight loss, and knee braces. The guidelines also include eight pharmacological treatments and five surgical treatments.
Non-pharmacologic treatments with the highest SOR scores included aerobic, muscle strengthening, and range of motion exercises (96%) and weight loss if the patient is overweight (96%). Knee braces (76% SOR) were recommended for patients with knee OA and mild to moderate varus or valgus instability. The recommendation is primarily based on evidence for valgus bracing and was reached with a 92% consensus.
Relevance to levitation
Unlike the majority of OA knee braces on the market, Levitation offloads all three compartments of the knee and provides a powerful knee extension assist 1– Budarick, A.R. et al. (2020). J. Biomech. Eng. 142(1). As a result of its unique capabilities, Levitation has strong therapeutic value, particularly for individuals with multicompartmental or patellofemoral knee OA 2– Bishop, E.L. et al.

Of further therapeutic relevance, Levitation has been shown to reduce joint loads by an amount equivalent to losing 45 lb bodyweight 3– Budarick, A.R. et al. (2020). J. Biomech. Eng. 142(1). For many OA patients, a loss of 45 lb is considered a clinically relevant decrease that results in noticeable pain relief and multiple functional improvements4– Messier, S.P. et al. (2018) Arthritis Care Res. (Hobokin) 70(11): 1569–1575. As a result, Levitation can provide patients with outcomes similar to weight loss, which has been consistently recommended as a first line of treatment in the management of knee OA 5– Messier, S.P. et al. (2018) Arthritis Care Res. (Hobokin) 70(11): 1569–1575

Levitation can also support adherence to exercise and weight loss regimens by reducing pain, improving function, and supporting increased physical activity levels 6– Budarick, A.R. et al. (2020) J.
