Effects of lower body positive pressure treadmill on functional improvement in knee osteoarthritis: A randomized clinical trial study.

Background: Knee joint pain and stiffness are the two main symptoms of knee osteoarthritis (OA) and thus restrict a patient's activities, such as walking and walking up and downstairs. The lower body positive pressure (LBPP) treadmill as one of the emerging body weight support system devices brings new hope for exercise-related rehabilitation for knee OA patients.

Aim: To investigate the biomechanical effects and the subjective clinical assessment of LBPP treadmill walking exercise when compared with conventional therapy in mild to moderate knee OA patients.
