Summary

To date, the anti-gravity treadmill, as a representative method of lower body positive pressure treadmills, has been rarely reported for knee osteoarthritis rehabilitation. Purpose: This study aims to evaluate the effect of antigravity treadmill training on pain, gait characteristics, and function in patients with knee osteoarthritis.

Detailed description

The study included 40 patients with knee osteoarthritis who were randomly assigned to one of two groups: the antigravity treadmill group (n=20) or the control group (n=20 ). For 12 weeks, the antigravity treadmill group received training on the Alter G treadmill (75% weight-bearing, 30 minutes per session, three times per week) combined with traditional physical therapy. During the same period, the control group received only traditional physical therapy. The Visual Analogue Scale, Walkway System, and the Western Ontario and McMaster Universities Arthritis Index were used to assess pain, spatiotemporal gait parameters, and patient function, respectively. All outcome measures were obtained pretreatment, post-treatment, and 3 months follow-up assessment.

Conditions

• Knee Osteoarthritis

Interventions

Type	Name	Description
OTHER	antigravity treadmill	An Alter G treadmill (Alter G Pro 200, Alter G Inc, USA) was used to provide training to the patients in the antigravity treadmill group. The Alter G allows the patient to change their body weight from 20% to 100% in 1% increments. The air pressure inside the lower body positive pressure chamber can be adjusted from 0 to 2.0 kilopascal above atmospheric pressure. They are very comfortable to train in for long periods of time and have simple controls for adjusting body weight, speed, and inclination.
OTHER	physical therapy exercise program	Both groups received the same traditional physical therapy program for 12 weeks, three times a week, for 30 min each. The conventional physical therapy treatment consisted of acupuncture transcutaneous electrical nerve stimulation, Hot moist pack, Ultrasound and quadriceps setting
