PURPOSE: This study aims to compare the effectiveness of uphill walking and physical therapy versus physical therapy alone on knee pain, excursion ranges, stride length, and walking speed in individuals with knee osteoarthritis. METHODS: In this randomized clinical trial, 30 patients with knee osteoarthritis participated. Both control and intervention groups received 10-session physical therapy. Moreover, the intervention group received an 8-degree treadmill walking at a speed of 1.1 m/s for 30 min in each session. Outcome measures, including pain, excursion ranges, stride length, and walking speed, were measured at baseline, post-treatment, and a 20-day follow-up. RESULTS: Significant improvements in stride length and walking speed were observed just in the intervention group from baseline to post-treatment (p <= 0.001) and from baseline to follow-up (p <= 0.001). Furthermore, significant improvement in excursion ranges was observed just in the intervention group from baseline to follow-up (p < 0.05). CONCLUSIONS: This study revealed that the addition of uphill walking to physical therapy results in stride length and walking speed improvements and that it also has persistent effects on knee ranges, stride length, and walking speed as compared with physical therapy alone. This clinical trial was registered at irct.ir (study ID IRCT20171115034920N1).
