N2 - CONTEXT: Achilles tendinopathy (AT) is a common musculoskeletal injury among runners. Eccentric exercises are considered first-line treatment. However, during the early stages of rehabilitation, patients are usually instructed to stop running. Backward running (BR) on a negative slope provides a similar eccentric load while enabling ongoing physical activity; thus, it may be suggested as an alternative treatment. OBJECTIVES: To determine the feasibility of a BR program as a treatment option for AT in runners. DESIGN: Prospective, single-arm feasibility study. SETTING: Outpatient clinic. PATIENTS: Recreational runners diagnosed with AT and referred to the Meuhedet Health Services Physical Therapy Clinic in Jerusalem, Israel, from September 2019 to February 2020. INTERVENTION: The patients completed a 5-week (9 sessions) rehabilitation program of supervised BR on a negatively inclined treadmill. MAIN OUTCOME MEASURES: Compliance with the program was evaluated by calculating the percentage of patients who completed the full protocol with no adverse events. Personal running-related goals were set before the program and were assessed following rehabilitation using the goal attainment scaling method. Forward-running time until the onset of relevant Achilles tendon pain, and the Victorian Institute of Sports Assessment Scale-Achilles were measured at baseline (T0), before treatment session 6 (T1), and after the last session (T2). RESULTS: Among the 15 patients recruited, 14 (93%), average age 48.8 (10.4) years (86% males), completed the full protocol with no adverse events. Almost all participants (85.7%) achieved their running-related functional goals. Postintervention, the median forward-running time increased from 52.5 (92.5) to 900 (522.5) seconds (P = .008, effect size = .858), and the median Victorian Institute of Sports Assessment Scale-Achilles score improved by 28 points (P = .003, effect size = .881). CONCLUSIONS: BR on a negative slope may be a feasible treatment method for runners suffering from AT. Future randomized control trials are required to further validate the efficacy of this method.
