Running retraining to treat lower limb injuries: a mixed-methods study of current evidence synthesised with expert opinion

Abstract

ImportanceRunning-related injuries are highly prevalent.ObjectiveSynthesise published evidence with international expert opinion on the use of running retraining when treating lower limb injuries.DesignMixed methods.MethodsA systematic review of clinical and biomechanical findings related to running retraining interventions were synthesised and combined with semistructured interviews with 16 international experts covering clinical reasoning related to the implementation of running retraining.ResultsLimited evidence supports the effectiveness of transition from rearfoot to forefoot or midfoot strike and increase step rate or altering proximal mechanics in individuals with anterior exertional lower leg pain; and visual and verbal feedback to reduce hip adduction in females with patellofemoral pain. Despite the paucity of clinical evidence, experts recommended running retraining for: iliotibial band syndrome; plantar fasciopathy (fasciitis); Achilles, patellar, proximal hamstring and gluteal tendinopathy; calf pain; and medial tibial stress syndrome. Tailoring approaches to each injury and individual was recommended to optimise outcomes. Substantial evidence exists for the immediate biomechanical effects of running retraining interventions (46 studies), including evaluation of step rate and strike pattern manipulation, strategies to alter proximal kinematics and cues to reduce impact loading variables.Summary and relevanceOur synthesis of published evidence related to clinical outcomes and biomechanical effects with expert opinion indicates running retraining warrants consideration in the treatment of lower limb injuries in clinical practice.

Exercise prescription for overhead athletes with shoulder pathology: a systematic review with best evidence synthesis

“…For each study, a total quality score was given based on the information provided. Based on risk of bias assessment scores, studies were classified as high quality/low risk of bias (≥20), moderate quality/risk of bias (17–19) or low quality/high risk of bias (≤16) 20. Higher modified Downs and Black checklist scores indicate less risk of bias than lower scores.…”

Is combining gait retraining or an exercise programme with education better than education alone in treating runners with patellofemoral pain?A randomised clinical trial

“…Gait retraining represents another research focus in runners with PFP and aims at modulating forces acting on the PFJ 19. It has been suggested that transitioning from a rearfoot to a forefoot strike pattern can help decrease symptoms and increase functional scores 20 21.…”

“…Is gait retraining effective to treat injured runners? Yes, based on very limited evidence from small-sampled studies 3. But is gait retraining better than other interventions, such as an educated return to running or an exercise programme?…”
