Outcome Assessment Of Sun Manipulation In Acute Ankle Sprains: A Randomized Controlled Trial

Background:Acute ankle sprains(AAS) is a common sport injury in daily life.There are nearly 25%among allof musculoskeletal system injury belonging to acute ankle sprains.Without timely and appropriate therapy,a series clinical problems will occur,including pain,joint instability,or a high risk of causing osteoarthritis,et al.How to relieve pain and eliminate joint swelling are the key points in early treatment of AAS.Till now,conventional treatment of)AS is "RICE"(Rest,Ice,Compression, Elevation),pain management and early functional exercise.Conventional medicine believes that ice-compress can contract small vessels to reduce bleeding,and to lower the local inflammatory response and exudation.AAS in Traditional Chinese medicine is known as "tendon injury", manipulation is one of the primary treatments.Professor ShuChun Sun is one of the most famous practitioners of Orthopedic of Traditional Chinese medicine. He has had rich experiences in AAS therapy using manipulation.The manipulation he practiced in tendon injury management has been entitled as "Sun Manipulation".Prof.Sun insists that manipulation should be applied at an early stage of AAS.Although this point of view has not yet been widely accepted by mainstream medicine,more and more cases who were treated by Sun Manipulation have shown a potential trend of efficacy in reducing pain and a long-term stable function of the sprained ankle.In recent years,some manuscripts had been published in terms of applying Manipulation to therapy AAS.However,few of these were randomized controlled trials,moreover,no study comparing with the existing conventional treatment has been published.Object: A pilot study of randomized RICE therapy controlled'trial to evaluate the efficacy of Sun Manipulation in acute ankle sprains,And to observe the safety of the Sun Manipulation.Method:18 cases of acute ankle sprain were enrolled and were randomly divided into the treatment group(n=9) and the control group(n=9),the follow-up duration is 1 week.Result:No significant effect could be found between the treatment group and the control group(P＞0.05),but the treatment group's pain-score of pre-treatment was more than the control group(P＜0.05),implied that the treatment group might have potential effect on pain release comparing with the control group. The treatment group showed significant effect of reducing swelling than the control group(P＜0.05).The cumulative pain duration and pills counting had no significant results between two groups(P＞0.05).Pre-treatment and post-treatment compared results showed that the potential clinical effect of reduce swelling and pain were significant in the treatment group(P＜0.05). Analgesic effect was significantly in control group(P＜0.05),however the result was not significant in reducing swelling(P＞0.05).No adverse effect was found.Conclusion:Potential effect of Sun manipulation in acute ankle sprains has been found in reducing swelling.Larger sample may be needed in achieving a more confident efficacy.
