摘要
目的 明确跑鞋跟掌落差(5、0、-11 mm)对髌股关节痛跑者跑步时髌股关节和跟腱负荷特征的急性影响.方法 16 名髌股关节痛跑者穿着不同跟掌落差的跑鞋进行跑步测试,应用红外动作捕捉系统和三维测力台采集体表标志点和地面反作用力数据,基于髌股关节和跟腱生物力学模型计算髌股关节应力、跟腱力等参数.结果 与正跟鞋相比,穿着负跟鞋在 39%～47%支撑期髌股关节应力(P<0.001)、支撑期髌股关节最大应力及冲量(P<0.05)较小,但在 12%～46%支撑期跟腱力(P<0.001)及支撑期跟腱力冲量较大(P=0.001).与零跟鞋相比,穿着负跟鞋在 12%～31%支撑期跟腱力(P<0.001)及支撑期跟腱力冲量(P=0.023)较大.结论 与正跟鞋相比,髌股关节痛跑者穿着负跟鞋跑步时髌股关节应力和冲量较小,可能可以限制髌股关节痛的进一步发展;与零跟鞋和正跟鞋相比,穿着负跟鞋跑步时跟腱力和跟腱力冲量较大,可能增加跟腱损伤风险.建议髌股关节痛跑者在更换负跟鞋前先进行适应性训练,从而在不增加跟腱损伤风险的同时限制髌股关节痛的进一步发展.
Abstract
Objective To determine the acute effects of heel-to-toe drops(5,0,-11 mm)of running shoes on the loading of the patellofemoral joint and Achilles tendon(AT)in runners with patellofemoral pain(PFP)during running.Methods Sixteen runners with PFP completed a running test while wearing running shoes with different heel-to-toe drops.The retroreflective markers and ground reaction force were measured using an infrared motion capture system and a three-dimensional force plate.The patellofemoral joint stress(PFJS)and AT force were calculated based on biomechanical models of the patellofemoral joint and AT.Results When runners with PFP ran in negative-heel shoes,the PFJS(P<0.001)during 39%-47%of the stance phase,maximum PFJS,and cumulative PFJS(P<0.05)during the stance phase were lower than those in positive-heel shoes.Meanwhile,the AT force(P<0.001)during 12%-46%of the stance phase and cumulative AT force(P=0.001)during the stance phase were larger than those in positive-heel shoes.The AT force(P<0.001)during 12%-31%of the stance phase and cumulative AT force(P=0.023)during the stance phase in negative-heel shoes were higher than those in zero-heel shoes.Conclusions Compared with runners with positive-heel shoes,runners with PFP running in negative-heel shoes had decreased PFJS and cumulative PFJS.This may potentially reduce the risk of further development of PFP.However,compared with zero-and positive-heel shoes,running in negative-heel shoes increases the AT force and cumulative AT force.This may increase the risk of AT injury.Runners with PFP are recommended to undergo acclimatization before shifting to negative-heel shoes.This would limit further progression of PFP without increasing the risk of AT injury.
