Nils Silfverskiöld was an orthopaedic surgeon, Swedish aristocrat, bon vivant, Olympic gymnast, left wing intellectual and anti-Nazi who described that the force required to dorsiflex the ankle in spastic equinus contracture decreased with knee flexion in isolated gastrocnemius contracture. He advocated detaching the origins of the gastrocnemii from the femur and reattaching them to the tibia. The Silfverskiöld knee flexion test has now also been adapted to distinguish between isolated gastrocnemius contracture and combined shortening of the gastrocnemius-soleus complex in non-spastic contracture by measuring the range of ankle dorsiflexion with the knee flexed and the knee straight.
尼尔斯·西尔弗斯凯尔德是一位矫形外科医生、瑞典贵族、美食家、奥运体操运动员、左翼知识分子和反纳粹分子，他描述了在单纯性比目鱼肌挛缩的情况下，背屈踝关节所需的力随着膝关节的屈曲而减小。他主张将比目鱼肌的起点从股骨上分离，并将其重新附着到胫骨上。现在，西尔弗斯凯尔德膝关节屈曲试验也已经被改编，通过测量膝关节屈曲和伸直时踝关节背屈的范围来区分非痉挛性挛缩中的单纯性比目鱼肌挛缩和比目鱼肌-跟腱复合体的联合缩短。
