Subtalar joint (STJ) range of motion is most critical during the support phase of the gait cycle. The purpose of this study was to determine what differences exist between measures of maximal STJ eversion in open chain and closed chain positions. STJ eversion as a component of STJ pronation was measured in nonweightbearing (NWB) and full weightbearing (WB) positions on 17 subjects who had no significant biomechanical or orthopaedic abnormality. STJ WB eversion was significantly greater than NWB passive ROM. These results indicate that accurate assessment of STJ eversion as a component of pronation requires measurement in a functional WB position as well as in a NWB position. Rehabilitation of persons with lower quarter injuries or disabilities require assessment of ROM in WB positions so that a more accurate and complete evaluation can be done allowing the clinician to make an appropriate diagnosis and treatment.J Orthop Sports Phys Ther 1988;9(9):310-314.
距下关节（STJ）的活动范围在步态周期的支撑阶段最为关键。本研究的目的是确定在开链和闭链位置下，最大 STJ 外翻测量值之间存在哪些差异。17 名受试者在无负重（NWB）和全负重（WB）位置下测量 STJ 外翻，作为 STJ 旋前的一部分，这些受试者没有明显的生物力学或骨科异常。STJ 的 WB 外翻明显大于 NWB 的被动 ROM。这些结果表明，要准确评估作为旋前一部分的 STJ 外翻，需要在功能 WB 位置以及 NWB 位置进行测量。对下肢损伤或残疾患者进行康复治疗时，需要在 WB 位置评估 ROM，以便进行更准确和完整的评估，从而使临床医生能够做出适当的诊断和治疗。《矫形与运动物理治疗杂志》1988 年；9（9）：310-314。
