Clinical and personal equipoise exists when a clinician has no good basis for a choice between two or more care options or when one is truly uncertain about the overall benefit or harm offered by the treatment to his/her patient. For most manual therapy trials, equipoise does not likely exist. Because of the nature of the intervention a lack of equipoise can lead to bias and may account for a portion of the 'effect' that has traditionally been assigned to the intervention. Although there are methodological mechanisms to reduce the risk of bias associated with a lack of equipoise, most of the manual therapy trials to date are likely guilty of this form of bias.
当临床医生在两种或更多治疗选择之间没有充分的依据做出选择时，或者当确实不确定某种治疗方法对其患者的总体益处或危害时，就存在临床和个人平衡。对于大多数手法治疗试验而言，可能不存在平衡。由于干预措施的性质，缺乏平衡可能导致偏差，并且可能是传统上归因于该干预措施的部分“效果”的原因。尽管有方法学机制来降低与缺乏平衡相关的偏差风险，但迄今为止，大多数手法治疗试验可能都存在这种形式的偏差。
