The relevance of non-specific variables such as expectation and psychosocial factors in the mechanisms of spinal manipulation cannot be totally dismissed (Bialosky et al. 2009). Expectation of good functional outcomes may decrease pain perception without spinal involvement. In addition, a systematic review indicated that spinal manipulation is associated with better psychological outcomes than verbal interventions (Williams et al. 2007). However, studies done to determine the influence of non-specific cerebral processes in manipulation-induced hypoalgesia have found that manipulation has greater and specific effects on pain sensitivity than expectations of receiving the intervention (Bialosky et al. 2008b, 2014). Nevertheless, additional work is needed to determine whether application of spinal manipulation with increased positive expectations could provide an additive effect on pain perception.
