Letter to the Editor: Virtual McKenzie extension exercises for low back and leg pain: a prospective pilot exploratory case series. Journal of Manual and Manipulative Therapy, DOI:10.1080/10669817.2092822
Abstract
The authors are to be commended for their work examining the potential benefit of a virtual, motor imagery directional preference treatment approach. Their case series bridges a common mechanical intervention with virtual motor imagery, and the acute effects of this intervention may have implications for the management of low back pain. Methodologically, case reports and case series are helpful in describing novel interventions and are generally intended to guide hypothesis generation. Case series designs are not intended to create generalizable knowledge given the lack of control or comparison groups among other factors [1]. Their investigation is relevant, as low back pain affects up to 80% of individuals within their lifetime and over 126 million adults in the United States have experienced pain over the last 3 months. Additionally, approximately 25.3 million adults are currently experiencing chronic pain, with the potential for psychosocial risk existing chronic low back pain subgroups [2,3]. Interventions, like the virtual motor imagery presented in this manuscript that address psychosocial risk factors associated with chronicity are in great need [4]. The authors included self-reported psychosocial assessment tools including the Fear Avoidance Belief Questionnaire (FABQ) and the Pain Catastrophizing Scale (PCS) to measure psychological impairments. It is well established that such assessment tools can identify psychosocial risk factors. Outcomes from these measures may…
