“…'Mind' strategies include visualization, while 'muscle' strategies include physical relaxation techniques such as stretching, or Progressive Muscular Relaxation (PMR) (McGrath, 2012). Exposure therapy, whether real or virtual, involves repeated, or graded, exposure to the feared stimulus in the absence of danger, so as to overcome anxiety (Wardle, 1969;Appel, 1976;Kendrick et al, 1982;Sweeney and Horan, 1982;Kim, 2008;McGrath, 2012;Bissonnette et al, 2015;Zyl, 2021;Bellinger et al, 2023;Candia et al, 2023) While individually effective, the studies cannot be used in totality to form an evidence base as each study used entirely different treatment approaches: insight-relaxation, systematic desensitization, behavioral rehearsal, cue-controlled relaxation, breathing exercises, free improvisation, and virtual exposure therapy. Although individual studies report positive results, the heterogeneity of intervention modalities, assessment and outcome measures, and sampling strategies (too small/diverse) preclude firm conclusions regarding the efficacy of any one approach within behavioral interventions (Kenny, 2011;McGrath, 2012;Brugués, 2019).…”
