    In this review, studies of all varieties of meridian-tapping and somato-sensory stimulation that are used to disrupt dysfunctional cognitive-emotional patterns are outlined. However, there are a number ofdiffering theories and hypotheses about the mechanisms underlying theobserved therapeutic effects and, indeed, different methods mayoperate through slightly different, albeit related, processes. Thesecompeting hypotheses are a matter of ongoing debate and research.

    2. =hec;s may be carried out, using muscle testing, to ascertainresistances within the energy system to releasing theperturbations generating the distress. If found these arecorrected, using an energy tapping procedure.

    8. The procedure is followed until the sub@ective distress drops toero. This may also be confirmed by muscle testing.

    1. a target image or memory is identified, which evo;es an&iety orother distressing emotion

    . the tapping appears to disrupt the previous patterning of cognitive-emotional response, inducing a dissipation of distress

    9. the tapping is accompanied by a statement of self-acceptance inrelation to the target problem which reduces a common tendencyto resist the desensitisation/

    B. sometimes additional levels of resistance to desensitisation areidentified these ta;e the form of meta-beliefs Cells, 2 / ormeta-motives that lead the person to believe that recovery fromthe emotional problem is dangerous in some way.

The methods do not re$uire the client to relive emotionaltrauma nor re$uire him or her to tal; in detail about the e&perience.This is a considerable advantage in wor;ing with traumatised patients whomay become overwhelmed by simply tal;ing of the traumatic e&perience.!dverse reactions appear e&tremely rare.

In clinical practice theactual tapping procedure is li;ely to be embedded within much moreactivity of a conventional verbal cognitive or psychoanalytic or other/nature. Through the ordinary discourse of psychotherapy, thepractitioner will identify the affective, cognitive, and psychodynamicareas to target with T T or # T. or e&ample, most of a psychotherapysession may consist of verbal en$uiry and e&ploration, with T T%# Tta;ing up the last few minutes after the crucial issues have been clarifiedand understood. 0n the other hand, it is possible to wor; more free-associatively with 4tapping and tal;ing5 since the process appears to allowa more free emergence of psychological material.

    !lthough there is debate in relation to the $uestions of the importanceof tapping on traditionally recognised acupressure points as opposed torandom tapping on the body/, and whether a theory of energy is re$uiredto account for the therapeutic effects of tapping, the evidence for the

    The efficacy of # T has not only been demonstrated to e&ist, but to beconsiderable. ! mar;ed reduction in an&iety, under laboratory conditions,was found to result from a short session of # T and to be sustained at12 month follow-up .
