Alteration in phantom pain and sensation with visceral movement.

Some lower limb amputees can present with alteration in phantom pain and sensation with visceral movement (micturition/defaecation). The authors specifically questioned 200 lower limb amputees from 2 amputee rehabilitation centers (150 recent lower limb amputees in the first center and 50 consecutive recent and established lower limb amputees in the second center) for such symptoms. Eight patients from the first center and 5 patients from the second center reported having the phenomenon. In this case series, the authors report the patient-described symptoms, estimate the prevalence, and discuss the likely pathophysiology of the phenomenon.
