  1. Cross-sectional study of alteration of phantom limb pain with visceral stimulation in military personnel with ampuatation Michael Rafferty, MRCS; Thomas M. Bennett Britton, MRCGP; Benjamin T. Drew, MCSP; Rhodri D. Phillip, FRCP

  2. Aim • Investigate the prevalence of the alteration in phantom limb pain intensity. • Relevance • Clinical experience suggests that the augmentation of phantom limb pain with visceral stimulation (sensation of the bowel or bladder either filling or evacuating) is an issue for many military personnel with amputation.

  3. Method • Cross-sectional study of 75 military personnel who have lost one or both lower limbs. • Participants completed questionnaire to assess the prevalence of the alteration of phantom limb pain with visceral stimulation. • Included visual analog scale (VAS) graded 0 to 10. • Recorded presence and intensity of phantom limb pain. • Recorded whether and how pain altered with a need to micturate or micturition, and/or a need to defecate or defecation. • Time since amputation, level of amputation, and medications also recorded.

  4. Results • Phantom limb pain prevalence of 85% with a mean VAS of 3.6. • 56% reported a change in the severity of phantom limb pain with visceral stimuli. • Mean bladder stimulation VAS increase: 2.5 ± 1.6. • Mean bowel stimulation VAS increase: 2.9 ± 2.0. • 65% reported improvement in symptoms over time. • VAS scores highest in those less than 6 mo postamputation.

  5. Conclusion • An increase in phantom limb pain with visceral stimulation is a common problem for military personnel with amputation.
