Up to 70 % of military amputees suffer phantom limb pain (PLP), which is difficult to treat. PLP has been attributed to cortical reorganisation and associated with impaired laterality. Repeated sessions of mirror therapy (MT) can benefit PLP; however, anecdotal evidence suggests one MT session could be effective. In a one-group pretest and post-test design, 16 UK military unilateral lower limb amputees (median age: 31.0, 95% CI 25.0 to 36.8 years) undertook one 10 min MT session. Visual analogue scale (VAS) pain and laterality (accuracy and reaction time) measurements were taken pre-MT and post-MT. Median VAS PLP did not differ significantly between pre-MT 15 mm (2–53 mm) and post-MT 12 mm (1–31) (p=0.875) scores. For the amputated limb, there were no significant differences between pre-MT and post-MT scores for laterality accuracy, 95.3%, 95% CI 90.5% to 97.6% and 96.7%, 95% CI 90.0% to 99.4%, respectively (p=0.778), or reaction time, 1.42 s, 95% CI 1.11 to 2.11 s and 1.42 s, 95% CI 1.08 to 2.02 s, respectively (p=0.629). Laterality was also not different between limbs for accuracy, p=0.484, or reaction time, p=0.716, and did not correlate with PLP severity. No confounding variables predicted individual responses to MT. Therefore, one 10 min MT session does not affect laterality and is not effective as standard treatment for PLP in military lower limb amputees. However, substantial PLP improvement for one individual and resolution of a stuck phantom limb for another infers that MT may benefit specific patients. No correlation found between PLP and laterality implies associated cortical reorganisation may not be the main driver for PLP. Further research, including neuroimaging, is needed to help clinicians effectively target PLP.
During the recent conflicts in Iraq and Afghanistan, substantial numbers of service personnel survived devastating injuries, presenting significant challenges for early rehabilitation at Queen Elizabeth Hospital Birmingham. Royal Centre for Defence Medicine personnel augmented NHS therapy provision, gaining significant experience in rehabilitating complex trauma. Multidisciplinary working was key to delivering this service, with a unique rehabilitation coordinating officer position established to manage the rehabilitation pathway. A military exercise rehabilitation instructor provided daily gym-based rehabilitation, developing exercise tolerance. Emphasis was placed on early independence, reducing pain, eliminating complications and optimising function. Innovative solutions and non-standard combinations of rehabilitation were required, with therapy working practices redesigned that, we believe, exceed provision elsewhere, including novel applications such as unique patient transfers, specialist seating, additional equipment, problem-solving teaching and early upper limb prosthetic provision. Active pain management allowed engagement in rehabilitation. With limited evidence available, therapeutic modalities attempting to alleviate phantom limb pain centred on patients' ability to engage in treatment. Finally, the requirement to measure change in early trauma rehabilitation was identified, leading to the development of the preprosthetic functional outcome measure. This article aims to document advances made, lessons learned, encourage debate and identify priorities for future research for military complex trauma rehabilitation.
