Phantom pain in bilateral upper limb amputation

Abstract

Purpose. To alert health professionals on presence and extent of phantom pain and sensation following bilateral upper limb amputation.

Methods. Of a total of 140 war-related bilateral upper limb amputees in Iran, 103 subjects were thoroughly examined in this cross-sectional study by a physical medicine specialist. The patients were questioned for the presence of phantom pain and sensations, and frequency and intensity of the feeling were recorded.

Results. At 17.1 ± 6.1 years after injury, 82.0% of the 103 amputees suffered from phantom sensation, including varying degrees of phantom limb pain in 53.9% of stumps. Phantom phenomena had a higher frequency in the right extremities, but this was not statistically significant (p > 0.01). Of those amputees who had phantom pain or sensation, 51.2% reported that they ‘always’ had phantom limb sensation; and approximately one-fourth of the subjects (24.6%) ‘always’ had phantom pain. Among the stumps who reported phantom pain (N = 112), the pain was excruciating (38.5%), distressing (34.9%) or discomforting (25.6%). A significant statistical relation between phantom limb sensation and level of amputation was observed (p < 0.01).

Conclusion. At this time there is no healing for phantom pain; medical and surgical modalities only bring temporary relief, and less than 1% of the respondents achieve permanent relief through different treatment methods.
