Objective: To describe the prevalence, intensity, and functional impact of the following types of pain associated with upper-limb loss: phantom limb, residual limb, back, neck, and nonamputated-limb pain., Design: Cross-sectional survey; 104 respondents with upper-limb loss at least 6 months postamputation completed measures of pain intensity, interference, disability, and health-related quality-of-life., Results: Nearly all (90%) of the respondents reported pain, with 76% reporting more than one pain type. Phantom-limb pain and residual-limb pain were the most prevalent (79% and 71%, respectively), followed by back (52%), neck (43%), and nonamputated-limb pain (33%). Although nonamputated-limb pain was least prevalent, it was reported to cause the highest levels of interference and pain-related disability days. Self-reported quality-of-life was significantly lower for individuals with each type of pain compared with those without any pain. Age, time since amputation, and cause of amputation were not associated with pain., Conclusions: In addition to pain in the phantom and residual limb, back, neck, and nonamputated-limb pain are also common after upper-limb loss. All of these pain types are associated with significant disability and activity interference for some individuals, suggesting that assessment of multiple pain types in persons with upper-limb amputation may be important.

This study identified clinical (e.g., etiology) and demographic factors related to prosthesis use in persons with upper- and lower-limb amputation (ULA and LLA, respectively) and the effect of phantom limb pain (PLP) and residual limb pain (RLP) on prosthesis use. A total of 752 respondents with LLA and 107 respondents with ULA completed surveys. Factors related to greater use (hours per day) for persons with LLA included younger age, full- or part-time employment, marriage, a distal amputation, an amputation of traumatic etiology, and an absence of PLP. Less use was associated with reports that prosthesis use worsened RLP, and greater prosthesis use was associated with reports that prosthesis use did not affect PLP. Having a proximal amputation and reporting lower average PLP were related to greater use in hours per day for persons with an ULA, while having a distal amputation and being married were associated with greater use in days per month. Finally, participants with LLA were significantly more likely to wear a prosthesis than those with ULA. These results underscore the importance of examining factors related to prosthesis use and the differential effect that these variables may have when the etiology and location of amputation are considered.

Objective: To examine the types and relative frequency of treatments used for lower-limb phantom limb pain (PLP), including both pharmacologic and rehabilitative interventions., Design: Cross-sectional survey., Setting: Community-based survey from clinical databases., Participants: Community-based sample (N=255) of persons with lower-limb amputations., Interventions: Not applicable., Main Outcome Measures: Intensity of PLP and type and helpfulness of treatments (both past and present) used for PLP., Results: Although 72% of the sample (n=183) reported current PLP, 53% of the respondents with PLP (and 38% of those with severe PLP) had never used treatment for PLP. Those who had used treatment reported greater pain severity and interference. The most commonly used treatment modality was analgesic medication, including acetaminophen, opioids, and nonsteroidal anti-inflammatory drugs. Of the treatments surveyed, only opioids and chiropractic care were rated as moderately to extremely helpful by the majority of those who had tried them, and many pain interventions had been discontinued., Conclusions: As hypothesized, a significant proportion of persons with PLP have not used treatment for this pain, and, among those who have used pain treatments, few treatments are perceived as substantially helpful. More research is needed to identify effective management strategies for PLP and to examine further patient perceptions of pain treatment.

Twenty-four adults with phantom limb pain (PLP) and/or residual limb pain (RLP) participated in a double-blind crossover trial. Participants were randomly assigned to receive gabapentin or placebo and later crossed over to the other treatment, with a 5-week washout interval in which they did not receive medication. Gabapentin was titrated from 300 mg to the maximum dose of 3,600 mg. Measures of pain intensity, pain interference, depression, life satisfaction, and functioning were collected throughout the study. Analyses revealed no significant group differences in pre- to posttreatment change scores on any of the outcome measures. More than half of the participants reported a meaningful decrease in pain during the gabapentin phase compared with about one-fifth who reported a meaningful decrease in pain during the placebo phase. In this trial, gabapentin did not substantially affect pain. More research on the efficacy of gabapentin to treat chronic PLP and RLP is needed.

Purpose: To evaluate the utility of a biopsychosocial model to predict long-term adjustment to lower-limb amputation and phantom limb pain (PLP)., Method: One month after lower-limb amputation, 70 participants completed measures of PLP intensity, cognitions (catastrophizing, perceived control over pain), coping (pain-contingent rest), social environment (social support, solicitous responding), and functioning (pain interference, depressive symptoms). The measures of functioning were administered again at 1- and 2-years post-amputation. Multiple regression analyses were used to examine the ability of the psychosocial variables at 1-month post-amputation to predict changes in the functioning measures over time., Results: The psychosocial variables at 1-month post-amputation, controlling for initial PLP intensity, accounted for 21% of the variance in change in depressive symptoms at 1-year (p < 0.05), and 27% and 22% (p's < 0.01 and 0.05, respectively) of the variance in change in pain interference and depressive symptoms, respectively, at 2-years post-amputation. Catastrophizing and social support were associated with decreases (improvement) in both criterion measures, while solicitous responding was associated with increases (worsening) in both measures., Discussion: The findings support a biopsychosocial model of long-term adjustment to amputation and PLP. In addition, results suggest that some psychosocial variables are more important than others for predicting adjustment, providing important implications for early interventions after amputation.
