Abstract
Background and Objective
This systematic, rapid review aimed to critically appraise and synthesise the recent literature (2014‐2019) evaluating the incidence and prevalence of post‐amputation phantom limb pain (PLP) and sensation (PLS).
Databases and Data Treatment
Five databases (Medline, Embase, Emcare, PsychInfo, Web of Science) and Google Scholar were searched, with two independent reviewers completing eligibility screening, risk of bias assessment, and data extraction.
Results
The search identified 1350 studies with 12 cross‐sectional and 3 prospective studies included. Studies evaluated traumatic (n=5), atraumatic (n=4), and combined traumatic/atraumatic (n=6) amputee populations, ranging from one month to 33 years post‐amputation. Study heterogeneity prevented data pooling. The majority of studies had a high risk of bias, primarily due to limited generalisability. Three studies evaluated PLP incidence, ranging from 2.2% (atraumatic; one month) to 41% (combined; three months) and 82% (combined; 12 months). Only one study evaluated PLS/telescoping incidence. Across contrasting populations, PLP point prevalence was between 6.7%‐88.1%, one to three‐month period prevalence was between 49%‐93.5%, and lifetime prevalence was high at 76%‐87%. Point prevalence of PLS was 32.4%‐90%, period prevalence was 65% (one month) and 56.9% (three month), and lifetime prevalence was 87%. Telescoping was less prevalent, highest amongst traumatic amputees (24.6%) within a one‐month prevalence period. Variations in population type (e.g., amputation characteristics) and incidence and prevalence measures likely influence the large variability seen here.
Conclusions
This review found that lifetime prevalence was the highest, with most individuals experiencing some type of phantom phenomena at some point post‐amputation.
