RESUMEN
The aim of the study was to analyze the current evidence regarding the effect of intradermal injections of botulinum toxin on residual limb hyperhidrosis. A comprehensive search of the MEDLINE and Scopus databases from inception until December 2021 was performed according to the PRISMA guidelines. The search terms used were "botulinum toxins", "botulinum toxins, Type A", "rimabotulinumtoxinB", "amputees", "amputation stumps", "amputation" and "residual limbs". The specific controlled vocabulary of each database was also used (e.g., MeSH). One hundred and thirty-one different studies met this search criteria and were reviewed. Two independent reviewers assessed the quality of the manuscripts. Eight studies met the inclusion criteria for this review. The results demonstrated an improvement in residual limb hyperhidrosis in all studies. Botulinum toxin A or B can be regarded as safe and effective for the treatment of residual limb hyperhidrosis, as well as improving prosthesis use and quality of life.
