In the intervention group, botulinum toxin A was injected to reduce pain in patients and normal saline was injected in placebo group. Patients' pain relief was assessed at 0, 2, 4, 8, and 16 weeks of the treatment. Data were analyzed using SPSS 23 software.

This reduction was also seen in regard to the cause of amputation, such as war, accidents, and unknown causes.
