Botox injections at the heel improve pain and function in patients with chronic plantar fasciitis, according to a new study in the Journal of Rehabilitation Medicine. Fifty patients with chronic heel pain and a diagnosis of plantar fasciitis were divided into two groups. The experimental group received injections of botulinum toxin type A at the insertion of the plantar fascia using ultrasound for guidance and were compared to a control group. The experimental group had significant decreases in pain at 3 weeks and 3 months compared to baseline and compared to the control group. The fat pad thickness was also measured and no change between baseline measurements was noted and there was no significant change compared to the control group. The authors concluded that botulinum toxin is effective at decreasing pain in patients with chronic plantar fasciitis without causing fat pad atrophy (1).
