Botulinum injections in Plantar fasciitis had an appeal because of the lack of atrophy you can get with steroid inject. Shockwave therapy is an option, and works in more people but pain relief looks same or better in Botulinum group?

- usual treatments for plantar fasciitis have only a modest effect. – I wrote about it here:
Plantar Fasciitis – Need Both Orthotics and Calf Stretching Night Splint To Make a Difference
http://painmuse.org/?p=2482 - 36 in each group
- Extracorporeal Shock Wave (ESWT), “generated by a Piezoson 100 (Richard Wolf, GmbH, Knittlingen, Germany). The target area was the site of maximum local tenderness, found through palpation. Patients were given 3000 focused shock waves with a flux intensity of 12 mJ/mm2, at a pressure of 64mPa and at a frequency of 4 Hz, in just one session. The time of administration was approximately 15 min.”
- Botulinum: – “100 U of BoNT-A were diluted in 1mL of normal saline, and one half of the solutions was injected in the insertion of the plantar fascia in the calcaneus and the other half in the area of maximal tenderness between one inch (2.5 cm) distal to the talar insertion of the plantar fascia and the midpoint of the plantar arch, both sites found through palpation.”
- Both did stretch exercises as recommended by Mayo Clinic:

Comment – so little change cannot comment. Obviously one ESWT is not the best. Fortunately for Botulinum there was a better article.
