Brief summary (from the registry)
The purpose of this research is to collect safety and efficacy data on injection of botulinumtoxinA (AbobotulinumtoxinA /Dysort) into the gastrocnemius (calf) muscle to improve equinus (lack of flexibility to bring the top of the foot towards the front of the leg) in subjects with plantar fasciitis and relieve pain associated with this condition. The use of AbobotulinumtoxinA is considered experimental in this study because it has not been approved by the United States Food and Drug Administration (FDA) for the treatment of plantar fasciitis.
