Botulinum toxin for calf tightness and long-term heel pain
Treatments studied
Part of Bones, joints & muscles, Pain clinical trials.
This trial tests whether injections of botulinum toxin A can loosen a tight calf muscle and improve long-lasting plantar fasciitis (heel/foot pain). It’s for people whose symptoms have lasted at least a year and who haven’t improved enough with physical therapy.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re between 18 and 75 years old
- Your calf tightness (gastrocnemius contracture) is confirmed with the Silfverskiölds test
- A doctor confirms you have plantar fasciitis, and an MRI shows specific changes in the plantar fascia and heel bone area
- Your foot pain has lasted at least 12 months before the first injection
- You tried conventional physical therapy for at least 3 months, but symptoms didn’t improve much
- You haven’t had surgery for plantar fasciitis before

This trial studies treatments for ongoing heel pain caused by plantar fasciitis (pain in the band on the bottom of your foot). If you qualify, you may receive an injection treatment and be compared with a control group to see what works best.
This study tests a new needle-based method to lengthen a tight Achilles tendon in children, which can help with toe walking or foot pain. The goal is to see if it works well and is safe.
This trial compares botulinum toxin A (“Botox”) to steroid injections for chronic plantar fasciitis, a common cause of heel and foot pain. It aims to see which shot helps symptoms better when other treatments haven’t worked for at least 3 months.
This trial tests whether adding a specific ankle strengthening program after a botulinum toxin injection improves foot lift strength and walking in people with spastic hemiplegia. Botulinum toxin is used to reduce muscle stiffness, and the exercises aim to strengthen the muscles that lift the foot.
This Phase 2 trial tests whether injecting incobotulinumtoxin-A near painful nerves can reduce nerve-type pain in the feet for people with diabetes. If you have lasting, fairly symmetrical pain in both feet, the injections may help calm the nerve pain signals.
This study looks at how botulinum toxin (botox) injections affect the muscles, tendons, and nerves in the lower leg of people who have had a stroke and have a tight, twisted foot (equinovarus). It aims to understand these changes to improve future treatments.
