The trial is looking for adults with spastic cerebral palsy who can walk. They will train to lower a calf muscle reflex.

Age
18 years and older
Sex
All sexes
Disease stage
Spastic cerebral palsy, Gross Motor Function Classification System level I-III. Must be able to walk at least 10 meters, with or without a walking aid. Stable medical background.
Earlier treatment
Current medicines must stay the same for 3 months. No Botox within 2 months of the study. No past ankle surgery in the affected leg (such as dorsal root rhizotomy). No regular electrical stimulation of leg muscles.
Biomarker or test result
The H-reflex (a calf muscle reflex triggered by a small electric pulse) must be measurable.

Main reasons for not taking part

  • Pregnancy
  • Uncontrolled diabetes or a history of heart conditions
  • Current use of seizure medicines
  • Metal implants, cochlear implants, pacemakers or other implanted devices
  • Skin disorders, damaged skin or latex allergy

About the trial

What the trial wants to find out

12 adults with spastic CP will complete 6 baseline sessions and 24 down conditioning sessions held 3 times/week. All clinical and physiological assessments collected at baseline will be reassessed after study completion, and follow ups after 2 weeks, 1 month and 3 months. The soleus H reflex (electric analogue of the stretch reflex) will be elicited in all sessions. In each session, participants will complete 20 baseline trials and 225 down conditioning trials to decrease the magnitude of the H-Reflex.

The group in the trial

  • Spinal reflex conditioningTreatment being tested

    The OC intervention includes 6 baseline sessions and 24 conditioning/ no conditioning sessions held 3 times/week. To elicit an H-reflex, participants will be asked to stand in a comfortable position. Small pulses of energy will be applied to a nerve in the leg called the tibial nerve. We will record when the participant maintains leg muscle activity. During the intervention, participants will be trained to decrease their reflex in their calf.

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
