Study Details

Brief summary:

The purpose of the study is to measure the effects of obturator nerve cryoneurotomy, on clinical measures in adult (ages 19+) and paediatric (ages 12-18) patients with hip adductor spasticity, who will receive this procedure as a part of their treatment based on the spasticity treatment available guidelines. The results will provide us valuable information like how long cryoneurotomy is effective, before regeneration happens

Interventions and Outcome Measures

Primary outcome measure

  • The degree of changes in hip abductors' active range of motion. [ Time Frame: measurement will be done at baseline, 1 month after having Cryoneurotomy and then every 3 months up to one year. ]
  • The degree of changes in hip abductors' maximum passive range of motion. [ Time Frame: measurement will be done at baseline, 1 month after having Cryoneurotomy and then every 3 months up to one year. ]
  • The degree of changes in hip abductors' spasticity [ Time Frame: measurement will be done at baseline, 1 month after having Cryoneurotomy and then every 3 months up to one year. ]
  • The degree of changes in inter knees distance at maximum passive hip abduction range of motion [ Time Frame: It will be done at baseline, 1 month after cryoneurotomy and then every 3 months up to 12 months ]
