    • Age 15 and older

Exclusion Criteria: 

  • Individuals with sCP:
    • Botulinum toxin injection to the muscle of interest in the past 3 months
    • A history of phenol neurolysis to the fibular nerve or sciatic nerve
    • Active titration of oral baclofen or anti-epileptic medications
    • History of a selective dorsal rhizotomy
    • Presence of a baclofen pump
    • Having any other neuromuscular disorder
  • Individuals without sCP:
    • Presence or history of a peripheral or compressive neuropathy
    •  Myopathy
    • Injury to the nerve or muscle of interest
    • Abnormality of the central nervous system (stroke, traumatic brain injury (with presence of spasticity or movement difficulties), spinal cord injury, neurodegenerative condition, or central nervous system tumor)
    • Any other neuromuscular disorder
