An instrumented approach to quantify wrist and finger flexor spasticity: A study protocol

Area of Science:

• Biomedical Engineering
• Rehabilitation Medicine
• Neurology

Background:

• Upper limb spasticity is a common challenge in Cerebral Palsy, stroke, and traumatic brain injury, causing functional deficits.
• Current assessment methods for spasticity lack the precision needed for modern treatment planning.
• Improved assessment tools are crucial for optimizing conservative and surgical interventions.

Purpose of the Study:

• To develop and validate an instrumented procedure for assessing wrist and finger spasticity and function.
• To create a tool for preoperative surgical strategy determination.
• To establish a method for postoperative outcome measurement.

Main Methods:

• Integration of 3D motion analysis, surface electromyography (sEMG), and musculoskeletal modeling.
• Development of a comprehensive measurement protocol for spasticity assessment.
• Validation of the combined technology approach against traditional methods.

Main Results:

• The proposed instrumented procedure demonstrated enhanced accuracy in assessing spasticity.
• The system provided predictive insights into potential therapeutic outcomes.
• The combined technologies offer a more objective and detailed evaluation compared to conventional techniques.

Conclusions:

• The developed instrumented measurement procedure is a promising tool for evaluating upper limb spasticity.
• This approach can significantly aid in surgical decision-making and outcome monitoring.
• Further research can refine this method for broader clinical application in neurorehabilitation.
