Quantitative evaluations of ankle spasticity and stiffness in neurological disorders using manual spasticity evaluator

Qiyu Peng, PhD, et al.


Figure 1. Manual spasticity evaluator used to measure spasticity at human ankle. With subject???s leg fixed to leg support, operator moves ankle at controlled velocity and terminal torque with real-time feedback. Ankle movement and joint torque measured by position sensor and torque sensor, respectively.

People with brain injuries experience physical impairments and are usually examined by experienced clinicians to determine appropriate rehabilitation interventions. Clinicians use clinical scales to judge the severity of the impairments, and the consistency and reliability of those clinical scales are important for accurate rehabilitation and better healthcare services for patients. This article presents a manual spasticity evaluator (MSE) that measures joint range of motion, joint resistance, and stiffness at a controlled speed so that clinicians can use it conveniently in a clinical setting. The MSE was tested with children with cerebral palsy (CP) to measure joint range of motion, stiffness, and catch angle of spastic ankle joints, but it can be used for adults with neurological disorders including stroke, traumatic brain injury, spinal cord injury, and CP.
