Biometrics Ltd equipment is used to identify a relationship between upper limb functional recovery and the development of spasticity in stroke patients over a quantified time. A combination of Biometrics sensors including Goniometers and EMG probes were used along with a force transducer to evaluate range of motion muscle activity and force simultaneously during exercise. With this data, clinicians are capable of studying the development of spasticity and wrist contractures over time in addition to confirming the relationship between spasticity, function and contracture development.
