Muscle reaction time was monitored during this study using Biometrics Ltd EMG sensors connected to the DataLINK unit. Study participants were instructed to stand barefoot on two platforms, one of which moves to simulate ankle sprain, EMG sensors were attached to the lower limb to document the muscle reaction time. A wet ice treatment was applied midway through data acquisition to confirm if this 'ice application'? effects the time taken for each of the three muscles studied to react thus affecting the performance/risk of injury of the athlete/subject.

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.
