The Biometrics Ltd Dynamometer is used to determine the Grip Strength of subjects suffering from Arthritis. The Grip Strength data is presented together with the outcomes of the new hand function test designed specifically for people with arthritis, the Grip Strength data is also applied to the final analysis showing test-retest reliability.

This grip analysis study documents a relationship between age and effects of medication within a group of patients suffering from Parkinson's disease. Each subject is instructed to grip (using the Biometrics Ltd Dynamometer) after an LED cue. Age matched healthy (non-Parkinson's disease) subjects are included as a control group. Multiple force parameters are documented including time delay (from cue to grip) and grip strength over the experimental period.

This crosstalk analysis utilises the Biometrics Ltd Surface EMG sensors connected to the DataLINK unit. Subjects were measured and EMG sensors were applied to specific points of their forearms, EMG data was then recorded during static grip exercises. Post data acquisition filtering is applied to the EMG data to present the effects of crosstalk.

Participants of this study had recently undergone carpal tunnel surgery. The analysis aims to investigate the results from a patient questionnaire with quantitative data recorded. The Biometrics Ltd dynamometer connected to the DataLINK unit was used to record grip strength for the subject population pre and post-surgery.

A variety of Biometrics Ltd sensors are used to measure arm function and spasticity in stroke patients. Sensors used include the Dynamometer, EMG probes, Goniometers and a custom built, hand held force transducer all connected to the Biometrics Ltd DataLINK unit. Data was recorded at distinct time intervals post stroke in order to document arm function recovery of two control groups, one group were administered a low dose of botulinum toxin early on after stroke while the other was administered a placebo.
