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.

The purpose of this study was to establish the concurrent validity and test-retest reliability of the Biometrics electronic Dynamometer, and compare it with the criterion standard hydraulic Jamar dynamometer for measurement of grip strength among healthy participants. Conclusions in the results discussion include: "The concurrent validity between the Biometrics and Jamar Dynamometers was found to be excellent for both the right (0.986) and left hands (0.983),and indicates that both the Jamar and Biometrics dynamometers measure the same construct of grip strength. Results also indicate that the Biometrics Dynamometer is a valid tool for measuring grip strength." and "Electronic Dynamometers also have increased sensitivity to applied force, which therefore enables electronic Dynamometers, such as the Biometrics to record low grip strength that may not have registered on the Jamar." The Practical implications state: "This study has established that the Biometrics E-LINK evaluation system is a valid and reliable measurement tool to use by rehabilitation professionals."

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.

A Biometrics Ltd Dynamometer was used to measure the test-retest reliability of one vs. three trials. The Implications for Practice included: "The results of this study demonstrate levels of test-retest reliability (ICC -0.91) for the evaluation of one and the mean of three trials of pain-free grip strength tested using the Biometrics E-LINK evaluation system in participants with RA....A change in grip strength as small as 1.6 kg may be indicative of meaningful clinical change in RA patients; therefore, grip should be evaluated with an instrument with adequate sensitivity to detect this magnitude of change."

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.

Pre and post treatment functional evaluation was conducted using Biometrics E-LINK computerized Evaluation System. Tests performed included: range of motion measured using E-LINK electrogoniometers, pinch & grip strength measured using E-LINK electronic Dynamometer & Pinchmeter, documentation of manually collected data in E-LINK Evaluation software. The results of this study to evaluate the application effects of pulsed magnetic fields in rehabilitation were assessed by calculating the difference of the global impairment score, expressed in percentages, as calculated by the E-LINK software.
