The objective of this pilot study was to develop a method of evaluating incline manual wheelchair propulsion using optical motion capture, surface EMG and pushrim force. EMG data was collected using Biometrics DataLOG EMG system.
This study compared Biometrics Ltd DataLITE Wireless goniometers, IMU (inertial measurement units) and video motion capture for repeatability of measuring knee flexion angles. The electro-goniometer was observed to be more repeatable than the IMUs in this experiment.

This project compared conventional needles with needleless injectors in terms of cost, productivity, injury rates, biomechanical exposures, and worker preferrences. Biometrics Ltd DataLOG and EMG sensors were used to maesure hand/wrist muscle activity on swine workers performing injection tasks with both injection methods. Data was collected for several hours over two days.

This study aims to identify the impact that age has on muscle control and fatigue. Each subject is instructed to follow the activity protocol using the modifie4d apparatus, a Biometrics Goniometer is placed on the ankle and this is connected to the DataLINK unit. Ankle Goniometer data is useful to determine each participant range of motion during exercise which will confirm their fatigue response, data is compared between older and younger subjects and discussed.

This study focuses on analysing and comparing gait data amongst infant subjects and adult subjects. Biometrics Ltd Goniometers are positioned over the knee and hip joints of the subjects before they are instructed to complete the gait activities. Results are presented and discussed to conclude the differences and similarities between human adult locomotion, human infant locomotion and the locomotion of a selection of quadrupedal animals.

Biometrics Ltd Goniometers are applied to the wrist, elbow and shoulder of subjects a Torsiometer is also positioned over the wrist joint. Each subject is instructed to follow a set of instructions which include writing/drawing on a platform set to determined angles. Goniometer data along with other measured parameters is collected and analysed to better understand the upper limb movement in patients suffering from writer?s cramp.

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.

Biometrics Ltd Goniometers are used to verify the knee, hip and ankle joint throughout the duration of this Gait Analysis study. Goniometer data is collected and presented as a statistical comparison to determine the gait response when cutaneous electrical stimulation is applied to five foot muscles.

Two Biometrics Ltd Goniometers are used per subject during this study; Goniometers are connected to the Biometrics DataLOG. The posture of participants within this study is monitored; both the spinal joint angles (two spinal locations) and pain scores are used to determine the long term effects of sitting at a computer/desk within an office environment.

This frailty study relied on acquisition of quantified EMG measurements recorded over a significant time period (9/10 hour). Biometrics Ltd EMG sensors connected to the DataLOG unit allowed each study participant to freely go about their regular day while EMG data from their upper and lower limbs was collected and stored within the DataLOG unit (save to card mode). Data was analysed post data acquisition and combined with other quantified parameters to discuss the relationship between muscle activity and frailty category.

Biometrics Ltd Goniometers are applied to the wrists of study participants, all subjects are regular computer users. Goniometer data collected is used in combination with MRI data in order to document the effects of long term computer use on the wrist. A sub analysis included splitting subjects into either an asymptomatic or symptomatic group.

This comparative study utilises Biometrics Ltd EMG sensors connected to the DataLOG unit, EMG sensors are placed on the forearms of participants during the activity/data acquisition stage. All EMG data collected is presented in order to discuss the comparisons between two safety techniques used in the building and construction industry for ladder climbing. Participants wore the DataLOG unit on a belt around their waist as they climbed ladders using each safety device.

Biometrics Ltd EMG sensors were used in this study in order to compare muscle activity between two sanding techniques. The EMG sensors were connected to the Biometrics Ltd DataLOG unit and data was analysed post acquisition. Findings from this study are useful to the building and construction industry as they highlight some egronomical limitations of new techniques/equipment.

This visual-spatial experiment includes the use of Biometrics EMG sensors connected to the DataLINK unit. Subjects are monitored as they undertake a biofeedback 'game' in which their ability to maintain balance is analysed. EMG data collected is filtered and displayed alongside the centre of foot pressure (COP) results to determine an individuals' response to different Motor tasks.
