The current major research focus in the lab is on patient handling. Healthcare providers report some of the largest musculoskeletal injury (MSI) rates and lost days on a yearly basis with most of the injuries being related to patient handling (repositioning, transferring from bed, toileting and bathing activities).

A series of projects are currently being conducted to understand: 

  1. The epidemiology of the healthcare challenge;
  2. quantifying the physical and biomechanical demand of specific patient handling techniques;
  3. the evaluation of technology and patient handling aids to reduces MSI;
  4. understanding the barriers and facilitators to implementing safe patient handling programs in acute and long-term care facilities; and
  5. determining the effect of training on patient handling adherence.

The average office worker spends 70% of their time sitting. This has led to a number office designs to help reduce the demands related to prolonged sitting, including active sitting.

An active chair allows the sitter to provide the action to move the chair, while the mechanism of the chair accommodates that action.

A series of research projects were undertaken to explore the physiological and biomechanical benefits of incorporating active seating at a computer workstation.

Active seating requires the user to ‘actively’ engage movement of a chair. An active seat with a split pan design allowed the user to actively peddle their feet while sitting allowing for increased blood flow to the legs.

Dr. Albert’s NSERC funded research has been focused on lifting, more specifically on the modifications to lifting technique related to prolonged lifting. To identify modifications a waveform analysis approach (Principal Component Analysis -PCA) has been used.

Work to date has focused on general fatigue modifications as well as modifications related to specific fatigue to the arms, back and legs, respectively.

Applied research associated with lifting and back loading has been involved with determining cumulative exposure on back loading during manufacturing activates and modifications to biomechanical demands when manual material handling activities are performed in moving environments (i.e., off-shore industry)

Occupations that involve vehicles as part of the workplace result in various ergonomic challenges. The Occupational Performance Lab has been involved in several projects focused on addressing ergonomic challenges.

The Lab has a VIRAGE full driving simulator that can simulate driving in car, trunk and ambulance as well as a separate chassis to simulate transport truck driving. We can assess urban and rural driving in various weather conditions. To date, the following projects have been undertaken:

Working with a NB company, the lab was involved in assessing the ergonomic design of secondary devices for use in driving.

Several designs that provided different options for control of secondary devices (i.e., horn, wiper, turn signals) were tested for both their ergonomic fit and their functionality (i.e., reaction time, error rates).

The secondary devices were installed with our driving simulator to assess driving errors when using the devices.
