“…The video recorded images of the participants entering and exiting the vehicles were then viewed and categorized into five main ingress and three main egress patterns, as per those identified and named by Menceur et al (2009) with the aim of determining if there were differences between healthy older drivers and those with mobility impairments according to specific vehicle models.…”

“…A series of investigations focusing on older occupants (Vrkljan et al, 2010;Zhan, Porter, Polgar, & Vrkljan, 2013) suggested that problems with accessibility (e.g., getting in/out of vehicle, storage/trunk space), visibility (e.g., mirrors, instrumentation displays, exterior of vehicle), and adjustability (e.g., steering, seat, brake/gas pedals) were identified as key areas for consideration for automotive design. Studies of vehicle accessibility in older adulthood have identified specific ingress and egress strategies employed by older adults with certain mobility impairments (e.g., hip or knee prostheses) (Ait El Menceur et al, 2009;Chateauroux & Wang, 2010). Hence, an important next step in this research is to examine the relationship between functional abilities (i.e., balance, mobility level, balance confidence, fall history) and how older adults actually interface when entering and exiting an automobile.…”

Vehicle designs that enhance the safety of older users should consider their needs in the design process. This study aimed to capture the ingress and egress strategies employed by older drivers in order to understand the relationship between balance and mobility and movement patterns. A sample of healthy older drivers (n=15; aged 72.5±7.9) and those with mobility impairments (n=17; aged 71.3±6.0) were captured entering and exiting four vehicle models using an adjustable vehicle mock-up. As well, semi-structured interviews and ride-a-longs were conducted with a sub-group (n=7) of participants with mobility impairments in order to explore how bodily changes associated with aging impact vehicle usability. There were no significant differences across vehicle models in terms of ingress, but there were with egress. Particular movement strategies used by both groups are discussed with regard to safety. Through this movement analyses, such evidence can be used to develop innovations that inform the next generation of vehicles that consider the needs of older users.

“…While the interest of the automobile industry in the ergonomical development of vehicles is increasing, biomechanical studies tend to focus on the implications of human motion in vehicle design (Giacomin and Quattrocolo 1997 ; Andreoni et al 2002 ; Lempereur et al 2005 ; Reed and Huang 2008 ; El Menceur et al 2008 ; Chateauroux and Wang 2010 ). Whilst the comfort and safety of elderly passengers are often addressed and suggestions are offered to enhance their convenience (Petzäll 1995 ), populations with prostheses are frequently excluded (El Menceur et al 2009 ). However, older people, predominantly those reporting osteoarthritis (OA) of the lower limbs, often experience significantly more problems than younger adults, when embarking and disembarking of a car (Herriotts 2005 ).…”

“…Researchers customarily restrict the movements and habits of the studied population in order to facilitate analysis and allow the comparison of the generated measures: that is, fixing the treadmill’s walking speed (Vogt and Banzer 1999 ), using chairs without armrests (Farquhar et al 2009 ; Abujaber et al 2015 ) and staircases without bannisters (Catani et al 2003 ), dictating the starting position (Spyropoulos et al 2013 ; Abujaber et al 2015 ), etc. Nonetheless, vehicle ingress strategies have been shown to feature great diversity in how individuals manoeuvre to get into a car (El Menceur et al 2009 ). Thus, restraining the interaction of a subject with the elements of the vehicle may ultimately defeat the purpose of the analysis.…”

Background: Post-operative performance of knee bearings is typically assessed in activities of daily living by means of motion capture. Biomechanical studies predominantly explore common tasks such as walking, standing and stair climbing, while overlooking equally demanding activities such as embarking a vehicle. Aims: The aim of this work is to evaluate changes in the movement habits of patients after total knee arthroplasty surgery in comparison to healthy age-matched control participants. Methods: A mock-up car was fabricated based on the architecture of a common vehicle. Ten control participants and 10 patients with severe osteoarthritis of the knee attended a single-and three-motion capture session(s), respectively. Participants were asked to enter the car and sit comfortably adopting a driving position. Three trials per session were used for the identification of movement strategies by means of hierarchical clustering. Task completion time was also measured. Results: Patients' movement behaviour didn't change significantly following total knee arthroplasty surgery. Control participants favoured different movement strategies compared to patients post-operatively. Group membership, height and sidedness of the affected joint were found to be non-significant in task completion time. Conclusion: This study describes an alternative movement identification technique for the analysis of the ingress movement that may be used to clinically assess knee bearings and aid in movement simulations and vehicle design.

“…27,28 Clustering has been used in a wide range of applications, from the mapping of the brain activity 29 to discovering patterns from stock markets 30 and earthquake applications. 31 [32][33][34] This paper explores the use of hierarchical clustering to classify the sit-to-walk movement and detect asymmetries in the movements of people with and without physical disabilities of the lower limbs. Even though trials are grouped through the clustering process, the movement strategy prescribed to each cluster needs to be identified through observation.…”
