    Congruency and responsiveness of perceived exertion and task duration associated with an intermittent isometric fatigue task
    (Elsevier, 2021-11-21) Peer, M. A.; Gallacher, P. D.; Coutts, Fiona; Gleeson, Nigel
    Purpose: The shift away from supervised rehabilitation towards greater self-management requires that people are able to accurately self-monitor their exercise performance and exertion and apply appropriately dosed exercise to achieve optimal outcomes. An extended period of sub-optimal exercise may result in insufficient physiological stress to restore knee function and recovery to a level of PA similar to asymptomatic peers. Subsequently greater post-operative healthcare burdens may be imposed on limited NHS resources. It is currently unclear whether measures of exercise self-perception of exertional stress (CR-10 and perceived task duration [PTD]) demonstrate a similar pattern of change in a clinical population such as total knee arthroplasty (TKA) and thus, may be recommended as a scale for regulating exercise performance during resistance training. The aim was to enhance the understanding regarding whether people are able to accurately calibrate self-perceived exercise performance capability and perceptions of exertional stress. Further, this study intended to identify whether perceived exertion offers a precise reflection of task duration.

    Peri-surgical change in objective functional, neuromuscular and sensorimotor performance of people awaiting total knee arthroplasty
    (Elsevier, 2021-11-21) Peer, M. A.; Gallacher, P. D.; Coutts, Fiona; Gleeson, Nigel
    Purpose: Total knee replacement (TKA) surgery is acknowledged as an effective management option to reduce pain symptoms, improve perceived function and quality of life. Nevertheless, considerable impairment of physical function and aberrant neuromuscular alterations often persist following surgery intervention and the reason for this is unclear. Accordingly, there is a need to examine objectively peri-surgical performance capabilities and neurophysiological changes of this clinical population to optimise the constituents and dosages for effective exercise conditioning interventions. The aim of this study was to perform a single-leg contra-lateral control limb model to investigate peri-TKA surgery and conditioning-related changes in objective measures of physical function and neuromuscular and sensorimotor performance.
