A Systematic Review Of The Impact Of Powered Mobility Devices On Older Adults’ Activity Engagement, R Formiatti, L Moir, Janet Richmond, J Millsteed

Janet E Richmond PhD

Purpose: To systematically review the impact powered mobility devices have on engagement in independent occupations for adults with acquired mobility limitations. Method: Electronic search of CINAHL Plus, Medline, PsychInfo, OT Seeker, Joanna Briggs Institute, and Physiotherapy Evidence Database. Search terms included combinations of words to encompass all terms most likely used for powered mobility. Results: Eleven studies were eligible for inclusion. One study was a true experimental design; four studies were pre-experimental, and six were nonexperimental. Studies indicated positive improvements to occupational engagement and independence while environmental barriers were identified as negatively impacting occupation and increasing risk of injury or …

This study investigated mechanisms for the stressor-induced changes in muscle fatigability in men and women. Participants performed an isometric-fatiguing contraction at 20% maximal voluntary contraction (MVC) until failure with the elbow flexor muscles. Study one (n = 55; 29 women) involved two experimental sessions: 1) a high-stressor session that required a difficult mental-math task before and during a fatiguing contraction and 2) a control session with no mental math. For some participants (n = 28; 14 women), cortical stimulation was used to examine mechanisms that contributed to muscle fatigability during the high-stressor and control sessions. Study two (n = 23; …

Neck Muscle Fatigue And Postural Control In Patients With Whiplash Injury, Paul Stapley, Maria Beretta, Elena Toffola, Marco Schieppati

Objectives: To examine if patients with whiplash injury show identifiable increases in neck muscle fatigability and associated increase in postural body sway after contractions of dorsal neck muscles, and if physiotherapy treatment reduces these effects. Methods: Sway was measured during stance in 13 patients before and after 5 min of isometric dorsal neck muscle contractions and after recovery, pre- and post-physiotherapy, using a force platform. Amplitude and median frequency of neck muscle EMG were calculated during the contracting period. After each stance trial, patients gave a subjective score of sway. Results: Pre-treatment, seven patients showed EMG signs of fatigue (increases …
