We don’t normally have to think about our breathing and that’s because breathing is handled by a subconscious part of the brain called the medulla. The medulla automatically controls our breathing as well as our heart rate and blood pressure (Del Negro et al. 2018). It sends neural signals to the […]
Previous studies have shown that repeatedly working muscles until fatigue results in reduced strength, sensation, walking and balance control in older people (Helbostad et al. 2007, 2010; Kent-Braun, 2009; Pline et al. 2005). However, these extreme protocols are unlikely to accurately reflect an older person’s daily activities and likely miss the […]
Negotiating unexpected obstacles, such as cracks in pavement, requires successful adaptation of our walking pattern to guarantee stability and to avoid falling. Poor walking performance might contribute to tripping, which is frequently reported as a cause of falls in older people (Lord et al. 1993). We have devised a test […]
While older people most often fall because of a slip, trip or loss of balance, up to 25% of falls remain unexplained (Anpalahan & Gibson, 2012; Davies & Kenny, 1996; Lord et al., 1993). People who have had unexplained falls report having fallen because of a blackout, dizziness, feeling faint or “having […]
Balance exercise programs are an effective way to prevent falls in older people. Exercises are mostly focused on controlling the center of mass while reducing the base of support, for example by standing on one leg. Balance control however, also requires adaptive responses that would require a person to either […]
A progressive reduction in limb muscle mass is characteristic of advancing age, usually referred to as sarcopenia (Rosenberg, 1997). This loss of muscle mass and strength is likely to contribute to the general loss of mobility and risk of falling, a major concern for the elderly. These problems have been […]
In a recent interview, Simon Gandevia talks about a recently published review article by Stephen Lord, Kim Delbaere and himself which examined how motor impairments become more prevalent with ageing and how careful physiological measurement and appropriate interventions offer a way to maximise health across the life span. PUBLICATION: Lord SR, […]
Previous research had shown that when people are required to simultaneously perform a cognitive and balance task their performance is worsened in one or both tasks, and that this interference is even more marked in people with reduced sensorimotor and/or cognitive functioning due to age and disease [1-2]. Interestingly, it […]
Here’s why you should exercise, walk fast and plan for your retirement! Here we highlight some messages from 2014 from the Motor Impairment team. They focus on AGEING. In the coming days we will post additional highlights from 2014 dealing with other aspects of Motor Impairment and motor performance. Ageing […]
