Studies of voluntary and involuntary control of human breathing

WHAT WE KNOW

Breathing is a complex motor task that needs to be coordinated at all times while we eat, speak, exercise and even during sleep. The breathing muscles are controlled automatically from the brainstem during normal breathing but can also be controlled voluntarily from the motor cortex.

The way these two drives to the breathing muscles interact is still not well understood. While there is some evidence that there are at least two independent pathways, and that integration of the pathways occurs at the spinal cord, there is some uncertainty about whether these pathways may have some interaction in the brainstem.

Our overall goal is to determine the role of neural drive in impairments of respiratory muscle function in older adults (over 65 years), people with chronic obstructive pulmonary disease (COPD), spinal injury or obstructive sleep apnoea (OSA).

ReacStep – novel balance training programs to prevent falls in older adults

The ReacStep study is investigating the short-term effects of two balance training programs (i.e. reactive balance training and conventional balance training) on balance recovery from slips and trips in older adults. These programs are designed from evidence-based research and offer a challenging and unique experience to improving balance. The ReacStep team are calling on volunteers who: are aged 65 and over living independently in the Sydney metropolitan community can walk 500m comfortably with mobility aids or rest have not been advised by a medical practitioner not to exercise have no neurological conditions (e.g. Parkinson’s Disease, multiple sclerosis, Alzheimer’s, dementia, etc.) have no history or lower limb, pelvic or vertebral fracture(s) and/or lower limb joint replacement(s) in the past 6 months have no other existing conditions that may prevent them from exercising (e.g. injury, pain, fatigue, etc.) Eligible volunteers will be subjected to a health and safety screening before they are enrolled and randomly allocated into one of the two groups. Both groups will undertake a 3-week training program with an exercise physiologist, at NeuRA (i.e. in Randwick) as well as a balance recovery assessment at the 4-week time point. Reactive balance training involves intentionally stepping on a sliding tile, stepping over obstacles, trigger-release recovery as well as strength training. Participants will be wearing a full-body safety harness to ensure safety. Conventional balance training involves keeping balance in varying foot positions (i.e. feet together, in tandem or on one leg) whilst performing secondary tasks such as throwing a ball, card sorting, solving a maze or playing computer games.
