Improving hand function after stroke

RESEARCH STUDY

Stroke often affects both our ability of our hands to feel and our ability to contract muscles. Sensory and motor functions are tightly linked. Yet, most rehabilitation strategies aimed at regaining dexterity after stroke largely focus only on motor recovery.

We have previously found that some stroke patients have a disorganised touch perception map. When a patient is touched in one location on the hand while their eyes are closed, they feel it in some other location.  There is little awareness of this condition, and it is generally not detected during routine neurological examination as even patients themselves are not aware of it.

Our recent study revealed that it is possible to correct this scrambled map, leading to improved motor functioning. This new evidence means that we can now focus on creating new rehabilitation strategies that can help patients to regain normal sensation and fine motor skill after a stroke.

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.
