Hand grip and malnutrition / How errors affect our movements
- Full Description:
- Two talks have been scheduled as part of the 2017 HMNS Seminar Series
Hand grip strength as an indicator of malnutrition in older patients before, during or after admission to surgical wards.
Hand grip strength (HGS) has been proposed as a surrogate measure of nutritional status that may be more sensitive to changes in nutrition-related muscle function than other body composition measures. This makes it particularly attractive for use in the acute setting. In this presentation, Angela Byrnes (PhD Candidate at HMNS) will provide an overview of results from a study that aimed to determine accuracy of HGS as an indicator of malnutrition in an older (≥65 years) population in the acute and outpatient setting.
How errors affect our movements.
In goal-directed reaching, we learn to flexibly adapt our behaviour to move in an ever-changing environment. Perturbations either at the moving effector, or in the environment we move in, induce errors in our predictions of the sensory outcomes of our movements, and errors in our predictions of the success of our movements.
In this seminar, Dr Li-Ann Leow (UQ Development Fellow at HMSN) will present a series of experiments which attempts to dissociate the role of these two types of errors when we adapt movements to perturbations.
