PHTY203 Lecture Notes - Lecture 9: Cardiac Output, Insulin Resistance, Total Fertility Rate
Document Summary
List the sensori-motor changes that occur with normal aging. Intervention: use vision/glasses (corrective lens but care with multi-focals) Progressively manage b&m (graded practice: variable lighting/sunshine/shade, eyes open/eyes closed. Educate re limitations in variable environs: somatosensory system. Changes in the somatosensory system have also been identified including: jt positio(cid:374) se(cid:374)se (cid:894)i(cid:374)(cid:272)reased jpe(cid:895), passive movement sense, vi(cid:271)ratio(cid:374) se(cid:374)sitivit(cid:455) (cid:894)i(cid:374)(cid:272)reased threshold(cid:895, ta(cid:272)tile a(cid:272)uit(cid:455) (cid:894)larger (cid:373)o(cid:374)ofila(cid:373)e(cid:374)ts(cid:895) Initial significant decline for somato-sensory function occurs by 40s / 50s. 50% loss in 80-90s: the link between muscle retraining and potential cognitive benefits is an emerging. Strength is a major determinant of function: decreased strength results in, reduced ability to perform everyday tasks like standing up and walking. Increased risk of falling: research indicates aging has a relationship with lowered walking speed. It has also shown older people use significantly more of their available strength to rise from a chair: age-related changes in strength and somato-sensation during mid-life support rationale for targeted preventive intervention programs.
