Stroke & Older Adults

Tuesday, May 21, 13

Older Adults

Physiological systems decline with the advance of age, which can inhibit interaction with technology and other functions of everyday life. Some of the major areas of decline are with the cognitive suite and motor function. Affects of these impairments can lead to disability with older individuals, and their capacity to care for themselves.

Tuesday, May 21, 13

Older Adults

Most of us will be considered disabled at some point in our lives.

• The Intrinsic Motivation Inventory (IMI) is a multidimensional measurement device intended to assess participants' subjective experience related to a target activity in laboratory experiments.

• The EMI consists of 23 statements divided into three sub-scores for physical, psychological and social motivation.

Tuesday, May 21, 13

Findings

•Older adults have a vast range of physical capabilities and attention spans

•Do not under-estimate the abilities of older users, but do allow configuration and customization of skill levels

Tuesday, May 21, 13

Findings

•Some older adults and stroke patients show great difficulty with the ballistic phase of touches

•Speech audio hindered, rather than helped the rehabilitation process
