Fine and Gross Motor Function and Relationship With Muscle Tone in Older Adults With and Without Dementia

walking speed

gait speed parameter

Time frame: through study completion, an average of 3 years

step regularity

gait parameter representing regularity, autocorrelation (method Moe-Nilssen 2004), value between 0 and 1, with 1 representing perfect regularity

Time frame: through study completion, an average of 3 years

mediolateral jerk

balance smoothness and coordination, lower jerk values correspond with better smoothness of balance

Time frame: through study completion, an average of 3 years

anteroposterior jerk

balance smoothness and coordination, lower jerk values correspond with better smoothness of balance

Time frame: through study completion, an average of 3 years

Fine motor function

score on the Purdue pegboard test, maximal amount of (pairs of) pegs placed in 30 seconds (max. 25)

Time frame: through study completion, an average of 3 years

presence of paratonia

Paratonia Assessment Instrument, resistance against passive movements of the four limbs is evaluated (Hobbelen 2008)

Time frame: through study completion, an average of 3 years
