Balance, Dementia, Fine Motor Function, Gait, Muscle Tone, Paratonia
Conditions
Brief summary
The purpose of this study was (1) to investigate changes in gait, balance, fine motor function, and muscle tone, and (2) to find out if there is a correlation between muscle tone/presence of paratonia and motor function (gross and fine) in mild and moderate dementia.Three groups of participants were included in the study: healthy elderly (n=60), participants with mild dementia (n=31) and participants with moderate dementia (n=31). Measurements of fine motor function, balance, gait, presence of paratonia and muscle tone measurements were performed.
Interventions
assessment of fine motor skills with Purdue Pegboard, with dominant hand, non-dominant hand and bimanual
diagnosis of paratonia based on passive movement of the four limbs
MyotonPRO measurement of muscle tone
accelerometric assessment of gait (Dynaport Hybrid): 7m walk in 3 conditions (normal pace, fast, double task)
accelerometric assessment of balance (Dynaport Hybrid) during 10 seconds trial in 3 conditions (side-by-side, semitandem, tandem)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| MyotonPRO measurement of muscle tone | through study completion, an average of 3 years | MyotonPRO measurement |
| Fine motor function | through study completion, an average of 3 years | score on the Purdue pegboard test, maximal amount of (pairs of) pegs placed in 30 seconds (max. 25) |
| presence of paratonia | through study completion, an average of 3 years | Paratonia Assessment Instrument, resistance against passive movements of the four limbs is evaluated (Hobbelen 2008) |
| walking speed | through study completion, an average of 3 years | gait speed parameter |
| step regularity | through study completion, an average of 3 years | gait parameter representing regularity, autocorrelation (method Moe-Nilssen 2004), value between 0 and 1, with 1 representing perfect regularity |
| mediolateral jerk | through study completion, an average of 3 years | balance smoothness and coordination, lower jerk values correspond with better smoothness of balance |
| anteroposterior jerk | through study completion, an average of 3 years | balance smoothness and coordination, lower jerk values correspond with better smoothness of balance |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| MyotonPRO measurement of elasticity | through study completion, an average of 3 years | MyotonPRO measurement |
| MyotonPRO measurement of mechanical stiffness | through study completion, an average of 3 years | MyotonPRO measurement |
