The advantages of this method are the following: (i) the height of the platform is far lower than that of the pole, and, therefore, mice are protected from injuring themselves; (ii) the uneven surface increases the difficulty of movement, thus making the differences in motor function more obvious.
A total of 80 dogs recruited from all parts of Norway, with pain and difficulty of movement due to canine hip dysplasia (CHD), were included in the study.
This process, which he called circumnutation has not received much attention, probably due to the difficulty of studying movement in soil.
As in so many things, Darwin anticipated important questions concerning the movement of plants, despite the difficulties in observing plant behavior, and in 1880 he published The Power of Movement in Plants.
Indeed, Flowers considered increased variability of movement in both time and space to be one of the core components of motor dysfunction in PD, along with a basic slowness of movement, and a difficulty in initiating and maintaining movement (Sheridan et al., 1987).
In each village, the headman was asked to list names of persons "having difficulty in movement" (in Isaan, pai sai ma sai yak).
Descriptions of shoulder kinematics during wheelchair propulsion are limited to motions of the upper arm due to the difficulty of measuring scapular movement in vivo.
Presenting the prevalence of movement difficulties in well-functioning preschool children based on quantitative test results has the following limitations.
Similarly, patients with depression exhibit difficulties initiating movements in the absence of external cues, as patients with Parkinson's disease.
Studies have shown that the M-ABC-2 is a reliable and valid tool for the assessment of movement difficulties, even in very young children (4 to 6 years of age) [ 31].
