Differences in muscle activation patterns during sit to stand task among subjects with and without intellectual disability.

Cuesta-Vargas AI, González-Sánchez M - Biomed Res Int (2013)

Bottom Line: The means of the basic features in both groups were 22.13 and 22.83 for age, 66.38 and 67.67 for weight, and 173.38 and 174.33 for height, for the ID (n = 8) and without ID (n = 7) groups, respectively.Each subject performed three sets of five repetitions during which, starting from sitting, they had to get up and sit on the chair.The results showed differences in the pattern of muscle activity between groups during sitting to standing movement.

ABSTRACT
The aim of this study is to analyse the differences in muscle activity between subjects who have intellectual disability and healthy subjects when they make the transition from sitting to standing positions. A cross-sectional study. A group of adults was divided into two subgroups: with and without intellectual disability (ID). The means of the basic features in both groups were 22.13 and 22.83 for age, 66.38 and 67.67 for weight, and 173.38 and 174.33 for height, for the ID (n = 8) and without ID (n = 7) groups, respectively. Each subject performed three sets of five repetitions during which, starting from sitting, they had to get up and sit on the chair. The recording of muscle activity was performed using surface electromyography taking the measures of muscle activity of different muscles of the lower limbs. The results showed differences in the pattern of muscle activity between groups during sitting to standing movement.

Mentions: On each muscle three electrodes were placed using a circular adhesive Ag-AgCl in the right hemisphere of each participant at a distance of two inches between them. To encourage the proper adhesion of the electrodes to each participant, body hair was removed using an electric razor, and to minimise skin resistance the area was washed with alcohol [37] (SENIAM). Figure 1 shows a schematic of the positioning of each of the electrodes in the different muscles studied.
