The correlation between expressive language delay in children and their motor abilitiesCunningham, Gail G. 01 January 1983 (has links)
The purpose of the present study was to determine the correlation between expressive language delay in children and their gross and fine motor skills. Twenty children five years through six years, eleven months with a diagnosed expressive language delay, were selected to participate in the study. Each was screened on the basis of normal hearing, receptive vocabulary skills, motor functioning, and an expressive language delay of one year or more. After screening procedures, each child was administered the Preschool Language Scale-PLS (Zimmerman, et al., 1969) and the short form of the Bruininks-Oseretsky Test of Motor Proficiency-BOMP (Bruininks, 1978). The data were analyzed using a Pearson Product-Moment Correlation along with means, standard deviations, and a one-tailed t-test of significance.

Kinematic and Kinetic Differences and Asymmetries in Gait in Children with Adolescent Idiopathic ScoliosisGariepy, Catherine 01 January 2009 (has links) (PDF)
Adolescent idiopathic scoliosis (AIS) is characterized by a three-dimensional curve within the spine thus creating asymmetries within the trunk. In addition to modifying the trunk geometry, these structural asymmetries change the location of the center of mass. Gait patterns in people with AIS may possibly be altered on the basis of these structural changes. The purpose of this study was to identify differences in gait kinematics and kinetics as well as left-right symmetry as a function of the severity of adolescent idiopathic scoliosis. Forty-five girls divided into a control group, a mild-to-moderate AIS group and a severe AIS group participated in data collection. Gait analysis included bilateral kinematic and kinetic measurements. The maximal joint ranges of motion at the ankle, knee, hip and trunk-pelvis were analyzed. Maxima and minima in the antero-posterior, medio-lateral and vertical components of ground reaction force (GRF) were compared between the three groups as well as the median frequencies obtained from a frequency spectrum analysis of GRF. A symmetry index was computed between the primary curve side and the contralateral side for each kinematic and kinetic variable. Both AIS groups differed from controls in their range of motion at the ankle and at the knee but for the AIS group with severe curves, this was also observed at the hip. Both local maxima in the vertical component and the maximum of the antero-posterior component of the ground reaction force were decreased while the local minimum of the vertical component and the antero-posterior component of GRF increased in the severe AIS group compared to the control group. Higher median frequency contents in the antero-posterior and vertical component of ground reaction force were found in the AIS groups than in controls. No difference in asymmetry was found in any of the variables between all groups. These results seem to indicate that severe AIS participants have a more altered gait pattern than the mild-to-moderate AIS group. Findings from this study point toward greater changes in kinematics and kinetics during stance between all AIS groups and the control group.

ADAPTATIONS TO THE FOOT PLACEMENT STRATEGY WHILE WALKING THROUGH CLUTTERED ENVIRONMENTSAshwini Kulkarni (11984720) 07 August 2023 (has links)
<p> A key mechanism to maintain balance during walking is the foot placement strategy, where the person steps in the direction of an impending fall. On a clear walkway, the foot placement strategy translates to maintaining a consistent relationship between the center of mass state and the base of support (a body-centric constraint on foot placement), which is reflected in a consistent step length. However, to safely navigate in the community, foot placement must maintain certain spatial relations with environmental features as well (environmental constraints on foot placement). For stepping over obstacles, the environmental constraint takes the form of targeting. That is, the feet must be placed at precise locations relative to the obstacle to minimize the likelihood of tripping. My dissertation focused on proactive adaptations to foot placements while navigating cluttered environments. I developed the interstep covariation (ISC) index that quantifies the covariation between consecutive foot placements relative to stationary, visible environmental features (an obstacle and a visual target). The across-step (or group) changes in this index indicate how the two constraints (body-centric and environmental) on foot placement are managed during adaptive gait tasks. I quantified how the ISC index changed (1) across steps while approaching and crossing an obstacle, (2) due to healthy aging and (3) when the proximity of two environmental features was systematically altered. Specifically, in Study 1, the ISC index was quantified for the obstacle crossing step for healthy younger and older adults. In Study 2, proactive changes in the ISC index as healthy young adults approached and crossed an obstacle were characterized. In Study 3, the changes in the dynamics of the across-step ISC index due to an additional visual stepping target in the approach to the obstacle were identified. I found that there exists a covariance strategy that healthy adults use to navigate the environment safely and successfully. First, I found that individuals prioritize the environmental constraint at the expense of the body-centric constraint when the environment poses a larger risk to balance (the obstacle), or to satisfy a specified constraint (stepping on a visual target). Second, I found that the shift in prioritization is proactive, i.e., it occurs while approaching an obstacle. The strategy to shift priorities is influenced by age (Study 1), environmental features (Study 2 and Study 3), and the proximity of two environmental features (Study 3). These studies add to the current understanding of foot placement control by demonstrating how this well-known and 15 fundamental strategy to maintain balance while walking is systematically influenced by the environment and task constraints. These findings can be further extended to study proactive and reactive adaptations during walking in different populations. </p>
