Standing up from a supine position is important for physical independence. This study was designed to describe movements within specific body regions used to stand up from a supine position. Another purpose was to identify motor developmental sequences for the upper extremities, lower extremities, and axial region for this rising task. Thirty-two young(More)
PURPOSE Investigating gait characteristics during the early stages of walking in CP may contribute to the understanding of the development of impaired gait. The objective of this study was to investigate differences in the variability and symmetry of spatiotemporal gait characteristics during the early years of walking in children with bilateral spastic CP(More)
Physical therapists frequently evaluate and teach patients to roll from a supine to a prone position. The purposes of this study were 1) to describe the rolling movements of adults and 2) to determine whether the movement patterns used to roll might represent different developmental steps within three body regions. Thirty-six healthy adult subjects were(More)
BACKGROUND AND PURPOSE Rising from the floor to a standing position is an important milestone in the development of children. The purposes of this study were (1) to describe the movement patterns (MPs) toddlers use when rising to a standing position, (2) to determine whether toddlers' MPs differ with age, and (3) to investigate whether MPs that are proposed(More)
From the time upright locomotor ability is acquired until the end of the human life span, standing up from the floor is a skill important to a person's physical independence. This study was designed 1) to determine whether within the rising task the movement patterns of different regions of the body vary with age and 2) to describe movements used by(More)
BACKGROUND AND PURPOSE The purposes of this study were to describe the movement patterns of middle-aged adults when rising from a bed and to determine whether there are age-related differences in movement patterns across the third through fifth decades of age. SUBJECTS Ninety-three adults (30 men, 63 women), ranging in age from 30 to 59 years,(More)
BACKGROUND Poor control of postural muscles is a primary impairment in people with cerebral palsy (CP). OBJECTIVE The purpose of this study was to investigate differences in the timing characteristics of trunk and hip muscle activity during walking in young children with CP compared with children with typical development (TD). METHODS Thirty-one(More)
Poor control of postural muscles is a primary impairment in cerebral palsy (CP), yet core trunk and hip muscle activity has not been thoroughly investigated. Frequency analysis of electromyographic (EMG) signals provides insight about the intensity and pattern of muscle activation, correlates with functional measures in CP, and is sensitive to change after(More)
