“…However, after 6 weeks of wearing the HPD, she was able to print her name and other letters legibly by using the HPD. Other preliminary work with the HPD (Reid & Sochaniwskyj, 1992) showed that 7 out of 10 children with cerebral palsy improved their scores on a visual-motor test battery made up of paper-pencil activities when wearing the HPD as compared to not wearing the device. This study was an attempt to examine the short-term effects of using an HPD on upper-extremity control in children with cerebral palsy.…”

This paper describes how to modify the quality of upper extremity reaching in children with cerebral palsy by using a hand positioning device. AbstractThe effects of a hand positioning device (HPD) on the quality of upperextremity movement offive children with cerebral palsy were examined in this pilot study. Hand position was monitored during a reaching task using a single-point, 3°-oJ-freedom, three-dimensional tracker device. Threedimensional path length, average velocity, movement time, response time, and the number of accelerations and decelerations (movement units) were measured. Operational definitions for each of these variables were developed for this study. Each subject performed 15 reaching trials at a pretest and posttest. A 6-week intervention period followed the pretest where each subject wore the HPD for 1 hour daily for junctional activities. Group results showed no significant differences for any of the variables being measured. However; individual data analysis reoealed that the HPD has Denise T. Reid, PhD. Of(q is on the Faculty

“…Some investigators used "movement element" or "movement unit" in the characterising of smoothness of spastic upper limb movement [6]- [8]. A "movement unit" was defined as one wave of acceleration or deceleration, with a threshold rate of change of speed to qualify as an acceleration or a decel- Fig.…”

“…Some researchers have used "movement element" [7], [10], and [11] or "movement unit" [6], [8], and [12] in the investigation of the reaching behavior of infants or spastic subjects. However, the number of "movement units" so defined depended on certain pre-set threshold amplitude of acceleration or deceleration and such objective threshold was often difficult to define.…”

The purpose of this study was to quantitatively compare the difference in voluntary upper extremity movements between subjects with and without spasticity. Eight normal subjects (mean 26.7 6 2.8 years, four males and four females) and seven subjects with spasticity (mean 25.9 6 4.3 years, three males and four females) were involved in this study. The subjects sat in an adjustable chair and performed two voluntary tasks involving the elbow joint. Task A was to move the hand between two touch-plates which were mounted 28 cm apart on the surface of the table. Task B was to flex and extend the elbow joint in the sagittal plane with the forearm in neutral position. Reflective markers were attached on the shoulder, the elbow and the wrist. A Peak5 video-based motion analysis system was used to record the positions of the markers in the three-dimensional (3-D) space during the movement tasks. A set of quantitative parameters were used to document the elbow movement. The results revealed that in comparison to normal subjects, subjects with spasticity exhibited a higher average jerk, a larger standard deviation of the coordinates of the markers along the movement path, a larger standard deviation of the angle between the plane of the elbow joint and the horizontal plane, and a longer 3-D path length. The characteristics of spastic elbow movement and the usage of quantitative parameters were discussed.
