Cerebral palsy (CP) is the most common children and adults movement disorder that is associated with life-long disability and multiple impairments. Children with CP demonstrate poor fine and gross motor function due to psychomotor disturbances. Early rehabilitation programs are essential for children with CP and should be appropriate for the age and functional condition of the patients. Robot-assisted...
This paper presents the design of a table-top game supporting the treatment of children with Cerebral Palsy. The game was developed through a participatory design process involving therapists and children from the target user group. The game is implemented on top of a platform that supports the implementation of tangible user interfaces using sensing technology. We argue that physical interaction,...
This article discusses the results obtained by computing 4 different quantitative metrics for the assessment of the upper limb, using the elbow angle as the datum for the experiment. This angle was obtained from a commercial Motion Tracking system with 19 subjects: 10 with cerebral palsy (CP) and 9 with no neurological impairment. Subjects performed one task, consisting in reaching a small object...
3D motion analysis was applied to assess goal-directed arm movements in 15 children with cerebral palsy (CP) before and after four weeks of home training with low-cost motion interactive video games. The results indicated that the children improved movement precision when playing the virtual games, improved movement smoothness when reaching for real targets, and reduced the involvement of the trunk...
Crouch gait, one of the most common gait pathologies among cerebral palsy (CP) is characterized by excessive knee flexion during stance phase that worsens over time and decreasing walking efficiency. CP patients in jump-knee gait have similar features to the individuals in crouch gait but exhibit a normal knee moment during midstance. Oxygen cost is the most reliable oxygen expenditure measurement...
This paper describes a video game for the rehabilitation of the pronation and supination movements of children with cerebral palsy. It is used as an interface for a robot that is currently under development. The game was programmed in LabVIEW and MATLAB is used for analyzing the results. It simulates a formula one racecar on a racetrack. Its objective is to keep the car inside the racetrack's limits...
This paper will describe the NJIT-RAVR system, which combines adaptive robotics with complex VR simulations for the rehabilitation of upper extremity impairments and function in children with CP. The feasibility of this system is examined in the context of two pilot studies. The NJIT-RAVR system consists of the Haptic Master, a 6 degrees of freedom, admittance controlled robot and a suite of rehabilitation...
We have developed a vector Doppler ultrasound imaging method to directly quantify the magnitude and direction of muscle and tendon velocities during movement. The goal of this study was to evaluate the feasibility of using vector Tissue Doppler Imaging (vTDI) for estimating the tibialis anterior tendon velocities during dorsiflexion in children with cerebral palsy who have foot drop. Our preliminary...
In this paper a new vision based interface (VBI) for children with cerebral palsy is presented. The VBI is implemented for the interaction between children and computer. The VBI detects and tracks the movement of the hand, foot or head of the user. These movements are translated into movements of the cursor on the screen of the computer. The evaluation of system user-VBI is based on HAAT model. The...
Children with cerebral palsy may have difficulty walking and may fall frequently, resulting in a decrease in their participation in school and community activities. It is desirable to assess the effectiveness of mobility therapies for these children on their functioning during everyday living. Over 50 hours of tri-axial accelerometer and digital video recordings from 35 children with cerebral palsy...
Cerebral palsy is a non-progressive neurological disorder caused by disturbances to the developing brain. Physical and occupational therapy, if started at a young age, can help minimizing complications such as joint contractures, and can improve limb range of motion and coordination. While current forms of therapy for children with cerebral palsy are effective in minimizing symptoms, many children...
The current study introduces a novel rehabilitation robot for treatment of impaired ankle in children with cerebral palsy (CP). The treatment consisted of passive stretching under intelligent control and active movement training with motivating game-playing using the portable robot. After 18 sessions of training (3 sessions/week for 6 weeks), we found significant improvement in 12 children with CP...
As part of a larger study evaluating the effects of trunk restraint on the kinematics of arm movements in children with cerebral palsy (CP), we evaluated the level of cooperation and satisfaction of the children when practicing arm and hand movements during play-like activities in a physical environment (PE) compared to a video-capture based (IREX, GestureTek) virtual environment (VE) using 5-point...
This paper will describe the NJIT-RAVR system, which combines adaptive robotics with complex VR simulations for the rehabilitation of upper extremity impairments and function in children with CP. The feasibility of this system is examined in the context of two pilot studies. The NJIT-RAVR system consists of the Haptic Master, a 6 degrees of freedom, admittance controlled robot and a suite of rehabilitation...
Virtual reality enables dynamic interaction between children and their environments, and active engagement in functional activities using a highly motivating, user-friendly and safe interface. The present work describes a new virtual environment, the Meal-Maker, created to evaluate and treat functional performance in a familiar context (kitchen) for children with cerebral palsy.
Virtual reality is a recent technology incorporated in upper extremity therapy programs for children with cerebral palsy. However, the systems currently being used cannot be graded to meet the skill level of children with cerebral palsy who have severely impaired upper extremities. These systems are often expensive, making them impractical for the clinical and home settings. ldquoHands-Uprdquo was...
Virtual environments can make repetitive motor rehabilitation exercises more motivating and thereby more effective. We hypothesize that participation-dependent multimodal stimuli increase the patientpsilas activity as expressed through force exertion during robot-aided treadmill training. In a single case study with one patient (12 years old), we were able to show that active participation increased...
This study applies an upper extremity model to analyze motion in 25 children with cerebral palsy using posterior walkers. The study indicates that throughout a gait cycle, the shoulders and wrist are in extension and the elbows are flexed. It also reveals that the elbows are the most asymmetrical joint of the upper extremities during walker-assisted ambulation.
Spastic hypertonia involving spasticity and/or contracture is a major source of disability in cerebral palsy and other neurological impairments like stroke. Several measures have been used to assess the reflex hyperexcitability and hypertonus associated with spasticity, including the Ashworth scale, tendon reflex scale, pendulum test, mechanical perturbations and passive joint ROM. These measures...
