Pedals cerebral palsy

Tobias Blumenstein, Hilar Zeitlmann, Ana Alves-Pinto, Varvara Turova, Renée Lampe
Cerebral palsy is a group of neurodevelopmental disorders that affect a person's ability to move and to maintain balance and posture. People with cerebral palsy have also perception and space orientation deficits so that special assistance devices should be developed to compensate these handicaps. The objective was to optimize an adapted electric bicycle (E-bike) for youths with neurodevelopmental disorders. An adapted E-bike was provided with ultrasonic sensors that measure distances to objects. If the distance to other objects reduces, an acoustic signal is sent...

AIM: The aim of this study was to assess health-related quality of life (HRQOL) following a stationary cycling intervention in children with cerebral palsy (CP). METHOD: This was a phase I multisite randomized controlled trial with single blinding. HRQOL was evaluated using the Pediatric Quality of Life Inventory SF15 (PedsQL; children) and Pediatric Outcomes Data Collection Instrument (PODCI; parent proxy) before and after a 3-month stationary cycling intervention...

BACKGROUND: Each of the 4 randomized clinical trials (RCTs) hosted by the Physical Therapy Clinical Research Network (PTClinResNet) targeted a different disability group (low back disorder in the Muscle-Specific Strength Training Effectiveness After Lumbar Microdiskectomy [MUSSEL] trial, chronic spinal cord injury in the Strengthening and Optimal Movements for Painful Shoulders in Chronic Spinal Cord Injury [STOMPS] trial, adult stroke in the Strength Training Effectiveness Post-Stroke [STEPS] trial, and pediatric cerebral palsy in the Pediatric Endurance and Limb Strengthening [PEDALS] trial for children with spastic diplegic cerebral palsy) and tested the effectiveness of a muscle-specific or functional activity-based intervention on primary outcomes that captured pain (STOMPS, MUSSEL) or locomotor function (STEPS, PEDALS)...

BACKGROUND: Effective interventions to improve and maintain strength (force-generating capacity) and endurance are needed for children with cerebral palsy (CP). OBJECTIVE: This study was performed to examine the effects of a stationary cycling intervention on muscle strength, locomotor endurance, preferred walking speed, and gross motor function in children with spastic diplegic CP. DESIGN: This was a phase I randomized controlled trial with single blinding...

BACKGROUND: We showed that subjects with cerebral palsy had greater transverse and frontal plane hip and knee motion, increased duration of muscle activity, increased cocontraction, and decreased efficiency during recumbent cycling than subjects with typical development. However, it is also important to understand the forces exerted on the pedals. The purpose of this report was to compare pedal forces during cycling between adolescents with and without cerebral palsy. METHODS: Ten subjects (3 male, 7 female) with spastic diplegic or quadriplegic cerebral palsy (15...

This study investigated the effects of exercise on the motor function of 11 young people (10 females, one male; age range 11-15y; mean age 12y 7mo [SD 1y 4mo]) with cerebral palsy (CP) who were non-ambulant (Gross Motor Function Classification System Levels IV or V), using an adapted static bicycle. Three participants had dyskinetic quadriplegia, seven had spastic quadriplegia, had spastic quadriplegia, and one had spastic diplegia. The study used an ABA design with participants acting as their own controls with 6-week baseline, 6-week exercise (three sessions a week), and 6-week follow-up periods...

BACKGROUND AND PURPOSE: The purpose of this study was to compare the biomechanics of recumbent cycling between adolescents with cerebral palsy (CP) classified at Gross Motor Function Classification System (GMFCS) levels III and IV and adolescents with typical development (TD). SUBJECTS: Twenty subjects, ages (X+/-SD) 15.2+/-1.6 years (10 with TD, 10 with CP), participated. METHODS: Lower-extremity kinematics and muscle activity were measured at 30 and 60 rpm while subjects pedaled on a recumbent cycle...

BACKGROUND: In the past, effortful exercises were considered inappropriate for children with spastic cerebral palsy (CP) due to concern that they would escalate abnormalities including spasticity and abnormal movement patterns. Current scientific evidence indicates that these concerns were unfounded and that therapeutic interventions focused on muscle strengthening can lead to improved functional ability. However, few studies have examined the potential benefits of cardiorespiratory fitness exercises in this patient population...

Pedaling smoothness and electromyography patterns were quantified in children with spastic diplegic cerebral palsy (CP) and a cohort of children with typical development. Video analysis of the pedaling rhythm yielded equivalent time periods for the control group and irregular time periods in the group with CP, with greater time spent at the bottom of the pedaling cycle. Electromyography patterns of the tibialis anterior, rectus femoris, medial hamstring and lateral gastrocnemius muscle groups yielded greater percentages of muscle activity time and co-contraction time at both the ankle and knee in the group with CP; however, the control group had longer ankle co-contraction times than were expected from previous adult studies...

The purpose of this study was to design, construct, and validate an alternative subject/instrument interface to collect metabolic data for individuals who, because of impairment, are unable to use a mouthpiece. An industrial designer directed the development of an interface design which would facilitate subject acceptance. A total of 13 subjects (eight children with cerebral palsy and five nonneurologically impaired) participated in the validation study. Metabolic data were collected at rest and during three levels of exercise, using both the traditional mouthpiece and the interface designed for this study...

This study used a method specifically adapted to motor handicap, one which measured pedaling rate and basal oxygen consumption. Its aim was to investigate whether bicycle ergometer work could distinguish any difference in mechanical efficiency between two groups with cerebral palsy. 10 patients aged between 18 and 30 years (six dyskinetic/ataxic, four spastic) were studieed. Six non-handicapped young adults formed a control gorup. The results showed a highly significant difference between the dyskinetic/ataxic group and the spastic group...

Thirty-four spastic cerebral palsied (CP) post-poliomyelitic (P) adolescents (mean age--17.9 years) participated in a twice-a-week mild conditioning program, lasting 12 months. Nine CP adolescents served as a control inactive group. The post-conditioning submaximal heart rates of the CP active group were significantly lower during 75 and 150 kpm/min work loads on an arm ergometer, compared with the respective values at the beginning of the program. Peak O2 uptake values, directly measured during an all-out arm pedalling test, were improved by some 8% in the CP active group...
