Cerebral Palsy

The authors examined clinical outcome and cranial magnetic resonance imaging (MRI) findings in infants with hypoglycemia to determine the effects of hypoglycemia on the developing brain. A total of 110 infants with hypoglycemia were included in the study. Of the patients, 36 were females and 74 were males. The age of the infants was between 1 day and 22 months. Of the 110 infants, 47 were preterm neonates, 40 were term neonates, and 23 were older than 28 days. No difference in serum glucose level was noted between symptomatic and asymptomatic infants. The most common observed abnormal findings were hyperintense lesions, encephalomalacia, and cerebral atrophy. Abnormal MRI findings were found in 4% of preterm infants, in 32.5% of term infants, and in 43.5% of older infants. Abnormal MRI findings were statistically significantly more common in symptomatic infants than in asymptomatic infants. Of the infants, 45.5% of hypoglycemic infants had cerebral palsy and/or cerebral palsy plus epilepsy.

Biofeedback of muscle activity is commonly used as an adjunct to physical therapy, but it has not previously been used for long-term treatment of movement disorders. The authors hypothesized that chronic daily use of biofeedback of muscle electrical activity might promote improved use of the upper extremity in children with cerebral palsy and upper extremity motor deficits. They constructed a portable electromyography (EMG) unit that includes a surface EMG sensor and amplifier, microcontroller-based nonlinear signal processing, and vibration feedback of muscle activity. A total of 11 children ages 6 to 16 years, with cerebral palsy or acquired static brain injury, wore the device at least 5 hours per day for 1 month. Changes in upper extremity function were assessed using an individualized Goal Attainment Scale. Results showed significant clinical improvement in all 10 children who completed the study. These results suggest that further testing of prolonged surface EMG biofeedback is warranted.

Cerebral Palsy (CP) is a static disorder of movement and posture secondary to an insult to the developing central nervous system. The peripheral manifestations and functional impairments of this condition vary in severity from mild-to-profound. In hemiplegic CP, 1 side of the body is affected more than the other. Spastic hemiplegia is the most common type and that for which upper extremity surgery is most indicated. Treatment options range from physical therapy and splinting to botulinum toxin A injections (Botox) to tendon transfers to arthrodeses. This article will discuss the indications, preoperative evaluation, our preferred surgical technique, and postoperative protocol for the most commonly used tendon transfers in the upper extremity in spastic hemiplegia.

Wrist arthrodesis can obtain better appearance, hygiene, and ease of daily care, with some degree of functional improvement in patients with cerebral palsy with a severe wrist flexion deformity. Rigid fixation using a dorsal plate and screws has been accepted as a reliable technique, although hardware-related problems are relatively common. We describe a volar plate fixation technique for wrist arthodesis in cerebral palsy, which can allow concomitant flexor tendon release and avoid a prominent hardware and a cosmetically undesirable scar on the dorsum of the wrist.

Purpose. Postural management is used to help address the musculoskeletal and participation issues associated with cerebral palsy (CP). This study aimed to identify the factors influencing postural management in special schools. Method. A purpose-designed, cross-sectional, descriptive survey was sent to teachers, physiotherapists, occupational therapists and speech pathologists working with children with moderate-to-severe CP, aged 5-12 years, in special schools within South Australia. The instrument included four main areas: demographics, perceived benefits of postural management, factors facilitating or hindering the implementation of postural management programmes and suggestions for improvement. Results were analysed descriptively. Results. Forty-three therapists and 18 teachers completed the survey (response rate 81%). The most common factors hindering postural management were positioning equipment being unavailable or difficult to use, lack of time and school staff’s knowledge and skills to carry out postural management. Facilitating factors included therapy staff providing a written postural management programme, open and regular communication between therapy and school staff and timetabling of postural management into the daily routine. Conclusions. Numerous factors impact on postural management for students in special schools. Practical solutions highlighted were increased training for school staff, timetabling of postural management into students’ routines and provision of written postural management programmes.

OBJECTIVE: To assess participation and health-related quality of life in adults with bilateral spastic cerebral palsy, and explore associations with self-efficacy. DESIGN: Cross-sectional study. SUBJECTS: A sample of 56 adults with bilateral spastic cerebral palsy (mean age 36.4 (standard deviation 5.8) years; 62% male). METHODS: Daily activities and social participation (Life Habits 3.0), health-related quality of life (SF-36 Health Survey), demographic and clinical characteristics, and self-efficacy (General Self-Efficacy Scale (GSES-12)) were assessed. Associations were studied using multivariate logistic regression analyses. RESULTS: At least 60% of the sample had difficulties with mobility, recreation and housing, and 44% had difficulty with personal care and employment. They perceived low health-related quality of life for physical functions, but not for mental functions. Corrected for demographic and clinical characteristics, general self-efficacy explained 49% of the variance in outcome on social participation, and the subscale Effort (GSES-12) 32% of the variance for the physical health-related quality of life and 16% of the mental health-related quality of life. CONCLUSION: A significant number of adults with bilateral spastic cerebral palsy encountered difficulties in social participation and had a low perceived health-related quality of life for physical functions. Higher general self-efficacy or a greater willingness to expend effort in achieving behaviour was related to better participation and a higher physical and mental health-related quality of life.

This study aims to analyze the quality of life of mothers of children with cerebral palsy, correlated with the evolution of their children's gross motor function after ten months of rehabilitation. An observational, longitudinal study was carried out in Goiânia, Goiás, Brazil, involving 100 mothers and children with cerebral palsy. The children's motor function was evaluated using the Gross Motor Function Measure (GMFM) and the mothers' quality of life using the Medical Outcomes Study 36-item Short Form Health Survey (SF-36). After ten months of rehabilitation, the children's gross motor function had significantly improved (p<0.001), while the mothers only presented a significant improvement (p<0.001) in the bodily pain domain. The improvement in the motor function of children with cerebral palsy did not influence the changes in the mothers' quality of life.

AIM: This study is a report of a study describing mothers’ experience of learning that their child has been diagnosed with cerebral palsy. BACKGROUND: Learning a child’s diagnosis of disability is a crisis for parents. Their reactions include shock, refusal to accept the diagnosis, anger, fear, and uncertainty about the extent of disability and associated impairment. Knowledge about parental reactions is based on studies conducted in western countries, many of which do not apply to Taiwan where Confucianism strongly influences cultural perspectives of family and disability. METHOD: In this phenomenological study, data were collected in 2005-2006 using in-depth interviews and journaling with 15 Taiwanese mothers of children diagnosed with cerebral palsy. Hermeneutic analysis was undertaken of interview transcripts and journal notes. FINDINGS: Four shared meanings associated with learning of their child’s diagnosis were revealed: feeling out of control and powerless, mistrusting healthcare professionals, release and confirmation, and feeling blamed for not following traditional practices. Mothers experienced a loss of their ‘ideal’ child when their child was diagnosed with cerebral palsy. Expectations of ‘normal’ motherhood and fulfilling societal anticipation of giving birth to a healthy child were lost. Maintaining their husband’s family honour and prosperity, as well as saving face in their community were threatened. Mixed feelings of disbelief, rejection, self-blame and sadness were compounded by uncertainty about their child’s future. CONCLUSION: To promote better understanding of the child’s condition, emotional support and information should be provided to the mother and family, both when informing them of the diagnosis and in the period after diagnosis.

Abstract A case of spinal arterio-venous malformation (AVM) initially diagnosed as unilateral cerebral palsy (CP) is reported. The presentation was of a long-standing spastic monoparesis of the left leg, with initial response to Botulinum toxin injections to the calf and tibialis posterior muscles. This was followed by progressive deterioration occurring over a 3-month period before further investigation and definitive diagnosis at 7 years. Imaging demonstrated a large extra-medullary spinal AVM compressing the mid-thoracic cord. This was successfully managed by embolisation with a non-adhesive polymer: ethylene-vinyl alcohol copolymer injected into the dominant feeding vessel. This case highlights the need to consider alternative diagnoses when a child with a diagnosis of CP presents with atypical clinical features such as monoparesis and has worsening or altered clinical signs. Moreover, a normal magnetic resonance imaging brain scan and the absence of ipsilateral upper limb neurological signs or functional impairment should raise suspicion even in the context of static lower limb signs. A literature review was performed on the management of spinal AVM in children and this will be is discussed.

Failure of the knee extensor mechanism is a potentially disastrous complication of diplegic cerebral palsy and if left undiagnosed may lead to a cessation of independent walking. The disruption of the extensor mechanism usually occurs through or distal to the patella. The aim of this article is to describe the knee kinematic pattern associated with such knee pathology. We also present a mathematical model of knee crouch that leads to this problem. In a retrospective review of patients with radiographically proven disruption, we compared the postfailure clinical and kinematic data to premorbid data. All patients included in this study had attended our clinical Gait Analysis Laboratory on two occasions. In the patients with disruption of the extensor mechanism, the kinematic pattern changed from crouch with shock absorption to one of increased crouch and loss of shock absorption. Clinical characteristics included knee flexion contracture and increased hamstring tightness. We demonstrate how the prefailure crouch position of the knee increases the flexor moment arm about the knee. We suggest that this knee crouch position during walking is the primary cause of pathology. Failure of the knee extensor mechanism is associated with a distinctive knee kinematic pattern. Regular gait analysis can help identify this pathology and enable treatment to be planned accordingly. (c) 2010 Wiley-Liss, Inc.
