Robot-assisted task-specific training in cerebral palsy.

Our goal was to examine the feasibility of applying therapeutic robotics to children and adults with severe to moderate impairment due to cerebral palsy (CP). Pilot results demonstrated significant gains for both groups. These results suggest that robot-mediated therapy may be an effective tool to ameliorate the debilitating effects of CP and provide new opportunities for reducing impairment and improving coordination.

Ventilator weaning outcomes in chronic respiratory failure in children.

The purpose of this study was to describe mechanical ventilation weaning outcomes for children with chronic respiratory failure discharged from one of six post-acute rehabilitation facilities. Demographic, clinical and outcome data were collected from the medical record. Forty-four children were included in this prospective series; 20 (45%) were weaned off the ventilator at discharge. Children required significantly lower levels of ventilatory support at discharge than admission. Hourly use on the ventilator decreased from admission to discharge for the full cohort and for the subgroup who required a ventilator at discharge. Seventy-five percent of the children discharged with a ventilator had a portable unit. We conclude that nearly half of the children using mechanical ventilation achieve weaning during a postacute rehabilitation admission, whereas others have positive outcomes in severity, hours off the ventilator or portability of equipment.

Pediatric post-acute care hospital transitions: an evaluation of current practice.

OBJECTIVES: After discharge from an acute care hospital, some children require ongoing care at a post-acute care hospital. Care transitions occur at both admission to the post-acute care hospital and again at discharge to the home/community. Our objective was to report the current practices used during the admission to and discharge from 7 pediatric post-acute care hospitals in the United States. METHODS: Participants from 7 pediatric post-acute care hospitals completed a survey and rated the frequency of use of 20 practices to prepare and support children and their families during both admission to the hospital and at time of discharge to the home/community. For consistency with existing literature, practices were grouped into 4 previously reported categories: assessment, communication, education, and logistics. Descriptive statistics were used to report the frequency of use within practices and between hospitals. RESULTS: Only 2 of 10 admission practices and 3 of 10 discharge practices were reportedly "always" used by all hospitals. Assessment and communication practices were reported to be more frequently used (57%-100% of the time) than education and logistic procedures. Between hospitals, only the reported frequency of use of the discharge practices was statistically significantly different (P = .03). CONCLUSIONS: Variability exists in transition practices among 7 post-acute care pediatric hospitals. This report is the first known to detail the frequency of use of admission and discharge practices for pediatric post-acute care hospitals in the United States.

The effect of random or sequential presentation of targets during robot-assisted therapy on children.

BACKGROUND: Robot assisted upper extremity therapy has been shown to be effective in adult stroke patients and in children with cerebral palsy (CP) and other acquired brain injuries (ABI). The patient's active involvement is a factor in its efficacy. However, this demands focused attention during training sessions, which can be a challenge for children. OBJECTIVE: To compare results of training requiring two different levels of focused attention. Differences in short term performance and retention of gains as a function of training protocol as measured by the Fugl-Meyer (FM) were predicted. METHODS: Thirty-one children with CP or ABI were randomly divided into two groups. All received 16 one hour sessions of robot-assisted therapy (twice a week for 8 weeks) where they moved a robot handle to direct a cursor on the screen toward designated targets. One group had targets presented sequentially in clockwise fashion, the other presented in random order. Thus, one group could anticipate the position of each target, the other could not. RESULTS: Both groups showed significant functional improvement after therapy, but no significant difference between groups was observed. CONCLUSIONS: Assist-as-needed robotic training is effective in children with CP or ABI with small non-significant differences attributed to attentional demand.

New horizons for robot-assisted therapy in pediatrics.

The field of rehabilitation robotics has grown substantially during the past 15 yrs. Studies of upper limb robot-assisted therapy for adults with moderate to severe hemiparesis after stroke have shown significant gains compared with usual care in isolated control, coordination, and strength in the paretic arm (J Rehabil Res Dev 2006;43:171-84; Top Stroke Rehabil 2007;14:22-44; Neurorehabil Neural Repair 2008;22:111-21). While attempts to increase the understanding of the key active ingredients of these interventions continue, researchers have recently extended their focus to children with neurologically based movement disorders arising from cerebral palsy and acquired brain injury or stroke. This study's aim was to provide a narrative review that highlights recent pediatric studies of robot-assisted therapies for the upper and lower limbs. Potential benefits will be discussed, as well as challenges and needs for future development.

Cerebral palsy: clinical care and neurological rehabilitation.

Cerebral palsy (CP) is defined as motor impairment that limits activity, and is attributed to non-progressive disturbances during brain development in fetuses or infants. The motor disorders of CP are frequently accompanied by impaired cognition, communication, and sensory perception, behavioural abnormalities, seizure disorders, or a combination of these features. CP is thought to affect three to four individuals per 1000 of the general population. The incidence, prevalence, and most common causes of CP have varied over time because of changes in prenatal and paediatric care. Medical management of children and adults involves care from primary-care physicians with input from specialists in neurology, orthopaedics, and rehabilitation medicine. Physicians should also work in conjunction with rehabilitation therapists, educators, nurses, social care providers, and schoolteachers. The focus of rehabilitation treatment has recently shifted to neurological rehabilitation in response to increasing evidence for neuroplasticity. This approach aims to improve development and function by capitalising on the innate capacity of the brain to change and adapt throughout the patient's life. As the life expectancy of individuals with CP approaches that of the general population, therapies must be developed that address the needs of adults ageing with disability.

Outcomes of post-acute hospital episodes for young children requiring airway support.

In this descriptive study, we examined changes in invasive and non-invasive airway support; studied the rates of home discharge vs. long-term care or acute hospitalization; and examined the relationship between the level of airway support and discharge to home for 92 children (<3 years of age) with 104 admission-discharge episodes to a consortium of pediatric rehabilitation hospitals over a one-year period. We found a significant reduction (p < 0.001) in the level of airway support between admission and discharge. In 21 of 47 (45%) episodes, children weaned from mechanical ventilation to a less restrictive type of support. Sixty percent of the children had final discharges to home. There was a significant, though fair correlation (Spearman Rho = -0.344, p = 0.001) between home discharge and level of airway support. These outcomes data provide a multi-site baseline for understanding expected changes in airway support and home discharge rates of young children who are admitted to a post-acute inpatient program.
