Methods Design A descriptive case study design, taking the delivery and practice of therapy interventions as the case, was adopted. Qualitative research methods (interviews and focus groups) were used. Focus groups and individual interviews were used to collect data. Inclusion criteria The scope of the study was set according to the following criteria. The domains captured by this concept include participation in learning and applying knowledge; general tasks and demands; communication; mobility; self-care; domestic life; interpersonal interactions and relationships; major life areas; and community, social and civic life. This criterion includes interventions delivered directly by therapy staff, or by school staff, parents and/or children, in the home or in a school setting, under instruction from therapy staff. This includes children with cerebral palsy (defined as physical, medical and developmental difficulties caused by injury to the immature brain), brain injury, some metabolic and neurogenetic disorders, and developmental co-ordination disorder, as well as those without a specific diagnosis. Within and across these patient groups, the extent to which physical/motor abilities are affected varies considerably. For many of these children and young people, the presence of neurodisability results in a number of physical/motor and cognitive impairments. Data sources The study sought to recruit the following stakeholder groups: 1. More than 70 professionals (therapists, service leads, paediatricians and education staff) and 25 parents took part in the study either through individual interviews or by taking part in a focus group. It did not prove possible to recruit children and young people. The recordings were used to create detailed interview summaries organised under the themes covered in the topic guides. The research team met regularly throughout the data collection period to reflect on a priori and emerging topics and issues. These maps were then modified to create a structure into which analytical writings, summarising findings on each theme, could be organised. Drafts of the findings sections of the project report were shared and reviewed by all members of the research team and final versions were agreed. Results Professionals and parents were clear in their belief about the necessity and importance of therapy interventions with respect to the care, management and support of children with neurodisability. The three professions are in a state of dynamic change and development. This appears to be taking place in response to, or influenced by, three separate issues: l debates and conceptual understandings of disability and impairment l shifts in thinking taking place in other professions and disciplines, and related evidence, regarding goals-focused working, family-centred approaches and supporting self-management l significant resource constraints. In terms of the practice of therapy, the key distinctive features are professional autonomy and highly individualised approaches to delivering therapy. Manualised, or protocol-driven, interventions are unusual. There are early signs of a move to care pathways and the application of protocols within this structure. Much of the direct work of delivering therapy to a child is carried out by parents and school staff. Increasingly, therapists assume a consultative role and their skills in this regard are, therefore, critical. Existing frameworks for understanding complex non-pharmacological interventions offer a useful structure by which this complexity can be understood. Related to this, understandings of mechanisms of change are limited. Parents and professionals strongly identified participation as one of the overarching objectives of therapy interventions. In addition, as a concept or intervention objective, it may not be explicitly operationalised in practice. Furthermore, the notion of participation as an appropriate and meaningful outcome indicator for therapy interventions was questioned, particularly with respect to, for example, evaluations of a specific procedure. There was agreement that, when properly implemented into a study design, it may be an appropriate indicator in studies evaluating the impact of wider models of care.

In the early stages of PD, the duration diffusely distributed throughout the CNS: motor striatum of benefit following a single dose of levodopa is long lasting (D1, D2), hippocampus (D5), frontal cortex and amygdala and far exceeds the plasma half-life of the drug (60 to 90 (D4), hypothalamus (D3, D5), and mesolimbic system minutes) (32).
