Traditional schools of thought Different schools of thought advocate cheap mycelex-g 100mg otc jessica antifungal nail treatment, or stipulate discount mycelex-g 100mg with mastercard antifungal tablets over the counter, different techniques or procedures to use with a child. Alternatively, they may posit different views on the mechanisms of change underlying technique or procedure. This notion of distinct schools of thought appears to be very similar to that observed in other specialisms. Bobath and sensory integration theory also emerged as divisive schools of thought in our interviews with occupational therapists. As is a common theme through many of our data, there was a sense that these distinct, traditional schools of thought were, and would continue to become, less dominant. One of the key drivers for this appears to be the ongoing, higher-level reconstructions of what therapy is and what its objectives should be, which we described in the previous section. Emerging schools of thought The shifts in overall approach described earlier – from a deficit model to activity-based and now goals-focused/participation ways of working – appear, however, to have led to the emergence of new schools of thought within the professions. Of those described to us during the study, these typically drawing on principles or approaches developed within other specialisms. Early intervention The final school of thought, applicable across all therapies, was the notion that early intervention is essential, and this should be the time when the intensity of the intervention is at its greatest. The rationale for early intervention is that it is likely to yield greater impact: supporting development and preventing permanent damage and/or deterioration. This argument is based on notions of neuroplasticity, physical and cognitive development. Thus, it was also typically reported that the intensity of therapy interventions decreases as the child grows older (or in terms of time since brain injury). However, what was less clear was the rationale for tailing off therapy; indeed, it was a source of concern among some interviewees. Therapy is front-loaded so families get most at the preschool stage, some in primary school, rarely any in secondary school and none as adults.

THERAPY INTERVENTIONS: APPROACHES AND TECHNIQUES Techniques, procedures and equipment used by the different therapies The purpose of this scoping study was not to provide an account of the enormous range of techniques, procedures and equipment currently being used by therapists in England. A different methodology would be required to generate such data. We describe this in terms of a number of concepts: l professional autonomy l responsive practice l managing prognostic uncertainty l the role of protocols and care pathways l working out of a tool box l mode of delivery. Professional autonomy A first overarching principle of practice within therapies is the concept of professional autonomy. In many interviews, therapists were presented as working in an autonomous, individualistic way within their scope of practice (or qualification): Assessment and hands-on work is probably more individualised, but we all sign up from the same baseline. M2 This autonomy operated both in the choice of interventions and in the intensity, or dose, of the interventions. Despite this notion of autonomy, some interviewees noted that, within the NHS, practice has become more standardised over the past decade, driven by emerging evidence and the shift in overall approach to providing these therapies. The publication of protocols and the implementation of care pathways – both described below – also contributed to a standardisation of practice. Responsive practice The ability to make an ongoing assessment, even within the context of specific session, of the way a child is responding to an intervention and/or their ability or motivation to engage with an activity or procedure (sometimes on a moment-by-moment basis) was regarded as a core therapy skill. Over time, I may adapt and change the goals in order to make progress. So it may be we set off on an eclectic approach, [thinking]. First, it was used to refer to the way in which a team or service managed a referral to their service. Thus, some study participants described the development, and early implementation, of a number of care pathways within their service, each specific to a particular presenting need or diagnosis.
