    Many parents stressed the need for greater clarity about the aims of therapy interventions discount imitrex 50mg visa. For example discount 50 mg imitrex with visa, one parent described a situation when their child had identified riding a bicycle as her goal discount 50mg imitrex otc, but instead she was offered a tricycle. Parents who had accessed private provision often identified this as one of the most valued aspects of using private providers. In addition, parents valued feeling well informed about the therapy options available to their child.

As this parent described: My OT [occupational therapist] and physio communicate. Often during these discussions reference was made to a perceived lack of attention and resources available for speech and communication support. Parents consistently valued therapists who took a wider interest in the child and family and who were able and prepared to offer, where appropriate, wider advice. Within this, parents welcomed therapists speaking with colleagues in other therapy teams or services to ensure co-ordinated and consistent approaches to the care and management of the child. Working in partnership with parents Finally, we would note and reiterate material reported earlier in this chapter regarding the way therapists worked with parents, in particular whether or not there was a sense of partnership, respect and shared objectives. There is increasing recognition of the importance of detailed and accurate reporting of the active ingredients of pharmacologic interventions in reports of evaluations and 27–29 intervention manuals. Referred to as complex interventions,31 they may well have one or more of the following features: l involve several interacting components l require many different behaviours from health-care professionals or participants for successful delivery l be aimed at different levels within an organisation l be tailored to different contexts or settings. A recent review comparing reporting of the active ingredients for pharmacologic interventions and non-pharmacologic interventions found it significantly poorer for the latter. The complexity of such interventions, and a lack of understanding or evidence regarding the mechanisms of change, are likely contributors to this. Before moving on to do so, we briefly discuss three overarching issues: levels of complexity, understandings of the active ingredients of therapies and therapist versus therapy. Levels of complexity All interviewees agreed that physiotherapy, occupational therapy and speech and language therapy are complex interventions. It was also argued that because the interventions are being delivered to children, and a diagnosis of neurodisability is present, the level of complexity increases. This was particularly the case when the neurodisabilty resulted in multiple and severe impairments.

I1 We are dogged in therapy by multiple, sometimes not that plausible, hypothesised change mechanisms that are rarely explicitly articulated. The best way to work is multidisciplinary, but to show the contribution of SLT [speech and language therapy] there is very, very difficult. I2 This was the case even for longstanding techniques. The following quotation is on the use of standing frames in physiotherapy:. Is it getting children to stand at the same height as their peers? People also report a benefit in breathing, and bladder and bowel function. And so you may well [need] a series of different outcome measures for each individual child for one intervention.
