The process of developing a non-medical (advanced allied health) botulinum toxin A prescribing and injecting model of care in a public rehabilitation setting.

OBJECTIVE: The aim of this paper was to describe the process undertaken to develop a non-medical (advanced allied health extended role) botulinum toxin A prescription and injection project for adults with upper and lower limb spasticity secondary to an acquired brain injury. The hypertonicity clinic in the present study was located in a metropolitan public hospital in Queensland where multidisciplinary services are provided by a rehabilitation specialist and an advanced occupational therapist and physiotherapist. METHODS: The process of developing the model included establishing potential benefits for the role extension project and documentation of a project plan. RESULTS: Project outcomes included the development of a relevant governance structure, a research evidence-based project evaluation framework, a draft research ethics application, delineation of the key eligibility criteria and competencies required for physiotherapist and occupational therapist prescribers, and a final project report. CONCLUSION: Non-medical prescribing has the potential to increase patient access to botulinum toxin A injection for the management of focal spasticity. A process that supports early patient engagement, extensive consultation with relevant stakeholders, a strong governance structure, a high-quality research project and a long lead time may maximise the potential for successful completion of advanced allied health role extension projects, including prescription and injection of botulinum toxin A.

Individualised resting hand splints for adults with acquired brain injury: a randomized, single blinded, single case design.

AIM: To evaluate the effect of individualized resting mitt splints on hypertonicity (spasticity and tissue stiffness) and passive range of motion (PROM). METHODS: A randomized, single blinded, single case design. Ten adults with acquired brain injury were randomized to control (no-splint) and experimental (splint) groups. The experimental group received an individualized (wrist position, wearing schedule) thermoplastic resting mitt splint. Measures included wrist and finger PROM, muscle stiffness (Modified Ashworth Scale), and spasticity (Modified Tardieu Scale) which were taken at five time points. RESULTS: Between-group analyses indicated a statistically significant effect on PROM at the wrist (d = 2.14, CI95 = 0.57, 3.72, p < 0.05) and clinically important effects on finger PROM, and wrist and finger spasticity and stiffness. Within-group analyses indicated that splint-wear resulted in positive clinical effects ranging from zero effect (maintenance of pre-splinting status) to a large positive treatment effect. Non splint-wear resulted in negative clinical effects ranging from zero effect to a large negative treatment effect. CONCLUSION: Individualized resting splints for adults with moderate hypertonicity and no soft tissue contracture resulted in positive clinical effects to PROM, muscle stiffness and spasticity. Long-term splint-wear may be more beneficial than short-term wear, and may prevent the negative changes evident with no splint-wear. Resting hand splints should be considered for a select group where reduction in muscle stiffness and spasticity, or maintenance of PROM, is desired.

Casting for upper limb hypertonia: a retrospective study to determine the factors associated with intervention decisions.

AIM: To determine if a Clinical Reasoning Protocol assisted occupational therapists to consistently choose casting as an intervention in the context of moderate/severe upper limb hypertonia and possible contracture. METHODS: Sixty-four intervention decisions (including strength/movement training, splinting and/or casting) were drawn retrospectively from initial reports at a community clinic. Associations between identified upper limb characteristics, stated clinical aims and intervention decisions were analysed using logistic regression. RESULTS: Casting was statistically significantly likely to be chosen in the presence of moderate (CI(95) 1.88-39.80, p=0.01) or severe hypertonicity (CI(95) 1.34-135.98, p=0.03), and if the stated clinical aim was to reduce hypertonicity (CI(95) 2.01-18.10, p=0.001) or contracture (CI(95) 1.31-12.73, p=0.02). When reports included both these clinical aims, there was a highly significant association with the decision to cast (CI(95) 5.67-9.13, p=0.001). Where casting was indicated as appropriate, but not chosen as an intervention, mitigating factors included older age (70-95 years), limited personal support and a clinical aim of comfort/hygiene maintenance. CONCLUSION: Occupational therapists using the Protocol consistently chose casting as an upper limb intervention for adults who demonstrated moderate/severe hypertonicity, contracture or limited functional ability. Prospective research is required to determine intervention outcomes following use of the Protocol.

Do clients with acquired brain injury use the splints prescribed by occupational therapists? A descriptive study.

Clients with acquired brain injury often demonstrate hypertonicity and decreased function in their upper limbs, requiring appropriate intervention. Splinting is one of the intervention methods that is widely used to address these issues. Literature shows that some clients are not using splints following fabrication. However, there is a paucity of research about the factors that influence clients to use or not use splints. This study aims to investigate these influential factors for clients with upper limb hypertonicity. Two survey tools including therapist and client questionnaires were developed and completed by both therapists and clients. Six therapists and 14 clients participated in this study and completed the relevant questionnaires. The results illustrate that most clients (13 out of 14) were continuing to use their splints four weeks following discharge from hospital. The main goals of choosing splints for both therapists and clients were prevention of contracture and deformity. The most indicated client reasons for adhering to the splint wearing program were therapist-related factors including clients' trust and reliance on their therapists. Further reasons for clients implementing the recommended splint-wearing program and clinical implications are discussed.

Clinical reasoning in neurology: use of the repertory grid technique to investigate the reasoning of an experienced occupational therapist.

BACKGROUND/AIM: The aim of this paper is to describe the use of a structured interview methodology, the repertory grid technique, for investigating the clinical reasoning of an experienced occupational therapist in the domain of upper limb hypertonia as a result of brain injury. METHOD: Repertory grid interviews were completed before and after exposure to a protocol designed to guide clinical reasoning and decision-making in relation to upper limb neurological rehabilitation. Data were subjected to both qualitative and quantitative analyses. RESULTS: Qualitative analysis focussed on clinical reasoning content. Common themes across the pre- and post-exposure interviews were the use of theoretical frameworks and practice models, the significance of clinical expertise, and discrimination of 'broad' and 'specific' aspects, as well as differentiation between 'therapist and client-related' aspects of the clinical situation. Quantitative analysis indicated that for both pre- and post-exposure repertory grids, clinical reasoning was structured in terms of two main concepts. In the pre-exposure grid, these were related to the therapist's role, and to the 'scope' of practice tasks (either broad or specific). In the post-exposure grid the two main concepts were upper limb performance, and client-centred aspects of the therapy process. CONCLUSIONS: The repertory grid technique is proposed as an effective tool for exploring occupational therapy clinical reasoning, based on its capacity for accessing personal frames of reference, and elucidating both the meaning and the structure supporting clinical reasoning.

The structure of novice and expert occupational therapists' clinical reasoning before and after exposure to a domain-specific protocol.

BACKGROUND/AIM: The research aimed to determine the influence of a protocol designed for use in the domain of upper limb hypertonia due to brain injury on novice and expert occupational therapy clinical reasoning. METHOD: Individual, structured repertory grid interviews were completed with 13 novice and eight expert occupational therapists prior to, and following, exposure to a domain-specific clinical reasoning protocol. Data were subjected to quantitative analyses (Principal Components Analysis, Generalised Procrustes Analysis). RESULTS: Novice participants demonstrated statistically significant change in the structure of their clinical reasoning following exposure to the protocol (P < 0.004). Prior to exposure, novices relied on therapy tasks, the problem-solving process, environmental factors and standard practice to structure their reasoning. Following exposure, novices' clinical reasoning changed to more closely reflect experts' reasoning. Thus, a 'structured approach' and (theoretical) practice perspectives became evident. Prior to exposure to the protocol, experts structured reasoning in terms of (personal and theoretical) practice perspectives, therapy tasks and the scope of such tasks (either 'general' or 'specific'). Following exposure, therapist/client collaboration and upper-limb-related constructs emerged as being used to structure experts' reasoning, although these changes were not statistically significant. CONCLUSION: A protocol designed for guiding clinical reasoning in the context of upper limb hypertonia was perceived to be conceptually useful by novice and expert occupational therapists.
