Description of intervention(s) / exposure
Two participant groups are provided with interventions:

1. Clinicians (occupational therapists and physiotherapists)
2. Stroke survivors presenting with sensory loss

Participant Group 1 (Clinicians):

Theory-based implementation strategies (i.e, group educational workshops and interactive online resources) will be provided to occupational therapists and physiotherapists working with stroke survivors from participating health organisations.

Examples of theory-based implementation strategies to be used are:
1. Barrier identification and evaluation through implementation questionnaires
2. Group-based educational workshops providing training in evidence-based assessment and treatment methods for post-stroke somatosensory loss (the SENSe approach, Carey et al., 2011)
3. Establishment of site-specific champion-therapists through liaison between participating sites and the research team
4. Provision of written materials and online resources relevant to post-stroke sensory assessment and treatment.

Theoretical approaches to guide implementation interventions will be based primarily on the Theoretical Domains Framework and the Behaviour Change Wheel (Cane et al., 2012; Michie et al., 2005; Michie, van Stralen & West, 2011).

Cane, J., O’Connor, D., & Michie, S. (2012). Validation of the theoretical domains framework for use in behaviour change and implementation research. Implement Science, 7(1), 37.

Therapists will be up-skilled in assessment (training sessions of ~ 5 hours, over 3 sessions across 3 weeks ) and treatment (training sessions of ~8 hours, over 3 sessions across 3 weeks) approaches using interactive workshops facilitated by trained clinical researchers and involving multimedia resources.

Participant Group 2 (Stroke survivors):

Stroke survivors will be provided with SENSe therapy or usual care. SENSe is an upper limb therapy package for use with stroke survivors (Carey et al., 2011) comprising modules to train:

* Tactile discrimination
* Limb position sense
* Tactile object recognition
* Occupational performance in tasks selected as meaningful by the client

Carey, L.M, Macdonell, R., & Matyas, T. A. (2011). SENSe: Study of the Effectiveness of Neurorehabilitation on Sensation A Randomized Controlled Trial. Neurorehabilitation and neural repair, 25(4), 304-313.

Stroke survivors will receive 10 therapy sessions of 60 minute duration with sessions aimed at a rate of 3 per week, with variations depending on the nature of service delivery of participating sites. SENSe therapy sessions are one-on-one between therapist and patient.

Usual care, as comparison to SENSe therapy, will constitute the therapy currently being provided to treat stroke survivors with sensory loss and the frequency of sessions and timeframes for delivery will be dependent on usual practices of participating sites. Details of therapy provided as part of usual care will be monitored via a questionnaire and results will be interpreted with reference to ‘usual care’ as defined by a recent cross-sectional study of 172 therapists across Australia (Pumpa et al., 2015).

Pumpa, L., Cahill, L., & Carey, L.M. (2015). Somatosensory assessment and treatment after stroke: An evidence practice gap. Australian Occupational Therapy Journal. 62(2).

Phases of this study include:

Phase 1: Therapists implement evidence-based quantitative assessment of sensation using the SENSeAssess tool. Treatment approaches to address sensory loss remain unchanged (usual care).
Phase 1 will commence after 3 weeks of SENSe Assess training has been completed.

Phase 2: Therapists implement an evidence-based treatment approach (SENSe Therapy) with stroke clients.
Stroke survivors will receive 10 therapy sessions of 60 minute duration. SENSe therapy sessions are one-on-one between therapist and patient.

Phase 2 will commence after 3 weeks of SENSe therapy training has been completed.

Comparator / control treatment
Usual Care. During Phase 1 of the study, occupational therapists and physiotherapists will provide usual care (in relation to sensory rehabilitation) to stroke survivors. Usual care is the therapy normally provided to stroke survivors and is likely to have natural variations depending on the local context. In the context of this study, usual care will be interpreted with reference to ‘usual care’ as reported in a cross-sectional study of current practices in somatosensory assessment and treatment (Pumpa, 2015). For example, the results of this Australian review of practice indicated therapists predominantly use compensatory strategies and sensory re-education in the treatment of stroke survivors with somatosensory loss.

Outcomes
Primary outcome [1] 293661 0
Participate Group 1 (Clinicians):
Effective implementation will be evaluated via clinician questionnaires specifically designed for this study and focus groups. An audit of medical histories will also be used.
Timepoint [1] 293661 0
Participant Group 1 (Clinicians):
Questionnaires and focus groups will be conducted at baseline prior to phase one (usual care), following recruitment of half of the site-specific nominated sample (~6-8 month timeframe) and after the period of implementation of SENSe therapy (~6-8 month timeframe). Audit of histories will occur following phase 1 and phase 2.
Primary outcome [2] 295290 0
Participant Group 2 (Stroke Survivors): Improved upper limb somatosensory function in stroke survivors will be measured by the SENSeAssess© tool (Carey et al. 2013). SENSeAssess© is a composite measure of functional somatosensory discrimination capacity derived from standardised measures of texture discrimination, limb position sense and tactile object recognition. Tests contributing to the composite measure of sensation will address texture discrimination (Tactile Discrimination Test, Carey, Oke & Matyas, 1997), limb position sense (Wrist Position Sense Test, Carey, Oke & Matyas, 1996) and tactile object recognition (Functional Tactile Object Recognition Test, Carey et al., 2006). Each component measure has age-adjusted normative standards, high reliability (r = 0.85 to 0.92) and good discriminative test properties. Carey L, Mak Y, Tan A-M, Rickard, K and Matyas T.

Efficacy
Statistical methods / analysis
A power calculation was used to determine the number of participants needed to achieve study objectives. Based on an effect size of d=0.79 from the randomised controlled trial of SENSe Therapy (Carey et al., 2011) and 80% power, taking into account the potential impact of variation in therapist experience and adaptation to local context, our sample size is based on 80% power for detecting an effect that is 0.6 of the SENSe d, i.e. n=140.

Methods of data analysis:

Participant Group 1 (Clinicians):
Quantitative information from clinician questionnaires and qualitative components of focus group discussion will be collected. Descriptive statistics and thematic analysis will be used to interpret results.

Participant Group 2 (Stroke Survivors):
Planned comparisons of pre-post intervention data will contrast:

i) the reduction in standardised sensory deficit score during 'usual care' and SENSe rehabilitation phases (the group effect of SENSe intervention across sites and patients).

ii) reduction in standardised sensory deficit score during 'usual' compared to SENSe intervention at each site, taking into account possible clinic effect.

Comparison will occur statistically through a two factor ANOVA with centre (health organization sites) and Intervention (usual care, SENSe therapy) being the two factors.

Confidence intervals will be determined for the mean differences between the intervention and 'usual care' groups to estimate typical effect magnitudes.

An independent statistician will perform a blinded analysis of pre- and post- test data.
