Mobilisation And Tactile (Sensory) Stimulation For The Foot Post Stroke: Opinions And Perceptions Of Experienced Therapists

Intensive proprioceptive stimulation applied to the paretic hand post-stroke, using a complex hands-on intervention known as mobilisation and tactile stimulation, has reduced motor impairment and improved hand function in sub-acute and chronic stroke. While, anecdotally, mobilisation and tactile stimulation is also applied to the paretic foot to prepare it for standing, its use in stroke rehabilitation and effects on standing and balance have not been evaluated. Therefore, expert clinicians' experiences, opinions and perceptions of using mobilisation and tactile stimulation in routine clinical practice were explored to inform a subsequent feasibility study of mobilisation and tactile stimulation for the paretic foot post-stroke. Following ethical approval, focus groups were undertaken: using purposive sampling, physiotherapists and occupational therapists with >12 months experience of stroke rehabilitation were recruited from a regional special interest group. A pilot study (n=4) and main study (n=7) explored content and application of hands-on therapy for the paretic foot, and the perceived impact of sensory loss on lower limb function. Data were audio-taped and transcribed verbatim. Thematic analysis was undertaken. All 11 therapists had previous experience of using mobilisation and tactile stimulation for the foot post-stroke. Three main themes were identified: (1) therapeutic intervention (sub-themes: therapy content, sensation, adjuncts, the foot as an active base of support and preparation for function); (2) 24-hour care; and (3) analysis (sub-themes: outcome measures, response to treatment). The most common adjuncts to mobilisation and tactile stimulation were orthotics and task-specific training. The importance of mobilisation and tactile stimulation in restoring foot alignment, sensory feedback and progression of the patient towards weight bearing and ambulation in the clinical setting was highlighted. Mobilisation and tactile stimulation is a complex intervention used in stroke rehabilitation to enhance weight bearing and ambulation post stroke. Further research into its effects on the foot and lower limb is warranted in order to evaluate it and determine its evidence base for inclusion in routine clinical practice. Alternative methods of applying proprioceptive stimulation should also be considered, for example use of textured insoles, and relative effectiveness of these explored in clinical trials.
