This paper presents the design and validation of a lower limb exoskeleton robot for post-stroke patients at the early stage of neurorehabilitation. Instead of the usual walking gait, the popular exercise, recumbent cycling, is adopted to provide a safe and comfortable movement training to the patients who lost active motor abilities due to a very low muscle power. The exoskeleton robot mounted on a commercial wheelchair possesses two pairs of hip and knee joints on the right and left legs, respectively, and each joint has one degree of freedom actuated by a custom-made linear actuator in the sagittal plane. Additionally, two passive ankle joints are added to provide a limited range of motion for human comfort. The hip and knee joint motion profiles were calculated based on a simplified kinematic model of the recumbent cycling modality, and implemented through the motor position–velocity–time trajectory. Clinical trials were conducted on six stable post-stroke patients with a low muscle power under the supervision of a skilled therapist. The preliminary results validated the functionality and feasibility of the new exoskeleton robot and showed a promising application of the recumbent cycling modality in robot-assisted neurorehabilitation.

Background/Aims 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. Methods 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. Results 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. Conclusions 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.

The purpose of this systematic review and meta-analysis is to evaluate the long-term efficacy of Extracorporeal Shock Wave Therapy (ESWT) on reducing lower limb post-stroke spasticity in adults. A systematic electronic search of PubMed/ MEDLINE, Physiotherapy Evidence Database (PEDro), Scopus, Ovid MEDLINE(R), and search engine of Google Scholar was performed. Publications that ranged from January 2010 to August 2020, published in English, French, Spanish, Portuguese, and Italian language and available as full texts were eligible for inclusion and they were searched without any restrictions of country. The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and followed the recommendations of the Cochrane Handbook for Systematic Reviews of Interventions. Two authors screened the references, extracted data, and assessed the risk of bias. The primary outcome was spasticity grade mainly assessed by the Modified Ashworth Scale (MAS). Secondary outcomes were passive range of motion (PROM), pain intensity, electrophysiological parameters, gait assessment, and adverse events. A total of seven recent randomized controlled trials (RCTs) were included in the systematic review and meta-analysis, and a beneficial effect on spasticity was found. The high level of evidence presented in this paper showed that ESWT ameliorates spasticity considering the parameters: MAS: standardized mean difference (SMD) = 0.53; 95% confidence interval (95% CI): (0.07–0.99); Modified Tardieu Scale (MTS): SMD = 0.56; 95% CI: (0.01–1.12); Visual Analogue Scale (VAS): SMD = 0.35; 95% CI: (−0.21–0.91); PROM: SMD = 0.69; 95% CI: (0.20–1.19). ESWT presented long-term efficacy on lower limb post-stroke spasticity, reduced pain intensity, and increased range of motion. The effect of this novel and non-invasive therapy was significant and the intervention did not present adverse events, proving a satisfactory safety profile.
