RESUMO

This study explores the efficacy of our novel and personalized brain-computer interface (BCI) therapy, in enhancing hand movement recovery among stroke survivors. Stroke often results in impaired motor function, posing significant challenges in daily activities and leading to considerable societal and economic burdens. Traditional physical and occupational therapies have shown limitations in facilitating satisfactory recovery for many patients. In response, our study investigates the potential of motor imagery-based BCIs (MI-BCIs) as an alternative intervention. In this study, MI-BCIs translate imagined hand movements into actions using a combination of scalp-recorded electrical brain activity and signal processing algorithms. Our prior research on MI-BCIs, which emphasizes the benefits of proprioceptive feedback over traditional visual feedback and the importance of customizing the delay between brain activation and passive hand movement, led to the development of RehabSwift therapy. In this study, we recruited 12 chronic-stage stroke survivors to assess the effectiveness of our solution. The primary outcome measure was the Fugl-Meyer upper extremity (FMA-UE) assessment, complemented by secondary measures including the action research arm test, reaction time, unilateral neglect, spasticity, grip and pinch strength, goal attainment scale, and FMA-UE sensation. Our findings indicate a remarkable improvement in hand movement and a clinically significant reduction in poststroke arm and hand impairment following 18 sessions of neurofeedback training. The effects persisted for at least 4 weeks posttreatment. These results underscore the potential of MI-BCIs, particularly our solution, as a prospective tool in stroke rehabilitation, offering a personalized and adaptable approach to neurofeedback training.

RESUMO

BACKGROUND: Cancer-related fatigue (CRF) is a common debilitating condition. International evidence supports an exercise prescription for CRF. The majority of Australians with cancer do not meet recommended exercise targets. AIMS: To analyse the effects of a guideline-based supervised exercise programme on CRF among a representative private hospital cancer patient sample (n = 268). METHODS: We collected data from 268 patients recruited from haematology and oncology over a 5-year period. Participants underwent a 3-month CRF exercise programme based on internationally recognised exercise guidelines. The programme, conducted by a multidisciplinary team, operated twice weekly sessions of 2 h duration comprising aerobic, resistance and balance exercises; hydrotherapy and condition counselling; fatigue management; and dietetic, speech pathology and swallowing education (head and neck cancers). The effect of the programme was measured in relation to the following outcomes: Functional Assessment of Chronic Illness Therapy, Fatigue (self-reported fatigue); Functional Assessment of Cancer Therapy, general quality of life (health-related quality of life in cancer); six-minute walk test; and Lawton's Instrumental Activities of Daily Living Scale. RESULTS: Multivariate outcomes showed statistically significant improvements in all four major outcome measures, plus a programme effect of greater than 0.7 for each outcome variable. The programme treatment outcomes were consistent over the 5 years of the programme. CONCLUSIONS: The outcomes of this programme contribute to exercise guidelines in Australia. Currently only position statements exist on the subject, but there are no programme guidelines. An exercise prescription is critical to cancer outcomes. This programme is likely to benefit cancer survivors experiencing CRF across private and public hospitals in Australia.

RESUMO

BACKGROUND: Individuals with significant post-stroke impairments often move to residential care. The prevalence of spasticity is high among these residents. Palmar ulceration is an under-recognised complication of unmitigated post-stroke hand spasticity. The ulcerations are painful, emit offensive smell and cause significant suffering for the individuals and the carers. OBJECTIVE: The aim of this article is to discuss the healing of these ulcerations by reducing spasticity in the hand muscles with botulinum toxin A (BoNTA) injection followed by dressing, splinting and hand therapy. DISCUSSION: This article discusses the epidemiology, anatomy and clinical presentations of spastic hand ulcerations and mechanisms of action of BoNTA in alleviating the ulcers and related symptoms such as pain, sweating, offensive smell, and lessening the carer burden. The primary neuromuscular blocking action of BoNTA results in the opening of the hand, allowing dressing and ease of care. The toxin provides pain relief, inhibits excessive sweat production and causes vasodilatation, ultimately resulting in healing of the ulcerations.

RESUMO

We performed a systematic review and meta-analysis of randomised controlled trials (RCTs) conducted from January 2005 to June 2021 to update the evidence of Botulinum toxin A (BoNT-A) in neuropathic pain (NP) in addition to quality of life (QOL), mental health, and sleep outcomes. We conducted a Cochrane Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria analysis of RCTs from the following data sources: EMBASE, CINAHL, WHO International Clinical Trial Registry Platform, ClinicalTrials.gov, Cochrane database, Cochrane Clinical Trial Register, Australia New Zealand Clinical Trials Registry, and EU Clinical Trials Register. Meta-analysis of 17 studies showed a mean final VAS reduction in pain in the intervention group of 2.59 units (95% confidence interval: 1.79, 3.38) greater than the mean for the placebo group. The overall mean difference for sleep, Hospital Anxiety and Depression Scale (HADS) anxiety, HADS depression, and QOL mental and physical sub-scales were, respectively, 1.10 (95% CI: -1.71, 3.90), 1.41 (95% CI: -0.61, 3.43), -0.16 (95% CI: -1.95, 1.63), 0.85 (95% CI: -1.85, 3.56), and -0.71 (95% CI: -3.39, 1.97), indicating no significance. BoNT-A is effective for NP; however, small-scale RCTs to date have been limited in evidence. The reasons for this are discussed, and methods for future RCTs are developed to establish BoNT-A as the first-line agent.

RESUMO

BACKGROUND: Post-stroke lower limb spasticity (PSLLS) has a prevalence of 28-37%. PSLLS can cause difficulty in walking and reduce quality of life (QOL). Post stroke spasticity impairs the ability to intervene to improve walking ability. Botulinum Toxin A (BT) is an effective intervention for focal spasticity, but its use is currently restricted in many countries by their reimbursement system stating that the evidence for improvement in walking and quality of life (QOL) is not robust for treatment in the lower limb. This randomized control trial (RCT) will investigate the effectiveness of BT in modifying spasticity, and improving functioning (mobility, walking, activities of daily living (ADL's) and QOL. METHODS/DESIGN: A double-blind placebo-controlled trial injection will assess the effect of BT compared with a placebo (normal saline) in a sample of n = 94 patients. Following treatment of spasticity measured by Modified Ashworth Scale (MAS), the primary outcome of gait velocity will be measured by i) Gait Rite (Electronic Walkway); ii) walking by 2 Min Walk Test; iii) balance by Berg Balance Scale; mobility by iv) Timed Up and Go (TUG); v) lower limb function by ABILICO; vi) patient related goal by Goal Attainment Scale (GAS); vii) QOL by SF 12 (Rand version); viii) activities of daily living by the Functional Autonomy Measurement System (SMAF). There will be an associated health economic analysis. DISCUSSION: The study methodology is based on our systematic review 2026 studies, which concluded the evidence for improving mobility following use of BT to reduce spasticity was not robust. The results of this study could establish the use of BT in improving gait and lower limb function in PSLLS. This study could provide the evidence needed for reimbursement schemes to consider and changes to its funding policy for BT in PSLLS. TRIAL REGISTRATION: The trial is registered with the Australia New Zealand Clinical Trails Registry (ANZCTR)- ANZCTRN12617001603303 . Registered 07/12/2017.

RESUMO

Foot dystonia (FD) is a disabling condition causing pain, spasm and difficulty in walking. We treated fourteen (14) adult patients experiencing FD with onabotulinum toxin A injection into the dystonic foot muscles. We analyzed the spatiotemporal gait utilizing the GaitRite system pre- and 3 weeks post-botulinum toxin injection along with measuring dystonia by the Fahn⁻Marsden Dystonia Scale (FMDS), pain by the Visual Analog Scale (VAS) and other lower limb functional outcomes such as gait velocity, the Berg Balance Scale (BBS), the Unified Parkinson's Disease Rating Scale⁻Lower Limb Score (UPDRS⁻LL), the Timed Up and Go (TUG) test and the Goal Attainment Scale (GAS). We found that stride length increased significantly in both the affected (p = 0.02) and unaffected leg (p = 0.01) after treatment, and the improvement in stride length was roughly the same in each leg. Similar results were found for step length (p = 0.02) with improvement in the step length differential (p = 0.01). The improvements in the lower limb functional outcomes were also significant-FMDS, VAS, TUG, and UPDRS⁻LL decreased significantly after treatment (all p < 0.001), and BBS (p = 0.001), GAS (p < 0.001) except cadence (p = 0.37). BT injection improved walking in foot dystonia as evidenced through gait analysis, pain and lower limb functional outcomes. Main study limitations were small sample size and lack of control.
