This article aims to provide a concise overview of the best available evidence for managing post-stroke spasticity. A modified scoping review, conducted following the PRISMA guidelines and the PRISMA Extension for Scoping Reviews (PRISMA-ScR), involved an intensive search on Medline and PubMed from 1 January 2000 to 31 August 2023. The focus was placed on high-quality (GRADE A) medical, rehabilitation, and surgical interventions. In total, 32 treatments for post-stroke spasticity were identified. Two independent reviewers rigorously assessed studies, extracting data, and evaluating bias using GRADE criteria. Only interventions with GRADE A evidence were considered. The data included the study type, number of trials, participant characteristics, interventions, parameters, controls, outcomes, and limitations. The results revealed eleven treatments supported by GRADE A evidence, comprising 14 studies. Thirteen were systematic reviews and meta-analyses, and one was randomized control trial. The GRADE A treatments included stretching exercises, static stretching with positional orthosis, transcutaneous electrical nerve stimulation, extracorporeal shock wave therapy, peripheral magnetic stimulation, non-invasive brain stimulation, botulinum toxin A injection, dry needling, intrathecal baclofen, whole body vibration, and localized muscle vibration. In conclusion, this modified scoping review highlights the multimodal treatments supported by GRADE A evidence as being effective for improving functional recovery and quality of life in post-stroke spasticity. Further research and exploration of new therapeutic options are encouraged.

Spastic paresis is a common feature of an upper motor neuron impairment caused by stroke, brain injury, multiple sclerosis and other central nervous system (CNS) disorders. Existing national and international guidelines for the treatment of adult spastic paresis tend to focus on the treatment of muscle overactivity rather than the comprehensive approach to care, which may require life-long management. Person-centered care is increasingly adopted by healthcare systems in a shift of focus from "disease-oriented" towards "person-centered" medicine. The challenge is to apply this principle to the complex management of spastic paresis and to include an educative process that engages care providers and patients and encourages them to participate actively in the long-term management of their own disease. To address this issue, a group of 13 international clinicians and researchers used a pragmatic top-down methodology to evaluate the evidence and to formulate and grade the strength of recommendations for applying the principles of person-centered care to the management of spastic paresis. There is a distinct lack of clinical trial evidence regarding the application of person-centered medicine to the rehabilitation setting. However, the current evidence base supports the need to ensure that treatment interventions for spastic paresis should be centered on as far as reasonable on the patient's own priorities for treatment. Goal setting, negotiation and formal recording of agreed SMART goals should be an integral part of all spasticity management programs, and goal attainment scaling should be recorded alongside other standardized measures in the evaluation of outcome. When planning interventions for spastic paresis, the team should consider the patient and their family's capacity for self-rehabilitation, as well as ways to enhance this approach. Finally, the proposed intervention and treatment goals should consider the impact of any neuropsychological, cognitive and behavioral deficits on rehabilitation. These recommendations support a person-centric focus in the management of spastic paresis.

Background: Knee Osteoarthritis (knee OA) is the most common joint disease in the elderly. It is a major cause of walking disability and balance impairment. The balance impairment or increase postural sway may result in increased risk of fall. Objectives: Compare effects of aquatic exercise and land-based exercise on postural sway and physical performance (pain, quality of life, leg muscle strength and leg muscle flexibility) in the elderly with knee OA. Subjects and methods: Fifty elderly women with knee OA were recruited for this study. They were randomized into aquatic exercise (n=25) and land-based exercise group (n=25). Postural sway views by anterior-posterior amplitude, medio-lateral amplitude, and total area were measured in subjects with eye opened or closed during double and single leg stance after six-week training, using the Force platform. Functional outcome was tested by the modified WOMAC. Knee injury and Osteoarthritis Outcome Score (KOOS), and pain scale were tested by Visual Analog Scale (VAS). Leg muscle strength was measured by chair stand, and leg muscle flexibility was measured by sit-andreach test. Aquatic group exercised at King Chulalongkorn Memorial Hospital therapeutic pool, while landbased group exercised at home. Results: In comparing postural sway before and after exercise, reduction in postural sway and pain, and increase in strength, the aquatic group were significantly better than those for land-based group (p 0.05). Conclusion: Elderly patients with knee OA need exercise to improve balance and reduce sway. Six-week aquatic exercise was better than land-based exercise in sway reduction.

Ultrasound (US)-guided botulinum neurotoxin (BoNT) injections are becoming a mainstay in the treatment of muscle spasticity in upper motor neuron syndromes. As a result, there has been a commensurate increase in US-guided BoNT injection for spasticity training courses. However, many of these courses do not emphasize the importance of ergonomics. This paper aims to highlight the importance of ultrasound ergonomics and presents ergonomic recommendations to optimize US-guided BoNT injection techniques in spasticity management. Expert consensus opinion of 11 physicians (4 different continents; representing 8 countries, with an average of 12.6 years of practice using US guidance for BoNT chemodenervation (range 3 to 22 years)). A search using PubMed, College of Physicians and Surgeons of British Columbia database, EMbase was conducted and found no publications relating the importance of ergonomics in US-guided chemodenervation. Therefore, recommendations and consensus discussions were generated from the distribution of a 20-question survey to a panel of 11 ultrasound experts. All 11 surveyed physicians considered ergonomics to be important in reducing physician injury. There was complete agreement that physician positioning was important; 91% agreement that patient positioning was important; and 82% that ultrasound machine positioning was important. Factors that did not reach our 80% threshold for consensus were further discussed. Four categories were identified as being important when implementing ultrasound ergonomics for BoNT chemodenervation for spasticity; workstation, physician, patient and visual ergonomics. Optimizing ergonomics is paramount when performing US-guided BoNT chemodenervation for spasticity management. This includes proper preparation of the workspace and allowing for sufficient pre-injection time to optimally position both the patient and the physician. Lack of awareness of ergonomics for US-guided BoNT chemodenervation for spasticity may lead to suboptimal patient outcomes, increase work-related injuries, and patient discomfort. We propose key elements for optimal positioning of physicians and patients, as well as the optimal setup of the workspace and provide clinical pearls in visual identification of spastic muscles for chemodenervation.
