Our results indicate that ultrasonography is informative and accurate for the detection of clinical medial epicondylitis. Therefore, ultrasonography should be considered as an initial imaging method for evaluating medial epicondylitis.
ObjectiveTo investigate the therapeutic effect of extracorporeal shockwave therapy (ESWT) according to treatment session on gastrocnemius muscle spasticity in children with spastic cerebral palsy (CP).MethodsTwelve children with spastic CP underwent 1 ESWT and 2 sham ESWT sessions for gastrocnemius (group 1) or 3 ESWT sessions (group 2) once per week for 3 weeks. Modified Ashworth Scale (MAS) score, passive range of motion (PROM) of the ankle plantar-flexor muscles with knee extension, and median red pixel intensity (RPI) of color histogram of medial gastrocnemius on real-time sonoelastography (RTS) were measured before ESWT, immediately after the first and third ESWT, and at 4 weeks after the third ESWT.ResultsMean ankle PROM was significantly increased whereas as mean ankle MAS and median gastrocnemius RPI were significantly decreased in both groups after the first ESWT. Clinical and RTS parameters before ESWT were not significantly different from those immediately after the third ESWT or at 4 weeks after the third ESWT in group 1. However, they were significantly different from those immediately after the third ESWT or at 4 weeks after the third ESWT in group 2. Mean ankle PROM, mean ankle MAS, and median gastrocnemius RPI in group 2 were significantly different from that in group 1 at 4 weeks or immediately after the third ESWT.ConclusionThe therapeutic effect of ESWT on spastic medial gastrocnemius in children with spastic CP is dependent on the number of ESWT sessions.
Metabolomics uses quantitative analyses of metabolites from tissues or bodily fluids to acquire a functional readout of the physiological state. Complex diseases arise from the influence of multiple factors, such as genetics, environment and lifestyle. Since genes, RNAs and proteins converge onto the terminal downstream metabolome, metabolomics datasets offer a rich source of information in a complex and convoluted presentation. Thus, powerful computational methods capable of deciphering the effects of many upstream influences have become increasingly necessary. In this review, the workflow of metabolic marker discovery is outlined from metabolite extraction to model interpretation and validation. Additionally, current metabolomics research in various complex disease areas is examined to identify gaps and trends in the use of several statistical and computational algorithms. Then, we highlight and discuss three advanced machine-learning algorithms, specifically ensemble learning, artificial neural networks, and genetic programming, that are currently less visible, but are budding with high potential for utility in metabolomics research. With an upward trend in the use of highly-accurate, multivariate models in the metabolomics literature, diagnostic biomarker panels of complex diseases are more recently achieving accuracies approaching or exceeding traditional diagnostic procedures. This review aims to provide an overview of computational methods in metabolomics and promote the use of up-to-date machine-learning and computational methods by metabolomics researchers.
Phantom limb pain (PLP) is a significant source of chronic pain in most persons with amputation at some time in their clinical course. Pharmacologic therapies for this condition are often only moderately effective and may produce unwanted adverse effects. There is growing empirical evidence of the therapeutic effectiveness of mind-body therapies for the relief of chronic pain; therefore, an exploration of their role in relieving amputation-related chronic pain is warranted. We undertook a focused literature review on mind-body interventions for patients with amputation who experience PLP. Because of study heterogeneity, only descriptive presentations of the studies are presented. Only studies of hypnosis, imagery, and biofeedback, including visual mirror feedback, were found; studies on meditation, yoga, and tai chi/qigong were missing from the literature. Few studies of specific mind-body therapies were dedicated to management of PLP, with the exception of mirror visual therapy. Overall, studies were largely exploratory and reflect considerable variability in the application of mind-body techniques, making definitive conclusions inadvisable. Nevertheless, the weight of existing findings indicates that a mind-body approach to PLP pain management is promising and that specific methods may offer either temporary or long-term relief, either alone or in combination with conventional therapies. The authors discuss the potential for usefulness of specific mind-body therapies and the relevance of their mechanisms of action to those of PLP, including targeting cortical reorganization, autonomic nervous system deregulation, stress management, coping ability, and quality-of-life. The authors recommend more and better quality research exploring the efficacy and mechanisms of action.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
