Chronic obstructive pulmonary disease (COPD) is a systemic disease with multiple extrapulmonary manifestations including impeded skeletal muscle function, leading to decreased muscular strength and endurance in patients with COPD. Pulmonary rehabilitation eases the symptoms of the condition and produces increased muscular endurance. Neuromuscular electrical stimulation (NMES) may serve as a treatment alternative to traditional pulmonary rehabilitation. The aim of the study was to assess the effects of NMES combined with pulmonary rehabilitation on exercise tolerance in patients in comparison with pulmonary rehabilitation alone. The subjects included 30 patients with COPD randomly assigned to one of the two groups. The first group consisted of 15 patients who were treated with neuromuscular electrical stimulation at frequency of 35Hz and pulmonary rehabilitation (NMES+RP). The second group comprised 15 patients treated with pulmonary rehabilitation only (RP). Pre- and poststudy assessments were performed. The retrospective evaluation including an exercise tolerance test (i.e. six minute walk test (6MWT)), spirometry and blood gasometry was carried out after 3 weeks. Twenty-eight patients in total completed the study. In the NMES+RP group, an increase in exercise tolerance manifested by a longer distance walked in the 6MWT was observed in comparison to the pulmonary rehabilitation group. No effects of NMES combined with pulmonary rehabilitation on selected spirometric and gasometric parameters in patients with COPD were observed in comparison with traditional pulmonary rehabilitation. The acquired results suggest that NMES of the lower limbs may be applied as an additional form of pulmonary rehabilitation in patients with COPD.
Increasing physical activity is a widely-known method of rehabilitation of patients with chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD). However, what kind of procedure is to be applied if a patient suffers from advanced heart or respiratory failure, cannot undertake physical exercise due to locomotor system disorders or is currently undergoing respiratorotherapy? Recent research shows that neuromuscular electrical stimulation of the lower limb skeletal muscles (NMES) may comprise an alternative to physical training in patients with CHF and COPD. The aim of this study is to summarize the current state of knowledge on the use of NMES in cardiac rehabilitation of patients with CHF and pulmonary rehabilitation of patients with COPD. As demonstrated in recent research on the topic, NMES -due to forcing the muscles to activate -increases exercise tolerance, muscle mass and endurance in patients with CHF and COPD. The beneficial effect of NMES on blood circulation in the muscles, aerobic enzymes activity, functioning of the vascular endothelium, reduction of pro-inflammatory cytokines concentration and increased quality of life has also been presented. It is to be accentuated that NMES treatment, due to lesser physical exertion and, in turn, a decreased feeling of dyspnea are more comfortable for the patient than traditional physical training. Moreover, NMES treatment, after foregoing training, can be applied at home. Potential side effects include transient muscle pain and minor skin damage due to improper positioning of the electrodes. To summarize, NMES treatment is well received by CHF and COPD patients and brings about increased exercise tolerance, as well as better quality of life. Devices used for NMES therapy, due to progressive miniaturization, are easily accessible and relatively inexpensive.
Review question / Objective: The scoping review aims to identify publications describing the measurement of inter-recti distance (IRD)/diastasis recti abdominis (DRA) using ultrasonographic imaging (USI). The identification is based on the population/concept/context (PCC) framework that concerns human adults that underwent IRD/linea alba width/DRA measurement with USI for physiotherapy/physical exercise purposes. Based on systematically mapped peer-reviewed studies it is aimed to perform data extraction and synthesis of specific aspects of the IRD measurement procedure and discuss their similarities and differences. Related to that the attempt will be made to formulate recommendations on the IRD measurement procedure, which might be considered in future physiotherapy studies and practice. The recommendations will be made based on the synthesis of the results in light of existing literature and as the result of discussions and consensus between the authors (coming from three research centers).
Background Inter-recti distance (IRD) measurement using musculoskeletal USI has been used in physiotherapy research, in particular, to investigate pregnancy-related diastasis recti abdominis (DRA) and to seek its effective treatment methods. Severe and untreated diastasis may result in the formation of umbilical or epigastric hernias. Objective This study aimed to systematically map physiotherapy-related research articles that included descriptions of IRD measurement procedures using USI to present their similarities and differences, and formulate recommendations on the procedure. Design A scoping review was conducted according to PRISMA-ScR guidelines, including 49 of 511 publications from three major databases. Publications were selected and screened by two independent reviewers whose decisions were consulted with a third reviewer. The main synthesized data items were: the examinees’ body position, breathing phase, measurement sites, and DRA screening methods. The final conclusions and recommendations were the result of a consensus between seven reviewers from four research centers. Results Studies used 1–5 measurement sites that were differently determined. IRD was measured at the umbilicus (n = 3), at its superior (n = 16) and/or inferior border (n = 9), and at different levels: between 2 and 12 cm above the umbilicus, or a third of the distance and halfway between the umbilicus and xiphoid (n = 37); between 2 and 4.5 cm below the umbilicus or halfway between the umbilicus and pubis (n = 27). Different approaches were used to screen subjects for DRA. Conclusions The discrepancies between the measurement procedures prevent between-study comparisons. The DRA screening method should be standardized. IRD measurement protocol standardization has been proposed. Critical relevance statement This scoping review indicates that the inter-recti distance measurement procedures using ultrasound imaging differ between studies, preventing between-study comparisons. Based on the results synthesis, the measurement protocol standardization has been proposed. Key points The inter-recti distance measurement procedures using USI differ between studies. Proposed standardization concerns body position, breathing phase, measurements number per location. Determination of measurement locations considering individual linea alba length is suggested. Recommended locations: umbilical top, ½ of umbilical top-xiphoid, ¼ of umbilical top-xiphoid/pubis distances. Diastasis recti abdominis diagnostic criteria are needed for proposed measurement locations. Graphical Abstract
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.
