RESUMEN
INTRODUCTION AND HYPOTHESIS: Surface electromyography is commonly applied to measure the electrophysiological activity of the neuromuscular system. However, there is no consensus regarding the best protocol to assess pelvic floor muscles. METHODS: A scoping literature review was carried out in six databases, using MeSH descriptors. It included studies with electromyographic assessment in adult women presenting or not with pelvic floor dysfunction. The results were presented in categories to contribute to the development of a protocol considering the most used parameters for non-invasive assessment of myoelectric activity of pelvic floor muscles. RESULTS: A total of 1,074 articles were identified, and 146 studies were selected for analysis. The intravaginal probe was used in 80.8% of the studies, the bipolar sensor with metallic plates placed on both sides of the vagina was the most frequent (71.3%), with a reference electrode positioned on the anterior superior iliac spine (33.5%). The supine position with hip and knee flexed (45.2%) was the most frequent position used. Of the studies, 44.5% normalized the data by maximum voluntary contraction (MVC) whereas 44.5% performed an average of 3 MVCs. CONCLUSIONS: The most frequently used protocol for the pelvic floor is the bipolar intracavitary probe with metal plates positioned at 3-9 o'clock and introduced distally to the vaginal introitus with the volunteer in the supine position and the hip and knee flexed with the reference placed on the anterior-superior iliac spine.

Traumatic brachial plexus injury (BPI) is one of the most disabling injuries of the upper extremity, often requiring specialized treatment and a prolonged rehabilitation period. This scoping review was carried out to identify and describe the physical therapy modalities applied in the rehabilitation of adult individuals with BPI. Electronic databases, gray literature, and reference lists were searched, and studies meeting the following eligibility criteria were included: (a) interventions including any physical therapy modality; (b) individuals age ≥18 years old; and (c) a clinical diagnosis of BPI. The literature search yielded 681 articles of which 49 met the inclusion criteria and had their outcomes, treatment parameters, and the differences between conservative and pre- and postoperative treatment phases analyzed. The most commonly used physical therapy interventions were in the subfields of kinesiotherapy (ie, involving range of motion exercises, muscle stretching, and strengthening), electrothermal and phototherapy, manual therapy, and sensory re-education strategies. Although several physical therapy modalities were identified for the treatment of BPI in this scoping review, the combination of low levels of evidence and the identified gaps regarding the treatment parameters challenge the reproducibility of such treatments in clinical practice. Therefore, future controlled clinical trials with clearer treatment protocols for individuals with BPI are needed.

OBJECTIVE: The objective of this review is to identify the most frequently used protocols for analyzing the myoelectric activity of the pelvic floor muscles during surface electromyography in women aged 18 years or older. INTRODUCTION: Surface electromyography is normally used in assessment and treatment for research purposes when it is intended to quantitatively measure the electrophysiological behavior of the neuromuscular system. However, although there are internationally standardized, non-invasive assessment protocols for most muscle groups, there is no consensus for pelvic floor muscles, which makes it difficult to standardize in scientific research and clinical applicability. INCLUSION CRITERIA: Studies that explore registration protocols and filtering parameters of surface electromyographic signals in women aged over 18 years old with or without pelvic floor dysfunction will be considered. Studies encompassing either electromyographic biofeedback as a treatment resource only or electroneuromyography (needle electrode) will be excluded. METHODS: Primary studies published in the previous 10 years in MEDLINE, Embase, Scopus, Web of Science, CINAHL, and Cochrane Central databases will be included. The search will encompass descriptors registered in MeSH. The identified articles will be assessed for eligibility by two independent reviewers in three stages: evaluation by title, abstract, and full text. If there is any disagreement, a third reviewer will be consulted. Data will be extracted and organized in standardized spreadsheets. The results will be assigned to categories in order to facilitate the organization of a protocol with the most commonly used parameters for non-invasive assessment of myoelectric activity of pelvic floor muscles.
