ABSTRACT
Background: Osteoarthritis (OA) is the most common and prevalent musculoskeletal disease associated with population aging, negatively impacting function and quality of life. A consequence of knee OA is quadriceps muscle weakness. Musculoskeletal rehabilitation using low load exercises, associated with Blood Flow Restriction (BFR) may be a useful alternative to high load exercises when those cannot be tolerated. Several systematic reviews have reported inconclusive results due to discrepancies in study findings, heterogeneity of results, evaluated time points, and research questions explored. Objective: To perform an overview of systematic reviews with meta-analyses, synthesizing the most recent evidence on the effects of muscle strength training with BFR for knee OA. Methodology: Systematic reviews that include primary controlled and randomized clinical trials will be considered for inclusion. Articles will be considered only if they present a clear and reproducible methodological structure, and when they clearly demonstrate that a critical analysis of the evidence was carried out using instrumented analysis. Narrative reviews, other types of review, overviews of systematic reviews, and diagnostic, prognostic and economic evaluation studies will be excluded. Studies must include adults aged 40 years and older with a diagnosis of knee OA. Two authors will perform an electronic search with guidance from an experienced librarian. The following databases will be searched: PubMed via MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), PEDro, Cumulative Index to Nursing and Allied Health Literature (CINAHL) via EBSCO host, Web of Science, and the gray literature. The search strategy used in the databases will follow the acronym PICOS (population, intervention, comparison, outcome, and study design). Screening (i.e., titles and abstracts) of studies identified by the search strategy will be selected using Rayyan (http://rayyan.qcri.org). The quality assessment will be performed using the "Assessment of Multiple Systematic Reviews" (AMSTAR-2) tool. Systematic Review Registration: PROSPERO, CRD42022367209.
ABSTRACT
Several studies have examined the effect of different types of exercise on people with fibromyalgia. The aim of this study was to identify which dosage of resistance training is effective to reduce pain in women with fibromyalgia. Two authors independently selected studies included in a Cochrane Systematic Review and from an updated search up to May 2021 using the following databases: Embase, Central, Lilacs, PEDro, Current Controlled Trials, and WHO International Clinical Trials Registry Platform, Scopus and ISI Web of Science. Inclusion criteria were randomized clinical trials (RCTs) with female patients (18 years of age or older) diagnosed with fibromyalgia according to the American College of Rheumatology (ACR) criteria and the intervention, resistance exercises for pain reduction. The pain outcome value was extracted from studies for meta-analysis. Nine RCTs were included. Compared to the control groups, resistance exercise groups demonstrated a clinically and statistically significant effect on pain reduction when each exercise was performed in 1-2 sets or 3-5 sets of 4-12 or 5-20 repetitions twice a week, for 8-12 weeks, at intensities of 40-80% with one repetition maximum or perceived exertion. Resistance training exercises are effective to reduce pain in women with fibromyalgia when performed at moderate-to-high intensity in 1-2 sets of 4-20 repetitions twice a week, for 8-12 weeks. The protocol was registered on the International Prospective Register of Systematic Reviews (PROSPERO) platform, CRD42018095205.

OBJECTIVES: To compare amounts of sedentary behavior and physical activity in adults residing in planned group residential settings to those residing in private homes. METHODS: Thirty-one older adults who resided in planned group residential settings (n=13) and in private homes (n=18) participated. Daily activities were measured using the Sensewear Armband for 7 days. Estimates of the duration of daily activities performed across sedentary, light, and moderate-to-vigorous intensities were captured. RESULTS: Participants in planned group residential settings were older (age 85.9±3.5 vs 78.3±7.2; p=0.001) and spent more time in sedentary behaviors (12.7±1.5 vs 11.3±1.6; p=0.02) than participants in private homes. The difference was attenuated slightly after controlling for age and wear time (adjusted difference 1.2±0.6 hours, p=0.06). DISCUSSION: Adults residing in planned group residential settings, which provide supportive services, were more sedentary than adults residing in private homes. The environment in which older adults live may contribute to sedentary behavior.
