Rating of perceived exertion on loading control of resistance exercises during rehabilitation of knee dysfunctions
Rating of perceived exertion, intensity, resistance exercise, rehabilitation, anterior cruciate ligament, knee osteoarthritis
Anterior cruciate ligament (ACL) rupture and knee osteoarthritis (KOA) are the most prevalent musculoskeletal disorders of the knee. Rehabilitation with progressive training is recommended for both disorders. Rating of perceived effort (RPE) is used to prescribe, assess, and control exercise load. However, the lack of detailed methodological description and the variability in the use of the PSE may hamper its validity. This review summarizes the methodological aspects of using RPE in resistance exercise during ACL maintenance and KOA rehabilitation. This scoping review was developed following the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Statement for Scoping Reviews extension. The search was performed in Medline/PubMed, Embase, CINAHL, PEDro, Central and SPORTDiscus databases. The terms “rehabilitation of the anterior cruciate ligament of the knee”, “osteoation of the cruciate ligament arthrosis- Two review reviewers are independent in the selection of titles and evaluation titles and evaluation of independent full-text manuscripts. Data related to study design, sample, intervention characteristics and RPE results were extracted, summarized and qualitatively. Methodological aspects such as “scale type”, “terms” and “exercise intensity” are frequently reported (75%-87% of studies). However, “familiarization”, “anchoring”, “instructions”, “estimate x production paradigm”, “local x global PSE” and the “registration moment” are poorly known (maximum of 22% of the studies). The description of the use of RPE in ACL-R and KOA rehabilitation studies is poor. Methodological aspects should be better reported to ensure standardization, improve the validity of the scale and allow for the reproduction of the study.
