BackgroundThe evaluation of competencies in the clinical field is essential for health professionals, as it allows the acquisition of these competencies to be tracked. The objective of this study was to create and evaluate the validity and reliability of a tool for measuring clinical competencies in physical therapy (PT) students to assess the quality of their performance in a professional context.MethodsA descriptive study was designed. The Measurement Tool for Clinical Competencies in PT (MTCCP) was developed based on the evaluation of 39 experts: 15 clinicians and 24 instructors. The content validity was evaluated using the Content Validity Index (CVI). Three professors were invited to apply the tool to 10 students. Cronbach’s alpha, exploratory factor analysis, and the intraclass correlation coefficient were used to determine the reliability and validity of the scale.ResultsThe CVI was positive—higher than 0.8. Principal component analysis confirmed the construct validity of the tool for two main factors: clinical reasoning (first factor) and professional behavior (second factor). With regard to reliability, the MTCCP achieved an internal congruence of 0.982. The inter-evaluator reproducibility for clinical reasoning, professional behavior, and the total MTCCP score was almost perfect; the ICCs were 0.984, 0.930, and 0.983, respectively.ConclusionsThe MTCCP is a valid and reliable instrument for assessing the performance of PT students in hospital settings and can be used to determine what skills students feel less confident using and what additional training/learning opportunities could be provided. Further research is needed to determine whether the MTCCP has similar validity and reproducibility in other Spanish-speaking national and international PT programs.Electronic supplementary materialThe online version of this article (10.1186/s12909-018-1377-x) contains supplementary material, which is available to authorized users.
An increase in altitude leads to a proportional fall in the barometric pressure, and a decrease in atmospheric oxygen pressure, producing hypobaric hypoxia that affects, in different degrees, all body organs, systems and functions. The chronically reduced partial pressure of oxygen causes that individuals adapt and adjust to physiological stress. These adaptations are modulated by many factors, including the degree of hypoxia related to altitude, time of exposure, exercise intensity and individual conditions. It has been established that exposure to high altitude is an environmental stressor that elicits a response that contributes to many adjustments and adaptations that influence exercise capacity and endurance performance. These adaptations include increase in hemoglobin concentration, ventilation, capillary density and tissue myoglobin concentration. However, a negative effect in strength and power is related to a decrease in muscle fiber size and body mass due to the decrease in the training intensity. Many researches aim at establishing how training or living at high altitudes affects performance in athletes. Training methods, such as living in high altitudes-training low, and training high-living in low altitudes have been used to research the changes in the physical condition in athletes and how the physiological adaptations to hypoxia can enhance performance at sea level. This review analyzes the literature related to altitude training focused on how physiological adaptations to hypoxic environments influence performance, and which protocols are most frequently used to train in high altitudes.
The protocol established for taking hand grip dynamometry measurements determines that the patient must be in a sitting position. This protocol cannot be applied due to the patient’s conditions in some cases, such as abdominal surgery, musculoskeletal spine or hip injuries. The purpose was to determine the reproducibility and level of agreement between the Handgrip dynamometry in supine position with the elbow flexed or extended, and the one measured in the sitting position, the design was a descriptive cross-sectional study. The population were young apparently healthy between 18 and 30 years of age (N = 201). Handgrip measurement was performed on both upper limbs in a sitting position with a flexed elbow, a supine position with a flexed elbow, and supine position with the elbow extended. Reproducibility was nearly perfect in all positions (ICC 0.95–0.97). Regarding the level of agreement for the comparison between sitting and supine positions with a flexed elbow, an average difference of − 0.406. For supine position with an extended elbow and supine position with a flexed elbow, the average difference was − 1.479. Considering the results, clinicians or researchers can choose any of the positions evaluated herein and obtain reliable results as long as the standardization process is followed.
The effects and the prescription parameters of therapeutic exercise are not clear. For this reason, is needed to determine the effect of neuromuscular exercise on balance, muscle strength and flexibility specifying the parameters and characteristics of effective interventions in children between 6 and 12 years and adolescent between 13 and 18 years with Down Syndrome. The present study is a systematic review of effectiveness outcomes balance, muscle strength and flexibility in this population. The databases of PubMed, PEDro, EMBASE, SCIELO, Lilacs, Cochrane library were searched from May to December 2021. We recruited randomized controlled trials (RCTs) which met the inclusion criteria in our study. Ten studies were included. The interventions included mechanotherapy, vibration, and use of different unstable surfaces. The exercise frequency ranged from 3 to 5 days a week, and the duration of each session was between six and 15 min. The frequency was between two and three times a week for 6 and 12 weeks and the intensity were between 60 and 80% of maximal voluntary contraction. Neuromuscular exercise in different modes of application was associated with increases in chest and lower limb muscle strength mean 8.51, CI [2.35–14.67] kg and (21.54 [1.64, 41.43]) kg. Balance also improved when the mode of application was isokinetic training and core stability exercises (− 0.20 [− 0.29, − 0.12]) evaluated with stability index. Neuromuscular exercise appears to be effective for the improvement of both lower limb and chest muscle strength and balance in children over 8 years. No evidence was found in children under 8 years.
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.
