Translation, cross-cultural adaptation and measurement properties of three implementation measures into Brazilian-Portuguese

BACKGROUND

To translate and cross-culturally adapt into Brazilian-Portuguese, and to test the measurement properties of the following items of implementation outcome measures: Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM) and Feasibility of Intervention Measure (FIM).

METHODS

This was a measurement properties study in accordance with the Consensus-based Standards for the selection of health status Measurement Instruments (COSMIN). We conducted a translation and cross-cultural adaptation of three implementation measures according to guidelines for translation and cross-cultural adaptation, then we collected information from patients who had participated in remotely delivered physical therapy treatment for musculoskeletal condition. The patients answered the translated versions of the implementation outcome measures. The measurement properties of the three implementation outcome measures were collected in a test-retest assessment, with an interval of 7 to 14 days.. The measurement properties evaluated in this study were interpretability, measured using Ceiling and Floor Effects, reliability in test-retest evaluation, measured using Cronbach's Alpha Coefficient, internal consistency, measured using Intraclass Correlation Coefficient and construct validity, measured using Pearson Correlation.

RESULTS

We included 104 participants (76 female). The average age of the sample was 56.8 (SD 14.8) years old. The items of implementation outcome measures (AIM, IAM, and FIM) showed 66.39%, 63.11%, and 63.93% of ceiling effects. The items of implementation outcome measures showed adequate internal consistency measured using Cronbach's Alpha Coefficient (AIM: 0.89, IAM: 0.91, FIM: 0.93) and values of Standard Error of Measurement between 5 and 10%, showing good measurement error. The results of AIM and IAM was classified as moderate reliability and the FIM as substantial reliability. In a total 96 correlations, > 75% of correlations met our prior hypothesis.

CONCLUSION

The three Brazilian-Portuguese versions of items of implementation outcome measures had adequate internal consistency, measurement error and construct validity. The three implementation outcome measures showed moderate to substantial reliability values. The Ceiling Effect was observed in the three measures, showing maximum values ​​in more than 15% of the evaluations.

Physical therapists and public perceptions of telerehabilitation: An online open survey on acceptability, preferences, and needs

BACKGROUND

During the COVID-19 pandemic, telerehabilitation allowed the continuation of physical therapy care in parallel with public health measures to prevent the virus spread. However, in low- and middle-income countries including Brazil, telerehabilitation was unfamiliar to most of the population.

OBJECTIVE

To investigate acceptability, preferences, and needs in telerehabilitation by Brazilian physical therapists and the general population.

METHODS

We conducted an observational cross-sectional study with an online survey consisting of 13 multiple-choice items. Items were distributed among acceptability, preferences, and needs sections, and encompassed confidence in delivering or receiving telerehabilitation, its perceived efficacy and costs, and suitable content.

RESULTS

A total of 1107 responses were registered, 717 from physical therapists. Half of them self-reported confidence in conducting telerehabilitation through the internet (synchronous or asynchronous). The same proportion disagreed that telerehabilitation is as effective as in-person interventions. Physical therapists agreed telerehabilitation should contain educational, self-management strategies, and exercises information, but the general population endorsed the provision of technical advice on exercise execution. The general population mostly reported that telerehabilitation could help their specific health condition (86%), but only 14% of respondents would pay the same as they pay for in-person consultations. Participants reported an overall preference for synchronous communication and concern about the lack of a hands-on approach.

CONCLUSION

Physical therapists and the general population appear to demonstrate apprehension towards telerehabilitation. Insufficient preparation or inadequate knowledge might influence participants' acceptance, preferences, and needs.

Choosing Wisely Brazil: top 5 low-value practices that should be avoided in musculoskeletal physical therapy

BACKGROUND

The Choosing Wisely initiative aims to promote discussions among healthcare professionals and patients about low-value, or potentially harmful, health practices.

OBJECTIVES

To describe the process of development of the Brazilian Choosing Wisely list for musculoskeletal physical therapy.

METHODS

The Brazilian Choosing Wisely list was developed in accordance with the recommendations of the American Board of Internal Medicine. A three-step procedure was used. First, an expert panel was selected, and a modified Delphi approach was used to obtain a list of evidence-based statements. Second, members of the research team performed content analysis. Third, a national survey was conducted to present selected statements to a sample of physical therapists. Participants were invited to vote considering the level of importance of selected statements for physical therapists and patients.

RESULTS

The expert panel comprised 17 physical therapists. The median age of the expert panel was 33 [interquartile range (IQR) 29 to 37; range 26 to 60] years and the median length of professional experience was 12 (IQR 10 to 18) years. A list of eight recommendations was presented to a national sample composed of 1127 physical therapists. The median length of professional experience of the national sample was 10 (IQR 5 to 15) years. Based on the number of votes, the five most important recommendations were included in the Brazilian Choosing Wisely list for musculoskeletal physical therapy. Descriptive and frequency analysis were used to report the results.

CONCLUSION

The Brazilian Choosing Wisely list for musculoskeletal physical therapy provides an opportunity for physical therapists, patients, society and policy makers to collaboratively discuss tests and treatments that are unnecessary or potentially harmful.

The influence of fatigue in evertor muscles during lateral ankle sprain

Ankle sprain in plantarflexion and inversion is one of the most common injuries occurring in daily activities and sports. Although acute symptoms may resolve quickly, many individuals have reported persistent pain and instability. Thus, understanding the factors that contribute to the occurrence of this type of injury is extremely important. Although sprains are multifactorial, a relationship can be established between sprain and fatigue. Therefore, the present study examined the latency and intensity of activation of the peroneus longus and brevis muscles under conditions of fatigue. Twenty-three women participated in the study, including 12 with functional instability of the ankle and 11 without a history of sprain. To induce fatigue, the volunteers maintained the force of eversion and plantarflexion at 70% of the maximum voluntary isometric contraction for as long as possible until a 10% decline in the rated force occurred. Ten simulations of ankle sprains were performed before and after fatigue at random for each side, with simultaneous recordings of the electromyographic signals, using a simulator platform for inversion sprain and plantarflexion. As a result, after fatigue, no change in latency was observed. However, a reduction in the intensity of contraction of the muscles analyzed in both groups was observed. Neuromuscular control was concluded to be compromised in situations of fatigue, while differences in muscle behavior were not observed between stable and unstable ankles.

PAX8-PPARgamma rearrangement is frequently detected in the follicular variant of papillary thyroid carcinoma

CONTEXT

The clinicopathological characteristics and the molecular features of the follicular variant of papillary thyroid carcinoma (FVPTC) remain controversial.

OBJECTIVE/DESIGN/PATIENTS

In an attempt to clarify such controversies and to find whether or not FVPTC cases share the molecular features of follicular tumors, we searched for the presence of PAX8-PPARgamma rearrangements, RAS mutations, and RAP-1, RAF-1, and BRAF mutations in a series of 40 FVPTCs as well as in 27 follicular thyroid carcinomas (FTCs) and 12 follicular thyroid adenomas (FTAs). Fluorescence in situ hybridization and RT-PCR were used to detect the PAX8-PPARgamma rearrangement and PCR, single strand confirmational polymorphism, and sequencing for searching the mutations.

RESULTS

The frequency of PAX8-PPARgamma rearrangement was similar in FVPTCs (37.5%), FTCs (45.5%), and FTAs (33.3%). The same holds true regarding the frequency and type of RAS mutations: FVPTC, 25.0%; FTC, 22.2%; and FTA, 33.3%. BRAF mutations were only detected in FVPTC (10%); the BRAF mutations in these cases (K601E and G474R) are different from the typical BRAF(V600E) mutation of conventional PTCs. No mutations were detected in RAP-1 and RAF-1. In FVPTCs, the PAX8-PPARgamma rearrangement was significantly associated with multifocality and vascular invasion, whereas the RAS mutations were significantly associated with the large tumor size. There were three cases of FVPTC, three FTCs and one FTA, harboring both PAX8-PPARgamma rearrangement and RAS mutations; patients with such tumors were usually very young.

CONCLUSIONS

We conclude that a subset of FVPTC shares some of the molecular features of follicular tumors. Further studies are necessary to clarify the putative clinical significance (e.g. association to blood-born metastases) of PAX8-PPARgamma rearrangement, RAS mutations, and BRAF(K601E) in FVPTCs.
