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.

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.
