Clinical trial registration has become more prevalent in physical therapy but it is still inadequate: A meta-research study.

BACKGROUND: A study using data from 2009 showed low prevalence and inadequate trial registration in physiotherapy. In 2013, a joint editorial recommended prospective registration in physiotherapy journals. Ten years later it is unclear whether the joint editorial achieved its intended benefit. OBJECTIVES: To investigate the proportion of randomized trials adequately registered and the extent of selective reporting of outcomes in trials of physiotherapy interventions published in 2019 and to compare these data with equivalent published data from 2009. DESIGN: Meta-research study. METHOD: A random sample of 200 trials published in 2019 was used. Evidence of registration was sought on trial registers and by contacting authors. Data from the article was compared with data from the trial registration. Data from this sample of trial published in 2019 were compared with equivalent published data from 2009. RESULTS: In 2019, the proportion of trials that were registered was 63% versus 34% in 2009 (absolute difference 29%). In 2019, 18% of the trials were prospectively registered compared to 6% in 2009 (absolute difference 12%). Unambiguous primary outcomes (i.e., method and timepoints of measurement clearly defined in the trial registry entry) were registered for 30% in 2019. Registration was adequate (i.e., prospective with unambiguous primary outcomes) for 8%, compared with 3% in 2009 (absolute difference 5%). Selective outcome reporting occurred in 73% of the trials in which it was assessable; in 2009 this proportion was 47% (absolute difference 26%). CONCLUSIONS: Registration of randomized trials in physiotherapy increased in the past decade, but it is still inadequate. More effort is still required to implement and enforce adequate registration.

Falls, muscle strength, and functional abilities in community-dwelling elderly women / Quedas, força muscular e habilidades funcionais em idosas na comunidade

Abstract Introduction: Falls are among the most common and serious problems facing elderly women. Falling is associated with increased mortality, morbidity, reduced functioning, loss of independence and hospitalization. Objective: The aim of this study was to investigate the association among fear of falling, muscle strength, and functional abilities in community-dwelling elderly women. Methods: Forty-nine elderly women (70.57 ± 5.59 years) participated in this study. Records of falls, self-efficacy associated with falls (FES-I Brazil), functional abilities (the Timed Up and Down Stairs test [TUDS] and the Timed Up and Go test [TUG]), lower limb muscle strength (knee extensors and ankle plantar flexors), and hand grip strength were investigated as variables of interest. Descriptive statistics, the one-way ANOVA, and linear regression tests were used to analyze the association between fear of falling and falls with other variables (α = 0.05). Results: Elderly women who presented records of falls within the last year had lesser strength of knee extensors and plantar flexors (p ≤. 05). Those who had low self-efficacy associated with falls presented lower strength of knee extensors (p ≤. 01). Variables associated with functional abilities (r = 0.70) and lower limb strength (r = 0.53) showed a positive correlation (p ≤. 01). Conclusion: The concern with the fear of falling and falls may be negative effects caused by lower limb muscle weakness.

Resumo Introdução: As quedas representam um dos problemas mais comuns e graves enfrentadas por idosas. A queda está associada com o aumento da mortalidade, morbidade, limitação funcional, perda de independência e hospitalização. Objetivo: investigar a associação entre a preocupação com o medo de cair, a força muscular e as habilidades funcionais em idosas residentes na comunidade. Métodos: Participaram deste estudo 49 idosas (70,57 ± 5,59 anos). Como variáveis de interesse foram investigadas: história de quedas, auto eficácia relacionada às quedas (FES-I Brasil), habilidades funcionais (teste cronometrado de subir e descer escadas-TCSDE e Timed Up and Go-TUG), força muscular de membros inferiores (extensores do joelho e flexores plantares do tornozelo) e medida de preensão manual. Estatísticas descritivas, ANOVA One Way e testes de Regressão Linear foram utilizados para analisar as relações entre a preocupação com o medo de cair e quedas com outras variáveis (α = 0,05). Resultados: As idosas que apresentaram histórico de quedas no último ano tinham menor força de extensores do joelho e flexores plantares (p ≤ ,05). E aquelas que tinham uma baixa auto eficácia relacionada com quedas apresentavam força inferior dos extensores do joelho (p ≤ ,01). As variáveis relacionadas com habilidades funcionais (r = ,70) e força de membros inferiores (r = ,53) apresentaram uma relação positiva (p ≤ ,01). Conclusão: A preocupação com o medo de cair e as quedas podem ser efeitos negativos decorrentes de fraqueza muscular de membros inferiores.
