Isokinetic ankle muscle strength is reduced in recreational runners with medial tibial stress syndrome and is not associated with pain

Abstract Aim: The purpose of this study was to investigate the strength and ratios of the plantar flexors and ankle dorsiflexors in recreational runners with medial tibial stress syndrome and to assess the association between muscle strength and the level of pain in this population. Methods: Two groups (control and medial tibial stress syndrome) of eighteen runners each participated in this cross-sectional study. Isokinetic dynamometry was used to evaluate muscle strength, and for the analysis, the normalized isokinetic peak torque controlled by gender was used. Results: The medial tibial stress syndrome group showed lower normalized isokinetic peak torque in the dorsiflexors in the concentric (p = 0.008) eccentric (p = 0.011) contraction, as well as a lower plantar flexor, normalized isokinetic peak torque in the concentric (p = 0.001) and eccentric (p = 0.02) when compared to the control group. However, there was no difference in the normalized isokinetic peak torque ratio representative of the stance (p = 0.62) and swing phase (p = 0.16), and the level of pain was not correlated with the strength concentric (p = 0.32) and eccentric (p = 0.621) of plantar flexors, nor to the concentric (p = 0.21) and eccentric of dorsiflexors (p = 0.54). Conclusion: Recreational runners with MTSS showed decreased muscle strength in the sagittal plane of the ankle, no correlation with the level of pain, and no changing the ratio between plantar flexors and dorsiflexors.

Síndrome da fragilidade em idosos com diabetes mellitus tipo 2 / Frailty syndrome in elderly patients with type 2 diabetes mellitus

Objetivo Conhecer a prevalência da síndrome da fragilidade em idosos com diabetes mellitus tipo 2. Métodos Estudo transversal que incluiu 30 idosos, de ambos os sexos, com idades entre 60 a 79 anos e diagnóstico de diabetes mellitus tipo 2. Os instrumentos de pesquisa foram validados para língua portuguesa e incluíram variáveis sociodemográficas, clínicas e critérios para síndrome da fragilidade. Os idosos foram divididos em frágil, pré-frágil e não frágil. Os dados foram analisados por estatística descritiva. Resultados A prevalência da fragilidade foi de 56,7%. Os fatores associados foram: sexo feminino (70,6%); viúvos (69,2%); cor branca (58,8%); não trabalhar (69,2%); e tempo de diagnóstico de 25 a 48 meses (47,1%). Conclusão Os fatores associados, tais como, sociodemográficos, econômicos e tempo de diagnóstico não interferiram na prevalência da síndrome da fragilidade em idosos com diabetes mellitus tipo 2.

Objective To determine the prevalence of frailty syndrome in elderly patients with type 2 diabetes mellitus. Methods Cross-sectional study including 30 elderly of both genders, aged 60-79 years, and diagnosed with type 2 diabetes mellitus. The research instruments were validated for Portuguese, included sociodemographic and clinical variables, and criteria for frailty syndrome. The elderly were divided into frail, pre-frail and non-frail. Data were analyzed using descriptive statistics. Results The prevalence of frailty was 56.7%. The associated factors were the following: female gender (70.6%); widowed (69.2%); white color (58.8%); not working (69.2%); and time since diagnosis of 25-48 months (47.1%). Conclusion The associated factors such as sociodemographic, economic and time since diagnosis did not affect the prevalence of frailty syndrome in elderly patients with type 2 diabetes mellitus.
