- Analysis of Portuguese physiotherapists’ self-knowledge on temporomandibular disordersPublication . Moleirinho-Alves, Paula; Cebola, Pedro; Melo, Xavier; Simões, Sérgio; Godinho, CatarinaBackground: Physiotherapy is one of the most referenced and effective conservative strategies for treating patients with temporomandibular disorders (TMD). This study aimed to characterize and analyze the self-knowledge of TMD of Portuguese physiotherapists. Methods: an online questionnaire was carried out, and the data collected were descriptively analyzed. Results: A total of 338 physiotherapists participated, of which only 142 treated patients with TMD. Seventy-six percent of the physiotherapists reported that they had not received training in the TMD area during the physiotherapy degree course. Only 11% of the physiotherapists reported that treating patients with TMD adequately identified all symptoms of TMD. Conclusions: the present study showed that it is necessary to integrate TMD-related content into the basic training of physiotherapists and promote an increase in evidence-based training.
- Arterial stiffness following endurance and resistance exercise sessions in older patients with coronary artery diseasePublication . Santos, Vanessa; Massuça, Luís Miguel; Angarten, Vitor; Melo, Xavier; Pinto, Rita; Fernhall, Bo; Santa-Clara, HelenaArterial stiffness (AS) is associated with coronary artery disease (CAD). Acute endurance training decreases AS, whereas acute resistance training increases it. However, these results are from studies in apparently healthy adults, and there is no information on the effects of such afterload AS in elderly patients with CAD. We aimed to investigate the effect of acute endurance or resistance training on the time course of changes in the indices of AS in elderly patients with CAD in order to understand how stiffness responds after training. We tested 18 trained men with CAD. AS was measured using central and peripheral pulse wave velocity (PWV) after 15 min of rest and after 5, 15, and 30 min of endurance and resistance training sessions. The endurance session consisted of high-intensity interval walking at 85–90% of maximum heart rate, and the resistance session consisted of 70% of the maximum of one repetition. An interaction effect was found for central and peripheral PWV (p ≤ 0.001; carotid, η2 = 0.72; aortic, η2 = 0.90; femoral, η2 = 0.74), which was due to an increase in PWV after resistance and a decrease in central and peripheral PWV after endurance. This study demonstrates that training mode influences the time course of AS responses to acute exercise in these patients. Acute endurance training decreased AS, whereas resistance training significantly increased it.
- Arterial stiffness response to acute combined training with different volumes in coronary artery disease and heart failure patientsPublication . Santos, Vanessa; Massuça, Luís Miguel; Angarten, Vítor; Melo, Xavier; Pinto, Rita; Fernhall, Bo; Santa-Clara, HelenaResistance training has been shown to acutely increase arterial stiffness (AS), while endurance training appears to decrease AS. However, the findings are from studies in apparently healthy subjects and have limited applicability to patients at low and high cardiovascular risk, for whom combined exercise is recommended. We compared the time course of changes in local and regional indices of AS in response to high-volume combined endurance training (CET) and high-volume combined resistance training (CRT) in patients with coronary artery disease (CAD) and heart failure (HF). We studied 20 men with CAD and HF (10 each) aged 68.3 ± 9.6 years. AS was measured by pulse wave velocity (PWV), and brachial and central blood pressure (BP) were determined after 15 min of rest and 5 and 15 min after the exercise session. All patients completed two sessions on nonconsecutive days. A protocol by time interaction effect was observed for carotid (η2 = 0.21, p = 0.02), aortic (η2 = 0.60, p < 0.001), and femoral (η2 = 0.46, p = 0.01) PWV after CET and CRT, suggesting that PWV decreased after CET and increased after CRT. Decreases in the brachial and central variables of BP across time points were observed in both protocols. CET decreased whereas CRT increased carotid, aortic, and femoral PWV at 15 min after exercise in patients with CAD and HF.
