Résumé : Objective
To analyze the acute hemodynamic effects of adding virtual realitybased therapy (VRBT) using exergames for patients undergoing cardiac rehabilitation (CR).
Outpatient rehabilitation center.
Patients (N=27) with a diagnosis of cardiovascular disease or cardiovascular risk factors. Mean age (years) ± SD was 63.4±12.7 and mean body mass index (kg/m2) ± SD was 29.0±4.0.
Patients performed 1 VRBT session and 1 CR session on 2 nonconsecutive days. Each session comprised an initial rest, warm-up, conditioning, and recovery. During warm-up, in the VRBT session, games were performed with sensors to reproduce the movements of avatars and, in the CR session, patients were required to reproduce the movements of the physiotherapists. In the conditioning phase for VRBT, games were also played with motion sensors, dumbbells, and shin guards. The CR session consisted of exercises performed on a treadmill. The intensity of training was prescribed by heart rate reserve (HRR; 40%-70%).
Main Outcome Measures
The primary outcomes were heart rate, blood pressure, respiratory rate (RR), rating of perceived exertion (RPE), and peripheral oxygen saturation, evaluated before, during, and after the VRBT or CR session on 2 nonconsecutive days. The secondary outcome was to evaluate whether the patients achieved the prescribed HRR and the percentage of time they maintained this level during the VRBT session.
VRBT produces a physiological similar pattern of acute hemodynamic effects in CR. However, there was greater magnitude of heart rate, RR, and RPE (P<.01 during the execution of vrbt and until minutes recovery observed at moments rest recovery.> Conclusions
Although the VRBT session produces similar physiological acute hemodynamic effects in CR, greater magnitudes of heart rate, RR, and RPE were observed during its execution and up to 5 minutes after the session.

Résumé : Objectives: The association between hearing loss and risk factors for cardiovascular disease, including high blood pressure (BP), has been evaluated in numerous studies. However, data from population- and laboratory-based studies remain inconclusive. Furthermore, most prior work has focused on the effects of BP level on behavioral hearing sensitivity. In this study, we investigated cochlear integrity using distortion product otoacoustic emissions (DPOAEs) in persons with subtle elevation in BP levels (nonoptimal BP) hypothesizing that nonoptimal BP would be associated with poorer cochlear function.
Design: Sixty individuals [55% male, mean age = 31.82 (SD = 11.17) years] took part in the study. The authors measured pure-tone audiometric thresholds from 0.25 to 16 kHz and computed four pure-tone averages (PTAs) for the following frequency combinations (in kHz): PTA0.25, 0.5, 0.75, PTA1, 1.5, 2, 3, PTA4, 6, 8, and PTA10, 12.5, 16. DPOAEs at the frequency 2f1-f2 were recorded for L1/L2 = 65/55 dB SPL using an f2/f1 ratio of 1.22. BP was measured, and subjects were categorized as having either optimal BP (systolic/diastolic =120 or diastolic >=80 mm Hg or use of antihypertensives). Between-group differences in behavioral thresholds and DPOAE levels were evaluated using 95% confidence intervals. Pearson product-moment correlations were run to assess the relationships between: (1) thresholds (all four PTAs) and BP level and (2) DPOAE [at low (f2 2 kHz and 10 kHz) frequency bins] and BP level. Linear mixed-effects models were constructed to account for the effects of BP status, stimulus frequency, age and sex on thresholds, and DPOAE amplitudes.
Results: Significant positive correlations between diastolic BP and all four PTAs and systolic BP and PTA0.25, 0.5, 0.75 and PTA4, 6, 8 were observed. There was not a significant effect of BP status on hearing thresholds from 0.5 to 16 kHz after adjustment for age, sex, and frequency. Correlations between diastolic and systolic BP and DPOAE levels were statistically significant at the high frequencies and for the relationship between diastolic BP and DPOAE level at the mid frequencies. Averaged across frequency, the nonoptimal BP group had DPOAE levels 1.50 dB lower (poorer) than the optimal BP group and differences were statistically significant (p = 0.03).
Conclusions: Initial findings suggest significant correlations between diastolic BP and behavioral thresholds and diastolic BP and mid-frequency DPOAE levels. However, adjusted models indicate other factors are more important drivers of impaired auditory function. Contrary to our hypothesis, we found that subtle BP elevation was not associated with poorer hearing sensitivity or cochlear dysfunction. We consider explanations for the null results. Greater elevation in BP (i.e., hypertension itself) may be associated with more pronounced effects on cochlear function, warranting further investigation. This study suggests that OAEs may be a viable tool to characterize the relationship between cardiometabolic risk factors (and in particular, stage 2 hypertension) and hearing health

Mots-clés : Blood pressure orthostatic Résumé : Objective
To investigate the relationship between orthostatic hypotension (OH) and muscle strength versus time to successful rehabilitation within elderly patients with hip fracture.
A prospective, observational cohort study. Handgrip strength was measured at the day of admission and OH as soon as possible after surgery. Cox proportional hazard modeling was used to investigate the relationship between OH or handgrip strength (kg) and time to successful rehabilitation, expressed as hazard ratios (HRs). OH was defined as a decrease in systolic blood pressure of ≥20mmHg or diastolic blood pressure of ≥10mmHg after postural change (dichotomous). Handgrip strength was measured with a hand dynamometer (continuous).
Patients (N=116) aged ≥70 years with a hip fracture were recruited on the day of hospital admission.
Main Outcome Measures
Primary outcome was time to successful rehabilitation, which was defined as discharge to patients' own homes.
During a median follow-up period of 36 days (interquartile range, 957d), 103 patients (89%) were successfully rehabilitated. No statistically significant relationships were found between OH and time to successful rehabilitation (HR=1.05; 95% confidence interval [CI], .671.66). Also, handgrip strength and successful rehabilitation were not statistically significantly related (HR=1.03; 95% CI, .991.06).
OH measured during the first days of hospitalization is not related to time to successful rehabilitation in patients with hip fracture who have undergone surgery. Although no significant relationship was seen in the present study, the width of the CIs does not exclude a relevant relationship between handgrip strength and time to successful rehabilitation.

Mots-clés : syndrome central de la moelle Résumé : "Objective
To examine cardiovascular (CV) health in a large cohort of individuals with incomplete spinal cord injury (SCI). The CV health parameters of patients were compared based on American Spinal Injury Association Impairment Scale (AIS), neurologic level, sex, central cord syndrome, age, time since injury, Neuromuscular Recovery Scale, and total AIS motor score.
Seven outpatient rehabilitation clinics.
Individuals (N=350) with incomplete AIS classification C and D were included in this analysis.
Main Outcome Measures
Heart rate, systolic and diastolic blood pressure during resting sitting and supine positions and after an orthostatic challenge.
CV parameters were highly variable and significantly differed based on patient position. Neurologic level (cervical, high and low thoracic) and age were most commonly associated with CV parameters where patients classified at the cervical level had the lowest resting CV parameters. After the orthostatic challenge, blood pressure was highest for the low thoracic group, and heart rate for the high thoracic group was higher. Time since SCI was negatively related to blood pressure at rest but not after orthostatic challenge. Men exhibited higher systolic blood pressure than women and lower heart rate. The prevalence of orthostatic hypotension (OH) was 21% and was related to the total motor score and resting seated blood pressures. Cervical injuries had the highest prevalence.
Resting CV parameters of blood pressure and heart rate are affected by position, age, and neurologic level. OH is more prevalent in cervical injuries, those with lower resting blood pressures and who are lower functioning. Results from this study provide reference for CV parameters for individuals with incomplete SCI. Future research is needed on the impact of exercise on CV parameters."

Résumé : Introduction
The aim of this study was to determine the effect of music therapy on patients suffering dental anxiety. In addition, a second objective was to determine the correlation between salivary cortisol and other physiologic parameters.
34 patients were randomly assigned to the control group and the experimental group. For each patient was measured for salivary cortisol, stimulate salivary flow, blood pressure, heart rate, oxygen saturation and body temperature. Student t-test and Chi2 were applied to analyze significant differences between the studied variables before and after the unpleasant stimulation causes anxiety for dental treatment.
Initially, both groups registered the same level of anxiety. In the second measurement, significant differences were registered in the salivary cortisol concentration, systolic and diastolic pressure, heart rate, body temperature and stimulated salivary flow for treated group with music therapy.
Music therapy has a positive effect in control of dental anxiety.
