Validation of the two minute step test for diagnosis of the functional capacity of hypertensive elderly persons

Abstract

Objectives : To analyze the accuracy of the 2 minute step test in the diagnosis of the normal functional capacity (FC) of hypertensive elderly individuals or hypertensive elderly individuals with other associated chronic conditions (ACC). Methods : An observational diagnosis type study of 101 subjects, 41 of whom were hypertensive and 60 of whom were normotensive, was carried out. Receiver Operating Characteristic curves (ROC) were constructed based on the normal FC variable. Results : For hypertensive patients, the 2MST, with an under the ROC curve area of 0.7 (95% CI: 0.50 to 0.87, p = 0.04), proved to be accurate at diagnosing FC. Among hypertensive individuals with an elevation of 69, sensitivity of 80% and specificity of 54% were observed. The 2MST was accurate at predicting normal FC among hypertensive patients with ACC, with an under the ROC curve area of 0.88 (95% CI: 0.69 to 1.00, p= 0.02). With an elevation of 65 the sensitivity was 83% and the specificity was 67%. Conclusions : The 2MST revealed good sensitivity and specificity when assessing the FC of elderly hypertensive individuals and elderly hypertensive patients with ACC, which was not the case among normotensive elderly persons.

Relationship between obstructive sleep apnea syndrome and functional capacity in patients with diabetes mellitus type 2: an observational transversal study

“…For this study, the number of right knee elevations for 2 min without running was counted and standardized. The minimum knee height, appropriate for the stride, was leveled at a midpoint between the patella and the anterosuperior iliac spine 11 .…”

“…Functional capacity may be negatively affected in individuals with OSA associated with fatigue, excessive sleepiness, excess weight, and low energy, which characterize the clinical presentation of the pathology 9 . Therefore, the 2-minute step test (2MST) appears as an alternative way to assess the functional capacity of an individual, considering that the ability to walk reflects the ability to maintain a series of activities of daily living in addition to enabling knowledge of the functional profile and the ability to guide decision-making in strategies aimed at preventing disabilities 10,11 .…”

Reproducibility and Validity of the 6-Minute Stationary Walk Test Associated With Virtual Reality in Subjects With COPD

“…6,7 It was observed that the test was valid and had good sensitivity and specificity to evaluate the functional capacity of hypertension in the elderly, with and without associated chronic conditions. 8 Therefore, our research group proposed a 6-min stationary walk test associated with virtual reality (STVR-6). 9 Virtual reality integrates the user with a synthetic 3-dimensional environment, 10 creating an immersive and interactive virtual experience that occurs in real time.…”
