Chair rise and Step ups Exercises

aerobic exercise i.e. low intensity walking

Progressive lower limb activities (Chair rise and Step ups) were be carried out weekly for upto 6 weeks. Before initiation, cardiopulmonary parameters i.e. Heart rate, oxygen saturation, cardiac output and stroke volume were measured at baseline and later at the termination of activity on each week. Initially, five repeated chair rise were conducted through SPPB and the time was noted to complete the task and step ups through 6MWD for a total period of 30 min. Lastly, fatigue component was assessed via FAS.

Changes from the baseline ; It is a 21 item paper self administered questionnaire. It aims to measure the extent to which HF prevents patients from living the way they would want to. The MLHFQ has been the most widely used instrument for evaluating HRQL in HF patients internationally. Five years ago, the MLHFQ was identified as the questionnaire with the best properties and even now it has the highest scores for reliability, and a good ability to both measure its objective (validity) and detect change over time

Changes from the baseline ; The SPPB is composed of 3 components-standing balance, gait, speed, and timed repeated chair rise-each scored on a scale from 0 to 4 and combined for a total score of 0 to 12. This protocol consisted of 3 types of progressive activities. Each type contains 2 to 4 tasks, performed in a single attempt. The protocol was performed in 30-minute sessions once a week. It was used to conduct chair rise activity only. Participant was asked to complete five chair stands and the time was noted and scored from 0-4 respectively.

Changes from the baseline ; The 6 min walk test (6MWT) is a functional performance measure to examine the functional status of patients with heart and lung disease. This protocol has 1 item only. It was completed in less than 10 minutes. A 6MWT distance of 300 m was also recently found to be a significant predictor of all-cause mortality in a multivariate model examining predictors of clinical outcome in elderly patients with advanced HF. Patients were instructed to cover the greatest distance possible during the allotted time, at a self-determined walking speed, and were allowed to pause and rest when needed. The distance covered was measured by a body-borne pedometer with which the total number of steps taken during the 6MWT were used to calculate the 6MWT distance using the equation reported by Roul et al. (d ¼ y × 10 m/x; where d ¼ distance ambulated in m; y ¼ total number of steps during 6MWT; and x ¼ number of steps for each subject to cover 10 m
