Objective: To assess the impact of cognitive Dual Task (DT) during walking on the energy cost of walking (Cw) in individuals with subacute stroke. The secondary objective was to determine whether there is an association between the Cw and cortical activity of the prefrontal area.
Methods: Any individual with stroke localized in the temporal-parietal regions and able to walk without human assistance was included.
Article Synopsis
- * Involving 56 healthy participants, the study found no significant correlation between perceived exertion and actual energy expenditure for either age group during a session that included computer work, treadmill walking, biking, and running.
- * Older adults reported feeling more exerted than younger individuals during computer work, walking, and running, suggesting that combining perceived exertion with other methods might better assess exercise intensity in older populations.
Article Synopsis
- Increased energy costs of walking (Cw) in stroke patients are linked to their walking ability and independence, but the effect on their quality of life (QoL) has not been previously explored.
- A study with 37 stroke patients found that higher Cw significantly impacted QoL assessments taken after hospital discharge, particularly at six months and one year later.
- The findings suggest that both Cw and mood disorders (measured by HADS) are important predictors of QoL, emphasizing the need for early interventions to improve these factors for better long-term outcomes.
Article Synopsis
- Eighty-four stroke patients were split into two groups: one received the coaching program and the other did not, with evaluations conducted at the beginning and the end of the study.
- While walking distance improved significantly in the experimental group, there were no changes in heart rate variability for either group, suggesting the need for further research on recovery timing and exercise intensity's effects.
Objective: To evaluate the validity and test-retest reliability of physical activity trackers (accelerometer, multisensor, smartphone, pedometer) for estimating energy expenditure during walking in individuals with stroke.
Data Sources: Webline, MEDLINE, Scopus, ScienceDirect, Bielefeld Academic Search Engine, and Wiley Online Library databases from 1980 to November 2020.
Study Selection: The inclusion criteria were studies that examined the validity of portable physical activity trackers for estimating energy expenditure in individuals with stroke during walking activities compared to indirect calorimetry.
Background: The integration of oxygen cost into the accelerometer's algorithms improves accuracy of total energy expenditure (TEE) values as post-stroke individuals walk. Recent work has shown that oxygen cost can be estimated from specific prediction equations for stroke patients.
Objective: The objective is to the validity of the different oxygen cost estimation equations available in the literature for calculating TEE using ActigraphGT3x as individuals with stroke sequelae walk.
Article Synopsis
- - The study investigates how accurately the oxygen cost of walking (Cw) can be estimated using different walking speed measurement methods in stroke patients who can walk independently.
- - Twenty-one stroke survivors participated, and Cw estimates from various tests were compared with direct measurements from a gas analyzer, showing no significant differences between them.
- - The results suggest that using a 10-m walking test, 6-minute walking test, or GaitRite system is reliable for estimating Cw, as indicated by a high level of agreement and consistency in measurements.
Objective: To evaluate the association between self-selected walking speed (S), oxygen consumption at S (Vo), the oxygen cost of walking (Cw) at S, and mobility independence and independence for activities of daily living in individuals poststroke.
Design: Cross-sectional study.
Setting: Hospital.
Stroke patients often exhibit difficulties performing a cognitive task while walking, defined as a dual task (DT). Their prefrontal cortex (PFC) activity is higher in DT than in single task (ST). The effects of an increasing load on PFC activity during DT in subacute stroke patients remains unexplored.

The energy expenditure estimated using the SenseWear Armband was compared to the energy expenditure calculated from oxygen consumption, measured by a portable indirect calorimeter (Metamax 3B).

Methods: Post-stroke patients able to walk without human assistance were equipped with several wearable devices: pedometers, Actigraph, and Sensewear Armband placed according to the manufacturers' recommendations.
Objective: The aim of the study was to measure the metabolic equivalent task when performing physical activities of daily living in poststroke individuals.
Design: Poststroke individuals who were able to walk without human assistance were recruited and asked to perform the following activities of daily living: washing dishes (activity code: 05041 in Ainsworth's compendium), walking at a slow pace of less than 2 mph (activity code: 17151), climbing stairs (activity code: 17133), and walking down stairs (activity code: 17070). The metabolic equivalent task was measured along these activities using a portable breath gas exchange analyzer.
Objective:: To explore the validity of the Actigraph and the influence of the placement of the sensor when estimating the active energy expenditure in four common daily activities (transfers, manual task, walking in overground and walking up and down stairs) in stroke survivors.
Design:: Cross-sectional study.
Setting:: Department of Physical Medicine and Rehabilitation.
Background The Borg Scale for the rating of perceived exertion (RPE) is recommended to measure the intensity of physical exercise during stroke rehabilitation, but its reliability in activities of daily living is not explored. Objective To evaluate the correlation between the RPE using the Borg Scale (6-20) and the intensity of effort as measured by the Total Energy Expenditure per minute (TEE.min) in a post-stroke population for two tasks: walking at spontaneous comfortable speed and walking up and down stairs.

This study focused on the effects of training on the morphological and functional characteristics of the left ventricle. This study investigated the effects of training on LV function using Speckle Tracking Imaging (STI) in high-level, young rugby players.
