[Abstract] Ergometer training in stroke rehabilitation: systematic review and meta-analysis

Abstract

Objective

Ergometer training is routinely used in stroke rehabilitation. How robust is the evidence of its effects?

Data source

The PubMed database and PEDro database were reviewed prior to 22/01/2019.

Study selection

Randomized controlled trials investigating the effects of ergometer training on stroke recovery were selected.

Data extraction

Two reviewers independently selected the studies, performed independent data extraction, and assessed the risk of bias.

Data synthesis

A total of 28 studies (including 1115 stroke subjects) were included. The data indicates that

(1) ergometer training leads to a significant improvement of walking ability, cardiorespiratory fitness, motor function and muscular force of lower limbs, balance and postural control, spasticity, cognitive abilities, as well as the brain’s resistance to damage and degeneration,

(2) neuromuscular functional electrical stimulation assisted ergometer training is more efficient than ergometer training alone,

(3) high-intensity ergometer training is more efficient that low-intensity ergometer training, and

(4) ergometer training is more efficient than other therapies in supporting cardiorespiratory fitness, independence in activities of daily living, and balance and postural control, but less efficient in improving walking ability.

Conclusion

Ergometer training can support motor recovery after stroke. However, current data is insufficient for evidence-based rehabilitation. More data is required about the effects of ergometer training on cognitive abilities, emotional status, and quality of life in stroke subjects.

[WEB SITE] Accommodations Guide for Students with Brain Injury – Brainlinekids

The long-term effects of brain injury can be catastrophic for students at any level. Early on, students with the most severe injuries are unable to attend school. Some require home schooling until they recover enough to travel and attend classes with other students.Research shows that brain injury often harms basic cognitive abilities such as memory, learning, attention and concentration, word finding, and visual perception. Injury can also harm important academic abilities such as reading, arithmetic reasoning, vocabulary, writing, and spelling. Parents and students often worry about falling grades and failure. Concerns about passing the school year, graduating high school, or graduating from college with a degree are often expressed.Frequent complaints from students with brain injury include:

[REVIEW] Video games, cognitive exercises, and the enhancement of cognitive abilities – Full Text HTML

Highlights

• Cognitive training tools fall into two bins: video games and cognitive exercises.

• Factors such as fun, motivation, and adaptivity often differ across approaches.

• Expectancy and dose size can influence study effects during validation experiments.

• Hybrid tools leveraging the strengths of each approach may guide this field forward.

In this review we explore the emerging field of cognitive training via distinct types of interactive digital media: those designed primarily for entertainment (‘video games’) and those created for the purpose of cognitive enhancement (‘cognitive exercises’). Here we consider how specific design factors associated with each tool (e.g., fun, motivation, adaptive mechanics) and the study itself (e.g., participant expectancy, dose effects) can influence cognitive enhancement effects. We finally describe how the development of hybrid interventions that capitalize on strengths of each type of interactive digital media are anticipated to emerge as this field matures.

 

There are a number of interventions that have demonstrated the potential to enhance cognitive abilities, ranging from the more traditional (e.g., nutrition, exercise) to the more technological (e.g., pharmaceuticals, genetic therapies, neurostimulation). One approach, although still controversial [1], that has been gaining momentum is the use of interactive digital media to augment cognition, typically referred to as cognitive training. Over the last decade, there has been a surge in the number of interactive software programs created with claims of their ability to improve fundamental aspects of cognition known as cognitive control (i.e., attention, working memory, and goal management (multi-tasking/task-switching)). Although there have been promising results, few studies have successfully demonstrated clear improvements on untrained cognitive tasks (what we refer to as cognitive enhancement, generalized benefits or transfer 2• and 3]), and often not even for abilities that are highly related to training itself (i.e., near transfer 3, 4, 5 and 6]). In this review we differentiate between two types of interactive digital media: those designed primarily for entertainment [7•] (‘video games’) and those created for the purpose of cognitive enhancement (‘cognitive exercises’). Exploring this dichotomy, we will consider how certain factors associated with each type of intervention and corresponding study designs may influence the potential for cognitive enhancement and for validating it experimentally.
