A real-time feedback method to reduce loading rate during running: Effect of combining direct and indirect feedback

ABSTRACT Impact loading plays a key role in the pathophysiology of running-related injuries. Providing real-time feedback may be an effective strategy to reduce impact loading; however, it is currently unclear what an effective training method to help runners achieve a habitual low loading rate is. We subjected 20 healthy non-runners to a structured sequence of direct and indirect biofeedback designed to facilitate broader exploration of neuro-mechanical workspace for potential movement solutions (indirect feedback on cadence and foot-strike angle) and to refine and converge upon an optimal sub-set of that space to match the task goal (direct feedback on loading rate). While indirect biofeedback on foot-strike angle yielded a lower impact load than providing direct biofeedback on loading rate, compared to indirect biofeedback on foot-strike angle, providing direct feedback on loading rate statistically increased (+58%, p = 0.007) the range of goal-relevant solutions participants used to lower their impact loading. Results showed that structured feedback was effective in increasing the range of input parameters that match the task goal, hence expanding the size of goal-relevant solutions, which may benefit running performance under changing environmental constraints.

OS EFEITOS DO SOFTWARE CARDIOEMOTION® NA COERÊNCIA CARDÍACA: REVISÃO BIBLIOGRÁFICA

Studies demonstrate the positive effects of biofeedback on subjects with asthma, coronary heart disease, heart, hypertension, reduction of cortisol and dehydroepiandrosterone increase in cardiovascular exercise with biofeedback software by using CardioEmotion. This study has the general objective to review literature on cardiovascular and cardiac coherence biofeedback in order to demonstrate the broad range of applications and results in various physical and psycho-emotional states. The site of research that has the greatest number of keywords in evidence is the SCIENCE DIRECT. So we realize that the Cardioemotion® shows from 2000 to 2015, increasing indicators of interest to notice that the direct descriptors are in more articles in PUBMED, Cardioemotion ® (5,663) and Cardiac Coherence (12) in SCIENCE DIRECT; indirect Biofeedback (10,778) and physiotherapy (4405) both in SCIENCE DIRECT. The analysis of the total data clearly shows for the period 200-2015 significant quantitative increase in all key search word confirming an increasingly frequent presence in the literature of the Health Sciences.

Biofeedback and Virtual Environments

This paper explains potential benefits of indirect biofeedback used within interactive virtual environments, and reflects on an earlier study that allowed for the dynamic modification of a virtual environment's graphic shaders, music and artificial intelligence, based on the biofeedback of the player. The aim was to determine which augmented effects aided or discouraged engagement in the game. Conversely, biofeedback can help calm down rather than stress participants, and attune them to different ways of interacting within a virtual environment. Other advantages of indirect biofeedback might include increased personalization, thematic object creation, atmospheric augmentation, filtering of information, and tracking of participants' understanding and engagement. Such features may help designers create more intuitive virtual environments with more thematically appropriate interaction while reducing cognitive loading on the participants. Another benefit would be more engaged clients with a better understanding of the richness and complexity of a digital environment.

Relearning to swallow after stroke—application of maneuvers and indirect biofeedback

A patient with medullary infarct recovered swallowing at 45 months after stroke by using a series of pharyngeal swallow maneuvers. Each maneuver effected quantifiable changes in specific elements of the pharyngeal swallow. The success of these maneuvers is the basis for the conceptualization of the pharyngeal swallow as a cluster of closely coordinated neuromuscular actions which are independently modifiable, rather than a single event.

Reduction of blood pressure by indirect biofeedback

Forty-five randomly assigned subjects served in either a relaxation control, an EMG plus thermal, or a thermal biofeedback group. All groups received the same relaxation manipulation. Experimental results demonstrated a significant drop in both diastolic and systolic blood pressure for the feedback treatment. Diastolic measures showed a somewhat greater decrease for the EMG plus thermal treatment condition. A learning effect was demonstrated both within and across the three experimental sessions. Given that the sample was normotensive, the 20% reduction in blood pressure was notable. The results support the idea that blood pressure biofeedback is not a necessary condition for reduction of arterial blood pressure.
