Background. A biofeedback program receives attention as an intervention program for athletes to regulate their psychological state. Objectives. The purpose was to apply for a heart rate variability (HRV) biofeedback training program and validate its effectiveness for racket sports players. Methods. The participants were eight elite sport athletes (three men and five women): five squash players...

conclusion the results of the study suggest that biofeedback training may help to train stressed athletes to acquire a control over their psychophysiological processes, thus helping an athlete to perform maximally. results two way repeated measure anova was used to simultaneously compare within and between group differences. response time, concentration, heart rate variability, respiration rate...

Bibliographic searches identified 14 controlled and uncontrolled outcome evaluations of biofeedback-based treatments for temporomandibular disorders published since 1978. This literature includes two randomized controlled trials (RCTs) of each of three types of biofeedback treatment: (1) surface electromyographic (SEMG) training of the masticatory muscles, (2) SEMG training combined with adjunc...

EFFECT OF BIOFEEDBACK DEVICES IN PARTIAL WEIGHT-BEARING ORTHOPAEDIC PATIENTS. Joshua W Hustedt, Michael R Baumgaertner, Michael P Leslie, Jonathan N Grauer. Department of Orthopaedics and Rehabilitation, Yale University School of Medicine, New Haven, CT. Partial weight-bearing (PWB) instructions are commonly given to orthopaedic patients. However, the ability of patients to comply with these in...

The aim of this study was to examine the effect of resonant breathing biofeedback training for reducing stress among manufacturing operators. Resonant breathing biofeedback works by teaching people to recognize their involuntary heart rate variability and to control patterns of this physiological response. Thirty-six female operators from an electronic manufacturing factory were randomly assign...

Clinical applications of biofeedback have proliferated and considerable lore surrounding the application of these techniques has evolved. Many assertions about the effectiveness of biofeedback training are based on findings of the least well-controlled studies, while many of the better controlled studies have failed to show that biofeedback directly mediates target symptoms or is superior to ot...

Orthopedic patients are often instructed on how much weight to bear on an injured or postoperative extremity. Although specific weight-bearing instructions are given to a majority of lower-extremity orthopedic patients, the ability of patients to comply with these instructions is questioned in the medical literature. This study compared the effectiveness of new forms of clinical interventions d...

This study describes a new simulator that provides haptic biofeedback to help manual wheelchair users gain a more effective propulsion pattern. Propulsion effectiveness is measured using the mechanical effective force (MEF). The simulator implements a dynamic model that replicates overground propulsion conditions. Haptic biofeedback increases the feeling of rolling resistance if the user’s MEF ...
