Improving dynamic balance by self-controlled feedback in children with cerebral palsy
Human Movement Science, 2023Maintaining balance is an important topic for participation of children with Cerebral Palsy (CP) in their own activities. Purpose of the present study was to investigate the effect of self-controlled and yoked-group feedback on dynamic balance of children with Spastic Hemiplegic Cerebral Palsy (SHCP).Using Convenience Sampling Method, twenty students ...

Antenna module self-controlling gain with sensitivity feedback
IET Seminar on RF for DVB-H/DMB Mobile Broadcast: Handset and Infrastructure Challenges, 2006The prototype of antenna module for Japanese digital TV on handy phone was developed. Tuning antenna can cover wider system band with small size. Tuning antenna and direct connecting LNA improve NF of antenna module. Adaptive tuning control by using sensitivity signal from tuner module effectively compensate degradation by human body.

Neural mechanism underlying self-controlled feedback on motor skill learning
Human Movement Science, 2019The present study investigated the neural mechanisms of self-controlled (SC) feedback underlying its learning advantages. Forty-two participants, including 24 females (16.43 ± 2.61 years) and 18 males (17.56 ± 0.86 years), were randomly assigned to a SC or yoked (YK) group.

A Simple Feedback System for Self-Control of Blood Pressure
Perceptual and Motor Skills, 1974A relatively simple, open-loop, feedback system, based on closed-circuit television, which can be used to teach Ss to control their blood pressure is described, along with two experiments which demonstrate its efficacy. In the first experiment 10 normotensive Ss were able to increase systolic blood pressure with the aid of feedback over the level ...

Research Quarterly for Exercise and Sport, 2002
This paper examines whether self-controlled feedback schedules enhance learning, because they are more tailored to the performers' needs than externally controlled feedback schedules. Participants practiced a sequential timing task. One group of learners (self-control) was provided with feedback whenever they requested it, whereas another group (yoked)

Experimental control of chaos by delayed self-controlling feedback
Physics Letters A, 1993Abstract A recently proposed method [K. Pyragas, Phys. Lett. A 170 (1992) 421] of chaos control by a small time-continuous perturbation is realized experimentally. The required delayed feedback is achieved by a specially designed analogue circuit using a simple delay line. The experimental results are supplemented by computer simulation.

Self-control over combined video feedback and modeling facilitates motor learning
Human Movement Science, 2016Allowing learners to control the video presentation of knowledge of performance (KP) or an expert model during practice has been shown to facilitate motor learning (Aiken, Fairbrother, & Post, 2012; Wulf, Raupach, & Pfeiffer, 2005). Split-screen replay features now allow for the simultaneous presentation of these modes of instructional support.

Influence of Self-Controlled Feedback on Learning a Serial Motor Skill
Perceptual and Motor Skills, 2015Self-controlled feedback on a variety of tasks are well established as effective means of facilitating motor skill learning. This study assessed the effects of self-controlled feedback on the performance of a serial motor skill. The task was to learn the sequence of 18 movements that make up the Taekwondo Poomsae Taegeuk first, which is the first ...

Self Control of Stress‐Induced Cardiovascular Change Using Transit Time Feedback
Psychophysiology, 1982ABSTRACTForty‐eight normotensive subjects underwent one of four training conditions: Transit time plus stress (TTPS), Transit time minus stress (TTMS). False feedback plus stress (KF), and a stress only Control (C). In the first session, all subjects received an arithmetic stressor but without training.

Hypertension self-control with a portable feedback unit or meditation-relaxation
Biofeedback and Self-Regulation, 1978Thirty borderline essential hypertensives were randomly assigned to a portable constant-cuff blood pressure feedback technique or meditation-relaxation. Each technique was taught in the laboratory, then practiced twice daily at home for four weeks. Subjects mailed daily records of their progress.
