This study investigated a simple biofeedback-assisted training protocol for increasing somatic awareness as well as reducing dyponesis. Twelve normal, healthy volunteers with no known musculoskeletal impairments (mean age of 23.8 years) were trained to increase awareness of “wasted effort” in the neck muscles during a simple bending task. Surface electromyography (sEMG) signals were recorded from the midcervical paraspinal muscles (C-5) while the subject performed a forward fold, also described as a “toe touch” movement. The quantitative measures of sEMG activity were compared to a subjective measure of neck muscle tension. During the pretraining measurements, 11 of 12 participants reported no subjective awareness of increased neck muscle tension while bending in a forward fold “toe touch” position. After approximately 10 minutes of “dysponesis awareness training,” all participants had measurable reductions in neck muscle tension, as well as reductions in the subjective sense of tension while performing the forward fold exercise, as compared to pretraining. The 11 participants who increased their self-awareness following training reported not only feeling decreased neck muscle tension but also increased general relaxation levels. The findings suggest that most individuals may be unaware of increased muscle tension during simple activities such as a forward bend, yet may rapidly learn how to reduce dysponesis, such as unnecessary neck muscle overexertion during a forward bend. Furthermore, sEMG dysponesis awareness training could be adapted to rapidly train individuals such as athletes to reduce unnecessary muscle use.

INTRODUCTION: We compared the physiological responses, psychomotor performances, and hypoxia symptoms between 7000 m and 7500 m (23,000 and 24,600 ft) exposure to develop a safer hypoxia training protocol.METHODS: In altitude chamber, 66 male pilots were exposed to 7000 and 7500 m. Heart rate and arterial oxygen saturation were continuously monitored. Psychomotor performance was assessed using the computational task. The hypoxic symptoms were investigated by a questionnaire.RESULTS: The mean duration time of hypoxia was 323.0 56.5 s at 7000 m and 218.2 63.3 s at 7500 m. The 6-min hypoxia training was completed by 57.6% of the pilots and 6.1% of the pilots at 7000 m and at 7500 m, respectively. There were no significant differences in pilots heart rates and psychomotor performance between the two exposures. The Spo2 response at 7500 m was slightly severer than that at 7000 m. During the 7000 m exposure, pilots experienced almost the same symptoms and similar frequency order as those during the 7500 m exposure.CONCLUSIONS: There were concordant symptoms, psychomotor performance, and very similar physiological responses between 7000 m and 7500 m during hypoxia training. The results indicated that 7000-m hypoxia awareness training might be an alternative to 7500-m hypoxia training with lower DCS risk and longer experience time.Wen D, Tu L, Wang G, Gu Z, Shi W, Liu X.

In this paper, a new electromyographic phenomenon, referred to as Bursting Rate Variability (BRV), is reported. Not only does it manifest itself visually as a train of short periods of accrued surface electromyographic (sEMG) activity in the traces, but it has a deeper underpinning because the sEMG bursts are synchronous with wavelet packets in the D8 subband of the Daubechies 3 (db3) wavelet decomposition of the raw signal referred to as “D8 doublets”—which are absent during muscle relaxation. Moreover, the db3 wavelet decomposition reconstructs the entire sEMG bursts with two contiguous relatively high detail coefficients at level 8, suggesting a high incidence of two consecutive neuronal discharges. Most importantly, the timing between successive bursts shows some variability, hence the BRV acronym. Contrary to Heart Rate Variability (HRV), where the R-wave is easily identified, here, time-localization of the burst requires a statistical waveform matching between the “D8 doublet” and the burst in the raw sEMG signal. Furthermore, statistical fitting of the empirical distribution of return times shows a striking difference between control and quadriplegic subjects. Finally, the BRV rate appears to be within 60–88 bursts per minute on average among 9 human subjects, suggesting a possible connection between BRV and HRV.

The principles of R-S learning were applied to a 32-yr.-old Caucasian woman to reduce the frequency and duration of fingernail-biting activity in a reversal-replication (ABAB) research design. The undesirable behavior, fingernail-biting which included frequency and duration, antecedents, and setting events, was recorded during a 28-day study. Self-monitoring recordings indicated that anxiety was the most prevalent antecedent. Through the use of a preliminary questionnaire and interview, increase in self-awareness was judged to be most effective in the extinction of the un-desired behavior. The systematic desensitization techniques of deep muscle relaxation and Transcendental Meditation were used during the treatment phase.

The goal of the experiment was to assess the physical stress experienced by an operator during the use of harvester equipment. Experimental data was obtained from field measurements with a Biofeedback 2000<sup>x-pert</sup> (BFB) unit, which allows recording of selected physiological parameters on the operator, especially an electromyogram of target muscle groups, body temperature, breathing rate and pulse. Experimental data was interpreted by comparing it with values measured during normal human activities. Measurements were done during logging using a harvester, a chainsaw, while skidding with a horse, while running, and while walking normally. The results of the experiment showed that the electromyograph (EMG) of the investigated muscle groups exhibited values 164% higher during running than during the cut-to-length (CTL) production, up to 77% higher while walking, up to 28% higher during logging with a chainsaw, and even up to 230% higher values while skidding with a horse. Body temperature and pulse measurements did not show a significant difference in values measured during CTL production and during other activities. &nbsp; &nbsp;

Abstract Background Chronic neck pain is frequently found in office workers affecting quality of life; also, stress is one participating factor. Though stretching incorporating deep-slow breathing (DSB) has benefits on health, an effective and suitable technique for office workers to perform in the workplace is a gap in need of fulfilment. Methods We explored the effective pattern of stretching with DSB to reduce neck tension and promote relaxation within the shortest time. Thirty-two female participants with neck tension were allocated into two steps totaling five patterns (n=8 for each pattern). Firstly, they performed two patterns; two other patterns were developed and compared with DSB alone. Muscle tension, pain score, and heart rate variability (HRV) were immediately measured. Results All patterns performed with the eyes closed decreased muscle tension more than those performed with the eyes open; the pain amid all stretching groups subsequently decreased. Only a bout of slow stretching, performed synchronously with the eyes closed along with a period of deep inhalation increased the parasympathetic activity of HRV; an increase in pain was reported after stretching. Conclusions A slowed and synchronized pattern between stretching with DSB and eyes closed period, performed at least four times repeatedly rendered benefits in reducing neck pain and tension, in addition to promoting relaxation within a short period; however, the DSB pattern and the feeling of the stretched muscle to promote relaxation were individual differences. Thus, future studies should come up with apposite training methods adjusted to fit individuals; self-awareness toward these aspects ought to be encouraged.

Tension in the muscles of the neck has been found to be a major contributing factor to pain and discomfort among office workers. It was the purpose of this study to produce a mathematical model for the prediction of neck muscle tension based on source document placement at a word processing workstation. 20 subjects were electromyographically sampled for levels of neck muscle tension during both reading and typing tasks in six different source document positions. Measures of head position were also taken in each document position under each condition. From this data a series of regression equations was developed which predict neck muscle tension based on both document position and head position.
