A laser device includes a light source that radiates a laser beam having one or more frequencies, and a nonlinear optical medium on which the laser beam is incident, the non-linear optical medium including at least one dispersive medium that is transparent and arranged along a direction in which the laser beam is radiated. The nonlinear optical medium drives a nonlinear optical process including generation of laser beams having different frequencies. The at least one dispersive medium has an effective thickness that causes a relative phase relationship among all the laser beams relevant to the nonlinear optical process to approximately satisfy a predetermined value.

Provided is an electrical stimulation device including a first to fourth electrodes, and an electrical stimulation generation section which supplies an electrical stimulation signal to each of the first to fourth electrodes. The electrical stimulation generation section supplies, to the first and second electrodes, an electrical stimulation signal according to a first stimulation pattern, and supplies, to the third and fourth electrodes, an electrical stimulation signal according to a second stimulation pattern. The first stimulation pattern is set so that an electrical stimulation signal for changing stimulation intensity according to a first waveform is supplied to the first electrode, and an electrical stimulation signal for changing stimulation intensity according to a second waveform is supplied to the second electrode, the second waveform being increased and decreased in conjunction with the first waveform. The second stimulation pattern is set so that an electrical stimulation signal for changing stimulation intensity according to a third waveform is supplied to the third electrode, and an electrical stimulation signal for changing stimulation intensity according to a fourth waveform is supplied to the fourth electrode, the fourth waveform being increased and decreased in conjunction with the third waveform. The electrical stimulation generation section alternately performs electrical stimulation of the first stimulation pattern and electrical stimulation of the second stimulation pattern.

Minneapolis, May 5, 2016 -- Simple calf muscle stretching may reduce leg pain when walking and increase blood flow for people living with peripheral artery disease, according to a preliminary abstract presented at the American Heart Association's Arteriosclerosis, Thrombosis and Vascular Biology | Peripheral Vascular Disease 2017 Scientific Sessions. "This is a very safe, easy intervention that can be done at home and has the potential to really improve your tolerance for walking and get you into a walking program," said Judy M. Muller-Delp, Ph.D., senior study author and professor of biomedical sciences at the Florida State University College of Medicine in Tallahassee. Peripheral artery disease (PAD) affects more than 8.5 million American adults and many are unaware they have it. The most common symptom in the lower extremities is a painful muscle cramping in the hips, thighs or calves when walking, climbing stairs or exercising. The pain of PAD often goes away when you stop exercising, although this may take a few minutes. If there's a blood-flow blockage due to plaque buildup, the muscles won't get enough blood during exercise to meet the needs. The "crampy" pain (called intermittent claudication), when caused by PAD, is the muscles' way of warning the body that it isn't receiving enough blood during exercise to meet the increased demand. In the current study, researchers evaluated 13 patients (six women and seven men; average age 71), most taking a statin drug and anti-platelet medications. Participants were instructed to passively stretch their calf muscle in 30-minute daily sessions using a splint that flexed the ankle about 15 percent. Walking ability and blood flow were measured after 4 weeks of calf stretching of each leg (5 days a week) and after 4 weeks without the special stretches. Compared to a month of not stretching, after one month of daily calf stretches the participants: Structured walking programs are a cornerstone of PAD treatment, along with medication and sometimes interventions to open clogged blood vessels. "A physical therapist can instruct you how to adjust and wear the splints correctly so you can do the stretches at home. There is no doubt about the benefit of exercise training on blood vessel health in PAD patients. If you have limited walking ability, I recommend that you at least perform muscle stretches so you can gain enough comfort and confidence in walking to participate in a walking exercise program," said Kazuki Hotta, Ph.D., lead author of the study and a postdoctoral fellow in engineering science at the University of Electro-Communications in Tokyo. According to the American Heart Association's 2017 Statistical Update, about 10 percent of people with PAD have the classic crampy pain symptom of intermittent claudication. Approximately 40 percent do not complain of leg pain, whereas the remaining 50 percent have a variety of different leg symptoms. Other co-authors are Wayne B.

An orthosis 1 includes: an outer layer 2 which maintains a substantially elliptic shape; and a buffer 3 provided on the inner periphery of the outer layer 2, and buffers predetermined sites on the head. When the orthosis 1 is worn deviating from a state where the minor axis of the substantially elliptic shape corresponds to the width of the head, pressers 24a, 24b are formed which press the predetermined sites on the head with a stronger force than a force before deviation. The outer layer 2 includes adjustment portions 23a and 23b which can be close or apart in the minor axis direction of the substantially elliptic shape. The orthosis 1 further includes an adjuster 4 which adjusts the adjustment portions 23a, 23b so that the length of the minor axis of the substantially elliptic shape can correspond to the width of the head.
