	Tension headache - Wikipedia, the free encyclopedia
		Tension headaches, which were recently renamed tension-type headaches by the International Headache Society, are the most common type of headaches.
		Although muscle tension may be involved, there are many forms of tension headaches and some scientists now believe there is not one single cause for this type of headache.
		Tension headaches are exacerbated by states or activities that induce muscle tension, such as stress.

	Tension headache-Muscle contraction headache (Site not responding. Last check: 2007-10-25)
		Muscle Contraction Headache or Acute Tension Type Headache occurs in about 50% of the population on a monthly basis but is usually low impact which is why it is not seen a lot in primary care.
		The causes of tension headache are not known.
		The tension headache material is in no way intended to replace professional medical care or attention by your qualified medical practitioner.

	The Voice & Swallowing Center
		Muscle Tension Dysphonia is a voice disorder characterized by strained, effortful phonation usually causing vocal fatigue if used extensively.
		Primary muscle tension dysphonia - a type of vocalizing or speaking in which the muscles in the neck are tense and when no other lesion or paralysis is seen.
		Secondary muscle tension dysphonia - a compensatory method of vocalizing due either to a paralysis, paresis or muscular weakness causing the person to squeeze other parts of the larynx to help produce sound.

	Muscle Tension
		The hypothesis of overload of certain motor units is supported by the observation of an increased number of "ragged red" Type I muscle fibres in the trapezius muscle of workers exposed to monotonous shoulder load (Larsson et al., 1988; Bengtsson and Henriksson, 1989; Lindman et al., 1991; Larsson et al., 1992).
		The influence of the greater mental and physical demands on muscle tension may be related to the higher prevalence of musculoskeletal disorders among blue collar workers.
		Muscle pain associated to psychological factors in the workplace could be explained by a blocking of pauses in muscle activity unrelated to the actual biomechanical work being performed (Elert et al., 1992).

	Computer Study Links Mouse Position To Muscle Tension
		Chairs, keyboards and screens are often at the wrong height or angle, and the muscle tension that results can lead to long-term injuries and chronic pain that is difficult to remedy, according to studies by other researchers.
		Peper suggests that computer users can reduce muscle tension by switching to keyboards with a centrally located trackball or trackpad pointer instead of a mouse, or keyboards compact enough to allow the mouse to be used without extending the arm too much.
		Although he found reduced muscle tension among users of trackball or trackpad pointing devices, Peper noted that there is a low base level of tension any time a computer user approaches the keyboard.

	Chronic Tension Headache (Site not responding. Last check: 2007-10-25)
		Tension headache is generally described as a bilateral dull ache, pressure or cap-like pain that is usually located in the forehead, neck and shoulder regions.
		A study by Holroyd and his colleagues(10), detected no significant difference between subjects who trained to increase or decrease their muscle tension levels; high success feedback groups showed substantially greater improvements in headache activity (53%) than low success groups (26%).
		In this way, maintained muscle tension is minimized, while appropriate low levels of muscle activity is reinforced.

	Vocal hyperfunction & Muscle Tension Dysphonia
		To me, muscle tension dysphonia is characterized by the vocal folds typically failing to come completely together because two muscles are pulling in opposite directions simultaneously.
		If this lack of tension is from the thyroarytenoid muscle (the muscle inside the vocal cord itself) weakness, stroboscopy or high speed photography may best delinate the problem.
		This muscle is supplied by the superior laryngeal nerve, a different nerve from the one supplying the rest of the vocal box muscles.

		Therefore, it is important to get at the source of the tension and take preventative steps for eliminating the stress and helping the muscles return to their normal state of relaxation.
		However, the multifidous muscle which attaches to the lumbar vertebrae may not allow the separation of the vertebrae if the muscle is in too much spasm.
		When the muscles are in too much spasm to allow for this type of traction, upright types of traction units can enable a person to move their body during the therapy to avoid further muscle spasm, while providing a relieving therapy to the spine.

	Mouse Use Hikes Muscle Tension
		NEW YORK, Oct 13 (Reuters) -- People who use a mouse positioned to the side of their computer keyboard have greater muscle tension in the upper shoulder, back, and arm than those who use a centrally located trackball pointer, according to a new study in the October issue of the journal Ergonomics.
		Participants were told their performance was not being recorded, just their sensation of muscle tension.
		The researchers state that people who are unaware of muscle tension while using keyboards may be at greatest risk for developing musculoskeletal disorders in their shoulders, arms, wrists, and hands.

	Pelvic Floor Muscle Tension (Site not responding. Last check: 2007-10-25)
		The excessive tension may be a learned reaction to stress or pain or, it may occur with trauma to the pelvic structures, which leads to subtle, unrecognized injury to the nerves or muscles, which contribute to the development of "spasm" like activity in the muscles.
		An important distinction was made between the voluntary control characteristic of pelvic floor muscle, in contrast to the involuntary nature of the muscle of the rectum, colon and bladder.
		When we evacuate, we relax these muscles quickly and completely which cues the smooth muscle of the colon, rectum and bladder to propel feces or urine through the anal or urethral sphincters (the voluntary muscle which surrounds the urethra or anal canal).

	Speed and muscle tension (Site not responding. Last check: 2007-10-25)
		I was watching Barbara Lister Sink video and she made clear that the only obstacle to speed is accumulation of muscle tension as the piece proceeds and therefore the way to achieve speed is to play without accumulating any muscle tension.
		Tension in muscles that do not extend to the surface is not, or not as easily, detectable.
		Tension occurs at slow speed as well, but there is much more time for the muscles to relax, so that tension may not build up or reach unhealthy levels.

	Progressive Muscle Relaxation
		After tension, a muscle will be more relaxed than prior to the tensing.
		In time, you will recognize tension in any specific muscle and be able to reduce that tension.
		These exercises will not eliminate tension, but when it arises, you will know it immediately, and you will be able to "tense-relax" it away or even simply wish it away.

	Relaxation / Stress: Self-administered Progressive Muscle Relaxation (PMR)
		First you deliberately apply tension to certain muscle groups, and then you stop the tension and turn your attention to noticing how the muscles relax as the tension flows away.
		The process of applying tension to a muscle is essentially the same regardless of which muscle group you are using.
		Beginners usually make the mistake of allowing muscles other than the intended group to tense as well; in the example, this would be tensing muscles in your right arm and shoulder, not just in your right hand.

	Muscle Tension-Velocity
		Years before the protein constituents of muscle were known, experiments were done on the mechanical properties of isolated whole muscle.
		A muscle is stretched to a constant length while stimulated to tetanus, then it is released against a variable load.
		The next day the muscle forced to negative velocities will be sore, a side effect of the micro-injuries and the process of developing more muscle.

		The muscles that move your forearm to the C to the right are on the inside of the arm, the muscles that move your arm to the left are on the outside of the arm.
		When moving your arm to the left the opposite occurs: the muscles on the inside of the arm must relax as the muscles on the outside contract.

	muscle tension - velocity
		To increase tension (or velocity of contraction) muscle fibers are recruited, from the weakest cells with the most endurance up to the strongest fibers, which are most easily fatigued.
		Note that when an active muscle is pulled by an external load in the opposite direction of its intended contraction the muscle is "doing a negative" (as weightlifters say) and its velocity is less than zero.
		The tension per fiber is much greater in muscle fibers doing negatives than tension in a fiber going the same speed in the opposite (positive) direction.

		A controlled study of headache patients with muscle spasm in the neck and shoulders found that adding TENS to physical therapy (consisting of heat packs, massage, and ultrasound) brought a significantly faster and greater decline in headaches than physical therapy alone.
		A large controlled study of tension headache patients compared relaxation therapies (including progressive muscle relaxation, hypnosis, and cognitive psychotherapy) with EMG-biofeedback, and found biofeedback to be significantly more effective than relaxation in decreasing headache pain and frequency.
		Placebo-controlled evaluation of abbreviated progressive muscle relaxation and of relaxation combined with cognitive therapy in the treatment of tension headache.
