Prevention is better than cure... Therapists and physicians agree that you can help avoid carpal tunnel syndrome and impaired hand function by reducing the amount of wrist bend. While typing, to help avoid carpal tunnel syndrom keep your hands, wrists, and forearms straight. Hold your elbows close to your sides. Do not rest your wrists on the keyboard or the desk. Use a padded wrists rest to elevate your wrists and give them a place to rest. Use a Good mouse pad. Use a mouse wrist rest. The mouse wrist rest gives your wrists support as you use the mouse & Type softly.

Stretching is so easy... it costs nothing.~ Take the time and a little energy each day to invest towards a long lasting, flexible, Healthy muscles, tendons, ligaments and Body.
Stretching is the process of placing particular parts of the body in a position which will lengthen the tendons and muscles. It enhances athletic performance, reduces the possibilities of injury and minimise muscle soreness.
The benefits of Stretching is extended range of movement, this gives increased comfort, a greater ability to move more freely and reducing our risk of injury. Stretching makes you feel good about yourself motivating you to participate in exercise.

Key points to remember whilst stretching:
Rules for stretching are:
Main Types of stretching are:
|
Active stretchingActive stretching is one where you assume a position and then hold it there with no assistance other than using the strength of your agonist muscles, example, bringing your leg up high and then holding it there without anything (other than your leg muscles themselves) to keep the leg in that extended position. The tension of the agonists in an active stretch helps to relax the muscles being stretched (the antagonists) by reciprocal inhibition. Active stretching increases active flexibility and strengthens the agonistic muscles. Active stretches are usually quite difficult to hold and maintain for more than 10 seconds and rarely need to be held any longer than 15 seconds.
Passive stretching Passive stretching is also referred to as relaxed stretching, and as static-passive stretching. A passive stretch is one where you assume a position and hold it with some other part of your body, or with the assistance of a partner or some other apparatus. For example, bringing your leg up high and then holding it there with your hand. The splits is an example of a passive stretch (in this case the floor is the "apparatus" that you use to maintain your extended position). Passive stretching is a technique in which you are relaxed and make no contribution to the range of motion. Instead, an external force is created by an outside agent, either manually or mechanically. Notice that the definition of passive stretching given in the previous section encompasses both of the above definitions. Throughout this document, when the term static stretching or passive stretching is used, its intended meaning is the definition of passive stretching as described in the previous section. You should be aware of these alternative meanings, however, when looking at other references on stretching. Slow, relaxed stretching is useful in relieving spasms in muscles that are healing after an injury. Obviously, you should check with your doctor first to see if it is okay to attempt to stretch the injured muscles. Relaxed stretching is also very good for "cooling down" after a workout and helps reduce post-workout muscle fatigue, and soreness.
Static StretchingMany people use the term "passive stretching" and "static stretching" interchangeably. However, there are a number of people who make a distinction between the two. According to M. Alter: Static stretching involves holding a position. That is, you stretch to the farthest point and hold the stretch ...
Isometric stretching Isometric stretching is a type of static stretching (meaning it does not use motion) which involves the resistance of muscle groups through isometric contractions (tensing) of the stretched muscles. The use of isometric stretching is one of the fastest ways to develop increased static-passive flexibility and is much more effective than either passive stretching or active stretching alone. Isometric stretches also help to develop strength in the "tensed" muscles (which helps to develop static-active flexibility), and seems to decrease the amount of pain usually associated with stretching. The most common ways to provide the needed resistance for an isometric stretch are to apply resistance manually to one's own limbs, to have a partner apply the resistance, or to use an apparatus such as a wall (or the floor) to provide resistance. An example of using a partner to provide resistance would be having a partner hold your leg up high (and keep it there) while you attempt to force your leg back down to the ground. An example of using the wall to provide resistance would be the well known "push-the-wall" calf-stretch where you are actively attempting to move the wall (even though you know you can't). Isometric stretching is not recommended for children and adolescents whose bones are still growing. These people are usually already flexible enough that the strong stretches produced by the isometric contraction have a much higher risk of damaging tendons and connective tissue.
The proper way to perform an isometric stretch is as follows: Tense the stretched muscle for 7-15 seconds (resisting against some force that will not move, like the floor or a partner). Finally, relax the muscle for at least 20 seconds.
How Isometric stretching works: When you isometrically contracted, some of the resting fibers would contract, many of the resting fibers would stretch, and many of the already stretched fibers, which are being prevented from contracting by the inverse myotatic reflex [the lengthening reaction], would stretch even more. When the isometric contraction was relaxed and the contracting fibers returned to their resting length, the stretched fibers would retain their ability to stretch beyond their normal limit. ... the whole muscle would be able to stretch beyond its initial maximum, and you would have increased flexibility ... The reason that the stretched fibers develop and retain the ability to stretch beyond their normal limit during an isometric stretch has to do with the muscle spindles: The signal which tells the muscle to contract voluntarily, also tells the muscle spindle's (intrafusal) muscle fibers to shorten, increasing sensitivity of the stretch reflex. This mechanism normally maintains the sensitivity of the muscle spindle as the muscle shortens during contraction. This allows the muscle spindles to habituate (become accustomed) to an even further-lengthened position. PNF stretching is currently the fastest and most effective way known to increase static-passive flexibility. PNF is an acronym for proprioceptive neuromuscular facilitation. It is not really a type of stretching but is a technique of combining passive stretching and isometric stretching in order to achieve maximum static flexibility. Actually, the term PNF stretching is itself a misnomer. PNF was initially developed as a method of rehabilitating stroke victims.
PNF refers to any of several post-isometric relaxation stretching techniques in which a muscle group is passively stretched, then contracts isometrically against resistance while in the stretched position, and then is passively stretched again through the resulting increased range of motion.
PNF stretching usually requires a partner to provide resistance against the isometric contraction and then later to passively take the joint through its increased range of motion. It may be performed, however, without a partner, although it is usually more effective with a partner's assistance. Most PNF stretching techniques employ isometric agonist contraction/relaxation where the stretched muscles are contracted isometrically and then relaxed. Some PNF techniques also employ isometric antagonist contraction where the antagonists of the stretched muscles are contracted. In all cases, it is important to note that the stretched muscle should be rested (and relaxed) for at least 20 seconds before performing another PNF technique.
The most common PNF stretching techniques are the hold-relax, also called the Contract-relax. After assuming an initial passive stretch, the muscle being stretched is isometrically contracted for 7-15 seconds, after which the muscle is briefly relaxed for 2-3 seconds, and then immediately subjected to a passive stretch which stretches the muscle even further than the initial passive stretch.
This final passive stretch is held for 10-15 seconds. The muscle is then relaxed for 20 seconds before performing another PNF technique.
This technique is also called the contract-relax-contract, and the contract-relax-antagonist-contract (or CRAC). It involves performing two isometric contractions: first of the agonists, then, of the antagonists. The first part is similar to the hold-relax where, after assuming an initial passive stretch, the stretched muscle is isometrically contracted for 7-15 seconds. Then the muscle is relaxed while its antagonist immediately performs an isometric contraction that is held for 7-15 seconds. The muscles are then relaxed for 20 seconds before performing another PNF technique. This technique (and a similar technique called the hold-relax-bounce) actually involves the use of dynamic or ballistic stretches in conjunction with static and isometric stretches. It is very risky, and is successfully used only by the most advanced of athletes and dancers that have managed to achieve a high level of control over their muscle stretch reflex. It is similar to the hold-relax technique except that a dynamic or ballistic stretch is employed in place of the final passive stretch. This PNF technique is considered one of the safest PNF techniques to perform (less likely to result in torn muscle tissue). Some people like to make the technique even more intense by adding the final passive stretch after the second isometric contraction. Although this can result in greater flexibility gains, it also increases the likelihood of injury. Even more risky are dynamic and ballistic PNF stretching techniques like the hold-relax-swing, and the hold-relax-bounce. If you are not a professional athlete or dancer, you probably have no business attempting either of these techniques (the likelihood of injury is just too great). Even professionals should not attempt these techniques without the guidance of a professional coach or training advisor. These two techniques have the greatest potential for rapid flexibility gains, but only when performed by people who have a sufficiently high level of control of the stretch reflex in the muscles that are being stretched. Like isometric stretching PNF stretching is also not recommended for children and people whose bones are still growing (for the same reasons. Also like isometric stretching, PNF stretching helps strengthen the muscles that are contracted and therefore is good for increasing active flexibility as well as passive flexibility. Furthermore, as with isometric stretching, PNF stretching is very strenuous and should be performed for a given muscle group no more than once per day (ideally, no more than once per 36 hour period). The initial recommended procedure for PNF stretching is to perform the desired PNF technique 3-5 times for a given muscle group (resting 20 seconds between each repetition). However, HFLTA cites a 1987 study whose results suggest that performing 3-5 repetitions of a PNF technique for a given muscle group is not necessarily any more effective than performing the technique only once. As a result, in order to decrease the amount of time taken up by your stretching routine (without decreasing its effectiveness), HFLTA recommends performing only one PNF technique per muscle group stretched in a given stretching session. How PNF stretching works. The isometric contraction of the stretched muscle accomplishes several things: The intense muscle contraction, and the fact that it is maintained for a period of time, serves to fatigue many of the fast-twitch fibers of the contracting muscles. This makes it harder for the fatigued muscle fibers to contract in resistance to a subsequent stretch. The tension generated by the contraction activates the golgi tendon organ, which inhibits contraction of the muscle via the lengthening reaction. Voluntary contraction during a stretch increases tension on the muscle, activating the golgi tendon organs more than the stretch alone. So, when the voluntary contraction is stopped, the muscle is even more inhibited from contracting against a subsequent stretch. PNF stretching techniques take advantage of the sudden "vulnerability" of the muscle and its increased range of motion by using the period of time immediately following the isometric contraction to train the stretch receptors to get used to this new, increased, range of muscle length. This is what the final passive (or in some cases, dynamic) stretch accomplishes.
Ballistic stretchingBallistic stretching uses the momentum of a moving body or a limb in an attempt to force it beyond its normal range of motion. This is stretching, or "warming up", by bouncing into (or out of) a stretched position, using the stretched muscles as a spring which pulls you out of the stretched position. (e.g. bouncing down repeatedly to touch your toes.) This type of stretching is not considered useful and can lead to injury. It does not allow your muscles to adjust to, and relax in, the stretched position. It may instead cause them to tighten up by repeatedly activating the stretch.
Dynamic stretching Dynamic stretching involves moving parts of your body and gradually increasing reach, speed of movement, or both. Do not confuse dynamic stretching with ballistic stretching! Dynamic stretching consists of controlled leg and arm swings that take you (gently!) to the limits of your range of motion. Ballistic stretches involve trying to force a part of the body beyond its range of motion. In dynamic stretches, there are no bounces or "jerky" movements. An example of dynamic stretching would be slow, controlled leg swings, arm swings, or torso twists. Dynamic stretching improves dynamic flexibility and is quite useful as part of your warm-up for an active or aerobic workout (such as a dance or martial-arts class Perform your exercises (leg raises, arm swings) in sets of eight to twelve repetitions. If after a few sets you feel tired -- stop. Tired muscles are less elastic, which causes a decrease in the amplitude of your movements. Do only the number of repetitions that you can do without decreasing your range of motion. More repetitions will only set the nervous regulation of the muscles' length at the level of these less than best repetitions and may cause you to lose some of your flexibility. What you repeat more times or with a greater effort will leave a deeper trace in your [kinesthetic] memory! After reaching the maximal range of motion in a joint in any direction of movement, you should not do many more repetitions of this movement in a given workout. Even if you can maintain a maximal range of motion over many repetitions, you will set an unnecessarily solid memory of the range of these movements. You will then have to overcome these memories in order to make further progress.

Injury Advice
Musculoskeletal Injuries / soft tissue inflammation How long will it take you to recover? Healing time depends mainly on blood supply. The blood brings the elements necessary for healing: Nutrients ~ think of injury as a remodelling job. Nutrients are the building materials for healing. Oxygen ~ This is the energy source for the project. You can not have fire without oxygen. The body can not heal with out oxygen.
Most body tissue, except the liver, heals with scar tissue. The Larger the injury, the bigger the scar. It is this biologic fact that explains why the body never totally "forgets" an injury.
Blood supply to certain parts is inherently better than to other parts. That is why injuries heal at different rates. Skin injuries to the face heal within a few days because the blood supply to the face is one of the best in the body.
Treatment of Muscular Injuries - An injury, whether in sport or elsewhere, will almost always result in bleeding. This may be obvious as in a cut or hidden as in a sprained ankle, corked thigh or any other torn or damaged tissue.
Irrespective of the cause of injury, the treatment is the same. The treatment can be divided into two parts.
1. The first aid type treatment: The acute stage:- immediately - 48 hours - apply RICE treatment,Rest, Ice, Compression, Elevation - Rest, Ice 10 on 10 off, compression & elevation. General massage can be applied elsewhere and away from the injury site to reduce swelling and prevent secondary problems developing. Aims of treatment: to prevent further tissue damage, ease pain, prevent loss of ROM, to regain full power and function.
2. Heal, Stretch & Strengthen. Sub/Post - Acute:- 72 hours - 6 weeks - when there are no more signs of inflammation & reduced swelling, this is the healing stage. Gentle massage can begin to prevent adhesions forming from scar tissue and any muscular imbalances occuring.
Chronic:- 6 weeks - 6 months - Long term - low term inflammation has continued for a considerable time, or large trauma in the past has not been given good treatment. This needs to be treated with much deeper friction in order to break it down, and deep longitudinal strokes will help to re-align the fibres.
During rehabilitation:- Deep massage will break down excessive scar tissue from injury, deep massage to all muscles associated with the injury site to find the root cause or contributing factors may be found.
Periosteum (periostitis), Dislocations, sprains, Fractures - See doctor first then massage is recommended.
"If in doubt - see a doctor"
