Choosing & Using a Wrist Rest

There has been some debate over wrist rests and whether they do more harm than good. The question really comes back to proper usage, as do most ergonomic questions. If, for example, you buy a a travel pillow and then cock your head awkwardly to use it, it's not really the pillow that is at fault- it's your usage.

The purpose of a wrist rest

As more and more workers type for long stretches at a time, the number of complaints about RSI, such as Carpal Tunnel Syndrome, has gone up as well. That is because most people do not know how to type ergonomically: they drop their wrists to the desk surface, cock their wrists to type, keep the mouse too far away, and do any number of things that put strain on their wrists, hands, and forearms. A wrist rest is a padded strip of material meant to meet your wrists and heels of your hands so that they don't have to drop down to rest. Essentially, a wrist rest catches the heels of your hands so that you don't feel pain in your wrists.

How to use a wrist rest

Ergonomic studies tell us that wrist rests should be used between periods of typing to rest your wrists. So, line up the wrist rest in front of your keyboard so that there is not a drop off between it and the desk. Then, as you type, try to float your hands over the keys and not cock or hyper-extend them. As you pause, rest your wrists on the wrist rest.

Ten Tips for Relieving Shoulder Pain

The shoulder is a complex joint. It has the widest range of motion for any joint in the body, and is carefully held together by muscles and other soft tissues, such as tendons and ligaments. Because of the high mobility and immense complexity, this joint is very susceptible to discomfort and injury. One of the leading causes of shoulder pain is poor posture and overuse, often associated with everyday computer use. Try these ten tips for relieving shoulder pain.

1. Take a break. Make it a habit to stop your regular activity for a few minutes every hour. Get up from you chair and walk around. If you have non-computer tasks, spread these throughout the day to provide longer breaks from your computer.

2. Stretch the sore muscles. During your breaks, or even more frequently, stretch your shoulder muscles. Try these stretches recommended by the National Institute of Health, or these quick stretches.

3. Apply hot or cold compresses. Heat will increase blood flow to the area and relax tense muscles; do not apply heat to an inflamed area. For inflammation, cold packs can numb the pain and reduce swelling; do not to apply ice directly to the skin. Use this treatment no longer than 20 minutes at a time and only once an hour.

4. Adjust your chair. This is the foundation for good posture at your desk. First, assess the back rest of the chair. If it does not properly support your lower back, additional lumbar support may be needed. Next, change the height of the chair; your feet should rest flatly on the floor. Finally, lower the armrests in order to allow free, relaxed movement of arms and shoulders while using a keyboard or mouse.

5. Customize your work space. Shoulder pain is frequently caused by improper placement of keyboard and mouse. An adjustable tray can help place the keyboard at the optimum position slightly below elbow height, one to two inches above the legs. Place the mouse as close to the keyboard as possible, to avoid stretching to reach it. An ergonomically designed mini keyboard would allow the mouse to rest in the best position.

6. Re-situate your monitor. It should be directly in front of you at eye level. A monitor stand can provide the required height. The screen should only be 15 to 25 inches away from your eyes, so you don’t lean forward to read.

7. Try a phone headset. Frequent phone use can cause neck and shoulder strain, especially when holding the phone between your shoulder and ear. A headset can allow hand-free operation without the muscle strain.

8. Dock your laptop. It is impossible to achieve good posture while using a laptop. If you use a laptop for long periods of time, use a docking station that allows for the proper keyboard and monitor positions.

9. Build shoulder strength. Regular exercise can relax muscles and relieve stress. The National Research Center for the Working Environment used these five strength-building exercises to provide relief for shoulder pain.

10. Get medical advice. If your pain is related to an accident or fall; or if you also have chest pain, nausea, or shortness of breath, consult your doctor immediately.

Shoulder pain is often caused by poor positioning and overuse of the muscles. These ten tips can help restore proper posture at your office desk, relieve current discomfort, and prevent future injury and pain.

Improper posture and lead to shoulder pain.

The Shoulder is a wonder combination of several joints that are connected with tendons and muscles for a wide range of motion of the arm. Pain in the shoulder region is due to various reasons. Most painful shoulder problems have a link with injured soft tissues, muscles, ligaments and tendons, rather than just bones. Pain in shoulder falls in three major categories namely Tendinitis, injury and Arthritis.

Shoulder pain is also caused by tumors, infection and nerve-related disorders. A tendon is a cord which connects muscle to bone or other tissue. The splitting and tearing of tendons due acute injury causes pain. Excessive use of the shoulder leads to inflammation and swelling of a bursa, known as Bursitis.

Treatment of shoulder pain depends on the injury and gravity of the injury. The shoulder joint is the prone to frequent dislocation and is referred to as shoulder instability. Technically, shoulder dislocation is referred to as Luxation and partial dislocation as subluxation.

Dislocation of the shoulder is treated by putting the head of the humerus back into the joint socket called the Glenoid Fossa of the scapula by manipulation and reduction (M&R) procedure followed by an X-ray study. The arm is then immobilized in a sling or a shoulder immobilizer device. Severe dislocation injures the surrounding tissues or nerves and is treated by surgery.

The Glenohumeral joint or the shoulder joint stability depends on a group of muscles called the Rotator Cuff. The Rotator Cuff muscles help shoulder stability and control during joint rotation. The Rotator Cuff Muscles include Supraspinatus, Infraspinatus, Teres Minor and Subscapularis. Sports that demand active and vigorous rotation of the shoulder joint often put these Rotator Cuff muscles under strain causing pain. Pain due to Rotator Cuff muscles strain can occur either due to tears of the muscles or inflammation

The Shoulder Joint is the area where the collar bones Clavicle and shoulder blades Scapula are connected. Pain in this region could be due to Ankylosis,Arthralgia, Cartilage Disorders, Infection, Shoulder Joint Dislocation, Shoulder Joint Capsule Damage, Acromioclavicular Arthritis, Bicipital Tendonitis, Rotator Cuff Tendonitis, Subacromial and Subdeltoid Bursitis. There are three common problems associated with shoulder pain namely, Instability, Subluxation, OveruseandArthritis Degeneration.Instability is a condition where the joint is completely out of position and subluxation is partial dislocation.

Arthritis is a painful inflammatory condition in the joint region. Osteoarthritis is the most common type of Arthritis. Rheumatoid Arthritis, Psoriatic Arthritis and Septic Arthritis caused by infection, Gouty Arthritis caused by Uric Acid deposits in the joint region and Pseudogout, caused by deposition of Calcium Pyrophosphate crystals also cause painful inflammation. Periarthritis, Adhesive Capsulitis, also popularly known as frozen shoulder also cause chronic pain in the shoulder. Physical therapy is useful as a treatment option for people with shoulder pain.

Physical therapy includes daily walking and stretching exercises. Traction and massage of joints enhance joint mobility and flexibility. Information regarding the treatment options can be obtained from a doctor based on the signs of the disease. Investing in a back support for your chair can alleviate shoulder pain.

Is Your Desk a Good Fit For Ergonomics and Productivity?

When it comes to your desk one size certainly does not fit all. Let’s face it, we all come in different shapes and sizes and what fits one may not necessarily fit another person. Is like going over to Grandma’s and trying on her clothing at the age of seven. Even a seven year old knows that Grandma’s cloths are not going to fit. Your desk and office equipment you use is no different. For optimal ergonomics and productivity, your desk, chair, and equipment should be designed and arranged so that it suits your body and the work you do.

When you are sitting at your desk ask yourself whether or not it is adjusted right to match your build. Also determine whether it is ergonomically designed to allow for adjustment. There is no one-size-fits-all desk, so you need to pick a desk that can be adjusted to suit you and your work habits.

A well adjusted desk allows your legs to move freely around without colliding into other objects. The height of the desk should be such that it has room beneath the desktop to allow your knees plenty of space. If your desk is too high and cannot be lowered then consider getting a footrest so that your legs will be comfortable and not have to dangle in the air.

Also be sure to keep the area under you desk clutter free. When the area underneath your desk is uncluttered your legs will be unrestricted; thus, minimizing pain in the ankles and joints. To reduce the probability of injury you can also get an organizer.

An organizer keeps all your documents and electronics in an easy to reach and out-of-the-way location. I often see a lot of desks that look as though they just got hit with a tornado and I wonder how one ever functions productively in such an environment.

A good fit between you and your desk will do wonders for your productivity. You can find things that much faster and avoid needless bumps and bruises caused by clutter underneath your desk. You can save yourself tons of headaches by keeping your desk ergonomically friendly.
