Repetitive Strain Injury (RSI)


RSI (Repetitive Strain Injury) can be a challenge to figure out and to reverse. Theories abound about how and why these injuries affect us. Most of these theories are based in the traditional medical model and the anatomical way of looking at and assessing injury.


What Is RSI and What Causes It?

Repetitive Strain Injury is exactly as the name describes. This class of injuries are caused by

Repetitive Movement + Strain

So, what does that mean for someone with an RSI?

Let's talk about the four most common injury-causers. When you see them, they will make a lot of sense to you. And, they are responsible for the lion's share of all upper body RSI's.

1. Poor Posture

The human body works best in a certain alignment. On your car, when the alignment of the front wheels gets out of balance, your car starts to shimmy and shake. This can then lead to front end damage, uneven wear on your tires, steering difficulties, etc. In other words, the car's systems start to break down and it costs you a lot of money to fix everything.

The human body isn't much different. Everything in your body is suspended in a matrix of connective tissue. This connective tissue, more commonly known as fascia, has the ability to change its consistency if strain is present. Normal fascia is very strong, but stretchy. It moves and gives with your every movement.

But, if your movement patterns are stressful, like when you have a slouched posture, or you have to constantly grip something heavy, fascia will start to become shorter and tighter, less resilient, and less stretchy. You begin to feel stiffer. It becomes harder to sit or stand up straight. Some movements may become uncomfortable or even painful.

If the fascia that is affected by your posture happens to wrap a nerve, you are more likely to develop nerve symptoms of Repetitive Strain Injury like numbness and tingling. If the fascia that is affected by your posture is embedded in muscle, you will be more likely to feel more restricted in your movements and you will more likely develop muscular symptoms of RSI like weakness and muscle pain.

2. Stress

I am sure you have had the experience of being under stress. We all know that feeling. If you pay attention to how you feel when you are stressed out, you will probably notice that your body tightens up, your movements become tighter and more rigid, your breathing slows way down and becomes very shallow.

All of these examples will cause strain to your fascia. And, once the stress and strain have gotten a foothold, it becomes difficult to know what came first, the stress or the feeling of strain. They begin to go hand-in-hand. One will perpetuate the other.

What I mean by that is when you feel stress, your muscles will tend to tighten up. This will send a message to your fascia to also tighten up. Once your body feels tight, your brain begins to associate it with feelings of stress, so your posture and your movements will begin reflecting that feeling. Stress causes strain, which causes more stress which leads to even more strain and around and around we go.

If you are doing something repetitive or that requires strain while you are experiencing this stress, you will develop a repetitive strain injury even faster.

3. Injury

All injuries, the recent as well as the very old, are recorded in your body's connective tissue system, the fascia. Fascia is the stuff that holds you together. It connects everything under your skin with everything else. It transmits movement so that one part of your body knows and follows along when another part moves. It allows muscles to slide and glide alongside one another. It forms a protective tube so that nerves and blood vessels can move in and between muscles, skin and bone without getting irritated.

When you are injured The fascia actually changes at the moment of injury and remains tighter and more restricted in an effort to support your injured body. It's a very natural fail-safe mechanism that all bodies share.


Have you ever broken a bone? Once your cast comes off, you probably noticed that you feel much stiffer, you have lost range of motion, your muscles feel thicker, shorter, less healthy. This is due to the changes in the fascia that permeates your muscles. They have changed due to the inactivity of being in a cast, which is stressful.

Your injury can also include surgeries, cuts, internal tears, etc. The fascia forms scar tissue in response to this kind of injury. If you have ever palpated a bit of scar tissue on your body, you know it is thicker and denser than the surrounding tissue.

A helpful example of how this works is to think about a pullover sweater, the kind that is solid in the front, with no buttons or zipper. If you pull the sweater in any direction, it will pretty much give easily in that direction. You will also notice that the effect of the pulling is shared equally with all the threads along the pathway of the pull. The movement caused by the pulling is transmitted equally throughout the sweater.

Let's say you take a scissors and cut a 2 inch slit in the front of your sweater. Because of the interconnectedness of the sweater's fibers, you must stitch the hole closed or the sweater will unravel. When you stitch the slit closed, you begin to notice that the sweater can no longer stretch easily and equally in all directions. It is inhibited by the sewn-up tear.

It's the same story with fascia, When it is cut as happens in any surgery, cut or tear, it must knit itself back together to maintain the integrity of the whole system of fascia. This is because one of fascia's jobs is to transmit movement through your body. So, when you have a cut of some kind, the fascia will knit itself back together very quickly.

This is how scar tissue forms after an injury. The result is that the repaired tissue no longer stretches easily and equally throughout the sheet of fascia, just like the repaired sweater. This now becomes a source of stress to your body and it responds by building up more restricted tissue.

4. Personal Habits

We all develop movement habits that eventually become pretty unconscious to us. Here are a couple of examples of what I mean.

Take the Mom who always holds her babies on the same hip. Over time, she probably doesn't realize that her baby-carrying hip is higher than the other hip, causing structural stress inside her body.


A salesman who carries a heavy sample case is at risk too. Most of the time, we develop habits of carrying heavy loads with the same hand. Our body slumps in the direction of the load. Over time, this salesman doesn't realize that his body tilts to the side of his heavy sample case. More structural stress.

Holding a phone between your chin and shoulder is also another really common culprit. The shoulder hikes up and the neck tilts to one side causing a lot of stress in the neck and shoulder. This one can create a whole host of problems because big bundles of nerves also pass through the same area of the body. This means that when the fascia changes there due to the stress, the nerves passing through the region become trapped in the thickening and tight fascia. BIG problems start to show up then.


If You Think You Have A
Repetitive Strain Injury...

These are the four most common sources of structural stress that can lead to a repetitive strain injury. It's not hard to imagine that if you begin combining several of them together into your body history, unraveling them to discover what is the actual cause of your RSI can become tricky. In almost every case, an injury is due to several of these causes, affecting multiple parts of the body.

When you approach a recovery system for your case of RSI, be sure that you approach it from several directions, looking at all the possible causes - the recent to the very old. Think about what you are doing when you feel pain, weakness, tingling or numbness. Have you felt that before? When was the first time you felt that sensation?  What were you doing then?

Because your body's life history is recorded in the connective tissue of your body, your job becomes that of detective - figuring out what you feel and when that began. This will lead you to clues about the nature of your injury, what aggravates it, what makes it come and go, and ultimately, what you need to do to recover. To ignore one of the causes could be an invitation to delayed results, poor results, or no results.

A New Perspective On RSI

On this website, we will look at repetitive strain injury in a whole new light - from the perspective of the fascia (connective tissues) of the body. Once you learn more about this critical and often overlooked tissue, you will understand that there are real solutions possible. There is hope for a real and complete recovery from your repetitive strain injury.

When you have a repetitive strain injury, most people will be frustrated because their symptoms don't perfectly match the typical symptoms of the injury they have been diagnosed with. Believe me, that is very, very common. The reason that is so is because it is the fascia that is actually the injured part in any RSI and fascia is everywhere under your skin. How you were injured and what you were doing when you were injured, or what you have patterned into your connective tissue just by living your life will affect the fascia in your body in unique ways. And this can lead to confusing symptoms that are different from the textbook definitions of your injury.

In the self care toolkits that are offered on this website (see each injury section to find the links to the Toolkit you might need), this unique characteristic of fascia is taken into consideration. All the information and techniques offered will help restore injured tissue back to a more normal condition even if your symptoms differ from the typical symptoms of the injury that you or your doctor think you have.

This website will offer information and insight into seven of the most common upper body RSI's. The goal of this website is not to diagnose or cure your RSI. Instead, the goal is to restore your injured fascia back to a more normally functioning condition so that your body can heal itself. By helping your body in this way, you can reverse your symptoms quickly, safely and comfortably in the comfort of your own home. What could be better than that?

The injury types covered on this website include:


- Carpal Tunnel Syndrome

Carpal Tunnel Syndrome is one of the injuries that affects a nerve, in this case, the Medial Nerve of the arm. This section is helpful for people who experience pain, numbness, tingling, or weakness of the thumb, index, middle (and sometimes part of the ring) fingers. It is often accompanied by pain or weakness in the forearm and wrist as well. 

- Thoracic Outlet Syndrome

Thoracic Outlet Syndrome is another nerve-related condition. In this case, the whole nerve bundle (the Brachial Plexus) that serves the arm is affected. This means that if you have TOS, your whole arm and hand may be numb, tingling, weak. You may have circulation problems as well in your hand or arm, often when putting your arm in specific positions.

- Ulnar Tunnel Syndrome (also known as Cubital Tunnel Syndrome)

Ulnar Tunnel Syndrome is the third nerve-related condition covered on this website. In this case, it is the Ulnar Nerve that is affected. This nerve serves the outside of the forearm from elbow to wrist, as well as the ring and little fingers. Symptoms of numbness and tingling will often develop from resting the forearms or wrists on the edge of a desk or table.

- Forearm Pain

People who experience Forearm Pain will often have to deal with fatigue or weakness of their forearms, making their hands and fingers weak. The interesting thing is, they are not actually weak at all. The muscles of the forearms have just developed adhesions which limits the muscle's ability to work properly. Once the adhesions are released, strength improves rapidly. This is welcomed news to rock climbers, parkour, and other sports enthusiasts. There is no numbness or tingling associated with Forearm Pain.

- Neck and Shoulder Pain

From a kink in the neck, to pain between or under the shoulder blades, headaches from tension and limited range of motion of the head and neck, this section will help you find solutions. There is usually no nerve related numbness or tingling with Neck and Shoulder Pain as it addressed in this website.

- Elbow Tendonitis

Elbow Tendonitis is often confused with Forearm Pain because some of the tissues that create the pain in Elbow Tendonitis are right next to tissues that are implicated in Forearm Pain. The tendons at the elbow are the issue here and problems with them will generate the symptoms known as Golfer's Elbow or Tennis Elbow. Pain is usually felt when exertion or force is transmitted through the elbow, like when swinging a tennis racket or hitting a golf ball. There is usually no numbness or tingling associated with Elbow Tendonitis.

- Thumb Pain (also known as DeQuervain's Syndrome)

Thumb Pain, also known by its official name of DeQuervain's Syndrome, is becoming a huge phenomenon in today's modern world. With the ever-present strain of texting or using a cell phone, computer or tablet, the thumbs are under constant threat of injury from overuse. With so much constant motion and strain, the tiny muscles of the thumbs become overwhelmed, leading to pain in the thumbs and extending through the wrist and into the forearm. There is usually no numbness or tingling associated with Thumb Pain (DeQuervain's Syndrome).



The Role Of Fascia

In every case of RSI, fascia plays a major role in the symptoms you feel and the changes that take place in your body. Therefore, it is imperative that you address the role fascia plays in your injury if you have any hope for a true recovery.

This website focuses on the fascia of your upper body, how your symptoms are generated and what is needed to restore damaged or altered fascia back to a more balanced, more optimum condition. By attending to this aspect of your RSI first and achieving the desired restoration of your fascia, your symptoms will be significantly reduced or may disappear altogether. Then, any additional recommended therapy you incorporate in your recovery program will work better and faster.

Be sure to visit the section on Fascia to learn about its role in your injury. Then, proceed to the pages that relate to directly to the type of RSI you are experiencing for more specific information and guidance.
