Overuse Injuries & Repetitive Stress Injuries (RSI)

Overuse Injuries & Repetitive Stress Injuries (RSI)

Overuse injuries occur when a repetitive motion begins to cause discomfort, without one traumatic event occurring. Usually, these disorders have an insidious onset and slowly increase over time, and seem to improve with rest. These types of injuries can occur with muscles, tendons/ligaments, bone or nerves in every joint in the body. Repetition of certain movements or postures creates increased stress, or load, on the body. Below are a few examples of overuse injuries:

  • If a muscle is overworked and becomes fatigued, it cannot function as effectively, leading to potential muscle strains.
  • If a muscle is constantly being used, its insertion point into a bone, known as a tendon, is under regular strain and can become inflamed, known as tendonitis. 
  • Bones that are consistently placed under too much stress can also become injured, known as a stress fracture, which commonly occurs in runners. 
  • While you do not need to be a tennis player in order to be diagnosed with tennis elbow, the repetitive motion commonly associated with swinging a tennis racket can eventually lead to pain in the elbow. 
  • Baseball pitchers are more susceptible to shoulder injuries because of the constant pull placed on the joint and surrounding structures. 
  • Even sitting at a desk for many hours each day can result in discomfort, such as carpal tunnel or back pain.

Symptoms of Overuse Injuries & Repetitive Stress Injuries

The first signs of an overuse injury may be soreness, tingling or discomfort in the neck, arms, wrists, fingers or shoulders. These symptoms may come on when you do something or appear afterwards. They may disappear when you stop the activity that brought them on. It may take only a few hours for the symptoms to go away, or it may take as long as a couple of days. If it isn’t treated successfully, RSI can turn into a chronic pain problem.

  • Challenges with everyday activities like opening doors, chopping vegetables, and using faucets
  • Persistent coldness in the hands, especially in the fingertips
  • Experiencing burning, aching, or shooting pain in the neck, shoulders, upper back, forearms, wrists, hands, or fingers
  • Symptoms such as tremors, clumsiness, and numbness
  • Fatigue and reduced strength
  • Weakness in the hands or forearms, making even basic tasks like lifting a shopping bag difficult

Causes of Overuse Injuries & Repetitive Stress Injuries

Overusing your body is the main cause of repetitive strain injury. Contributing factors include:

  • doing something with your arms repeatedly for too long
  • working with equipment that doesn’t fit your body
  • working too fast
  • not having breaks
  • holding your muscles in the same position for a long time
  • lack of training in the safest way to carry out a task
  • long work hours
  • lack of variety in the type of work you do
  • working in cold conditions

The underlying cause common to all RSI-type conditions is damage to muscles and tendons (and the nerves that run through them) through repeated micro-trauma. Whenever muscles are used, tiny tears can occur in muscle tissue. The local area becomes inflamed for a short time as the body attempts to repair the damage.

Without enough rest for the damaged area to be repaired fully, more activity causes further damage and more inflammation, thickening, scar tissue and pain.  Nerves are also damaged by RSI. Tingling feelings are caused by the compression of nerves. Nerves run through muscles, and if muscle health is poor, so is nerve health. Damaged nerves can heal but the process is extremely slow.

Treatment

Start your journey to better well-being by seeking an evaluation from one of our physical therapists at the Hobson Institute. We specialize in assessing daily movements that may lead to overuse injuries and can teach you strategies to reduce repetitive motions or safely increase activity to prevent these stress injuries. Our approach includes strengthening surrounding areas and reducing inflammation in affected joints through physical therapy.

One common area prone to overuse is the head and neck muscles, often due to poor computer posture and mouse usage. We’ll guide you in achieving a safer, more neutral body position to relieve strain on these overloaded muscles and joints. Our tailored approach incorporates a carefully graded strengthening exercise program, manual therapy, massage, dry needling, gentle stretching exercises, osteopathy, and breathing exercises to address your specific needs.

Heat, ice, ultrasound, electrical stimulation or athletic taping may be part of your physical therapy program as well. Your physical therapist can also provide advice on the use of braces, orthotics and assistive devices. Your physical therapist will also work with you to create a comprehensive home exercise program that will help you maintain your quality of life beyond your therapy sessions.

Frequently Asked Question

Find a good doctor, one who is both knowledgeable with overuse and repetitive strain injuries which may or may not be the GP you normally use. 

Come see us at the Hobson Institute to get someone on one care to help eliminate the repetitive activities that you may not realize you are doing and get the care you need to alleviate your joint and muscle pain.

Try to get some time away from work, as rest can cure the injury in the early stages. At the same time, get as much exercise you can – walking, running, cycling, anything that gets your blood flowing.

Have a really good look at your workstation and try to decide what needs fixing. Do you have the right desk, keyboard and monitor setup? Are you working too hard? Are you stressed at work? Do you get regular breaks?

Take this injury seriously – many people end up permanently injured.
