Repetitive Strain Injury (RSI) Explained

 

RSI is typically defined as an overuse disorder- a gradual build-up of overload to nerves, tendons, and muscles arising from repetitive movements or activities. Repetitive use of the same motions leads to inflammation and damage to these soft tissues. This disorder mostly affects the upper limb- particularly the elbows, hands and wrists.

 

Causes

Possible causes of RSI include but are not limited to:

  • Undertaking the same and repetitive movements and stressing the same muscle groups
  • Working in cold environments
  • Assuming a sustained and/or awkward posture for prolonged periods of time
  • Undertaking a particular activity for prolonged periods of time with no rest-breaks
  • Frequent and prolonged use of vibrating equipment
  • Adopting poor postures from working at inappropriately designed workstations
  • Undertaking a motion which involves carrying and/or lifting heavy items

 

 

Symptoms

RSI leads to a gradual development of a broad variety of symptoms, which range from mild to severe in severity. RSI particularly affects the muscles and joints of your wrists, hands, elbows, forearms, shoulders, neck. Having said this, RSI can affect other areas of the body as well.

Common symptoms may include:

  • Pain
  • Tingling
  • Cramping
  • Increased sensitivity to heat and cold
  • Tenderness
  • Fatigue
  • Loss of strength
  • Throbbing
  • Soreness
  • Achiness
  • Stiffness
  • Struggling with typical activities of daily living, such as gripping and twisting motions, carrying light weights, writing, kitchen prepping, dressing, personal cares etc

You may develop these symptoms when you undertake a task repetitively for a period of time, and can settle when you stop. Symptoms may settle over a few hours or over the course of a few days. However, if left untreated or is poorly managed, a minor RSI may gradually progress to a nasty chronic injury.

 

Diagnosis

 

If you experience mild discomfort whilst completing particular activities at home or at your job, it is a good idea to see your GP or physiotherapist to talk about RSI. But an RSI is not always simple to diagnose as there is no particular clinical test for it. Your GP will enquire about your medical history, occupation and work environment, and other activities to attempt to identify any repetitive motions you undertake that may be the cause of your symptoms. A physical examination will be undertaken, where they will assess your movement, check for pain, inflammation, sensation, tenderness, strength and reflexes in the impacted body part. RSI may be triggered by specific health disorders like bursitis, carpal tunnel, tigger finger, ganglion cyst, or tendonitis (inflammation in your tendons). Your GP can refer you on further diagnostic tests such as X-rays, Ultrasounds, blood tests, MRIs, nerve conduction tests etc, to determine if these underlying disorders may be the cause of your symptoms. You may be also be referred onto a physiotherapist and acupuncturist for conservative treatment and management for mild-moderate issues. If symptoms persist, you will then be referred onto a specialist.

 

Management

Initial treatment options for the management of RSI symptoms is conservative. This includes:

  • Rest, Ice, Compression, and Elevation (RICE principles)
  • Taking regular breaks between tasks and looking after your posture
  • Undertaking your activities and movements with appropriate form and posture
  • Intake of Nonsteroidal anti-inflammatory drugs (NSAIDs), both oral and topical as prescribed by the GP
  • Use of cold and heat to the impacted area
  • Administration of steroid injections into inflamed joints and tendons
  • Tailored exercise prescription from physiotherapists to correct posture and strengthen and stretch affected muscles
  • Acupuncture
  • Stress reduction and relaxation training
  • Use of splints and braces to help protect and rest the affected muscles and tendons

Ergonomically appropriate adjustments to your workstation and work environment may be recommended by your physio and GP- for example resetting your desk and chair if you’re working at computer, and alterations to your equipment and activities/motions to lessen the strain and stress on your muscles and joints. Surgery may be necessary in some cases.

 

Prevention

Minimizing repetitive actions particularly if they involve the use of heavy machinery or vibration. Improving your working posture and work-environment as well a taking regular breaks. Employers often undertake risk-assessments when you join a company to determine that the work area is ergonomically fit, comfortable and appropriate for you. You may be able to request for an assessment if you have not had one or are having issues with your work environment

Pressure on the Spine in Different Posture

Did You Know?

 

Low back pain is a common health problem which affects up to 80% of the population at some stage in their life.

 

In New Zealand ACC spends in excess of $130 million a year treating back pain related injuries.

Most back pain occurs between the ages of 25 and 60, and most typically in the 40s.

 

 

 

In an era of smart devices, posture has never been more important or harder to achieve. As technology continues to grow, sitting at a desk on a computer or on our phones is becoming more prevalent at work. Having a sedentary desk job can result in sitting for around 8 hours a day. This position actually increases the load on your spine more than standing. Spinal pressure “sits” around 140mm pressure. This pressure usually does not hurt the back right away however, builds up over time and can even change the structure structure of your spine. So, if you slouch then spinal pressure increases to 190mm; add some weight and you’ve put 275 pounds of pressure on your spine.

 

A compromised spine constricts your blood vessels and nerves, causing problems with your muscles, discs, and joints. And all of these problems can lead to headaches, fatigue, and even breathing problems. Your back is a delicate machine. When one part falls out of alignment, it can affect everything setting off a domino effect and wreak havoc throughout your back and body.

 

 


Below is a graph showing different postures and the pressure it exerts on the spine;


But, remember: While you may feel comfortable and supported in your chair and find a perfect sitting posture, staying in the same position for long periods is not healthy for your spine. Varying your postures by occasionally standing and moving around for at least a few minutes each half hour will help keep your spinal joints, muscles, tendons, and ligaments loose and pain free.

 

Stand Up for Your Spine

If you don’t have a sit-stand desk, you can still combat “sitting disease” and protect your spine. Consider these tips:

  • Do some work standing at a high table or counter.

  • Use a lumbar roll behind your back when sitting to improve seated posture

  • Set a timer on your computer for a stand-and-stretch break every 30 minutes.

  • Exercise to assist in improving body weight to lessen additional load on the spine

  • Strengthen the core to provide additional support

The focus is simple: Reduce your sitting throughout the day. But, remember that varying postures is best for your back and neck, so do not go the opposite extreme and never sit. Alternating sitting, standing and movement throughout your day is the best way you can keep your spine safe and body healthy—at work and beyond

 

Still having back pain?

Schedule an initial assessment with one of our Physiotherapists so they can determine the root of the problem.  During this assessment your physiotherapist will be able to decide whether your pain is a source of nerve root irritation, discogenic, postural related, or musculoskeletal.  After arriving with the consensus of the problem, we will be able to use many techniques to relieve the back pain.  These include: manual therapy, therapeutic exercise, and postural recommendations.

Do You Have a Healthy Work Station Set Up?

An ergonomically correct workstation has all the best practices to help maintain a healthy posture and improve your health and productivity.

Here are a few helpful tips;

1. Set up your screen

Adjust the monitor height so that the top of the screen is at—or slightly below—eye level. Your eyes should look slightly downward when viewing the middle of the screen. Position the monitor at least 20 inches (51 cm) from your eyes—about an arm’s length distance. If you have a larger screen, add more viewing distance.


2. Set up your chair

  • Height – You should be able to sit with your feet flat on the floor and your thighs roughly parallel to the floor. If you require a taller chair in order to reach the floor you can use a foot rest to ensure you achieve the right angle.

  • Backrest Recline and Tilt – Research has shown that a reclined seat (at least 135 degrees back)  significantly reduces the pressure on your back, and is particularity beneficial for people with back

  • Lumbar support – the shape of the backrest should have a natural curve to support your lower back.

  • Arm rests – Look for armrests that are not just height adjustable and support the entire length of the forearms.


3. Adjust your Desk Height

  • Your legs should fit comfortably under the desk if you are sitting with your feet flat on the floor: you should have enough space to cross your legs.

  • The angle between your forearm and upper arm should be between 90 degrees and 110 degrees while your arms are at rest on the desk.

  • Make your desk organized using storage accessories i.e. Document holders

  • Use an ergonomic mouse pad; to keep your wrists supported.


4. Organizing your Desk space

Organize all the items on the workstation according to their priorities and assign them to the proper ergonomic reach zones.

  • Primary Zone: High use items, easiest access

  • Secondary Zone :Medium use items, comfortable reach

  • Third Zone: Low use items, reduction in efficiency

:sparkles: MOVEMENT IS KEY :sparkles:

Its a simple action step, but mighty! Get up out of your chair and take frequent posture breaks!

When we sit in one position for hours without moving, our performance slowly starts to deteriorate, our body slows down, static loading takes over our muscles and we actually get fatigued even when we aren’t putting in any physical effort. However, when you consciously integrate these microbreaks into your day, you’re giving your body a much-needed refresher and an opportunity to wake up your muscles and replenish blood flow. Research has shown that movement can also help with creativity, or get you ‘unstuck’ so you can approach your work with a different or fresh perspective and energy.
