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

EASY STRETCHES DESK STRETCHES

Sitting at a desk working, studying or surfing the net for long hours at a time makes it extremely difficult to maintain proper posture. That’s because our bodies are not designed for hours of idle sitting. So as the clock gets ticking many of us have the tendency lean forward, slouch our shoulders and hunch our backs.

Unfortunately, this increases pressure on multiple areas in your body. This explains why most of us experience pain and stiffness in our neck, shoulders, back and in some cases your tailbone!

So what do I need to do you ask?

The answer is simple, STAND, MOVE AND STRETCH!

It sure does sound easier said than done, especially if you are pressed with time to complete set work tasks. BUT the good news is that stretching or moving is a buildable habit that can be easily implement as you work. It doesn’t take long!

For starters set an alarm to take micro 2–3-minute break for every 20-30 minutes. Use this time to stand up, walk over to a colleague, go for a toilet break, drink water or make yourself tea or a coffee.

Or try out these simple easy stretches while you sit or stand at your desk

Carpal Tunnel Syndrome – What is it?

Have you been experiencing pain, pins and needles or numbness in your wrist and hands, especially after using the keyboard, chopping up a few veges, reading a book, using your mobile phone or with driving?

If you answered yes – then you are most likely to have Carpal tunnel syndrome.

What is Carpal Tunnel Syndrome?

Carpal tunnel syndrome is the most common condition in the arm. It is caused by compression of one of the three major nerves in the forearm – the median nerve, which travels through the wrist into the hand and fingers. Entrapment of the median nerve usually due to inflammation, occurs in the wrist commonly resulting in tingling of the wrist and hand (in some cases forearm), numbness, pain and weakness of the hand.

Signs and Symptoms

Often unrelated to a specific incident or an injury, symptoms of carpal tunnel syndrome usually develop gradually overtime. Symptoms may be worse in the morning and night. Many people find that the frequency and duration of symptoms increase as the conditions worsen.

Signs and symptoms may include:

  • Tingling, numbness or burning sensation of the thumb, index, middle and ¾ of ring fingers of the hand
  • Electric shock like radiating pain through the hand into thumb, index, middle and ¾ of ring finger
  • Weakened grip, loss of dexterity and fine movements such as picking up a hair pin, buttoning clothes.
  • Hypersensitivity or in other cases lessened sensation of hand to pressure, heat or cold temperatures
  • Swollen wrist

Let’s take a closer look at the anatomy!

As its name suggests – a group of small bones aka carpal bones form a tunnel like passageway in the wrist (palmar view). This unique architectural design allows for the tendons of the forearm muscles and the all-important median nerve to pass through the narrow tunnel through the wrist and into the hand and fingers, supplying sensation and motor function.

Causes

Common causes and risk factors that increase the likelihood of carpal tunnel syndrome include:

  • Repetitive wrist & hands movements – during work related tasks or leisure activities may irritate the tendons in the wrist, resulting in inflammation that irritates the nerve.
  • Wrist or hand injury – recurring sprains, swelling and reduced wrist movements reduces the space in the carpal tunnel
  • Pregnancy and menopause – hormonal changes can increase fluid retention in body increasing pressure in the carpal tunnel compressing the median nerve
  • Genetic history – petite
  • Medical conditions (rheumatoid arthritis, diabetes, hyperthyroidism)

Interesting facts about carpal tunnel syndrome

  • Women are 3 times more susceptible to develop carpal tunnel syndrome than men. This can be due to hormonal changes during pregnancy or menopause and also because women tend to have smaller carpal tunnels.
  • Not all fingers are affected. Median nerve supplies movement and sensation in the thumb, all fingers except the little finger.
  • Computers/keyboard are not the only reasons to blame – repetitive nature of any work related or leisure word increases risk of developing carpal tunnel syndrome

Diagnosis

Carpal tunnel syndrome is fairly easily diagnosed by your physiotherapy, doctor or a hand therapist.

Your health practitioner will gather information on your general health, history and nature of your symptoms. They will then carefully conduct a thorough clinical assessment to assess the movements of your hand and wrist, strength and use a collection of tests in effort diagnose your symptoms. In some cases, your therapist may examine your neck, shoulders and arms to rule out other potential causes.

You may often hear the physiotherapist or hand therapist mention that they want to conduct a functional assessment – A functional assessment is activity specific, where the therapist will watch you perform the activity that aggravates your symptoms the fastest. For example, if using a keyboard is generally when you feel your symptoms start – the therapist may observe you performing the very task to examine your overall posture.

Referral to scans or nerve conduction tests may be arranged by your doctor or therapist depending on the severity or complexity of your symptoms.

Scans

Referral to scans or nerve conduction tests may be arranged by your doctor or therapist depending on the severity or complexity of your symptoms.

  • Xray – provides key information on bone health, when dealing with a potential injury, or arthritis
  • Ultrasound – can examine potential soft tissue injury or inflammation compressing the median nerve
  • MRI – this advanced imaging provides in depth review of your wrist and hand. Usually arranged by your doctor or a specialist
  • Nerve conduction study – studies the electrical activity of the median nerve. This test will help you doctor examine the severity of your problem.

Treatment

In most cases, carpal tunnel syndrome will progressively worsen overtime. So, the key is early intervention!

Conservative management

Mild symptoms can be easily managed with a conservative approach.

  • Wearing splints or braces – keeps your wrist straight to prevent repetitive use of hands, thus reducing pressure or inflammation in the carpal tunnel.
  • Non-steroidal anti-inflammatory medications – such as celecoxib and ibuprofen as prescribed by your doctor may decompress the median nerve by reducing the inflammation in your body and wrist.
  • Activity modification: your physiotherapist will play an important role in providing you with advice around to modifying your activities to reduce your symptoms. They will also prescribe you with effective stretches and exercises to help manage your symptoms while safely aiding your recovery.
  • Steroid injections: your physiotherapist or doctor may recommend a ‘cortisone’, also known as a ‘corticosteroid’ injection to control your symptoms. It contains an anti-inflammatory substance that is injected into your carpal tunnel. The effects of the steroid injection may be temporary and can vary person to person depending on many factors (cause of symptoms, stage of your condition).

In mild to moderate cases, the effects of injection may last between 3-6months.

Surgical intervention

If non-surgical approaches have failed to relieve your symptoms, surgery may be required.

By this stage you would have consulted an orthopaedic surgeon. Your surgeon will thoroughly examine your overall health, symptoms, results from the scans and the nerve conduction study to help you decide on the best treatment approach.

If you decide to undergo surgery – the surgical procedure your surgeon will perform is called ‘carpal tunnel release’.

Recovery and outcomes

  • After your surgery you may be given a splint or a brace for a period of time specified by your surgeon. While in the splint or brace you will be encouraged to move your fingers to prevent stiffness and swelling.
  • Expect to experience minor pain, stiffness and swelling for a couple of weeks to months after your surgery. Pain medications provided by your surgeon must be taken as prescribed.
  • You may be encouraged to see your physiotherapist, who will work closely with your surgeon to help meet post-operative outcomes.
  • You will have regular 6-8 weekly follow ups with your surgeon as required to assess your healing and discuss gradual return to light activities and return to work.
  • If you have underlying medical conditions such as arthritis, except that your recovery may be slower than otherwise expected. It is important that you follow post-operative protocols your surgeon, doctor and physiotherapist recommend.
