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

Piriformis Syndrome

Piriformis syndrome refers to the dysfunction of the piriformis muscle which irritates the sciatic nerve. It is characterized by deep buttock region pain that radiates down leg and foot often accompanied by pins and needles and numbness traveling along the path of the sciatic nerve.

The simplistic reason for this widely distributed pain comes down to the piriformis muscle itself – Their close proximity means that direct trauma to the buttock region or the supporting structures can result in inflammation and muscle dysfunction which can compress and irritate the sciatic resulting in referred symptoms.

Piriformis syndrome symptoms may include:

  • Localised deep buttock region pain
  • Pain with continuous sitting or standing for 15 mins or over
  • Pins and needles along the leg down to the outer foot
  • Numbness in outer leg or foot (often resolves on movements)
  • Deep squatting or bending
  • Pain on direct palpation

Anatomy

 

The piriformis muscle originates from the outer surface of a large fused bone of our pelvis called the sacrum. It travels adjacently and inserts into the top of the hip joint. The piriformis muscle is a very active muscle involved in stabilizing the hip and pelvis during majority of our activities (walking, running, standing, sitting or standing, turning in bed). When the piriformis muscle contracts it helps the hip rotate outwards (external rotation) and lift thigh out and up (abduct).

The sciatic nerve originates from where the very base of the spine and the sacrum join known as the lumbosacral region (lower back and saddle region). In this region five separate branches of nerves travel outside of the bony openings of the spine called the nerve roots and connect into a single large nerve – the sciatic nerve. It then travels through the pelvis deep into the buttock region close proximity the piriformis and gluteal muscles. In some individuals the piriformis muscles can travel through the piriformis muscle subjecting them to piriformis syndrome.

Diagnosis

There are no specific tests to diagnose piriformis syndrome. Diagnosis of piriformis syndrome is made by the report of symptoms and by physical exam using a variety of movements to elicit pain to the piriformis muscle. In some cases, a contracted or tender piriformis muscle can be found on physical exam.

In cases where there is underlying pathology (such as disc injury, arthritis, sacroiliac dysfunction or hip injury) resulting in true sciatica – piriformis syndrome may develop to become an additional muscular dysfunction that is required to be addressed. Because symptoms can be similar in other conditions, radiologic tests such as MRIs may be required to rule out other causes of sciatic nerve compression, such as a herniated disc.

Consultation with a physiotherapist in this case is highly recommended as they will perform a comprehensive clinical examination to identify the root cause of your symptoms.

Exercises for piriformis syndrome

Corrective exercises with a combination of strength and flexibility regimen is an essential way to treat true piriformis syndrome (without involvement of other underlying pathologies).

The exercises outlined below follow a phase-by-phase progressive regimen to strength key muscles of the hip, buttock and legs.

As you work through these exercises expect to feel some pain during and after your exercise. Pain you may feel during the exercise is an expected sign of muscle activity. Pain you may feel after the exercises is an expected sign of muscle healing and recovery. However, if you are unable to participate in the exercises due to symptom deterioration – it is highly recommended you consult your physiotherapist to rule out other potential causes.

Otherwise, to help you gauge the correct amount of pain you should expect during exercise – use this scale. The ideal range should be 2 to 5. If your baseline pain is over 6 or 7 – it is recommended that you consult your doctor for pain relief appropriate to manage your pain, followed by a consult with a physiotherapist. Your physiotherapist will be able to modify the following exercises or prescribe alternative exercises best suited based on your current level of function and symptoms.

Symptom noting – is a great way to keep track of your progress and symptom behaviour.

  • Take a diary
  • Note down pain before you begin the exercise.
  • Note down the pain rating after each exercise.
  • Note down pain at the end of the day
  • Repeat the pain recording process for the next 4-5 days
  • Examine the trend in your symptoms.

Interference with everyday tasks – Your participation or level of exertion with everyday activities may interfere with your symptoms impacting your exercise tolerance. It is therefore important to note any of these interferences’ contributory to your pain.

Phase 1 – is a beginner stage.

This phase is intended for gently priming muscle activation. It will demand your concentration on technique and compliance to change the possible compensation your body has been used to as a result of pain. This phase can last between 1-2 weeks.

Instructions:

3 sets of 10 repetitions. Hold each repetition for 8-10 seconds. Rest 10-15 seconds between sets, 30 seconds between exercises. Do this exercise 1-2 times per day.

Bridges

 

Lie on your back.
Bend both knees and place your feet flat on the bed.
Lift your buttocks from the bed.
Place your buttocks back on the bed.
Repeat this exercise and remember to continue to breathe properly.


Clam shells

 

 

 

 

 

 

Lie on your side with your feet, ankles and knees together.
Bend the legs a little and tighten your core stability muscles.
Keeping the feet together, lift the top knee up.
Make sure you don’t roll your body back with the movement.
Control the movement as you bring the knee back down to the starting position.


Phase 2 – intermediate stage

The intermediate phase is similar to the beginner stage with the difference of using changing elements of progression to challenge the muscles capacity further. In this stage you may choose to progress the exercises by choosing to change ONE factor:

  • Increase repetitions
  • Increase hold time
  • Increase sets
  • Add appropriate resistance

Instructions:

  • 3 sets of 10-15 repetitions. Hold each repetition for 10-15 seconds.
  • Rest 10-15 seconds between sets, 30 seconds between exercises.
  • Do this exercise 1-2 times per day.

Bridges with resistance

 

 

 

 

 

 

 

Tie a resistance band around both thighs, just above your knees.
Lie on your back with your knees bent and legs hips width apart.
There should be tension in the band.
Raise your hips up into a bridge, keeping the knees hips width apart.
Control the movement back down to the start position, maintaining constant tension on the band.


Clams with resistance

Lie on your side and place a band above your knees, approximately an inch or two above the knee joint.
Bend your legs a little, keeping the feet in line with your back.
Use your core stability muscles to keep the body stable.
Keeping your feet together, lift the top knee up against the resistance of the band.
Ensure you stay on your side and do not roll your hips and your body back with the movement.
Lower the knee back down, controlling the resistance.


Phase 3 – advance stage

Body weight squats

Start position is standing straight with the arms out in front and bent at the elbows, the fists should be clenched and the palms facing inwards.
Move downwards into a squat position so that the knees are aligned over the toes and the heels are in contact with the floor, make sure the back is straight.
Keep the head and chest upright and the gaze horizontal.
Hold for 2 seconds and return to the start position.


Lunges

Stand straight with your arms to the side or on your hips.
Take a large step forwards on your affected leg, then drop your hips directly down between both feet, bending your hips and knees to a 90 degrees.
Push back up to the starting position, and repeat.
Make sure you take a large enough step that your front knee does not travel over your foot, and ensure your knee travels directly forwards.
Keep your body up straight throughout the movement.


Crab walks

Place a band around your ankles and gather some tension.
Side-step keeping constant tension on the band.
Make sure you do not bring your feet too close together and keep your toes and knees pointing forwards.


Phase 4 – return to activities

Stretching

Do you always need to stretch the muscle? The answer is NO. While stretching is an important tool to improve muscle elasticity. You may not always need to stretch a muscle if it is NOT tight. Thus, stretching is recommended to be limited to areas you feel are TIGHT when you perform a given movement. Check the affected side and unaffected side – don’t need to stretch a muscle that doesn’t need to be stretched.

Seated piriformis stretch 

Start in a seated position.
Cross the symptomatic leg your ankle is resting on, to the opposite knee.
Apply gentle pressure to the knee as you lean forward, increasing the depth of the stretch.
Hold this position, you should feel a comfortable tension with no pain.


Pigeon stretch

 

Start on your hands and knees.
Cross the symptomatic leg underneath you, then lower your hips down to the ground.
Rest your body forwards on your arms.
You should feel a stretch across the buttock.

 

 

 

 

 

 

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.
