RSI

Tuesday, June 30th, 2009

RSI stands for Repetitive Strain Injury and relates to a range of injuries to the body that result from repetitive overuse.  In relation to the wrist and forearm the term RSI usually relates to tendonitis (inflammation of a tendon).   A tendon is a tough cord like connective tissue that connects muscle to bone.  The term tenosynovitis is defined as inflammation of a tendon sheath.  The tendon sheath secretes a lubricating liquid called synovial fluid that helps the tendon glide within it.  The two conditions often occur together.  Overuse due to lots of writing (writer’s cramp), typing, assembly line work, etc, can trigger inflammation.

Symptoms

  • Pain
  • Swelling
  • Tenderness
  • Possibly warmth of skin and stiffness at wrist

What you can do

  • Rest is the primary form of management.  The use of wrist splints and braces can be useful in reducing the strain on the tendons of the wrist.
  • Ice therapy
  • Elevation of wrist to reduce inflammation
  • Anti-inflammatory medication as directed by pharmacist/doctor

What we can do

  • Massage to reduce muscular tension in affected muscles
  • Prescription of stretching and strengthening exercises for wrist muscles to improve efficiency of movement and therefore reduce stress on affected muscles

Patella Maltracking

Tuesday, June 30th, 2009

The patella (kneecap) sits in a groove formed by the femur and tibia.  Normally as the knee bends and straightens the patella glides straight up and down within the groove.  If there is an imbalance in the sideways forces acting on the patella the patella tends to get pulled laterally (outwards) as it moves up in the groove thus causing excess abrasion on the hyaline cartilage (smooth low friction covering) on the underside of the knee.  This ‘maltracking’ results in knee pain.  Maltracking can also be caused by poor alignment of the knee i.e.

  • Genu valgum (knock knees)
  • Large Q angle – associated with wide hips and therefore maltracking more common amongst women
  • Pronating or flat feet

Affected groups

  • Participation in lots of sport – especially high impact sports
  • Adolescent females (large Q angle) and softer patella
  • Small or and protruding patella
  • Recent injury.  The muscle on the antero-medial thigh (front-inside) is called the vastus medialis oblique (VMO).  It plays an important role in pulling the knee cap medially (inwards) as the knee straightens.  This muscle wastes away very quickly with inactivity and therefore can adversely affect the tracking of the knee.
  • Dislocation of patella in past

Symptoms

  • Aching pain at the front of the knee beneath the patella.
  • Pain along the inside border of the knee.
  • Swelling – especially after activity
  • Clicking on moving knee (crepitus)
  • Pain aggravated by using stairs especially descending stairs
  • Pain aggravated by sustained periods of sitting

What you can do

  • RICE (rest, ice, compression, elevation) to reduce swelling
  • Stretch ITB (iliotibial band) and muscles on lateral (outside) aspect of thigh

What we can do

  • Rebalance myofascial (muscle and tendon) forces acting directly on patella by reducing tension in ITB
  • Prescribing exercises to strengthen VMO
  • Improve alignment of knee by
  • Prescribing orthotics and reducing over-pronation in feet
  • Reducing Q angle of knee where this is due to weakness in the abductors and lateral rotators of the hip

Rotator Cuff Injury

Tuesday, June 30th, 2009

The rotator cuff is a group of muscles that run from the shoulder blade and attach to the head of the humerus (near end of upper arm bone).  They function to rotate the shoulder and form a cuff or sleeve of muscle around the shoulder joint.  This sleeve of muscle helps stabilise the shoulder which has a very shallow socket to allow for a high level of mobility.  The rotator cuff are also important for controlling the position and movement of the head of the humerus.  The muscles include:

  • Supraspinatus
  • Infraspinatus
  • Teres minor
  • Subscapularis

This shoulder problem may develop quickly due to an injury (acute), or it may develop slowly over time due to routine activity that causes a repetitive strain (chronic). Occasionally, a trivial movement e.g. putting on a coat can trigger a rotator cuff injury.  The third variation of rotator cuff pathology is tendinitis.

Rotator Cuff Injury Causes

Chronic tear

  • Found among individuals in occupations or sports involving excessive overhead activity e.g.decorators, tennis players
  • Variations in the shoulder structure leading to narrowing under the outermost edge of the clavicle (collarbone)

Acute tear

  • Sudden forceful raising of the arm against resistance e.g. in an attempt to cushion a fall on the shoulder
  • Injury often associated with a significant degree of force in individuals younger under 30 years

Tendinitis

  • Degeneration of the muscles as individual gets older
  • Repetitive overuse of the muscles due to everyday activities

Rotator Cuff Injury Symptoms

Chronic tear

  • More common on an individuals dominant arm
  • More commonly found among individuals older than 40 years – especially men
  • Pain normally worse at night and may affect sleep
  • Gradually increasing pain levels with an associated weakness
  • Decreasing ability to move the arm, especially abduction (raising out to side) – therefore difficulty performing activities at or above shoulder level.

Acute tear

  • Sudden sensation of tearing followed by severe pain spreading through the arm
  • Movement limited by pain and muscular spasm
  • Acute pain due to bleeding and protective muscle spasm that usually subsides within in a few days
  • Specific area of tenderness at the site of rupture
  • With significant tears, individual unable abduct arm (raise the arm out to the side) without help

Tendinitis

  • More common in 35-50 age group – especially women
  • Pain felt as a deep ache in the shoulder
  • Tenderness over specific areas
  • Pain develops gradually and aggravated by lifting the arm to the side or turning it inward
  • May develop into to a chronic tear

What you can do

  • Rest the injured shoulder
  • Apply ice therapy
  • Apply heat therapy after 2-3 days of applying ice.
  • Take an anti-inflammatory medication such as ibuprofen or naproxen sodium to decrease the pain and swelling.  You must speak to your pharmacist or doctor first to ensure that the medication is suitable for you.

Treatment

Chronic tear

  • Prescription of exercises to increase range-of-motion
  • Referral for steroids injection or surgery is some cases

Acute tear

  • Rest the arm by supporting the arm in a sling.
  • Referral for imaging may be needed to determine the extent and muscle tear.
  • Early surgical intervention (within three weeks) to repair the tendon maybe required if the injury is severe.  Indications for surgical treatment:-
    • Individuals under 60 years of age
    • Failure to improve after six weeks of conservative treatment
    • If individual is in an occupation requiring constant shoulder use

Tendinitis

  • Rest shoulder in a sling for short periods.  Extensive use of the sling can lead to stiffness, weakness, and reduced range of motion.
  • Progress to contrast bathing as symptoms improve
  • Prescription of exercises to increase range of motion of shoulder without placing stress on damaged muscles
  • Massage therapy to reduce muscular tension in muscles of shoulder
  • Stretches and joint articulation to improve range of motion
  • Referral for steroid injection if symptoms do not resolve.

Back care by activity

Monday, June 22nd, 2009

Standing

  • Basic Position – you should stand upright with your shoulders, hip and ankle in alignment.  You can imagine that you are being lifted by a string attached to the top of your head
  • Surface Height – if you are working standing up then the surface at which you are working should be at elbow height.  If the surface is too low consider sitting on a high stool with good back support.
  • Alignment – if working at a surface remain square on to it and avoid twisting around for a sustained period.
  • Don’t overreach – keep any items you use frequently within easy reach.  When possible move your feet towards an object to be picked up rather than bending forward.

Sitting

  • Alignment – remain upright with the head vertically above the shoulders and hip.  It is important to sit in an upright chair to attain this posture.
  • Good low back support is very important for maintain the upright posture and natural S curve of the back.  If the chair does not have good support you can buy a purpose made product to fit onto the chair or use a pillow or rolled up towel instead which should be placed in the small of the back just above the hips.
  • Depth – your backside should reach the backrest with the back upright.  If not, either change the chair or use a cushion/cushions to fill the space between the back and the backrest finishing with a small cushion to place in the small of the back.
  • Height – your feet should reach the floor with your hips being slightly above your knees.  If your feet do not reach the floor then use a foot rest.
  • Standing up.  Move your backside forwards to the edge of the chair putting one foot slightly in front of the other.  Keep your back straight and stand using you leg muscles and the arm rests if you have them.
  • Change position.  Get up and move around every 20 minutes or so.

Lifting

  • Do you really need to lift?  If possible either use a mechanical aid or push or pull the object instead.
  • Get help if you think the object is too big – don’t overstretch yourself.
  • Alignment.  Keep the spine vertical with the shoulders above the hip and ankle.  The spine is strong in compression and much weaker when we bend over.
  • Technique.  Get your feet as close the object as possible and wide apart to give you a stable base.  Bend at the knees keeping the back vertical when picking up and putting down the object.  Keep the object as close to the body as possible.
  • Never bend your back and rotate when lifting as this causes the maximum strain on the back.

Carrying

  • Objects in hands.  When carrying objects in hands e.g. shopping, try to carry an equal weight in each hand to achieve balance.
  • Carrying on the back. Ideally use a rucksack with a strap on each shoulder.  Load the heaviest items at the bottom on the bag.  If using a shoulder bag be sure to switch on side to the other on a regular basis (every few minutes).
  • Holding and carrying.  Keep the object close to the body with the heaviest side next to the body e.g. if carrying a monitor/tv keep the screen next to the body.  Make sure that the load is stable and the contents cannot slide around.
  • Ready to drop? If you feel that you are going to drop heavy object and it is getting away from let go as bending forward or and sudden muscle contraction can cause injury.

Pushing/Pulling.

  • Chose to push rather than pull an object if possible as this puts less strain on the back.  You can use your legs to provide the force more effectively when pushing.
  • Get help or use a mechanical aid if you think the object is too big.
  • Alignment.  Keep your shoulders in line with your hip and ankles.
  • Grip object at elbow height
  • Beware sudden changes in resistance.
  • Plan for stopping your movement gradually.

Back Anatomy

Monday, June 22nd, 2009

Your spine consists of 24 bones called vertebrae that sit one on top of the other to form a column.  The spine is divided into 7 cervical vertebra (in the neck), 12 thoracic vertebrae in the chest and 5 lumbar vertebrae at the base of the back.  The spine sits on a wedged shaped bone called the sacrum, that in turn rests within your pelvic bones.  Sandwiched between each of your vertebrae are discs.  These discs attach firmly to the vertebrae and consist of rings of fibrous tissue that surround a jelly like core.  The discs allow movement between the individual vertebrae and also act as shock absorbers.

The spine forms a protective channel for the spinal cord, which runs from the brain into a canal running between the vertebrae.  Pairs of nerves branch of from the spinal cord and emerge between small gaps between individual vertebrae.  These nerves carry the signals that control of the functions of the body.

The individual vertebrae consist of:

  • A body at the front which carries our bodyweight and attaches to the discs.
  • An arch that contains the spinal cord
  • Bony projections at the back which allow for the attachment of muscles, tendons and ligaments.
  • Small guide rail joints between the adjacent vertebrae (also at the back) which help control movement.
  • Ligaments hold the vertebrae and discs firmly together in a column. Muscles attach to the vertebrae via tendons. Muscles contract and pull on the vertebrae to maintain posture and create movement.

Basic back care

Monday, June 22nd, 2009

The following section contains information both for people who are experiencing back pain and individuals who wish to use their bodies more efficiently to prevent back pain.

Maintain your backs natural shape.

The cornerstone of back care is to maintain the natural shape of the spine.  If you look at the back from the side it has an ‘S’ shape with a hollow in the small of the back and in the neck.  The middle back curves outwards in the opposite direction.  Try to keep these curves in everything you do and you will minimise the strain you place upon your back.

Keep Active

Don’t rest in bed if your back is painful.  Gentle activity performed with the correct posture will not damage the back and will aid recovery.   Getting fit helps to develop your back muscles.

Vary your activities

Don’t perform the same activity for sustained periods if possible – especially maintaining a fixed posture or anything that causes you pain.    Vary your tasks and if you are suffering from back pain take regular breaks and experiment with your task loading i.e. the amount of time you can perform an activity before you start to experience pain or discomfort.

Build up your back

It is important to strengthen the muscles of your back and abdomen.  You can combine specific exercises to strengthen your back (pilates and yoga are excellent choices) with general activity to keep fit and healthy.  If you are in pain then walking is a good exercise to begin with.  Make sure you are wearing flat cushioned and supportive footwear.  Swimming is a good choice but avoid excessive use of the breast stroke which places a strain on your neck.  If cycling ensure you sit upright.

Bending Down

Never twist and bend at the same time as this puts a very high strain on your back.

Bruised Heel

Tuesday, June 16th, 2009

The heel bone is covered with a small pad of fat which acts to cushion and protect the bone.  This fat pad is prone to inflammation and swelling amongst individuals who participate in high impact sports (running, dancing and jumping) and individuals who do excessive walking.

What you can do:

  • Rest until the pain has resolved
  • Reduce the stress on the area by using a heel pad or shock absorbing insole

What we can do

  • Give guidance on padding the heel
  • Apply tapping to the foot to reduce impact forces

Plantar Faciitis

Tuesday, June 16th, 2009

Plantar fasciits is a painful condition that is due to inflammation of the plantar fascia.  The plantar fascia is a broad band of tendon that runs from the underside of the heel towards the ball of the foot.  The plantar fascia is connected to the calf muscles, therefore tension in this muscle group can contribute to plantar fasciitis.

Symptoms

  • Pain under the heel usually on the inside aspect of the heel which may radiate towards the ball of the foot
  • Nodules or lumps may be felt around heel and arch of foot
  • Pain is aggravated by weight-bearing (standing, walking, running) and direct pressure
  • Pain aggravated by extending toes (bending up) and dorsiflexion of foot (lifting foot towards shin)
  • Pain is usually worse in the morning easing after a short time

Causes of plantar fasciitis

Plantar fasciitis is caused by repetitive strain of the plantar fascia causing it to thicken and lose its flexibility and strength.  Stress factors include:

  • Occupations that require prolonged standing
  • Sports which involve high impact – running, dancing or jumping
  • Anterior weight bearing posture – standing leaning forward with bodyweight distributed over balls of feet
  • Over pronation of the feet (feet rolling in or flattening)
  • Tight calf muscles
  • Stiffness in the joints of the feet which reduces the ability of the feet to act as shock absorbers
  • Unsupportive footwear
  • Excess bodyweight

What you can do

  • Rest as much as possible
  • Try rolling a small plastic bottle full of ice under the foot for up to 5 mins several times per day.  This will both stretch the fascia and reduce inflammation
  • Stretching the calf muscles
  • Stretching the plantar fascia by bending back the toes and pulling the foot towards the shin
  • Wearing supportive cushioned footwear.
  • Wearing foot splint at night to stretch plantar fasica
  • Losing weight
  • Glucosamine sulphate supplements can also be helpful

What we can do

  • Deep tissue massage to stretch the plantar fascia and calf muscles
  • Deep friction to plantar fascia to boost circulation and stimulate healing
  • Improve of foot mechanics
  • Give advice on suitability of orthotics
  • Improve mobility of foot joints to improve shock absorbing properties of foot
  • Assess mechanics of the whole leg with treatment to improve alignment and reduce forces acting on foot
  • Give postural advice
