GENERAL GUIDELINES FOR LOOKING AFTER YOUR BACK



Low back pain is an extremely common complaint, not just with patients presenting to Physio Noosa but in the community as a whole.  Over 85-90% of us will have some degree of back pain at some stage in our lives.  For 90% of people affected, resolution will occur within 3 months.  But this is not the case for nearly 50%, as they will have at least one recurrent episode (Brukner and Khan, 2007)  Back pain is the most common complaint for people under the age of 45 years of age and causes significant loss of time at work and carries huge economic burden.  The cost of low back pain in Australia is over $9billion (Walker, Muller and Grant 2003)               


With this is mind, here are some tips on how to reduce or even prevent episode of back pain.

Limited sustained postures:  Vary positions.  This reduces the static loading that is placed though the spine when a task is either all sitting or all standing and assists in postural muscle activation.  Consider a stand-up desk option for work so sitting times can be reduced and postural variation can occur.

Exercise:  In general, get moving.  Improve and then maintain overall levels of fitness.  Start easy; aim for consistency; develop routine with simple load bearing activity such as walking.  Commence specific Physiotherapist guided exercises to improve spinal range of motion, strength and stability and implement these into your daily exercise routine.  You need to exercise every day for ‘exercise sake’.  Being active each day is important, but doesn’t take the place of exercise.  Remember what you do and how you do it is paramount.  Think about your lifting technique prior to loading (Is my spine straight? is my core engaged? Is the load too heavy? Do I need assistance?)
 
Posture:  Ensure ideal postural positions when sitting, standing and moving.  Make sure your posture is ideal prior to any lifting, carrying, pushing or pulling activities; no matter how light the task may seem.  Ideal posture will reduce the load and the mechanical forces acting throughout the spine and therefore prevent injuries. 



Improve overall health:  Do an honest assessment of your overall health.  With the abundance of information and education available to us in this digital age, it is easy to know where we are falling behind in areas of nutrition, hydration and general health care.  Make small changes each day to these areas and you’ll notice the difference in your health and wellbeing in no time.  Consider wholefood, plant based nutrition.  Reduce intake of animal products and ensure those consumed are the best quality you can afford.  Stop smoking.  Reduce alcohol intake to levels recommended by www.alcohol.gov.au and increase intake of clean, clear fluids. 


Risk factors to consider according to Bruker and Khan (2007)
Risk Factor
Evidence
Age
Inc risk until age 50, then relative risk decreases in men and increases in women
Gender
Multiparous (more than one pregnancy) women, three times the risk
Obesity
Unclear
Height
Unclear
Posture
No association with lordosis or leg length discrepancy
Smoking
Strong association with low back pain and sciatica
Physical Work
Inc risk in those whose work involves bending, twisting or heavy physical labour. 
Inc risk of low back pain and sciatica with exposure to vibration
Coal miners have fewer disc protrusions than other occupations
Low risk of low back pain in farmers
Sedentary Occupations
Inc risk when seated
Driving a car may cause LBP or disc herniation
Jobs involving all standing or all sitting show higher incidence of LBP than those with changing positions
Increased Fitness
Some evidence that good isometric endurance of back muscles may be associated with reduced LBP
Psychological Factors
Stress, anxiety, depression associated with work related LBP


Remember, if you are experiencing spinal pain or have concerns relating to any of the above, visit us at Physio Noosa where our team will provide specific assessment, directed treatment and an individualised exercise program to suit your needs.

WHAT HAPPENS IN AN ACUTE LIGAMENT SPRAIN AND HOW CAN I MANAGE IT?

In our Physiotherapy practice (www.physionoosa.com.au) we get asked many questions, but this is one that has been at the top of the list this week; perhaps because training and competing for many sports is well under way and the inevitable injuries result.  So, one our Physiotherapists, Ross Drummond has penned some thoughts on ligament sprains.


When we expose our joints to extreme force beyond which our muscular and neurological systems can handle, increased tension and stretch to a ligament can cause it to tear or rupture.  The following grades of ligament sprains are:


Image from Brukner and Khan, Clinical Sports Medicine
2007
Grade 1 - mild:  stretched fibres, some micro tears, normal joint integrity and movement
Grade 2 - stretching and resultant tears to many fibres of the ligament with joint and ligament laxity present but a defined end-point noted on testing
Grade 3 - complete tear of the ligament with excessive joint laxity with no defined end -point noted on testing  (Brukner and Khan 2007)

Once the injury occurs the area will go through the following phases of inflammation called the 'inflammatory cascade'.  This ensures the ligament heals in the best was possible and will typically display the following 5 cardinal signs of inflammation:
1. Rubor (redness)
2. Calor (heat)
3. Tumor (swelling)
4. Dolor (pain)
5. Functiolaesa (Loss of function)

Inflammatory Phase:
This phase commences following the acute trauma to the ligament and can typically last anywhere between 3-5 days.  When the tissue cells become damaged they stimulate the release of  various chemicals and inflammatory mediators that initiate the inflammatory response.  These chemicals include prostaglandin, bradykinins and histamine.  They work together to increase blood flow to the site of injury through vasodilation and increased permeability of the tissues.  These chemicals elicit a pain response and pressure from the swelling onto local nerves increases the pain we feel.  The main objective of inflammation is to target and eradicate the irritant and repair the damaged tissues.   Rehabilitation in the early phases (initial 24hrs) of injury can greatly improve recovery. This consists of protecting the injured area to be protected from further damage by immobilisation and minimal weight bearing of the injured joint, rest from activities that will involve the injured body part and by using ice, compression and elevation (RICE).


Brukner and Khan flow chart 

Repair Phase:
The second phase of inflammation is mediated by blood clotting over the damaged tissue cells.  At this time, blood platelets form a mesh to initiate healing.  Within the blood clotting mechanism, fibroblast cells commence the lay down of immature collagen tissue which typically occurs between 3 and 21 days post injury or trauma.  During this stage of healing, electrotherapy such as ultrasound has been shown to encourage fibroblast activity which encourages a structurally stronger ligament.  Physio guided rehabilitation assists in facilitating better alignment of collagen and elastin fibres thereby reducing adhesions and scarring.

Remodelling Phase:
This phase follows the repair phase and can last for up to a year depending on the severity of the damage.  This phase involves the maturation land realignment of collagen tissue fibres.  When first laid down, collagen tissue is disorganised and therefore doesn't possess a great amount of tensile strength.  Through the gradual introduction of controlled strain in the ligament's plane of motion, the ligament gradually strengthens and realigns fibres in a longitudinal manner.  This controlled strain can be facilitated through controlled exercises that progress to functional activity,  Physiotherapist directed exercise programs will safely assist the final process of remodelling and aid recovery.  The risk for re-injury during this phase can be reduced by providing additional support to the joint and ligament with strapping, strength training of muscles in surrounding areas and performing proprioceptive exercises to improve joint positioning sense.

Remember, Physiotherapy guidance is important to facilitate healing and obtain full movement capacity and there is only a very short window of recovery.  If you delay treatment for your injury now then you may prolong time off training, reduce competition ability and performance and increase your chance of re-injury.

HOW BEST TO OPTIMISE YOUR TRAINING

Well, it has been a long time between posts and something I plan on rectifying.  Someone once said to me that we all make time for the things we want to do!

A question I get asked a lot in clinical practice is “How do I get the best out of my training in order to achieve my goals?” or words to that effect.  So I thought I would attempt to shed some light on the topic of “training optimisation” especially given the endurance trail running season is upon us.  So I have penned some thoughts with long distance trail running in mind, however the principles can be applied to other distance and other sports.  Here are some variables to take into consideration.

DISTANCE
www.nutrs.com.au  best running group around!
How long is the event and how should I go about preparing for it?  A general rule of thumb is to aim to cover the distance of the event in one week’s worth of training.  Ie:  100km race; reach 100km of training the week approximately 3-4weeks out from race day.  Periodisation of training needs to implemented in order to gradually build to these levels without succumbing to injury or illness.  For example:  use 4 week cycles to build up distance and time on your feet progressively over 3 weeks, followed by a recovery week similar in distance/time to the initial 1st or 2nd week of that macro cycle.  Start conservatively, build gradually and hasten slowly. 

TIME ON FEET
How long will the event take me to complete?  Aim to spend up to 50% of this time on your feet in training in one session at a pace slower than what you will be competing at.  This allows for hydration and nutrition plans to be tried and tested, develops mental toughness and preparedness and allows for the musculoskeletal system to harden and adapt to training.  This needs to be at sub-threshold levels….long, slow and steady conversational pace.  This pace is important so that the system isn’t stressed or over-reached.  Allow time for recovery before the next session and ensure that the next training session isn't hard or fast.  

PACE
Take the time to enjoy and breathe!
Ensure that your training program adequately trains the aerobic system.  This can’t be stressed enough.  This is the foundation upon which the all physiological systems of the body depend upon for long distance events.  Long, slow, sub-threshold training should be the cornerstone of your training.  Once a solid grounded base has been achieved over at least 8 weeks (at least 2 macro-cycles) only then should specific higher heart-rate sessions be included and only then for sessions strategically positioned into the training program.  This allows for adequate time to recover from harder sessions and prevent any injuries.

TERRAIN
Local Noosa Trails

What type of surface/terrain will I be running on? Technical single track, wide fire trail, mountain goat ascents/descents, road, stairs.   Attempt to mimic this in training as much as possible in order to prepare the legs for what will be required.  If a large portion of the course is technical, then this requires a specific skill set that needs to be trained prior to event day.

TOTAL ASCENT/DESCENT
Mt Solitary in the Blue Mountains is a popular training ground 

If your event has 4000m of ascent gain over 100km, then training needs to simulate this; e.g: broken down into 400m+ of ascent over 10km.  Practice different methods of ascent to mimic your climbing of these ascents during your race.  How you ascend and desend early on will vary later on in an event when you are tired and fatigued.  This is particularly important for ultra-events where power-hiking steep uphills will be required and often this is something we often don’t practice enough in training.



ENVIRONMENTAL CONDITIONS
Aim to train in environmental conditions similar to race day.  Often this is not possible when travelling interstate/internationally, so aim for training in the coolest/warmest parts of the day to simulate your race environment.  Be prepared with your hydration, nutrition and electrolyte needs ahead of time.  Also plan to arrive in your race destination with plenty of time to acclimatise.  A general rule of thumb for events at elevation is to allow at least 1 day for every 1000ft of elevation above sea level.  Expose yourself to the elements on arrival in your race destination and allow the body to adjust.  You need to get out and move in the new environmental conditions and not just sit at the nearest cafĂ©!  This assists with acclimatization physiologically but also allows you to test the adequacy of any gear specifically required for an event in a unique environment.

RECOVERY
“One can not underestimate the power of rest”. This probably deserves blog of its own.  Recovery should be the cornerstone of every training program.  Physiological changes and adaptations to training can only occur when the body is allowed to rest.  Recovery and rest can take different forms and there is a large body of evidence to support active recovery such as: light aerobic activity different to that usually trained.  Recovery also is largely influenced by nutrition and hydration strategies, musculoskeletal strategies (physiotherapy, massage, acupuncture etc) and sleep! Finding the right combination for you is as much and art as it is science.


So, there are some areas to consider when planning your training program for your upcoming event.  

Enjoy those trails, enjoy your training and remember "Mistakes are proof you are trying" Anon
