Benign paroxysmal positional vertigo (BPPV) is one of the most common forms of vertigo, affecting 2% of the population at some point in our lives. 

BPPV is caused by a problem with the inner ear, where a small calcium deposit forms and moves with gravity around the different angled canals of the inner ear. BPPV is “positional” as it is triggered by specific head movements, for example, turning your head to the left with rolling over in bed. Symptoms of vertigo are room spinning, disturbed balance, and nausea.

BPPV typically resolves within a few weeks, but can be recurring.

Your GP can give you anti-nausea medication, and Physiotherapists treat BPPV with a sequence of movements and positions, called the Epley Manoeuvre, that uses gravity to re-position the calcium crystals.

FOOTBALL RECOVERY STRATEGIES 
(Grégory Dupont, Mathieu Nédélec, Alan McCall, Serge Berthoin and Nicola A. Maffiuletti, 2015)

• High intensity exercise leads to fatigue.  
  
• Fatigue causes a decline in performance.  
  
• A high percentage of injuries occur late in each half of a game, suggesting that fatigue is a risk factor for injury.

• Combination of central and peripheral factors.
  
• Central fatigue = decreased maximal voluntary muscle contraction and sprinting ability.
  
• Peripheral fatigue = muscle soreness, damage, and inflammation.
  
• Depletion of glycogen stores.
  
• Dehydration.
  
• Muscle damage / stiffness / swelling.
  
• Mental fatigue / motivation.
  
• Jet lag / disrupted body clock / stress / poor sleep.

• Immediately after a match, 20M sprint time, quadriceps strength, and vertical jump height are decreased by about 10%.  
  
• Full recovery can take between two and four days.  
  
• Injury rates are increased when there are less than 6 days between matches.

"When playing two matches per week, the 3-day recovery time between two successive matches may consequently be insufficient to fully recover."

Immediately after a match, players should drink a large volume of fluid (about 150% of the sweat loss) with a high concentration of sodium (about 500 to 700 mg/L of water), flavoured milk, and tart cherry or berry juice. Then, they should eat a meal containing high-glycaemic index carbohydrate and protein within the hour following play.

Rehydration and consumption of carbohydrates and protein are effective techniques for optimising repair of muscle damage.  The addition of sodium at 500-700mg/L promotes fluid retention, stimulates thirst, delays urine production, and increases glucose absorption.  It is recommended to drink a large volume of fluid after the match instead of small quantities gradually.

It is recommended to take 1.2g of carbohydrate per kilogram of bodyweight per hour for up to 5 hours after a match to enable maximum re-synthesis of muscle glycogen stores.

20g of milk protein during the first 2 hours of post-exercise recovery stimulates muscle protein synthesis.  Flavoured milk is an effective beverage for post-exercise recovery. It contains carbohydrate and proteins in similar amounts to those used in studies demonstrating improved post-exercise recovery.

Juices such as tart cherry juice, tomato juice, or berry juice are also recommended to enhancing the recovery process. These juices are loaded with a high antioxidant capacity, which reduce oxidative stress and inflammation.

Alcohol delays recovery as it is a diuretic, increases urine output, impairs sleep, delays the muscular recovery process, and decreases maximal strength.

• Sleep is an essential part of recovery management.
  
• Lost sleep reduces endurance performance, maximal strength, cognitive performance, and the immune system.  
  
• Less than 7 hours sleep per night triples the risk of infections and double the risk of musculoskeletal injuries.
  

• Several meta-analyses confirm the benefits of cold-water immersion for recovery.
  
• The recommended regime of cold-water immersion is: whole-body immersion lasting 10 to 20 minutes at a temperature of 12 to 15°C immediately after the match.
  

• Active recovery performed after a match does not present any benefit for physical performance.
  

• Most studies fail to find a significant beneficial effect of massage for recovery.
  
• Psychological benefits: decreased subjective symptoms of soreness / improved perceptions of recovery.
  

• There is no substantial scientific evidence to support the use of stretching to enhance post-exercise recovery.
  
• Stretching is not clinically worthwhile in reducing muscle soreness in the days following exercise. 
  
• Recovery of physical performance is not improved after stretching.
  

• Meta-analysis on the effects of compression garments on recovery following damaging exercise indicated that the use of compression garments had a moderate effect on recovery of muscle strength, muscle power, creatine kinase and in reducing the severity of delayed onset muscle soreness.  
  
• A placebo effect due to wearing the garments could not be excluded.
  

1. The first step is hydration; the mass of the players should be measured and compared to the pre-match body mass in order to propose the appropriate quantity of fluid to drink (150% of body mass lost). The fluid should contain a combination of water and a large amount of sodium (500 to 700 mg/L of water).
   
2. The second step consists in drinking a tart cherry juice and chocolate milk in order to restore glycogen, to reduce oxidative stress and inflammation, to stimulate muscle repair and to promote quality and quantity of sleep.
   
3. The third step is the cold bath. The players should immerse themselves up to the neck at a temperature between 12 and 15°C for 10 to 20 minutes to accelerate the recovery process.
   
4. The fourth step is to wear a compression garment until bedtime.
   
5. The fifth step is to eat a meal high in carbohydrate with a high-glycaemic index and protein within 1 hour after the match (for example soup, well-cooked white pasta or mashed potatoes, chicken or fish, yogurts or cake).
   
6. The final step is to have a good night’s sleep.
   

WATCH DR DUPONT'S PRESENTATION AT ASPETAR'S POST-EXERCISE RECOVERY CONFERENCE:

​I’d guess that most people feel guilty about not stretching enough.

Interestingly, health professionals have changed our tune about the importance of stretching.  Research over the last 15 years has suggested static stretching is not as beneficial as was once thought.  I’ve been having conversations about the reasons to stretch (or not) for at least the last 15 years, but the current science on stretching just isn’t catching on.  

So, what do we know?…
​

No.  There is a lot of evidence that stretching does not reduce the risk of injury.  This systematic review and meta-analysis of randomised controlled trials found stretching does not prevent injuries, whether done before or after training.  This randomised controlled trial, and this systematic review concluded stretching before exercising only reduces the risk of injury by less than 1%.  

​Therefore, in practical terms the average athlete would need to stretch for 23 years to prevent one injury.  Definitely not worth it.
​

No.  A systematic review concluded that stretching before or after exercising does not confer protection from muscle soreness (ref).  Stretching was found to reduce muscle soreness by a trivially small amount - less than 2%.

“Most athletes will consider effects of this magnitude too small to make stretching to prevent later muscle soreness worthwhile.”

​No.  Stretching for the amount of time that most people would hold their stretches, does not make any actual difference to flexibility.  The mechanisms of stretching have been extensively studied.  There is moderate evidence from a systematic review that stretching can increase flexibility (ref). However, to achieve an actual improvement in muscle compliance we know the total duration of stretching needs to be at least five minutes per muscle group (ref).  Therefore to stretch hamstrings, quads, and calves, both left and right, as part of a warm up before sport, it should take at least 30 minutes - which is practically impossible as part of a warm up.  We know the one or two, thirty second stretches the majority of athletes would perform during their warm up are just not enough to actually improve their flexibility (ref).
​

What people find most surprising about static stretching is it impairs subsequent performance (ref).

A substantial body of research has shown that sustained static stretching acutely decreases muscle strength and power (ref).  Stretching before an endurance event lowers endurance performance and increases the energy cost of running (ref).  Cycling efficiency and time to exhaustion are reduced after static stretching (ref).

Pretty much any measure of performance is made worse by stretching.  Static stretching impairs: 

• strength
• maximal  voluntary contraction
• isometric force
• isokinetic torque
• one repetition maximum lifts
• power
• vertical jump
• sprint times
• running economy
• agility
• balance

A comprehensive review (ref) from 2011 concludes:

“Based on the majority of the literature, it would seem logical to recommend that prolonged static stretching not be performed prior to a high level or competitive athletic or training performance.”

​Obviously, I’ve been talking about sustained, static stretching.  It has been shown that there is no stretch-induced strength loss with dynamic stretching (ref).  However, the efficacy of dynamic stretching for increasing flexibility is yet to be determined (ref).
​

I do get people to stretch if there’s a specific pathology that needs treating.  And you do need to stretch if you need flexibility to achieve certain positions in your sporting performance (hurdlers / gymnasts / divers, etc).
​

If you’re happy with your stretching routine, keep doing it.  If you think it feels good to stretch after exercise then there’s no harm.  But I definitely wouldn’t recommend stretching at the expense of other techniques that are proven to aid recovery.

I’ve been treating a chap with a sore knee who really wants to have an arthroscope (keyhole surgery). The knee’s been sore for a while. There’s some “degenerative changes” on a scan, including a torn meniscus. There’s a local knee surgeon who’s really good and is a friend of his. He thinks it’s a no-brainer. He needs an arthroscope. It a quick and easy solution to his problem that has worked well for him and his friends previously. It’s time to have “a bit of a tidy up”.
​

This is a very common presentation, and having an arthroscopic debridement is a very popular decision. 75,000 knee arthroscopies are performed in Australia each year. Therefore, you would imagine there is good evidence to support having one. Unfortunately it depends on who you speak to…

A change has been in the air since a 2002 randomised controlled study allocated 180 patients with osteoarthritis to either an arthroscopic “tidy up”, or sham surgery (where the patient was given an anaesthetic, incisions were made, but no actual “tidying up” was done) and the study concluded there was no meaningful difference in pain or function between the groups at follow up.

Since then, a number of studies have compared arthroscopic debridements and partial meniscectomy for degenerative knee injuries with exercise or doing nothing (Herrlin 2007, Kirkley 2008, Katz 2013, Sihvonen 2013, Yim 2013, Kise 2016) and the results have been unanimous.

A recent systematic review summarises: “these findings do not support the practise of arthroscopic surgery for middle aged or older patients with knee pain, with or without signs of osteoarthritis.”  

And another: “A trial of nonoperative management should be the first-line treatment for such patients.” 

Editorials summarise that:

“This high quality evidence dictates that meniscectomy is an ineffective treatment for symptomatic degenerative meniscal tears.”

And that…

“Arthroscopy for degenerative meniscal tears is no longer supported.” (ref)

And

“There is now overwhelming evidence that arthroscopic knee surgery offers little benefit for most patients with knee pain.” (ref)
​​

We do a lot of arthroscopes and people get better. What’s happening?

When you come and see me with degenerative knee pain and I tell you, “you need to do six to twelve weeks of strengthening exercises”, it sounds like hard work. Pffft. Understandably we want an easier option.

“Have surgery” sounds like an easier option. Someone else is doing the work for you. After the surgery, you proceed to do six to twelve weeks of strengthening exercises, but this time you’re happier to do the work because we take surgical post-op instructions seriously.

Twelve weeks later both these two groups are a lot better. Bingo-bango, “surgery” fixed me.

Two million knee arthroscopies a year globally, costing billions of dollars.
​

A pretty typical pathway goes something like:

• Sore knee
• GP says “you’re silly to have played football”, try some pain killers
• Not much better
• GP says “we better get a scan”
• MRI shows “degenerative changes / meniscal tear” which seems like a structural injury
• Who fixes structural injuries?… Surgeons
• Refer to surgeon
• Surgeon wants to help. What can he do? An arthroscope and a “bit of a tidy up”.

​I think we need to be careful at the MRI stage. MRIs are a lot cheaper and easier to get these days so it’s less of a big deal to get one. I was chatting to a mate with a sore knee and his MRI showed some degenerative changes. Rather than being told that it’s normal to see those sorts of things in knees as old as ours, and that it’s not necessarily the thing that’s giving him pain, he was told the knee is “bone on bone”. How can anyone ever expect to recover without surgery with that sort of imagery? Bone on bone seems definitive. Surely the only way to fix “bone on bone” is surgery?

But we know degenerative changes on MRI are poorly associated with symptoms, and degenerative changes are the norm in middle-aged knees (ref). 

Let’s try some strengthening. You will be surprised.
​

The people I do refer to a surgeon for cartilage surgery have suffered an acute twisting injury with mechanical “locking” symptoms (i.e., an inability to fully extend the painful knee because of a meniscus tear lodged between the articular surfaces).

Sydney is in lockdown again from Friday June 25th to Friday July 9th.

During this current lockdown, Fit As A Physio is staying open to continue offering quality care to my clients.

The Department of Health has specifically confirmed that physiotherapy is deemed an essential service. The Health Minister has encouraged private practices to remain open, as it will reduce demand on general practice and the hospitals if patients can still see their physiotherapist for their musculoskeletal and acute care management.

I have completed the Department of Health's "COVID-19 Infection Control Training".  I have reviewed all clinic hygiene practices, to ensure optimal safety and care for every person who attends the clinic.

There are many things I am doing as a registered health professional to minimise risk of exposure, through rigorous hygiene practices, and patient screening, to keep you safe.  

You are welcome to attend your appointment, subject to the following conditions:

• Please do not come to your appointment if you are unwell with any potential COVID symptoms.
• Please do not come to your appointment if you have been advised to quarantine or self-isolate.
• Please sign-in at the front door with the Service NSW QR code.
• Please wear a mask.
• Please use the hand sanitiser at the front desk on entering and leaving.

Thank you for your cooperation with these measures.

For our safety:

• I am leaving space in-between appointments to allow time for cleaning, and to minimise patient interaction in the waiting room.
• I will not be greeting you with hand shakes or other contact hand gestures.
• I am wiping down contact surfaces between appointments with Viraclean Hospital Grade disinfectant.
• I am continuing with my normal hand hygiene measures of thorough hand washing before and after all patient contact.
• ​I have the COVIDSafe app downloaded and open, and encourage you to do the same.

​If you are in self-isolation or would prefer to minimise contact in any way, you may like to consult with me via video. "Telehealth" uses technology that’s readily available on your computer or phone to receive assessment, diagnosis, and rehab prescription. FaceTime, Skype, or PhysiApp are easy options. The standard consultation via telehealth is $39/15mins.

If you would like to talk to me about commencing or continuing your physio through Telehealth, please phone 9969 6925, email fergus@fitasaphysio.com, or book online here.

Stay safe and well.

​Sports and exercise medicine clinicians often refer for diagnostic imaging to help direct clinical management. The use of musculoskeletal MRI has risen rapidly in recent decades, yet the clinical benefit of MRI is uncertain. Imaging is useful for the differential diagnosis of many health conditions, including possible red flags, however, there are growing concerns of potential harm from MRIs caused by clinicians misinterpreting results triggering unnecessary interventions escalating patient fear/distress. Evidence-based reporting and clinically relevant interpretation of MRIs is critical.

Recognising the clinical significance of MRI findings is often a challenge given the substantial discordance that exists between structural pathology and symptoms. Emerging evidence indicates a high prevalence of so-called abnormal findings on MRI in individuals without symptoms. A collation of systematic reviews (and cohort studies when no review available) highlights that typical features of deterioration, such as cartilage lesions, hip and shoulder labral tears and spinal changes (eg, disc degeneration/bulge) exist in many healthy asymptomatic adults (figure 1). Approximately 8 of 10 adults aged ≥40 years have asymptomatic disc degeneration, while almost half of all adults aged ≥40 years have knee cartilage lesions but no pain. Although the prognosis of these asymptomatic findings is not well established, even in cases of further structural deterioration (eg, longitudinal cartilage loss) the association with pain appears minimal.5 These findings are critical for clinicians and patients to understand the relevance of structural pathology and can be used to address recent calls for radiology reports to include age-matched asymptomatic prevalence rates. Such an approach, together with discussion with patients putting MRI findings into context, may help minimise patient anxiety, and beliefs they are damaged and vulnerable, as a result of a diagnostic label. Including such epidemiological information on spinal MRI reports reduced subsequent opioid prescription although had little effect on healthcare utilisation.

The high prevalence of asymptomatic changes on MRI emphasises that such features may not always be the source of pain in symptomatic patients and should not routinely be considered as pathological processes requiring intervention. Instead, in many people they likely represent part of the normal ageing process—like wrinkles on the skin.

Current evidence suggests that it is more common than not to have a cartilage lesion or disc bulge as we age. Perhaps it is time we redefine what a ‘normal’ MRI is and start being ‘CLEAR’ with patients when discussing imaging results—consistent language, including epidemiological information and assessment of relevance.
