Day 2 Of Kinesio Foundations Course

Most of the participants left some of the Kinesio tapes done on Day 1 of the course on them still. We went through how that felt so they can understand how patients feel withe tapes after they go home. Everyone felt that the taping had good results.

We then started Day 2 with the Kinesio Corrective Techniques. The occupational therapists in the class requested for a few scenarios/ topics for the upper arm/ shoulder after a patient had a stroke and we covered that too, even though that was not in the syllabus.

We left more time at the end to do the Jelly fish and the epidermis, dermis and fascia (or EDF) techniques. The participants took the time as those techniques needed lots of focus and concentration.

A big thank you to all the participants, my family and colleagues for helping out. Would not have done it without all of you. Stay tuned for the next course.

Kinesio Foundations Course Day 1

Sports Solutions hosted Day 1 of the Kinesio Foundations Course today. We have occupational therapists, physiotherapists, a medical doctor, a yoga instructor in our class this time.

With Dr Sangita and Sarah
Stay tuned for Day 2 tomorrow where there is a bigger emphasis on the Kinesio Medical Taping section instead of just the Kinesio Taping Methods where muscles, joint and tendons were the main focus. 

Some of the techniques include the Space Correction webcut applications for bruising and swelling. We will also do the EDF (epidermis, dermis and fascia) and jellyfish taping. 

None of the brands of tape has any of those mentioned above.

Tarsal Tunnel Syndrome

Picture from Orthopaedia.com
A patient came in to our clinic declaring she has plantar fascia pain in her right foot. She had seen another physiotherapist a few years ago for plantar fascia pain in her left foot and had gotten better. This time she tried orthotics, lots of stretching and even shockwave (or ESWT) with the same physiotherapist, but there was no improvement.

This is how she described her foot pain. She said there was a burning, aching pain at the bottom of her foot and on the inner heel. She said it almost feels like an electric shock. Her pain gets a lot worse after prolonged standing and sometimes wakes her up at night. She also gets numbness in her toes. 

None of those symptoms sound like plantar fascia pain to me. Patients with plantar fasciitis usually have pain during the first few steps when they get out of bed in the morning. There is rarely numbness, burning or electric shock sensations in the toes.

Upon assessment, there was no pain on the posterior calcaneal tubercle (where the PF inserts) nor along the plantar fascia itself. 

I elicited her pain when I did a modified Straight Leg Raise test by holding her foot in full dorsiflexion and eversion. However, there was no tingling or zinging in the foot when I tap on the medial malleolus (over the tarsal tunnel) - also known as Tinel's test. Online articles often describe a positive Tinel's test.

I explained my findings to her. My patient actually has Tarsal Tunnel Syndrome. This is when the posterior tibial nerve gets 'trapped' and irritated in the tarsal tunnel at the inner part of the foot (pictured below). 

Picture from Teachmeanatomy
The tarsal tunnel is a space just behind and below the medial malleolus and serves as a passageway for the posterior tibial artery, nerve and what we call Tom Dick and Harry muscles (tibialis posterior, flexor digitorum longus and flexor hallucis longus). The 'roof' of this tunnel is covered by the flexor retinaculum. It is a thick and strong fibrous band that holds Tom, Dick and Harry in place.

Tom, Dick and Harry- back of R leg
Entrapment of the posterior tibial nerve in the tarsal tunnel caused my patient's foot pain, not plantar fasciitis.

Online or AI* searches always say that flat feet or severe overpronation can cause tarsal tunnel pain as it can stretch the nerve although my patient does NOT have flat feet.

My patient did have a severe right ankle sprain a few months ago that caused swelling and perhaps thickening in the connective tissue in the tunnel that eventually caused this. It was also not treated properly, causing her to compensate and stand and walk differently possibly 'tractioning' her posterior tibial nerve.

A ganglion cyst in the canal may also cause this since it reduces the space in the tunnel. I have never come across this though in the 27 years of being a physiotherapist.

When a patient complains of bottom of foot pain, plantar fasciitis is usually the diagnosis one thinks of. The symptoms of tarsal tunnel syndrome pain can be similar to lumbar radiculopathy, diabetic and peripheral neuropathy or plantar fasciitis. Hopefully this article will correct that.

Can Cross Training On A Bike Translate To Better Running Performance?

Picture from Bikatadventures.com
I had shin stress fractures in both legs from running too much when I was 20. The doctor I saw said that I could not run for a minimum of 6 weeks. I could only swim or bike. It was this cross training regime that got me started in triathlon later.

This concept cross training emerged in the 1980s along with the popularity of triathlon. Earlier studies reported that performance in a primary sport can be maintained despite reductions in volume of the primary sport by training in a variety of sports. These findings suggest potential crossover effects between endurance training modalities. Are these findings still relevant?

The following systematic review by Menges et al (2026) compared the effects of running only and cycling only training interventions to evaluate cross training transfer to sport specific VO2 max and running performance.

The authors found 7 studies with intervention durations of at least 4 weeks. These were run only training with cycling only or combined running-cycling interventions. Outcomes included VO2 max assessed on a treadmill or cycle ergometer as well as running time trial performance for 1 mile, 3000m and 5000m.

So does cross training on a bike help running performance? This meta-analysis suggests it does. The subjects who performed run only, bike only or combined running and cycling training performed similarly in the 1 mile, 3000m and 5000m time trials. They also had improved VO2 max values regardless of testing method (treadmill or cycle ergometer).

Cycling engages the quadriceps and gluteus maximus muscles in ways that running does not. When the muscles get stronger, it helps improve running economy and power (especially in hilly races).

Instead of running twice a day, you can take away some of the extra strain on the legs by cycling (or even training on the elliptical machine) without the repetitive impact forces of running. This is especially beneficial during recovery periods or for runners prone to injuries.

Cycling is low impact which is great for your joints. However, it does little to help your bone density. Running on the other hand has impact loading that helps to maintain or even increase bone strength which is great for older athletes.

The findings should be interpreted with some caution since there were limited studies (7) and the fairly short training period.

For shorter distances up to 5 km at least, there may not be any differences but in a longer event like the marathon, you still need to run since the run muscles will not used as much while cycling. Biking can definitely help the aerobic fitness but not the specific leg muscles, and running performance may decline.

Running and cycling can actively enhance each other when integrated carefully. If you're a runner looking to improve your endurance without extra impact or a cyclist looking for stronger stabilizing muscles, cross training helps.

The key is balancing both to meet your specific training goals while avoiding overuse injuries.

The principle of specificity suggests that cross training can offer general fitness benefits, the most significant performances are achieved through sport specific training. Before Sabastian Sawe broke the 2 hour barrier for the marathon, he was running in excess of 200 km a week in the 6 weeks leading up to London, with a maximum of 241 km (150 miles). 

So, runners and cyclists should incorporate cross training as a supplementary activity rather than a replacement for their primary sport.

Carbon Plated Shoes And Stress Fractures

Picture from Prodirectsport
I just saw 3 different people wearing carbon plated shoes at the Cold Storage in Holland Village. They were shopping for groceries and definitely not running. On one hand you have someone like me who's still unwilling to run in carbon plated shoes while on the other hand they are a dime a dozen amongst runners now (and people walking in Cold Storage). Most runners use them in training as well, not just at races. 

No running study has studied whether carbon plated shoes (known as advanced footwear technology or AFT) changes running biomechanics associated with bone stress injuries (BSI), or shin splints. The researchers goals were to measure running biomechanics while running in an AFT shoe.

23 runners (11 women, 12 men) with an average age of 25.4 ± 2.7 years were recruited for the study. They ran randomly in 3 different types of running shoes, neutral, lightweight (responsive foam) and AFT at 3 self selected running speeds. A run at their 'training effort', a tempo run and at 5 km race pace.

Biomechanical variables associated with BSI such as cadence, vertical ground reaction forces, ankle and rearfoot eversion forces were measured during each run and shoe condition.

Results show that with neutral running shoes, ankle plantarflexion moment was higher compared to lightweight foam and AFT. There was less rearfoot eversion movement in the neutral shoe compared to lightweight foam and AFT. 

Cadence was lower while running in AFT shoes  compared to neutral or lightweight foam shoes. This is relevant since a longer running stride has been linked (in earlier studies) to BSI in the lower limbs.

Rearfoot eversion velocity (the speed at which your foot rolls down and inwards), or pronation was higher in the lightweight foam shoe compared with both neutral and AFT shoes. There was no significant difference in this between the neutral and AFT shoe.

The authors concluded that there were increases in several biomechanical variables associated with BSI  while running in AFT shoes. Although these changes were small, they tend to accumulate and can contribute to increased forces on bones in the lower limbs.  

The authors suggest that rotating running shoes and gradually using AFT to adapt to the differences may help reduce potential injury risk while optimizing running performance.

Repeat The Same Training?

I started keeping a handwritten training log (pictured below) after I started running at 13. Back then there were no apps to keep such records for you. I would record how far I ran, time taken, how I felt, what shoes I used, etc. 

I found it useful so I could look back on what training I did when taking part in a similar event. Say my key interval workout for a 1500m track race that I had won previously was 8x200m with 30 seconds rest. I would replicate those sessions along with deciding if I could handle more. Back then, I was a teenager and was able to run personal bests in all my events every year.
I assume that when I responded well to a training program once, I'd respond similarly or better the next time. However, a recent study suggested otherwise.

A group of researchers had subjects do the same 8 week endurance training program twice, but separated by a period of detraining that had to return to baseline. 42 out of the 53 recruited completed the study.

Each 8 week period had 24 supervised 45 minute interval cycling sessions at moderate to maximal intensity. Identical training instructions were applied such that the same training program was repeatedly prescribed to the same individuals. Exercise intensity was individually prescribed relative to performance and adjusted every second week to mainatin a comparable training stimulus across periods.

Results show very poor reproducibility of adaptation. One athlete increased VO2 max by about 600mL min⁻¹ after the first training period. However, there was no improvement at all after the second training period. Yes you read correctly, zero improvement.

Same athlete, same program, but very different outcome. I asked a few coaches whom I treat if this was similar to the athletes they coach. They told me they see it all the time. Training response varies.

The training may be the same but the variations in external factors such as sleep, diet, work stress, travel and illness contributes to the variability in individual training adaptations.

That's what the researchers concluded too. The substantial within-individual fluctuations were largely consistent between training periods and they suggest that this  within-individual fluctuations does not reliably reflect their capacity to adapt to the same training stimulus in the future.

So low stress plus good training leads to adaptation while high stress plus the same training may lead to very different outcomes.

Take away message? Do not assume that because a program worked once, it will work the same way the next time. Monitor the state of your own life stresses and modify accordingly.

Can You Trust AI With Nutritional And Athletic Performance Advice?

Picture from Sixminutemile.com
I was reading about how 2024 Olympic road race cycling winner Kristen Faulkner built her own artificial intelligence (AI) model to analyse 9 years of her own performance data to help her uncover what's missing from women's sports science. It allowed her to have data that helps explain not just what happened but why.

Faulkner said she coded to build the AI technology that can learn from data, spot patterns and make decisions. These are skills that we usually associate with human intelligence. 

AI is already in our everyday lives. We get Google Maps directing our commute, Spotify suggesting songs on your playlist and hit ChatGPT with any question we might have.

Many people use AI for everyday health, exercise and medical queries. Are these AI driven chatbots reliable and accurate? Our patients already use AI to self diagnose their pain and injuries. Some studies show chatbots are largely accurate, while others reported frequent errors and even a risk for transmitting inaccurate information.

The following research investigated 5 popular AI driven chatbots to evaluate their responses to everyday health and medical queries across 5 categories: cancer, vacines, stem cells, nutrition and athletic performance. Both open ended and closed ended questions were used.

Gemini, Meta AI, DeepSeek, ChatGPT and Grok were the 5 chatbots used. They were each presented with 50 prompts across the 5 topics mentioned above. The researchers used an adversarial framework to strain models towards misinformation or contraindicated advice.

An adversarial framework refers to a system, process or analytical model structured around opposition, competition or conflict. This is a cybersecurity approach used to test the vulnerabilities of AI systems.

Responses were then independently rated by 2 domain experts as non-problematic, somewhat problematic or highly problematic. Citations were assessed for authenticity and completeness while readability evaluated using the Flesch Reading Ease score (100 point scale with higher scores being easier to read).

Results showed that nearly half of ALL responses (49.6 percent) were problematic, 30 percent somewhat and 19.6 percent highly problematic. Nutrition and athletic performance topics had the weakest performance and Grok generated significantly more highly problematic responses than expected.

Reference quality was poor across all chatbots. The median completeness score was 40 percent. No chatbot came up with a fully accurate reference list. Misleading, unreliable or fabricated citations were common. So please be careful if you use them.

All the 5 chatbots produced responses that were rated "difficult" on the Flesch Reading Ease scale, equivalent to university-level reading. Chatbots answered consistently with confidence regardless of accuracy, while rarely declined to respond (2 refusals to answer across 250 total responses).

The researchers concluded that continued deployment of AI chatbots without public education and regulatory oversight risk amplifying health misinformation. Especially in the field of nutrition and athletic performance. They also suggested that public education, professional training and regulatory oversight to ensure that generative AI support rather than replace professionals.

My suggestion when searching for health information is to treat these AI chatbots with a good amount of skepticisim and to verify information with qualified professionals or peer-reviewed sources. There will be some benefit seeking ideas and initial information from a chatbot, but beyond that you will need a real human expert.
