PS Sim Finishes 200 Miles Race

Picture from PS Sim

Yes, you read correctly, PS Sim is the first and only finisher (male or female) so far in the 2021 Singapore 200 Miles Ultramarathon held from 6-9 August by Running Guild. She finished in an amazing 76 hours and 41 minutes!!

She came to see me last Thursday (5/8/21) for one last tune up as she had some knee pain. After treating her, she asked if I could do some taping for her. Since the cause of her knee pain was coming from her hip, I taped her left hip (instead of her left knee) and she was pain free through out the run. Have a look at the whatsapp message she sent me yesterday below.


She even offered to write me a testimonial for the Kinesio taping that I did for her. For all the naysayers who do not believe  that Kinesio taping works, the proof is in the pudding - or rather in PS Sim's legs! 

Now, I have nothing against all the published articles that say Kinesio taping does not work. And there are many healthcare professionals who do not believe in it. However, if the researchers have never learnt to do the actual Kinesio taping correctly, or used different brands/ types of tape, then I would humbly suggest that their research methodology may be flawed. 

Similarly, if I never learnt for example, Alexander technique, and I try it on my patients and end up with poor results, surely it is then unfair for me to say it does not work.

Anyway this post is not about Kinesio taping, this post is to congratulate PS Sim on a run super well done on Singapore's 56th National day! 

She has next set her sights on completing the last mountain she needs to summit before she scales the highest peaks on all 7 continents in Antarctica this coming December. After Team Singapore's outing at the recent Tokyo Olympics, there were calls for the private sector to step up and support sports in Singapore. We have always done that and we will continue to do so. Sports Solutions will be wishing her all the best and supporting her.

No Need To Stretch Or Foam Roll Your ITB?

You are a runner and you haven't been able to run more than 2 km before a sharp pain in your outer knee reduces your run to a hobble. Resting, icing and changing your running shoes made no difference. The sports doctor you saw just diagnosed you with the dreaded Iliotibial Band Syndrome (ITBS). He tells you that you need to stretch your Iliotibial band (ITB) and use a foam roller.

Sounds familiar? Well, this latest published paper on the ITB by Paul Giesler (2020) challenges common treatment approaches of stretching and massaging the ITB. Basically, he says that you do not want to stretch or foam roll your ITB.

Attachments of ITB at L knee
I've written about the ITB before in a few different posts. Except for Daniel Liberman and Carolyn Eng's study, most other articles seem to suggest that the ITB causes pain via a 'friction syndrome'. This is thought to be due to the ITB rubbing to and fro over Gerdy's tubercle on the outer shin bone while running due to hip weakness. 

Treatment is normally targeted at stretching the ITB (to reduce friction). Doctors will often suggest a steroid injection to reduce 'inflammation' (in the bursa) on the outer knee.  Giesler (2020) however,  suggested that ITB pathology is more likely to involve compression of sensitive structures beneath the ITB rather than friction.

also know as Iliotibial tract (ITT)
Since the ITB is a really broad, strong and complex structure with many attachments (picture above) along the hip, thigh and around the knee, it can provide stability for both the hip and knee. Like I wrote before, the ITB is actually thought to function like our Achilles tendon. To store and release energy like a spring. Therefore you cannot and would not want to stretch a spring. A coiled spring can release energy much better than a spring that is stretched out.

From Carolyn Eng's running simulation 
Hence the need to treat the cause of the problem rather than just treating the pain over the outer knee. Hip strength and control thus thought to be key in causing ITBS, especially weakness in hip increased hip adduction (dropping of the hip inwards) during loading. 

Runner on L has increased hip adduction
In runners/ patients with excessive hip adduction while running, progressive rehab and addressing potential causes should be adapted for individual runners, especially while running downhill and during longer runs. I've written on this topic specifically, you can read that article here.

So treatment should be to calm the symptoms (knee pain) and treat the cause. We don't get you to stretch your ITB or use the foam roller in our clinics, come see us if you want to run pain free.

Is Your Running Style Causing Your Running Injury?

How's my running gait?
I saw a patient yesterday who was training for the upcoming Singapore marathon. He started having knee and heel pain after doing a long run of 22 km over the weekend. Upon assessment, he definitely demonstrated a greater contralateral (or opposite) pelvic drop (CPD), indicating Gluteus Medius muscle weakness.
Picture A- Injured runner with CPD and right hip adduction 
Last week we discussed whether doing clam shell exercises was still relevant for someone with Gluteus Medius muscle weakness. Turn's out that this week's post is related to that.

The referenced study (Bramah et al, 2018) investigated and identified certain faulty running gait patterns that contribute to running injuries. In all, 108 runners were studied, including 72 injured runners and 36 healthy runners in the control group matched for age, height and weight.

None of the injured runners received any prior treatment for their injury. Those with an increase with more than 30 percent in training volume were also excluded from the study. The control group of runners ran at least 30 miles (or 48 km) a week.

The injuries the injured runners had were patella femoral pain (PFP), Iliotibial Band Syndrome (ITBS), Medial Tibial Stress Syndrome (MTSS or shin splints) and Achilles Tendinopathy (AT). The injuries were selected as they are most prevalent among runners.

All the injured runners showed a greater contralateral (or opposite) pelvic drop (CPD), demonstrating Gluteus Medius muscle weakness. They had a more extended knee and dorsiflexed ankle (heel striking) at initial contact and a forward trunk lean at the midstance phase of running. These patterns were consistent across each of the four injured groups.
Contralateral pelvic drop
CPD was found to be the most important variable predicting whether the study participants were healthy or injured. For every 1 degree increase in pelvic drop, there was a 80 percent increase in the odds of getting injured.
Injured runner (L) heel striking, forward trunk lean vs normal
Those who had more knee extension makes the patella (kneecap) more vulnerable to lateral tilting and displacement. This may affect knee joint contact areas and increase stress when the foot strikes the ground. If a runner heel strikes with the knee extended, their center of mass is further away from their foot. This leads to an increase in knee joint loading and a increase "braking" forces (imagine applying brakes on while you're running).

Those with a forward trunk lean may have weakness around the back and gluteal muscles as shown by previous studies. The injured runners with PFP and ITB problems had more hip adduction than other runners. More female runners were also found to more hip adduction compared to male runners.

So make sure your Gluteus Medius muscles are strong enough so that you will be less likely to have a running injury.

Ladies, Your Knee Pain May Be Coming From Your Hips


How many of you ladies have knee pain? Well, you may be interested in this then. I have seen quite a few women runners/ triathletes the last couple of weeks, both elite and recreational with knee pain in the clinic. And guess what? Majority of my patients knee pain came as a result of weakness in the hips. Yes, some of them do have contributing factors coming from the knee itself, but the main cause was the hip weakness. So the hip weakness basically led to knee pain.

Well, you do know that at Physio and Sports Solutions we are really good at treating the cause of your pain rather than just treating the pain itself. So besides treating the patients' knee pain, the main thing was to explain the rationale of the treatment plan to them and then teach them how to specifically strengthen the hip muscles.

The strange thing is I've actually noticed this trend quite a while earlier from treating previous patients. So I was really pleased to find an article that was published earlier this year that confirms what I thought.

The study had 19 female runners with knee pain and a separate control group of another 19 female runners as well without knee pain. The group of women with knee pain had greater average hip internal rotation range and reduced hip muscle strength compared to the other group.

The authors concluded that it is the abnormal hip mechanics and decrease strength levels rather than the difference in hip shape and structure of women (as compared to men) that caused their knee pain.

So ladies, if your knees are causing you grief while running, please come in and see us and we will treat the cause of it to prevent it from coming back. And then you can run, pain free of course.
