Soft tissue therapy for complex pain syndromes
Most of my time with patients is spent one-on-one using manual therapy techniques and education. I try to support and amplify any positive results I get from manual therapy through the judicious application of strength and conditioning protocols. I use these principles to rehabilitate and improve the performance of my patients.
Am I different from other health care providers?
I try to be, or at least a little bit better everyday. While, I do the same techniques and treatments as many I just don’t believe in “selling” my treatment to patients with a lot of theories passed off as facts about the body. I question everything I say and continually read and reflect on what I know or think I know. I am probably more obsessed with what I don’t know. You probably won’t hear me tell you that your SI joint is stuck, your pelvis is unlevel, you overpronate, your glutes are inhibited and your myofascia is riddled with adhesions and scar tissue. I am certainly not going to tell you that the wee bit of arthritis you have is causing all your problems. These things occur sometimes but they are often not related to dysfunction. Most disconcerting to me, yet convenient for other therapists, is that these “dysfunctions” also seem to correlate with longer treatment plans. The body is not something that always need correcting…we just need to stimulate it to adapt or modify negative stress on it and it takes of itself.
I think most people can get better with good advice, behaviour modification (e.g if you are a runner we work to identify training variables that might be injuring you), appropriate exercise prescription and some one on one manual therapy.
I tend to question everything so you might hear me often say that the things you have been told from other therapists are poppycock. This is not to say that I have the answers I just don’t believe in snowballing my patients with medical jargon and theories that only have a superficial grasp of body mechanics. People’s pain or dysfunction don’t fall into simple categories.
I try to learn a great deal from my patients as I believe they have a lot of insight into their condition.
On a personal note my wife tells me that I am the most serious, non-serious (aka – slow) runner that is out there.
I have an interesting educational combination of physiotherapy, chiropractic and strength and conditioning training. I have spent 2 1/2 years completing a MSc in spine biomechanics, 4 full time years in chiropractic college (spending more than 15 hours per week for four years practicing manual therapy) and seven years working as a researcher in exercise and clinical biomechanics. After working for several years I spent an additional 2 years obtaining a MSc in Physiotherapy (Queen’s)
Awards and Academic Pursuits
I have been in the rehabilitation field for more than 15 years. Following my undergraduate degree in Kinesiology (4 full time University years) I was awarded the Canadian Society for Exercise Physiology Gold Medal for highest academic performance in Kinesiology. This degree allowed me to obtain certification as a Strength and Conditioning Specialist and Certified Fitness Appraiser and I have worked as a Strength and Conditioning coach for Sir Wilfrid University’s Men’s Basketball team and for Queen’s University Women’s Varsity Hockey Team.
My success in university resulted in being awarded a graduate scholarship (NSERC) to Waterloo University to be 1 of only 2 Masters students studying with Dr Stu McGill, a world leader in Spine Biomechanics, exercise prescription and athletic performance.
As a faculty member at the Canadian Memorial Chiropractic College I developed a research program that produced more than 20 publications on exercise biomechanics, golf fitness and the science of manual therapy. I taught more than 25 graduate students in Spine Biomechanics and Research Instrumentation and supervised more than 50 students and 20 undegraduate research theses.
I was subsequently awarded a Researcher of the Year award by the Ontario Chiropractic Association.
While still in private practice I obtained a full time MSc degree in Physiotherapy from Queens University. While other professionals will pursue ongoing education with weekend seminars I have dedicated more than 12 years of full time University education to just start the process of being a qualified and unique health professional. Add two kids into that and you can see it was a busy but very rewarding time.
I have years of experience treating the full spectrum of aches and pains – from internationally ranked marthoners to individuals with chronic pain following a knee replacement. I utilize soft tissue treatment techniques (ART, myofascial release, nerve glides), corrective exercise, biomechanical analyses, manual therapy (both chiropractic and physiotherapy), Contemporary Acupuncture and pain relieving modalities for a comprehensive treatment strategy.
