Gravity - it's FREE!!!

Running is one of the most common and popular methods of fitness in the world, with many cities and communities taking part in establishment of running events from 5k to marathon level and above, to smaller running cohorts, and for social events. However, while running has a high link to overall improved cardiovascular wellbeing, it is also one of the most injury prone athletic populations in world with injury incidence of up to 80%! Fortunately, there are many strategies to help combat and prevent running related injuries for any skill level. TRAIN APPROPRIATELY! As with any other sport, training for the specific demands of running can greatly reduce the risk of injury. The World Health Organization (WHO) recommends a minimum of 150 minutes of moderate-intensity aerobic physical activity or 75 minutes of vigorous-intensity physical activity throughout the week, based on strong evidence of health benefits and reductions upon mortality rates. While many factors influence risk of injury, there are a few significant ones for any running athlete: Type of exercise Find the aerobic exercise that you are passionate about! However, limiting yourself to the same route and same type of run could increase your risk for injury. Cross training with other modes of exercise including strength training or different types of runs could help reduce risk of chronic and acute injury! Exercise frequency and progression Novice runners may benefit from having more days of recovery, especially in the beginning. However, knowing when to progress overall speed, distance, or number of training days can be tricky! Remembering to increase only one variable at a time can help mitigate risk of injury. Exercise intensity and duration Having trouble with determining how intense your run is? Heart rate is an excellent measure of overall cardiovascular output. An easy calculation for determining your Heart Rate maximum is: 220-age As stated prior, recommended minimums for health benefits are 150-300 minutes of moderate intensity, or 75-150 minutes of vigorous intensity per week that typically are broken up into 3-5 days during the week. However, do not let these recommendations deter you from running if you cannot reach them! Calculate using % of Maximum Heart rate, Moderate intensity for aerobic exercise 60-75% of your calculated Heart Rate max; vigorous intensity 75-90% of maximum Heart Rate Equipment Matters! In a recent systematic review of 15 studies there was moderate to strong evidence of higher injury prevalence with persons who had sustained a previous injury, as well as the use of orthotics and the same pair of running shoes for longer than 4-6 months. While there are many different brands and trends within the running shoe and orthotic industry, it is important to note that finding the right pair of shoes for you may take time! Additionally, according to a study on use of multiple shoes during training, results found that there was a 39% decrease in running related injuries over a 22-week period when athletes used at least one more pair of running shoes during the week. Rehab potential 80% of all running injuries are result of overuse or chronic pathology, which may be a result from overtraining or limited tissue adaptations from the amount of load produced on the body during activity. Different types or locations of injury require methods of individualized rehabilitation, and the therapy experts at Evolution Sports Physiotherapy are well versed in the appropriate rehabilitation and progression of any running related injuries. So, whether you are a seasoned runner looking for a full evaluation of running form, or a beginner working towards your first 5K, our approach towards integration of best available evidence within clinical practice and dedication to patient care provides our patients with optimal rehabilitation potential.

Musculoskeletal Diagnostic Ultrasound (DU) is a powerful tool that can be utilized by Physical Therapists to identify tendonopathies. Furthermore, DU can be utilized with Dry Needling in order to visualize the needle which has been shown to significanlty improve the accuracy of the user to target the affected area compared to relying solely on palpation and anatomical landmarks.

A brief review of the "active" phase in running mechanics

The first installment in our running mechanics series discussed the importance of stability and striking your support leg under your hips. This Pose position will allow the runner to absorb forces more readily and prepare more efficiently for the next movement. The next movement in the Pose Method is the Fall. The purpose of this phase is to increase speed and since the Pose Method is all about “effortless running,” optimal body alignment will allow gravity to do the brunt force of the work.

The Pose Method of running allows one to identify and promote a running form that maximizes gravity along with the body’s effort and stored energy (elasticity) to create efficient movement. In essence, it makes running easier and less physically stressful to the body. There is a lot of debate surrounding running form. Some even question if it’s necessary to promote a particular way of running. However, it is a universally accepted foundation that every activity has a “best practice” - from changing a tire to playing basketball to cooking. As able-bodied individuals, we are all physically capable of performing such activities, but how long it will take to complete? How many unnecessary steps do we take? How much additional effort and load do we put on our bodies mentally and physically? These questions can be addressed by learning and PRACTICING ideal mechanics. Sure, you can go out on a 1-mile run in a recommended shoe to begin your fitness journey but would you start your golf journey on the tee box of Hole 1 with your newly purchased clubs? No, likely you would work with a knowledgeable person on how to hold the club, general swing mechanics and practice several range balls before venturing to the course. Why should running be any different? Particularly in a sport where “novice” runners have a much higher risk of running related injuries (RRI) compared to experienced runners. In a study completed in 2018, authors found a 2x-injury rate in novice runners compared to experienced runners over a 4-yr period. Secondly, running is the cornerstone of several other sports so as you go out to shoot 100 free throws every day to practice your form, why wouldn’t you add drills to improve the form of getting from Point A to Point B on the court? It makes sense to make use of the studies on running form and body mechanics to begin a new fitness goal in order to give us an advantage - how many YouTube videos do you watch before endeavoring to fix the washing machine? Knowledge is power. The Pose Method works by identifying repetitive “poses” during a running cycle through which every runner must pass: they have been described as Pose (the typical running “picture”), Pull and Fall. For the next few weeks, we will be breaking down each phase. We will start with “the Pose.”

In our previous blog post, we highlighted the peripheral mechanisms of dry needling into muscle tissue. The benefits of trigger point dry needling have been well documented in the literature. However, this is only one component of needling in the treatment of neuro-muscular dysfunction. A comprehensive definition of dry needling should include nerves, ligaments, tendons, scar tissue, bone and teno-osseus junctions.1 This requires expanding beyond the trigger point model to consider additional peripheral, spinal and supraspinal mechanisms. The classic local twitch response is thought to be a strong neural impulse triggered from needling into multiple sensitize loci. Mirror local twitch responses have been recorded in the opposite trapezius muscle during dry needling of the symptomatic trapezius. This example suggests a consideration of central mechanisms in addition to local muscle dysfunction.1 A brief review of pain physiology is helpful in consideration of central dry needling mechanisms. Pain sensation originates in peripheral nociceptors that continue into sensory fibers, which feed into the central nervous system through the dorsal horn of the spinal cord.2 After connecting with spinal neurons, the pathway continues up the spinothalamic and spinoreticulothalamic tracts. These lead to supraspinal locations including the thalamus, parabrachial nucleus and amygdala. There is significant potential for both dysfunction and pain relief within this neural system.2 Throughout this discussion, the terms acupuncture and dry needling will be used interchangeably.1 While many studies use the term “dry needling,” others commonly use terms including TrP acupuncture, acupuncture needling and electroacupuncture. Several studies have used acupuncture and dry needling in the same title. All of these cases meet the strict definition of “dry needling”. This trend of discussing dry needling as acupuncture is commonly seen in the UK, Canada, USA and Germany.1 Acupuncture randomized control trials and other studies have commonly used western medical diagnoses including neck pain, knee osteoarthritis and plantar fasciitis.1 Furthermore, these studies applied needles into “Ah-Shi points,” which is Chinese for “auwh that’s where it hurts” or “that’s it.” These are synonymous with trigger points and are used in combination with non-trigger point targets. In this sense, it is beneficial for physical therapists to recognize the findings of appropriate biomedical acupuncture research.1 Studies have demonstrated that electroacupuncture involves many different mechanisms and bioactive substances, both peripherally and centrally for pain conditions.3 Peripheral release of endogenous opioids originate from lymphocytes, monocytes/macrophages and granulocytes. Sympathetic nerve fibers are additionally activated for opioid response. These opioids activate receptors on peripheral nerve terminals to decrease pain signaling back to spinal and supraspinal structures.3 Electroacupuncture has been shown to inhibit the sensory component of pain through spinal mechanisms including opioids, serotonin, norephinephrine and glutamate.3 Spinal opioid receptors are targeted to inhibit thermal hyperalgesia and mechanical pain thresholds. Low and high frequency electroacupuncture have been found to inhibit thermal pain during acute pain. Thermal, mechanical and spontaneous pain are inhibited in persistent pain conditions. Electroacupuncture influence on opioid receptors is thought to occur on both presynaptic primary afferent fibers and postsynaptic dorsal horn neurons.3 Electroacupuncture studies have also confirmed the involvement of spinal serotonin and norephinephrine in pain inhibition.3 This includes serotonin-containing nucleus raphe magnus neurons and norepinephrine-containing locus coeruleus neurons. Electroacupuncture also decreases glutamate receptor activity and induces release of spinal norepinephrine, which each inhibit pain signals at the spinal level. Pain reduction has also been noted with changes in glial cells, cytokines, signal molecules/pathways, dopamine and acetylcholine at the spinal level.3 Electroacupuncture benefits via supraspinal mechanisms have been noted with the contribution of many nuclei.3 Sensory components are mediated via nucleus raphe magnus, periaqueductal gray, locus coeruleus, arcuate, preoptic area, nucleus submedius, habenular, accumbens, caudate, septal area and amygdala. Opioid activity in the arcuate-periaqueductal gray-nucleus raphe magnus-spinal dorsal horn pathway are thought to be particularly important in this sensory realm. Several studies have shown that endorphin release blocks affective pain responses while controlling for sensory pain inhibition. This selective supraspinal influence on affective and sensory components of pain is a similar consideration for drug efficacy in pain management, including the use of morphine.3 The physical therapists at Evolution Sports Physiotherapy have been trained in a variety of needling techniques to meet the individual needs of our patients. Our comprehensive treatment approach respects localized tissue dysfunction in addition to central considerations based on clinical findings and assessment.
