The Selective Functional Movement Assessment (SFMA) is a comprehensive assessment used to classify movement patterns and direct manual therapy and therapeutic exercise interventions. Regional interdependence is the concept that seemingly unrelated impairments in a remote anatomical region may contribute to, or be associated with, the patient’s primary complaint. Often times, patients present with symptoms in certain locations, however, this particular area is not the cause of the symptoms. The SFMA utilizes a movement-based strategy in order to determine any movement pattern dysfunctions that may be contributing to any particular symptoms. There are numerous studies that have linked dysfunction in one area of the body with pain and dysfunction in another area of the body. The most common of these examples include hip impairments that are related to low back pain and thoracic spine impairments related to neck pain. In short, regional interdependence provides the theoretical support to assess and treat a non-affected body part. Rehabilitation professionals are the most highly trained healthcare professionals to function within this model.
The SFMA consists of 10 defined functional movement patterns that are considered top tier patterns. Shoulder a patient report pain during any of these movements, or exhibit “dysfunctional” movements as defined per certain criteria, the patient pattern will be broken into its individual parts, known as pattern breakouts. Utilizing these pattern breakouts, the rehabilitation professional is able to define impairments as either lack of mobility via Tissue Extensibility Dysfunction (TED), Joint Mobility Dysfunction (JMD), or Stability &/or Motor Control Dysfunction (SMCD). Utilizing this information, we can create a therapeutic plan to address all impairments that may be contributing to a patient’s symptoms.
Here at Fox Physical Therapy, our Doctor’s of Physical Therapy are SFMA certified. This allows us to conduct the highest quality, evidence-based approach to developing our patient’s plan of care. To schedule an appointment in Miami or Boca Raton, please call us at 305-735-8901 or click here.

Blood Flow Restriction (BFR) Training is a strategy involving the brief and intermittent occlusion of arterial and venous blood flow that occurs with use of a tourniquet placed around the proximal limb of the upper or lower extremity. When performing BFR for resistance training purposes, relatively light loads of around 20-30% of 1 RM allow a person to increase strength without the stress/strain of heavy loads.
Resistance training with BFR has also been shown to increase post-exercise muscle protein synthesis and elevate growth hormone levels. It can be used to improve muscle strength, size and functional aerobic capacity in shorter amounts of time with less stress on the body than typical resistance training. Blood flow restriction training (BFRT) essentially tricks the brain-body into thinking one is performing high-intensity exercise when, in fact, the loads are much lower. BFR can also be used to reduce muscle atrophy through passive applications and by creating cellular swelling.
BFR can be useful for rehabilitation, fitness, performance training or recovery and is ideal for populations who have limitations to high mechanical loads such as those who are bedridden, casted/braced, pre/postoperative and/ or elderly. In addition to these more fragile populations, BFRT can also be used on the athletic community for performance training.
BFR can be used in different ways depending on the goals and limitations of the individual. In all circumstances, the cuff is first applied as proximal on the limb as it can be placed. Next, the loss of pulse (LOP) is calculated using an ultrasound unit to determine at what pressure a person’s pulse in that limb can no longer be detected. Lastly, a pressure in the cuff is set depending on the type of BFR to be performed.
In Passive BFR (no exercise) used to reduce muscle atrophy and stimulate capillary growth, the cuff pressure is set to 100% LOP and a patient sits with the cuff on for 5-minute increments with 5 minutes of rest in between. In Cellular Swelling and Strengthening protocols, the cuff pressure is set between 40-50% for the upper extremity and 60-80% for the lower extremity. When strengthening, the intensity should be 15-30% of a person’s 1 rep max, and 4 sets should be performed (30 reps; 15 reps; 15 reps; 15 reps) with 30 seconds of rest between each set. A total of 5-6 exercises should be performed during the treatment session with 60 seconds of rest between each new exercise while the cuff is deflated.
If the goal is not strengthening, but cellular swelling, which reduces disuse atrophy and recruits muscle fibers (perhaps someone with ROM or WB restrictions), a person should perform 5 sets of 5 minutes with a 3-minute rest in between. This can be achieved with no exercise or while performing isometrics. These are but a few of the ways BFR can be implemented into a person’s rehabilitation or strength training program.

Eccentric strength refers to tension being applied to a muscle as it lengthens. This is also when the muscle’s force-producing capacity is most optimal. Studies show that eccentric exercise results in less oxygen consumption, greater force production, and less energy expenditure than concentric strengthening- or the active shortening of the muscle. The force produced by a concentric contraction is always less than the muscles maximum force. During a voluntary muscle contraction, the speed of the contraction and the ability to exert tension are inversely related. Therefore, the faster a muscle contract concentrically, the lower the tension it is able to generate. An example of concentric strengthening would be a classic bicep curl, whereas the eccentric component would occur as a person lowers the arm into a straightened position (as the bicep muscle lengthens).
Eccentric quadricep and gastrocnemius (calf) strength, in particular, are important following knee surgeries such as ACL reconstruction because of their importance in absorbing the weight of your body as they lengthen in order to control your descent- this includes going downstairs, sitting down in a chair or decelerating from a sprint. Without sufficient eccentric control, it would be difficult and, in some cases, unsafe to perform these activities. In regards to running, the primary muscles involved in acceleration and deceleration are quadriceps and gastrocnemius. However, acceleration involves the concentric contraction of these muscles, while deceleration involves the eccentric use of these muscles. Therefore, eccentric strength is important to safely slow down following a sprint or before initiating a rapid change of direction. Research suggests that eccentric strengthening on the non-involved lower extremity is also beneficial for improving both the quadriceps muscle strength and the quadriceps accelerated reaction time in the surgical lower extremity.
Though the idea of early post-operative eccentric resistance exercise to the surgical limb has traditionally been contraindicated, due to the potential for injury to the graft, articular cartilage, or surrounding soft tissue structure, recent evidence has shown that the application of early eccentrics to the ACL limb can be used to safely increase quadriceps muscle volume and strength. While eccentric quadriceps strength is important to regain following ACL reconstruction, it does not come without caveats. As with any eccentric training program, careful progression of training volume and intensity in the post ACL reconstruction patient is a necessity and should be performed under the direction of a licensed physical therapist as too much eccentric quadriceps strength could increase the chances of anterior tibial translation if not accompanied by sufficient hamstring strength. Therefore, a comprehensive approach, including both concentric and eccentric training to both the anterior and posterior chains surrounding the knee joint should be considered.
Eccentric exercise has the ability to be an effective means to manage many common orthopedic conditions such as tendinopathies, post-op recovery, and muscle strain prevention. This potential is based on muscle/tendon physiology as it relates to performance. Eccentric exercise, or when the muscle is lengthened and an external force exceeds the force produced by the muscle, has been shown to be more effective than traditional concentric strengthening at minimizing muscle atrophy and improving muscle force production. It results in less oxygen consumption, greater force production, and less energy expenditure and should be incorporated into both a preventative strength training program, as well as, an effective post-op rehabilitation protocol.

Functional Range Conditioning is a system of training which applies scientific methods to the acquisition and maintenance of functional mobility, articular resilience, and articular health and longevity. It was created by Dr. Andreo Spina and is quickly growing in popularity due to its effectiveness in training mobility of the human body. Mobility refers to the amount of active, usable motion that a person possesses. The more mobile a person is, the more they can maximize their movement potential safely and effectively. It is the difference between being flexible and able to stretch to specific passive ranges versus having actual control into those end ranges of motion. By training mobility one can capture what was once only passive ranges of motion and make them active and therefore usable. This, in turn, enhances the load bearing capacity of a joint and its ability to withstand the forces of everyday activity and sport.
Not only does FRC help to improve the mobility of the human body and develop improved load capacity in the joints, but it also improves body control. Body control is one of the critical factors in reducing the occurrence of injury and painful conditions that frequent training and sport.
To achieve the improvements in mobility, joint strength, and body control FRC implements two critical principles into the system. They are the principle of progressive adaptation and the principle of specificity. The principle of progressive adaptation states that incremental loads applied to the tissue results in adaptation of said tissue in such a way that the load absorption capacity will improve. This also makes FRC an inherently safe system to use. The loads applied to the tissues early on are scaled only to what that person can tolerate. As their tolerance improves so to will the articular strength of the joint. The principle of specificity states that the adaptation of the tissue is specific to the demand. This means by frequently incorporating end range mobility training into the maintenance and training of the human body, one is effectively injury-proofing themselves. The vast array of musculoskeletal injuries occur when tissue is loaded past what it can tolerate or the new demands on the tissue exceed what was previously the norm. By moving the joints of the body through all available ranges of motion and training into these ranges there will rarely be a situation the body is not already prepared for.
At Fox Physical Therapy we always seek to stay on the cutting edge of evidence-based practice. Dr. Fox and Dr. Alexander became certified in FRC last fall. FRC has seamlessly blended into the daily clinical practice and has only enhanced the already great outcomes expected here at Fox. If you are feeling stiff during sports or experiencing aching joints from a sedentary desk job, we encourage you to give us a call. Once in the clinic, you will learn how to perform the necessary maintenance work necessary to keep your body healthy and operating at optimal function.
This board certification identifies Physical Therapists who have gone above and beyond in their training in order to ‘specialize’ in the realm of orthopedics. In order to achieve the OCS designation, the Physical Therapist must demonstrate the required knowledge in identifying musculoskeletal dysfunction via a board examination.
The American Board of Physical Therapy Specialties identifies their mission statement as:
“The mission of the American Board of Physical Therapy Specialties is to advance the profession of physical therapy by establishing, maintaining, and promoting standards of excellence for clinical specialization, and by recognizing the advanced knowledge, skills and experience by physical therapist practitioners through specialist credentialing.”
It is important that if you are seeking care for an injury or chronic pain that you seek out a Physical Therapist that has achieved this OCS designation. This demonstrates that the Physical Therapist has taken the time to gain the required skills and experience in the realm of musculoskeletal disorders. This also, more importantly, ensures that you are receiving the best care possible.
If you thought you were experiencing an issue with your heart you would likely seek out the help of a Cardiologist, an MD who specializes the cardiovascular system, instead of a general practitioner. The same holds true for your Physical Therapist. If you have an injury to the bones, joints, or associated muscles it is in your best interest to seek out care from a Physical Therapist who is an Orthopaedic Clinical Specialist.
At Fox Physical Therapy our mission is to provide the best orthopedic evidence-based musculoskeletal care in South Florida. Our board-certified Doctors of Physical Therapy will quickly identify and resolve your pain without the need for medicine or surgery. We have two locations in Wynwood, Miami, and Boca Raton.
The relationship between MRI changes and low back pain may not be so clear-cut. In fact, research shows that changes on an MRI don’t necessarily correlate to pain, while many patients with pain show no abnormalities on MRI. Before jumping to any conclusions, read on for more detail on the complex relationship between what your image shows and whether is it ultimately driving the pain and symptoms you are experiencing.
First, if you’re experiencing back pain, you are not alone. Pain in the lower back is one of the most common musculoskeletal complaints. In fact, 8 out of 10 people will experience low back pain over their lifetime. About 1 out of 4 people experience chronic low back pain (lasting longer than 3 months). Any structure of the lumbar spine that is innervated by nerve endings can cause both low back pain and/or referred pain, which is felt in one or both lower extremities. Some of the more common potential structures that may be involved include muscles, ligaments, vertebrae, facet joints (joints connecting the vertebrae), dura mater ( a membrane that surrounds and protects the spinal cord), and nerve roots.
Imaging is useful in detecting fractures, abnormal tissue growth (i.e. cancer), inflammation/ bleeding, as well as serious compression of the spinal cord or nerves, which can help direct appropriate treatment. However, 99% of people with low back pain will not have any of these serious conditions. A large percentage will, however, have incidental findings on imaging which are normal anatomical variants, as well as normal age-related changes. In these cases, imaging is much less helpful in identifying the true cause and directing treatment. In fact, several studies have found that pain in the lower back is more strongly associated with factors such as life dissatisfaction, neuroticism, hostility, extroversion, and poor sleep quality than it is with findings on imaging. Thus, obtaining an imaging report can sometimes cause more harm than good. Research shows that patients who undergo lumbar MRI generally have worse outcomes than similar patients who do not have to image. Much of this is attributed to psychological factors, misinformation, and negative emotional responses. One common example is the finding of “dark” T2 signals within the disc on MRI. This is most often a pain-free and benign condition. However, it is labeled degenerative disk disease (DDD) leading many patients to believe their spine is “deteriorating.” In turn, these inappropriate beliefs can lead to a decrease in activity, anxiety, lifestyle changes, a perception of increased pain, changes in motor patterns, and unnecessary surgeries.
The exact nature of the relationship between imaging and pain is unclear, largely due to abnormal imaging findings in large numbers of people without pain (false positives). This means that many of the “abnormal” findings are indeed commonly occurring and natural parts of the aging process. One of the more common findings in the lumbar spine is disc degeneration, which is a natural process beginning fairly early on in life. In fact, more than one-third of healthy, normal adults in their 20’s present with degenerative discs on imaging. In some individuals, the rate of degeneration is quicker than others due to a combination of genetic and autoimmune factors, as well as resorption and biomechanical factors. In any case, the volume of intervertebral disc tissue naturally decreases over the lifespan.
As one can see the current research on medical imaging does not support the notion that what is seen on the image correlates strongly with what the patient is experiencing. In fact, it has been shown that a thorough physical examination leading to a mechanical diagnosis can be just a sensitive and specific in identifying the cause of your symptoms. An evaluation by a qualified Doctor of Physical Therapy can help reveal the underlying biomechanical deficits that may have contributed to your condition and prevent it from recurring in the future. Some of the benefits of physical therapy include pain relief, increasing mobility, strengthening of the core and lumbar stabilizers, and increasing balance and functional movement.
At Fox Physical Therapy, our board-certified therapists specialize in treating and relieving low back pain. Contact us today to find out how we can help you feel better.
The McKenzie Method of Mechanical Diagnosis and Therapy (MDT) is a unique method of treating spine and extremity pain. The method has been in development for over 60 years, originally created by Robin McKenzie. It is an in-depth assessment, diagnosis, and treatment process that has been well researched throughout the years. Its validity as a treatment method for musculoskeletal pain is consistently supported in the literature. It requires no surgery, medication, needles, or expensive equipment.
The research has shown the MDT assessment to be extremely reliable in identifying pain of a mechanical origin. Mechanical pain originates from a biomechanical dysfunction in the way the bones, joints, or associated muscles are moving. The vast majority of musculoskeletal pain, including neck and low back pain, falls into this category.
Per the McKenzie Institute’s website: “The treatment principles of the McKenzie Method promote the body’s potential to repair itself and do not involve the use of medication, heat, cold, ultrasound, needles, or surgery. McKenzie allows patients to learn the principles and empowers them to be in control of their own symptom management, which can reduce dependency on medical intervention.”
Here at Fox Physical Therapy, we use the MDT assessment as one of our primary methods to effectively treat low back and neck pain. During the assessment, one of our Doctors of Physical Therapy will help to determine the exact cause of your symptoms as well as implement a treatment plan to quickly resolve your symptoms. The best part of the MDT method is that it allows you, the patient, to gain control over your symptoms and keep them under control even when outside of the clinic setting.
If you have been experiencing pain or issues with your body and its performance contact us today. You may be experiencing an underlying biomechanical that needs to be addressed by one of our doctors.

Chances are if you play a sport that requires repetitive kicking then you are familiar with the term hamstring strain or “pulling a hamstring”. Hamstring strains account for 12–16% of all injuries in athletes with a re-injury rate reported as high as 22–34%. Hamstring strains are a very common and nagging injury typical seen in athletes who perform high speed sprinting, repetitive kicking and explosive movements associated with acceleration and change of direction. This injury accounts for 38% and 28% of the lower extremity injuries seen in high school and college football respectively and makes up the highest percentage of total injuries in rugby. The high incidence of injury in this muscle group may be partly due to the fact that the hamstrings cross over two joints (the hip and the knee) and are therefore subject to much greater reaction forces at multiple points along the lower extremity chain. The hamstrings are a colloquial term used to describe three distinct muscles, two on the medial side (semimebranosus, semitendinosis) and one on the lateral side (biceps femoris). All three muscles are responsible for bending the knee and extending back the hip, two actions that are crucial for sprinting, jumping, and kicking. These muscles originate from the hip and turn into tendons that with two attaching to the inside of your leg bone and one attaching to the outside, crossing the knee joint. A muscle strain is a term used to describe damage or a tear to the muscle/ tendon. Like most injuries, a strain can range from a simple overstretch injury all the way to a complete tear of the muscle.
How do they happen?
What most of the literature agrees upon is that hamstring strains are typically caused by a non-contact injury secondary to forceful stretching. Building off this point; when analyzing running technique it has been shown that peak stress on the muscle occurred during a terminal swing phase of the sprint (see image), suggesting that this period may pose the greatest risk for injury. It is during this phase that the hamstrings are working to decelerate the leg while also controlling the degree to which your knee straightens. What this essentially means is that the type of contraction the hamstrings have to perform must switch extremely rapidly from slowing down the leg while it is straightening (the point of peak stress and stretch to the muscle) to then actually driving your hip back to propel you forward. Several research studies support that this rapid change from deceleration to acceleration by the hamstrings is when the muscle is most vulnerable to injury.
Severity of Strains
The severity of muscle strain injuries is generally categorized as Grade I: very mild tear of the muscle with minor strength loss, Grade II: partial tear of the muscle with mild bruising and significant strength loss that limits functional performance, and Grade III: complete tear of the muscle/tendon and severe disability with day to day activities. Complete tears like a grade III are rare, constituting about 1% of all hamstring strains. What is commonly observed with grade I and II strains is that in the middle of sprint, hurdle, jump, or kick the athlete will feel a tightness or pulling type pain in his posterior thigh that will cause him to stop physical activity.
Do not let this become a chronic issue!
The scary thing about hamstring strains is that the rate of re-injuring the muscle is very high, meaning that it can easily transition to a chronic problem if not correctly addressed. Across the board, the absolute biggest risk factor for having a hamstring strain is…. a previous hamstring strain. In fact, a study done on 500 amateur soccer players showed that a previous hamstring strain has been shown to increase the risk of a recurrence up to six times as much. The logical question is why does this happen? Since the symptoms of a grade I and grade II hamstring can be uncomfortable /annoying but tolerable during activities of daily living, the athlete often prematurely returns to activity after rest. This may lead to repeatedly unsuccessful efforts to return to sports without letting the muscle heal adequately. Thus, the muscle is not strong enough to tolerate the usual demands of sport which leads to another strain, or worse, a complete tear.
How can physical therapy help?
Risk factors shown to correlate with an initial hamstring strain are decreased hamstring flexibility, poor muscular strength/ endurance, poor core stability, lack of proper warm-up, inability to disassociate the trunk from the lower extremities, and poor lumbar posture. Our board-certified Doctors of Physical Therapy at Fox Physical Therapy will be able to identify any of these aforementioned deficits during the biomechanical evaluation. From there a plan of care will be implemented to correct the impairments quickly and efficiently. Remember the biggest risk to recurring hamstring strains is having that first hamstring strain, so even if you are not injured we can help to identify possible risk factors ensuring you stay at peak performance levels. Don’t wait until you break down to seek treatment. That’s the equivalent of letting your car break down on the side of the road before finally getting an oil change.
In the event that you do sustain a hamstring strain, physical therapy becomes of the utmost importance to guide and progress the athlete through his/her rehabilitation and prevent an acute injury from becoming chronic. Current literature supports that clinical diagnosis of a grade I/II strain by an experienced physical therapist is as reliable and valid as ultrasound and MRI, meaning that one does not necessarily have to wait to go to a doctor and then wait again to get an MRI in order to begin the rehabilitation process. In Florida, anybody can directly access their Physical Therapist without the need for referral.
