ORTHOTIC THERAPY for the GOLF HEALTH PRACTITIONER by Dr. Cherye Roche – Sports Chiropractor


There is an old saying that goes; “It is not the notes that make the music, but the spaces betwee the notes that make the music beautiful”.  This quotation can be applied to the relationship between the golf swing, and the paces between the golf swings.  It would go something like this; “It is not the golf swing that creates chronic pain in the golfer, but the paces between the swings that are the root cause of the chronic pain”.  The understanding of the meaning of this concept is critical in the clinical application of orthotic therapy in golfers.  Read on to discover how you can have a real impact on the health and wellness of your golf patients and revolutionize your practice as well.

It has been calculated that in an 18 hole round of golf, the average golfer will spend approximately 3 hours walking, 1 hour preparing to hit the ball and only 4 minutes actually swinging to strike the ball! Therefore, I draw the conclusion that chronic injuries in the lower extremity, pelvis and spine, may not be related to the golf swing itself, as much as they are related to the chronic stress placed on the weight bearing joints during the 3-4 hours that it takes to walk 18 holes of golf.  The following describes the underlying principles to support this hypothesis. 

Biomechanical weaknesses in the foot can be the root cause of chronic musculoskeletal conditions in the foot, ankle, knee, hip, pelvis and spine. Correcting these biomechanical weaknesses is the key to resolving chronic conditions in the golfer, or any patient suffering with chronic pain.  Functional Orthotic Therapy (FOT) in clinical practice is defined as, the prescription of foot orthoses (shoe inserts) used for the support and correction of these biomechanical foot faults.  A variety of practitioners use arch supports and/or orthotic devices in the management of foot/ankle complaints, however, this discussion is primarily related to the use of orthotic devices in the management of chronic conditions throughout the entire closed kinetic chain, including the lower extremities, pelvis and spine. These conditions are commonly seen in clinical practice.   FOT can be incorporated as part of an overall plan of management that may also include manipulative therapy, physiotherapeutics, functional rehabilitation, etc.

Abnormal torsional forces placed on the joints and soft tissues during the walking gait cycle are related to the underlying biomechanical faults in the closed kinetic chain of human locomotion.  As an example; typically golfers present with chronic, recurring, ankle, knee, hip, sacroiliac, lumbosacral or lumbar facet syndrome / joint dysfunction, with associated ligamentous, tendinous, and muscular irritation.  In the case of a chronic complaint, manipulation, physiotherapeutics, and rehabilitation usually provide varying levels of relief, for varying periods of time.  When a golfers condition does not resolve with standard treatment, consider the potential underlying biomechanical weakness that may be precipitating the chronic irritation to the joints and soft tissues.  In many cases, you will find that there is an asymmetrical pronation of the feet, both statically and dynamically. 

Bilateral asymmetrical pronation syndrome (BAPS) is a common finding in patients with chronic conditions of the weight bearing joints.  When one foot pronates to a greater degree than the other, torsional forces impact the weight bearing joints up the kinetic chain, as a function of ground reaction forces. 

Imagine that the right foot overpronates.  This causes the tibia to internally rotate, the femur to internally rotate, the right ilium to rotate anteriorly, the lumbar spine to rotate body left (spinous right), the thoracic and cervical vertebrae also rotate in the same direction, and as a result of cervical left rotation, the coupled motion results in cervical left lateral flexion.    

Now, go back through that whole sequence of events in the joints, and consider how the soft tissues would have to adapt and respond to compensate for this excessive torsional stress at each of these joints.  Most commonly this phenomenon results in medial longitudinal arch pain, medial knee pain, lateral hip pain, bilateral sacroiliac pain, and most commonly, pain at the transitional regions of the spine. (SI, L/S, T/L, T/C and C0/C1) Therefore, although a standard regimen of treatment may give temporary relief, it is not uncommon for our golf patients to return with a chronic recurrence of the signs and symptoms associated with their chronic conditions.  Remember that the site of chronic pain is often not the source of the pain. Therefore, we are compelled, by professional integrity and clinical curiosity, to investigate all of the possible aetiologies contributing to the patient’s condition.  Once we identify the true cause of the complaint, we can apply the appropriate clinical interventions to achieve resolution of the condition.  Functional orthotic therapy can be a highly effective management tool in facilitating the correction of these underlying biomechanical faults and ultimately helping the patient to realise relief from his/her chronic musculoskeletal condition.  

This knowledge may modify the way you examine a patient.  In taking a history you will want to listen for clues about how the patient’s condition manifests in their activities of daily living.  Patients with an underlying biomechanical weakness will often have an increase in symptoms late in the day, have lower extremity joint pain, in addition to pelvic and spinal pain, and will have an increase in symptoms with long term standing, walking or running.  Golfers will note that they are a bit stiff when warming up, feel OK on the front 9, but experience a gradual increase in symptoms over the last few holes. They may also indicate a past history of plantar fasciitis (arch pain), posterior tibial disorder (shin splints), generalized knee or hip pain that is episodic depending on the frequency, intensity and duration of their golf activities.  

Observation of the static posture will reveal bilateral asymmetrical pronation of the feet with associated internal tibial rotation and “squinting” patellae, pelvic obliquity, scoliotic - like flexion /rotational changes in the spine, shoulder unleveling and head tilt.  I have found that most practitioners have been taught to observe posture from the top down.  I would challenge you to consider examining from the ground up, and to observe how the changes in the posture of the feet can influence the rest of the structures up the kinetic chain.  Furthermore, you will want to observe the golfers posture at address, full back swing and full follow through. Overpronation of the feet will lead to restrictions in lower extremity rotation at the beginning and end of the swing.  Resulting in abnormal compensatory movement elsewhere.

On physical examination, you will often find that the classic orthopedic tests are negative, or not true positives.  We have all seen knee, hip and low back pain patients with no true positive orthopedic or neuralgic tests, but who clearly have dysfunction in the joint(s) of interest that we can identify with palpation, other signs and symptoms, and by history.  You may also find that many of these patients characteristically have palpatory tenderness in the medial knee, lateral hip, and paraspinal soft tissues in the transitional areas of the spine (SI, L/S, T/L, C/T and C0/C1).

Once you have decided that your golf patient would benefit from FOT, the next step is to decide what type of device to prescribe.  There is a wide spectrum of sophistication regarding the types of orthotic devices available to practitioners.  The patient with an uncomplicated case of plantar fasciitis may well be helped with a simple over the counter (OTC) device, which will provide basic arch support for the medial longitudinal arch and offer relief.  However, the patient with chronic recurring sacroiliac, lumbosacral and thoracolumbar dysfunction will require a customised, or custom pair of biomechanical devices to correct the dysfunctional relationship between the rearfoot and forefoot, as well as supporting the arch.  In general, the further up the kinetic chain the condition manifests, the more sophisticated the device that is necessary to correct the underlying biomechanical faults.  Orthoses purchased OTC by the patient do not require any specific measurements other than size.  However, with a customized or custom device, some form of measurement or impression is necessary to satisfy more exacting requirements.  Orthoses can be customized through the use of heat molding, fluid injection, or foam impressions.  In these cases a basic orthotic template is modified in an attempt to individualize the orthoses to the patient’s feet.

There is also digitized pressure plate analysis which generates a digital image of the pressure patterns created through the weight bearing portion of the gait cycle.  This pattern is then used to generate a customized device to match the patient’s foot function and provide dynamic support.  Finally, plaster casting is used to create a negative impression of the foot.  This negative impression is used by a lab to either fill with plaster to make a positive impression, from which the orthotic is manufactured, or it is scanned with a CAD/CAM system to create a digital positive impression that is used in computer assisted manufacturing of the device.  This, however, generates a non-weight bearing impression that does not account for dynamic forces through the foot.  There are advantages and disadvantages to each of these methods of capturing the function, impressions and contours of the foot.  In addition, there is ongoing debate regarding the relative benefits of weight bearing versus non-weight bearing measurements / impressions.  Also, there is the question of the types of materials used to manufacture the orthotic devices.  These debates are too detailed to address in this article. However, in my experience, they will all work with varying degrees of success in the hands of a properly trained professional.  I hasten to note that proper training is readily available and easy to achieve for most practitioners of musculoskeletal health care.  What is most important in incorporating FOT in clinical practice, is a solid base of basic anatomy and biomechanics along with some common sense, wisdom, good clinical judgment, compassion for the patient, and a clinical curiosity to seek out the best solution for the patient. 

Over the past 15 years, as I have presented lectures, seminars and workshops on the subject of FOT, practitioners want to know which system I use.  The answer is that I have used them all at one point or another in my private practice.  For many years I used non-weight bearing, neutral position plaster casting as the only method for prescribing orthoses.   This method is very time consuming, labor intensive, and messy, but was the best method at the time.  I attempted using heat molding, injection molding, foam impressions, and a variety of systems wherein a basic template was modified with various forefoot and rearfoot posts.  Again, all of these systems worked with varying degrees of success.  However, they were all time consuming in one way or another or have a relatively low level of specificity.  With golfers, specificity is critical due to the challenge of walking 5-6 miles on grass, with an unpredictable surface, requiring a great deal of intrinsic adaptation from the foot.  In addition, a few millimeters of overpronation can lead to a marked limitation in swing mechanics.

In the last few years I have been introduced to digital pressure plate scanning as a method for prescribing orthoses.  I now use this method almost exclusively in my private practice.  It takes just a few minutes to scan the patient, the results are sent electronically to the lab, and the customised devices are delivered within 10 days to the office for dispensing to the patient.  The devices do not require any further modification as they are individualised to the patient.  On rare occasion I see a patient that I feel requires a fully custom device.  In this situation I cast the patient to generate a negative impression of the patient’s foot, along with the pressure plate analysis.  The cast is mailed to the lab and the digital data is sent electronically as usual.  The lab then can combine the data from the digitised scan with the data that they generate when they scan the negative cast with their CAD/CAM device.  Then a fully custom pair of devices are generated.  This process takes longer due to the mailing, and therefore is only use with patients who have gross anatomical or functional anomalies, or for elite athletes with special needs.  In general, the vast majority of my patients do very well with a digitised scan and the customised device that it generates.  Furthermore, the graphics that are instantly available as a paper print out, facilitate patient education and compliance.

 Functional orthotic therapy is a simple and powerful modality to consider in developing a plan of management for golfers with chronic musculoskeletal pain conditions.  It is generally not used in acute or sub-acute situations, with a few exceptions.  The use of orthoses with these patients yields positive clinical outcomes. Therefore, patient satisfaction is very high.  As patients begin to feel better and have their handicaps improve, they share their experience with others, which creates new patients for your practice.  It also creates a clinical environment that is fun, exciting, profitable, and interesting to work in.  Resolving chronic pain and getting patients well is always more fun than simply managing chronic pain.  Furthermore, if you are using the GaitScan method of evaluation, it can help you build your practice.  The system is very portable, so it can be set up in the local Golf Club as a patient demonstration, education, and recruitment tool.  The dynamic nature of the system and the colorful graphics make it very attractive to golfers, teaching pros, etc.  Once these athletes see how dysfunctional their gait pattern is, they are keen to see you for advice regarding their chronic physical complaints.
 
The addition of FOT to your treatment regimen of manipulation, physiotherapeutics and rehabilitation will revolutionize your practice.  I encourage every musculoskeletal practitioner, to spend the minimal time, effort and money that are required to add this very powerful modality to your clinical practice.  I hope that this article stimulates your clinical thinking.  Please contact me with questions or for information about upcoming seminars in your area, or the addition of the GaitScan system in your practice.
