Education Alone Does Not Improve Outcomes In Patients With Acute Low Back Pain
low back pain-back pain-treatment-physical therapy

In any profession, utilized interventions and methods change with incoming ideas and evidence. New concepts and treatments often advance ahead of clinical research trials aiming to support or refute their utilization. Within Physical Therapy, pain neuroscience education has become a popular topic of late. Education topics regarding the development and chronicity of persistent pain are being utilized to teach patients about their current symptoms. Although helpful, I often find some clinicians over utilize this intervention in place of other proven strategies in the management of patients with musculoskeletal pain. A recent study examined the impact of intensive pain education among patients with acute low back pain.

Traeger and colleagues published their findings on the impact of intensive low back pain education and self management strategies in the Journal of the American Medical Association Neurology (2018). Authors randomized 202 patients with acute low back pain to two, one hour sessions of either placebo education (active listening, without information or advice) or patient education (biopsychosocial aspects of pain, back pain self management). These education sessions were in addition to other first line treatments for low back pain including pain medication. Authors reported no improvement in pain outcomes between the education and active listening groups. Consistent with clinical management of acute low back pain, education should not be used in isolation but rather in conjunction with other proven treatments including spinal manipulation and exercise.

How Does Exercise Heal Injured Tissues?
boulder-tendon-muscle-injury-treatment

Each day we meet with athletes, clients, and patients who present with an injury or condition involving an injury to a muscle, nerve, ligament, tendon, or bone.  One of the most powerful tools we have to accelerate the healing of this injury is exercise.  A previous post discussed the impact of Physical Therapy exercises on Achilles Tendinopathy.  This post described the impact on exercise on achilles tendinopathy and how exercise improves injured tissue a process called mechanotransduction.  Mechanotransduction refers to the process by which the body converts mechanical loading into cellular responses (Khan Br J Sp Med 2015).  

Khan et al. in a recent article used the term "mechanotherapy" to describe the benefits of Physical Therapy exercises on injured tissues in the body (Br J Sp Med. 2015).  These authors updated the definition of this term to include "the employment of mechanotransduction for the stimulation of tissue repair and remodeling".  Each day we utilize exercise parameters including direction of force, speed, intensity, frequency, duration, and others to optimally impact a patient's injured tissue in order to promote healing and restoration of function.  Each tissue in the body seems to have unique responses to loading from Physical Therapy exercise.

A common example of this phenomenon occurs in our bones.  Gradual loading of the bones through exercise improves bone density, but aging and a lack of weight bearing exercise can lead to osteoporosis.  Bone cells (osteocytes) are stimulated through loading in weight bearing and exercise to promote fracture healing in injured bones.  Research by Challis et al. examined the impact on loading in addition to standard fracture care in patients with forearm fractures (Aust J Phys 2007, J Bone Joint Surg Br 2006, Clin Orthop Relat Res. 2005).  The authors noted improved fracture healing, strength, and range of motion when fractures were exposed to low load, cyclical pressures from a pneumatic cuff wore under the cast.  This suggest gentle, controlled loading in addition to immobilization may accelerate fracture healing. 

Muscle and tendon offer us some of the best examples of exercise's impact on tissue.  The benefits of exercise on muscle are clearly known including increased size (hypertrophy) due to loading (weight training) and the loss of muscle size due to disuse or immobilization (cast).  After a brief period of controlled rest after a muscular injury (strain) exercise has been shown to positively effect the cellular healing and repair of these injured tissues (Jarvinen et al. Best Pract Res Clin Rheumatol. 2007).  Without proper loading these injured muscles may remain in a weakened state making them more prone to subsequent injury.  We often see this in recurrent injuries such as hamstring strains.

Ohberg et al. examined the impact of achilles tendon exercises on achilles tendinopathy.  These patients demonstrated quick improvements in pain and function, but they were also followed over the coming years to determine how their tendons healed from this exercise (Br J Sp Med 2004).  The authors noted improved tendon structure with 19/26 tendons returning to "normal" quality on ultrasound imaging.  As described in our previous blog post early pain relief and restoration of function is likely due to a different mechanism than tendon restructuring since these changes often take years to develop. 

In short, Physical Therapy exercise will always be a hallmark conservative treatment for the regeneration of injured tissues.  Utilize a Physical Therapist to learn how to best manage your injury and how to utilize specific exercise parameters in get back to life and sports. 

Short or Long Duration Isometrics Equally Effective For Patellar Tendinopathy

Patellar Tendon pain, also known as jumper's knee, is a painful condition most commonly seen in athlete's engaged in jumping sports such as track and field, basketball, and volleyball.  Common causes of this condition include training errors (too much too soon) and underlying weakness in the quadricep and hip musculature.  The gold standard of treatment for this condition involves the application of sub maximal loading through Physical Therapy exercises to promote healing (remodeling) of the tendon.  In short, doing too little is as bad as doing too much.   Exercise begins to heal the injured tissue through a process called mechanotransduction and without it tissues remain in an immature, weakened condition.  In the knee, promising research is being conducted showing the immediate and short term benefits of isometric loading (45-60 seconds), but new research suggests patients may benefit from shorter loading times.  

In the Clinical Journal of Sports Medicine, Pearson and colleagues randomized patients with patellar tendinopathy to one of two groups (2018).  Patients were placed in either a short duration (24 sets of 10 seconds) or long duration (6 sets of 40 seconds) isometric loading program at 85% of their maximum voluntary contraction.  As you can see from the prescriptions time under load (240 seconds) was balanced between groups.  Authors reported the short duration isometric loads were as effective as the longer duration isometric loads as long as the time under tension was equalized.  This study provides more flexibility to both patients and Physical Therapists when treating patellar tendinopathy.  The take home message is load injured tissues sub maximally to promote an optimal healing environment.

Physical Therapy Improves Pain, Strength, and Function Among Patients with Full Thickness Rotator Cuff Tears

Previous research has documented no difference in long term outcomes between Physical Therapy and surgery for patients with rotator cuff tears.  Many patients with rotator cuff tears, including massive tears, do well with conservative treatment of their shoulder injuries demonstrating improvements in pain, strength, and function.  Strength training makes up the foundation of conservative care for this injury.  A recent review of the evidence documents the power of strength training for patients with rotator cuff injuries.

A review of the available evidence in the International Journal of Sports Physical Therapy highlights the evidence of 35 studies examining the use of strength training for patients with rotator cuff injury (Jeanfavre et al. 2018).  The authors reported on the results of strength training on 2010 shoulder with a rotator cuff tear.  Further, they found 73% of these tears were greater than 1 cm and 37% were classified as massive.  37% of these tears were traumatic in nature and 58% of patients experienced symptoms greater than 1 year.  Authors reported 78% of patients improved their symptoms and 85% improved their strength and function after Physical Therapy.  Interestingly, only 15% of patients elected for surgery following a course of Physical Therapy highlighting the effectiveness of conservative management of this injury.

Physical Therapy Shown To Be Deterrent of Future LBP Flare Ups

Death, taxes, and low back pain are three of the certainties of life with over 90% of individuals reporting low back pain at some point in their lives.  Our previous posts have described the ability of Physical Therapy to both accelerate a patient's recovery from low back pain and reduce its' risk of recurrence.  A recent study examined the factors that are correlated with a "flare up" or exacerbation of symptoms in patients with acute LBP.  

Authors studied 48 patients with low back pain (<3 months duration) and assessed for periods of either baseline symptoms or flare ups described as a period of increased pain lasting at least 2 hours (Suri, P et al. Spine. 2018).  Prolonged sitting, > 6 hours, was the only activity significantly associated with a flare up.  Patients who sat greater than 6 hours were 4 times more likely to have a flare up.  Mental health, including stress or depression, was also associated with a low back pain flare up.  The authors showed patients undergoing Physical Therapy treatments reported significantly less flare ups.

Utilizing Spinal Manipulation for Chronic Low Back Pain

The Journal of the American Medical Association recently reviewed the evidence on the utilization of spinal manipulation for patients with acute back pain.  Authors reported moderate evidence to support its' use to both decrease pain and improve function.  The majority of research on spinal manipulation is currently being performed by Physical Therapists to determine best practice patterns for its' utilization, as well as, the mechanisms behind its' effectiveness.  A recent review article was published on spinal manipulation's effects on patient's with more persistent low back pain.

Coulter and colleagues pooled the data of 9 trials including over 1100 patients with persistent low back pain (The Spine Journal. 2018).  The authors reported spinal manipulation significantly reduced low back pain and disability.  In addition, spinal mobilization was found to also reduce pain within patients with low back pain.  The authors found spinal manipulation produced a larger effect on these treatment outcomes than spinal mobilization.  In our Boulder Physical Therapy practice we find spinal manipulation to be effective in the short term to reduce pain and disability allowing a rapid transition to advanced exercise programs.  Long term relief of low back pain is best achieved using core, upper and lower body strengthening programs.
