How common are rotator cuff tears?
1. A Spine Journal study found that in patients suffering from cervicogenic headache, spinal manipulation cuts the number of symptomatic days in half:
“256 adults with chronic cervicogenic headache (CGH) were randomized to four dose levels of chiropractic SMT: 0, 6, 12, or 18 sessions. Participants were treated three times per week for 6 weeks and received a focused light-massage control at sessions when SMT was not assigned. A linear dose-response was observed for all follow-ups, a reduction of approximately 1 CGH day/month for each additional 6 SMT visits. Cervicogenic headache days/month were reduced from about 16 to 8 for the highest and most effective dose of 18 SMT visits. Cervicogenic headache intensity showed no important improvement nor differed by dose.”
Incidentally, SMT proved to be more effective than massage for CGH.

3. As many as 96% of persons over age 50 years may have shoulder abnormalities involving the rotator cuff. Many of these individuals remain asymptomatic. Now a new study has found the incidence and prevalence of subclinical supraspinatus pathology in young subjects may be significantly greater than expected:
“Forty-six subjects, having no shoulder pain or known functional impairment were assessed using physical screening and musculoskeletal sonography. Results showed that 24% of these asymptomatic shoulders demonstrated degenerative changes.”

4. A study in Spine Journal found that sheep that underwent L3/4 spinal fusion experienced significant degenerative changes:
“(In fused specimens) The MRI and histologic analysis demonstrated significant disc degeneration. The mechanical environment set up by immobilization alone is capable of inducing lumbar disc degeneration.”

5. A study in the Journal of Bone & Joint Surgery found that lumbar epidural steroid injections increase the risk of osteoporotic vertebral compression fracture by 21%, per injection:
“Each successive injection increased the risk of fracture by a factor of 1.21. The findings suggest that Lumbar epidural steroid injections, like other forms of exogenous steroid administration, may lead to increased bone fragility.”

9. A randomized clinical trial compared the effectiveness of a splint vs. KinesioTape (KT) for the management of carpal tunnel syndrome:
“A significant improvement was observed in the KT group compared to the splint group in terms of electrophysiological changes, provocative test responses, symptom severity, and functional status scores. KT may help prevent the disease from progressing further in mild and moderate idiopathic CTS when applied in time using the appropriate technique and be a good alternative to neutral splinting in terms of patient compliance.”

Evidence-based chiropractors explain the disconnect between symptoms and imaging findings.
Recently, Daimon K et al. (2018) published a landmark study for EVERY evidence-based chiropractor. It highlights the notion that degenerative changes are merely age-related and do not necessarily correlate with symptoms. This study assimilates two decades of sequential imaging to prove that there little association between degeneration and clinical symptoms:
“results of our statistical analysis and the different rates of disc degeneration versus clinical symptoms reported here and elsewhere, the degenerative findings on cervical MRI do not appear to be generally associated with the development of clinical symptoms.” (1)
Structural findings take months or years to progress. Acute symptoms usually occur within moments to days after a trauma, or change in activity, movement, hobby, or habit. Structural abnormalities can complicate tissue failure, but are not directly correlated with symptoms. It is essential that we focus on what is correctable and what is not. There is no treatment to eliminate the degenerative changes in the spine; however evidence-based chiropractic care can effectively and efficiently resolve symptoms.
Arthritic and degenerative changes are a fact of life. It is important not to focus on what shows up on imaging but rather focus on what we can do with the cards that were dealt.
“the rate of degenerative progression at one intervertebral disc level on MRI over the 20-year period was 95.3%, whereas the rate of the development of clinical symptoms was 66.9%. Statistical analysis of the relationship between the progression of the 5 degenerative findings in the cervical spine and the occurrence of clinical symptoms only detected a significant association between foraminal stenosis and upper limb pain.”
When a patient presents with a one-week onset of neck pain; is it from their stenosis? NO! The cervical narrowing has been there for years. Is it a complicating factor? YES. We treat the patient’s symptoms by focusing on the functional reasons the pain started. Once the pain is gone, the stenosis will still be there. Our office educates the patient to not blame their arthritis for every malady affecting their life. We focus on their habits, hobbies, and postures to eliminate the stressors on their body that are exacerbating their spinal condition. This same paradigm works for disc pathology, or chronic meniscus injuries, or SLAP lesions, or…(name your chronic structural lesion)
“A study of clinical symptoms and cervical MRI findings by Siivola et al. showed that neck and shoulder pain in young adults was not associated with disc degeneration, an annular tear, or disc protrusion on MRI.”(2)
Lower back pain is an undesired consequence of the activities that our patients partake in on a daily basis. Without appropriate intervention and adequate rest, these repetitive stressors can lead to injury.
Desk jockeys are filling chiropractic offices with complaints triggered by cumulative stressors, compounded by inactivity. Prolonged seated postures and general deconditioning lead to overloaded spinal ligaments, muscles, and discs.
Altering seat and keyboard height, as well as monitor elevation & distance are all critical variables for those who spend their day sitting. But more recently, increasing numbers of workstation users are transitioning to standing desks; and standing in one spot for an extended period is not without its own set of risks.
What advice should an evidence-based chiropractor give to patients concerning their standing workstation?
Do you know why taverns have foot rails around their bars? The foot rails originated during a time when stools were not common, and patrons would stand, i.e. ‘belly up to’ the bar. The rail was intended to give patrons the ability to alternate legs, giving one a rest while providing a little flexion for those stenotic cowboy spines.
A new study examined the impact of standing workstations on LBP. (1) The authors concluded that one variable, footrest height, had a significant contribution to muscle fatigue and lower back pain. Their recommendation:
“The results suggest that a footrest height of 10% of the body height can be recommended as a normalized height for prolonged standing work in subjects with a history of non-specific lower back pain during prolonged standing.”
The take away from this is to incorporate a foot rest with your standing workstation. You can't argue with the evidence!

3.The Journal of Rheumatology published an articulate narrative on the genesis of arthritis: “Following skeletal maturation, chondrocyte numbers decline while increasing senescence occurs. Lower cartilage turnover causes diminished maintenance capacity, which produces accumulation of fibrillar crosslinks, resulting in increased stiffness and thereby destruction susceptibility. Mechanical loading changes proteoglycan content. Moderate mechanical loading causes hypertrophy and reduced mechanical loading causes atrophy. Overloading produces collagen network damage and proteoglycan loss, leading to irreversible cartilage destruction because of lack of regenerative capacity. Thus, age seems to be a predisposing factor for OA, with mechanical overload being the likely triggering cause.” Jorgensen AE et al. The Effect of Aging and Mechanical Loading on the Metabolism of Articular Cartilage The Journal of Rheumatology April 2017, 44 (4) 410-417
4.“The knee is the most common site of OA. Numerous studies have shown an inconsistency between patients’ reports of pain and their radiographic findings. This inconsistency may be partially explained by the fact that a portion of the pain originates from the myofascial trigger points (MTrPs) located in the surrounding muscles. Treatment focusing on MTrPs seems to be effective in reducing pain and improving function in OA patients.” Dor, Adi et al. A myofascial component of pain in knee osteoarthritis. Journal of Bodywork and Movement Therapies , Volume 21 , Issue 3 , 642 – 647
5.In patients undergoing MRI for degenerative spinal disease, expanding the regional study to include a T2 whole spine screen identified incidental findings in 15.8% of patients, 4.3% of which required further medical or surgical intervention. The authors concluded: “Considering the potential advantages in identifying significant incidental findings and the minimal extra time spent to perform whole spine screening, its application can be considered to be incorporated in routine imaging of spinal degenerative diseases.” Kanna, R.M., Kamal, Y., Mahesh, A. et al.

Medline contains more than 24 million articles, with almost one million new citations added each year. Evidence-based chiropractors know that they must employ and continually refine “best practices” to obtain great outcomes. The following up-to-date chiropractic research review offers 11 new studies that impact our patients and practices.
1.A new paper provides additional confirmation that patellofemoral pain syndrome (PFPS) and dynamic knee valgus do not arise from within the knee, rather from hip abductor/ external rotator weakness and/or foot hyperpronation: “The most effective intervention programs included exercises targeting the hip external rotator and abductor muscles and knee extensor muscles.” and “PFPS patients with foot abnormalities, such as those with increased rearfoot eversion or pes pronatus, may benefit the most from foot orthotics.”Petersen W, Rembitzki I, Liebau C.

10.Belief about the relative risk of acute lumbar disc herniation (LDH) resulting from chiropractic spinal manipulation varies by profession. Chiropractors generally fell into a group with the most optimistic views, believing that chiropractic SMT reduces the incidence of acute LDH by about 60%. Family physicians expressed a neutral belief, while orthopedic surgeons comprised the majority of a group with the most pessimistic views believing that chiropractic SMT increases the incidence of acute LDH by about 30%.

11.An electromyographic study confirms that athletes with rotator cuff tendinopathy demonstrate an aberrant patter of scapular movement, i.e. delayed activation of the serratus anterior and lower trapezius. This muscular dysfunction impairs upward rotation of the scapula resulting in further rotator cuff impingement. Leong HT. et al. Rotator cuff tendinopathy alters the muscle activity onset and kinematics of scapula. J Electromyogr Kinesiol 2017 Aug;35:40-46.
