JOINT MOBILITY IS ESSENTIAL
Updated: May 20, 2022
Improving joint mobility is critical if you are going to address the body's full kinetic chain. In fact, we are greatly reducing the effectiveness of any myofascial technique if we don’t address restrictions in joint mobility.
The effects of joint mobilization/manipulation can be divided into two primary categories mechanical, and neurophysiological. Although each of these subjects could fill several textbooks, we will try and mention just a few key points in this discussion.
Mechanical Considerations Behind Joint Mobility
Our capacity to produce an unlimited variety of movements requires good joint integrity. As practitioners, it is important for us to understand the complex interrelationships between the structure and function of multiple joints.
No joint ever works in isolation. For example, the stability of shoulder is often affected by the joints of the cervical and thoracic spine, and even by the upper extremity joints of the elbow and wrist. An injury in one joint often creates compensations in both adjacent and distant joints.
The same fascia that infuses our muscles, ligaments, tendons, osseous structures, neurological, and cardiovascular structures also connects directly into the joint capsules. Our fascia is the ultimate physical manifestation of a kinetic chain.
Research has shown us that when joints become immobile, as in injury or osteoarthritis, then they become subject to several physiological changes.
This includes a decrease in fluid content, which in turn can cause a decrease in the joint-fiber distance within the capsule surrounding the joint.
This in turn causes the development of increased cross-fiber linkages, which can then cause adhesion formation in the synovial folds of the joints. These adhesions cause a decrease in the strength of collagenous tissue, which can then cascade into tissue failure, even with diminished tissue loading. (1, 2)
Effects of Joint Mobilization/Manipulation
The objective of joint mobilization is to reverse these physiological changes by promoting movement between capsular fibers.
Research has shown that joint mobilization can gradually cause rearrangement of collagen tissue to increase mobility.
In addition joint manipulation can break adhesions within the joint capsule and help to increase the length of capsular fibers. (3)
Though the best evidence to support this has focused on the short-term effects of joint mobilization, clinically we have found that it is possible to retain these changes over the long-term, by combining mobility exercises with strengthening routines.
Keep in mind that the joint capsule is not the only structure that is positively affected by joint mobilization. Other peri-articular tissues, such as ligaments, tendons, muscles, and fascia, also improve in function when joint mobilization techniques are used.
Research has shown that mobilization and manipulative techniques result in a number of beneficial neurological effects. One of the most positive effects is a reduction of pain.
Research has shown that after joint manipulation, there is an increase in what is called the pain-pressure threshold (the minimum force applied which induces pain). (4) This could be due to changes in b-endorphin and serotonin levels, an alteration in alpha motor neuron activity, or to changes in the autonomic nervous system (ANS) responses. The reality is that there is no definitive consensus between researchers.
What we do know is that the pain experienced by the patient is greatly reduced after joint manipulation. (5) Seeing a reduction in the patient's pain should not be taken lightly. Pain reduction can give patients an opportunity to:
Normalize their movement patterns
Perform their prescribed exercises
Increase their level of functional activities of daily-living.
All of which promotes long-term functional and physiological changes. (6)
There is also good evidence that mobilization/manipulation of joints produces changes in muscle activity. Some of these changes include an increased ability for force generation by the muscle, and a decrease in muscle hyper-tonicity. This is seen for both for spinal musculature during spinal manipulation in the extremities during extremity manipulation. (7, 8)
Joint Manipulation & Joint Mobilization
The Power of Chiropractic Adjustments
Chiropractic Adjustment are powerful tools. When patients who suffer from chronic back pain receive care, at regularly pre-planned intervals, (Chiropractic Maintenance Care), then they do much better as compared to patients who only receive care during episodes of acute back pain.
Neck Adjustment Verses Neck Mobilization – Which one is for me?
The practitioner should always determine if neck adjustments are appropriate for the patient’s specific case. For patients who would prefer NOT to have their neck manipulated, we offer a safe, effective alternative using Neck Mobilization to release restrictions in the neck area (cervical region).
Although Neck Manipulation is a great tool for removing joint restrictions, cervical manipulation is not always appropriate for many of our patients. For example, we do NOT manipulate the necks, of patients over a certain age, patients with severe osteoarthritis or osteoporosis, patients with certain autoimmune conditions such as Rheumatoid Arthritis, or various other conditions.
Cervical Joint Mobilization - MSR
In this video I demonstrate examples of Cervical Joint Mobilization, which we also teach to other practitioners during our Motion Specific Release (MSR) courses. (53)
Caution: These MSR Protocols should only be performed by certified MSR practitioners, and are not for practice by the general public. The videos we provide are strictly for demonstration purposes!
