In the face of musculoskeletal pain, it’s common to restrict activity. Unfortunately, doing so can weaken the muscles and joints in the affected area, which can prolong pain and elevate the risk for future injury. Patients with osteoarthritis of the knee often fall into this trap. So, what type of exercises are best for improving knee strength in the presence of knee osteoarthritis?
First, let’s define two types of muscle activity that can occur during exercise: eccentric and concentric. During a bench press, when you’re pushing the barbell upward, the muscles in the chest shorten in a concentric motion. As you lower the bar downward, your pectoralis muscles lengthen, which is an eccentric motion.
A 2019 study that involved 54 seniors with knee osteoarthritis investigated which of the two phases builds better strength for the knee – the concentric/muscle shortening phase or the eccentric/muscle lengthening phase of muscle activity. The participants were split into three groups: CNC RT (concentric resistance), ECC RT (eccentric resistance), or CON (control group – no exercise/wait-list group). The two exercise groups received four months of supervised exercise training using traditional weight machines with proper set-ups and instructions that emphasized the concentric or eccentric phase of the exercise.
Each week, participants completed questionnaires to measure knee pain and disability. The researchers also recorded the maximum weight each subject could lift with respect to knee flexion, knee extension, and the leg press.
The results showed that BOTH exercise groups experienced strength increases in comparison to the control group, with the eccentric resistance group achieving greater gains on the leg press and knee flexion exercises, but not for knee extension. Both exercise groups also reported less pain and disability than the control group. The authors concluded that both types of resistance training effectively improved leg strength, pain, and function, and they recommend that the mode an individual emphasizes should be based on personal preference, goals, tolerance, and equipment availability.
This study is a great example of the many benefits that exercise can offer for an elderly population suffering from knee osteoarthritis. Doctors of chiropractic often prescribe exercises for patients with knee pain in addition to providing manual therapies, modalities, orthotics (knee braces and foot orthotics), as well as dietary and nutritional counselling for inflammation reduction and pain management purposes. Before throwing in the towel and jumping to a total knee arthroplasty (replacement), you owe it to yourself to seek less invasive management strategies FIRST.

The cervical spine relies heavily on muscular support, particularly from the deep muscles in the front and back of the neck. Some experts estimate that up to 70% of the stability of the cervical spine arises from these deep neck muscles, particularly those in front of the spine. Studies have demonstrated that the rapid acceleration-deceleration forces that are placed on the neck during a motor vehicle collision can injure these deep neck muscles. Indeed, electromyographic (EMG) testing conducted on WAD patients has shown that those with higher pain intensity also had reduced deep muscle function in both the front and back of the spine. Treatment guidelines for non-specific neck pain recommend incorporating neck-specific exercises into the treatment process. But what about for WAD patients with neck pain?
A 2018 study that involved 26 patients with chronic WAD (symptoms lasting longer than three months) evaluated the role of neck-specific exercises (such as cranio-cervical flexion—tucking in the chin and approximating the chin toward the chest while looking straight ahead without bending the head forward) had in improving muscle performance, disability, and pain intensity over the course of a three-month time frame.
After three months, the researchers used a special type of diagnostic ultrasound to measure function in one large superficial muscle and two deep muscles that all reside in the front of the neck. Investigators observed that the participants in the neck-specific exercises (NSE) group experienced significant improvements with respect to muscle function, disability, and pain intensity that were not observed among those in a “wait list” group who served as controls.
Here’s where it gets more interesting… At the three-month point, the members of the control group were added to the NSE group, and three months later, the researchers observed that these participants experienced the same improvements that they previously noted in the first NSE group! This study supports the need for specific neck exercises to reduce pain and disability and improve function.
When the deep muscles are injured, it’s common for the body to recruit superficial muscles to help stabilize the body and maintain posture. While this can protect the deep muscles from further injury in the short term, it can decondition these muscles over time and allow fatty deposits to infiltrate its tissue. This helps to explain why exercises are so important in the recovery process from musculoskeletal injuries, especially since there’s research that says that up to half of WAD patients will still experience pain and disability a year after their accident. This underscores the importance of seeking treatment for WAD as soon as possible in order to reduce the risk for chronicity and while the chances for full recovery are greatest.

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, or pinched nerve, in the extremities. The condition is estimated to affect 3-6% of the population, often in both hands. Let’s discuss what causes CTS, its symptoms, how it’s diagnosed, and how it’s treated…
Causation: Carpal tunnel syndrome occurs when pressure is placed on the median nerve as it travels through the wrist. This can be due to inflammation caused by obesity, repetitive movements, pregnancy, arthritis, hypothyroidism, diabetes mellitus, trauma, mass lesions, amyloidosis, sarcoidosis, multiple myeloma, leukemia, and more. Women are at a greater risk for CTS than men, due to having a smaller wrist and possibly hormonal reasons.
Symptoms: Pain, numbness, and tingling are common CTS symptoms that affect the thumb, index finger, middle finger, and the thumb-side of the ring finger. Symptoms can radiate up into the forearm and even into the shoulder and neck. Weakness in grip strength and nighttime/sleep interruptions are also common symptoms.
Diagnosis: The patient history is very important for diagnosing CTS, as it provides the doctor information to help determine if CTS is likely or if another condition is causing the patient’s symptoms, such as ulnar tunnel syndrome or dysfunction elsewhere along the course of the median nerve. The “flick sign” (flicking the fingers to “wake them up”) predicts electrodiagnostic abnormalities 93% of the time with a false-positive rate of <5%. Other in-office tests include provocative tests (reproducing symptoms), neurological tests for sensation (sharp vs. dull), and strength-muscle tests. More advanced electrodiagnostic tests (EMG/NCV or electromyogram/nerve conduction velocity) can quantify the severity of CTS and verify the diagnosis.
Treatment: All treatment guidelines recommend conservative, non-surgical care prior to surgery unless there is a unique, unusual case like trauma (fracture), or some other unusual situation. THIS IS WHERE CHIROPRACTIC SHINES! Besides “usual” non-surgical care (night splinting, anti-inflammatory measures, exercises, and ergonomic modifications), chiropractic treatment includes manual therapies such as soft tissue release techniques and joint manipulation. A 2018 study reported that following manipulative therapy, patients experienced an increase in the front-to-back diameter and roundness of their carpal tunnel, which reduced pressure on the tunnel’s contents. Chiropractors also perform manual therapy based on neurodynamic techniques, which a 2019 study concluded were highly effective in a group of patients with mild-to-moderate CTS.
It’s important to note that patients are more likely to achieve a successful outcome if they seek treatment earlier in the course of the disease than if they wait months or even years. If you experience the symptoms associated with CTS, seek care sooner rather than later!

Experts estimate that whiplash associated disorders (WAD) from motor vehicle collisions (MVCs) affect about 300 for every 100,000 people in the Western each year. Suffice it to say, that’s a lot of people!
Crash tests have demonstrated that the risk for whiplash is much greater when the backrest is leaned backward and/or when a headrest is lacking (in older cars) or is too low in relation to the head. The key is to prevent the head from extending backward over the top of the seat, which can lead to more severe soft tissue injuries in the neck. While it’s not always possible to anticipate an MVC, past research has shown that looking forward at the time of the collision may reduce WAD injury/severity risk.
On the topic of necks, individuals with thinner necks have a greater risk for injury, which may explain why woman are more often affected by WAD than men. However, regardless of whether you are male or female, staying fit and keeping the neck muscles strong is important. It’s been suggested that individuals with a history of neck pain are more likely to experience more severe whiplash injuries, as are those in poor general health. There are conflicting studies that report that seat belt use may increase the risk for WAD, but after reviewing multiple studies, the consensus is that seat belts save lives, so buckle up!
In many cases, WAD patients may miss work, especially if they have a job with high physical demands. Patients with more severe injuries may miss up to twenty-five days of work, while those with minor injuries may still be out for up to ten days. One study found that about 31% of the 800 cases the researchers looked at took no time off work, 52% returned to work after only four days off, and 90% returned within thirty days off. About 4.9% of the patients in the study were still not working after twelve weeks.
Several factors suggest a WAD patient may experience a slower or more limited recovery: a history of neck pain; loss of neck motion measured post-MVC; increased sensitivity to cold stimulation; high pain levels post-MVC; less severe crash-type; dizziness, arm pain or numbness; low back pain; and poor expectations of recovery.
The good news is that treatment guidelines have consistently recommended spinal manipulation— he primary form of treatment provided by doctors of chiropractic—for managing whiplash-related injuries.

A 2009 study that monitored over 8,800 elderly French adults found that an individual’s blood pressure can fluctuate with the seasons. In particular, the researchers observed that as temperatures fell, both systolic and diastolic blood pressure could rise to unhealthy levels, but they were unable to determine why.
However, a study published just five years later may have solved the mystery. The solution has to do with the molecule nitric oxide. Nitric oxide is a vasodilator, meaning that it causes the walls of blood vessels to relax and expand, with a resulting reduction in blood pressure.
Researchers have discovered that nitric oxide is stored in the dermal vasculature at levels much greater than are found circulating in the bloodstream. When exposed to long-wave ultraviolet (UVA) rays, the skin releases some of that stored nitric oxide into the bloodstream. Because individuals tend to spend less time in the sun during the winter months, there are fewer opportunities for the skin to release nitric oxide into the blood, dilate blood vessels, and moderate blood pressure. This may also help to explain why stroke and blood vessel rupture (aneurism) are more common in the winter months among the elderly.
How can one maintain healthier levels of nitric oxide in their bloodstream when it’s not convenient to spend time in the sunshine? The answers may be found in diet and exercise.
A 2018 study found that eating leafy greens and root vegetables and drinking beetroot juice effectively increased nitrate plasma (blood) levels for the purpose of enhancing exercise performance.
In 2020, researchers observed that schoolteachers in South Africa with greater physical fitness levels had higher levels of nitric oxide in their blood, as well as lower systolic and diastolic blood pressure readings. The research team concluded, “These results may suggest that even moderate physical activity could increase nitric oxide synthesis capacity, which in turn may mitigate the development of cardiovascular disease in this population.”
The take home message is that to maintain a healthier blood pressure, consider getting plenty of sunshine, eating leafy green and root vegetables (or drink beetroot juice), and exercising!

One of the symptoms commonly associated with whiplash associated disorder (WAD) is headaches. The current research suggests that up to 50% of patients who experience whiplash-associated headaches may continue to suffer from them for up to a year or more, and many of those will continue to have headaches as late as five years following their whiplash injury event. There are many potential causes for WAD-related headaches, which can include cervical injury, jaw dysfunction (TMJ), psychological distress (depression and anxiety), brain structure abnormalities (concussion), and/or overuse of headache medications.
To address these potential causes of whiplash associated headaches, treatment may include the following:
MANUAL THERAPIES: Mobilization and manipulation, which are commonly used by doctors of chiropractic, have been demonstrated to be effective for reducing pain and improving function for many conditions, including WAD and headaches of cervical origin. Treatment may also involve massage and physical therapy modalities, depending on the patient’s needs.
EXERCISE: A review of research published between 1990 and 2015 found that craniocervical, cervicoscapular, and posture correction exercises can be helpful in the treatment of whiplash-related headaches.
STAY ACTIVE: Try to carry on with normal activities within pain tolerances, as movement is needed to keep soft tissues healthy and to ensure a continuous supply of nutrients to the cervical disks. Don’t use a cervical collar to immobilize the neck unless directed to do so by your doctor.
NUTRITIONAL SUPPORT: There are several vitamins and supplements that have been shown to reduce inflammation and/or reduce pain. These include flavonoids, curcuminoids, omega-3 fatty acids, taurine, and vitamin D. Adopting an anti-inflammatory diet can also aid in the healing process.
Doctors of chiropractic frequently use a combination of these approaches when managing WAD patients to help reduce pain and disability and assist the patient in returning to their normal activities as soon as possible.

With many sports requiring overhead movements that can place the shoulder at the extreme end of its range of motion, it’s not surprising that shoulder injuries are so common among athletes. For instance, up to 50% of NCAA college football players have some history of shoulder injury, which comprises about 10-20% of total injuries in the sport. When looking at collegiate quarterbacks, one study found that shoulder injuries accounted for more than half of injuries among players in the position. When it comes to sport-related shoulder injuries, these are the three most common (and to complicate matters, they often co-occur):
1) SLAP (or labrum) tears: Superior (top) Labral tear from Anterior (front) to Posterior (back) tear is a term used to describe a torn piece of cartilage located along the rim of the socket. The labrum adds depth to the cup, which helps to stabilize the ball in the socket. Individuals with a SLAP tear will often report a loss of motion and power, a feeling like their shoulder could pop out of socket, and a deep ache that is hard to pinpoint when attempting overhead movements.
2) Shoulder instability or dislocation: With contact sports, there’s the opportunity for a collision that can dislocate the ball of the shoulder joint (the end of the humerus bone) from the shoulder socket. Because the muscles in the front of the shoulder tend to be larger and stronger, the dislocation will more often occur in that direction. Symptoms can include a severe, sudden initial pain followed by short bursts of pain as well as swelling and a noticeable deformity in the appearance of the shoulder.
3) Rotator cuff tears (RCTs): This is common in sports that require repetitive overhead motion like baseball (especially among pitchers), swimming, and tennis. Symptoms include a deep, hard to locate ache, weakness, and reduced range of motion (especially overhead or to the back).
In general, early/prompt care yields the best results. While there are instances when a prompt surgical procedure is warranted, treatment guidelines typically emphasize non-surgical therapies first with surgery only after all other options have been exhausted.
Chiropractic management of these conditions will often involve a multi-modal management approach that includes manual manipulation and mobilization to the shoulder’s multiple joints, the neck, and the mid back; specific shoulder exercise instruction; physical therapy modalities (ice, electrical stim, ultrasound, laser, pulsed magnetic field, and more); and nutritional recommendations.

Carpal tunnel syndrome (CTS) is a condition that occurs when the median nerve is compressed as it passes through the wrist. One treatment option available to patients is carpal tunnel release surgery, which severs the carpal tunnel ligament to reduce pressure on the affected nerve to resolve the numbness, pain, tingling, and weakness symptoms associated with CTS. When is surgical treatment for CTS necessary and when should a non-surgical option be pursued?
The short answer is that surgery should only be considered as a first option in an emergency situation, such as a serious wrist fracture that pinches the median nerve. Beyond that, treatment guidelines generally advise patients to exhaust non-surgical, conservative approaches before consulting with a surgeon. Aside from potentially higher healthcare costs and a prolonged recovery, surgery also carries the risk for serious complications. Another thing to consider is that the current research suggests that jumping straight to surgery may not necessarily produce better long-term outcomes than non-surgical treatment options.
In one randomized clinical trial, researchers recruited 120 female CTS patients to receive either surgery or a conservative treatment approach that involved manual therapies. The research team evaluated each patient after one month, three months, six months, and one year. In the short term—one month and three months—the results favored the conservative approach. However, both groups reported similar outcomes after six months and one year.
The same research team repeated the study with another group of female CTS patients and reported similar results. In the short term, conservative care achieved greater results while both approaches had similar outcomes over the long term.
A systemic review that looked at results from ten studies involving patients with confirmed CTS in one or both hands came to a similar conclusion. The review found that non-surgical care provided more satisfying results in the short term with both approaches achieving similar results over time.
While these studies show that conservative treatment to reduce pressure in the carpal tunnel is an effective option for the CTS patient, doctors of chiropractic will also examine the full course of the median nerve to identify other places the it may be compressed, such as the neck, shoulder, and elbow. Median nerve compression in these areas can often co-occur with CTS and will need to be addressed to achieve a satisfactory result.

Neck pain is one of the most common complaints that drive patients to seek chiropractic care. Sometimes the cause of injury is a known traumatic event, but in many cases, neck pain is the result of wear and tear from poor posture—forward head posture in particular.
The head, which weighs 10-11 lbs. (4.5-5 kg), typically rests above the shoulders. When an individual’s head leans forward to look at a computer screen or to look downwards at their smartphone/tablet, the muscles in the rear of the neck and upper back/shoulders need to work harder to keep the head upright.
Experts estimate that for each inch (2.54 cm) of forward head posture, the head feels about 10 lbs. heavier to the muscles that attach to the back of the head and neck. To illustrate this, pick up a 10-pound object like a bowling ball and hold it close to your body. Then, hold it away from your body with your arm outstretched and feel how much heavier it seems and the strain it places on your body to maintain that position for even a short time.
In the short term, forward head posture is something the body can manage, but over time, the muscles can fatigue and the strain can injure the soft tissues in the back of the neck, shoulders, and upper back. To adapt, some muscles may become stronger (and some may atrophy), the shoulders can roll forward, the cervical curve can straighten, etc. Researchers have observed that forward head posture can also reduce neck mobility, especially with rotation and forward flexion movements. While these changes can lead to several negative health issues, neck pain is perhaps the most obvious and common.
When a patient presents for chiropractic care for neck pain, postural deficits will likely need to be addressed to achieve a satisfactory outcome. This can be achieved with manual therapies to restore proper motion in the affected joints and with exercises to retrain the muscles that may have become deconditioned. Additionally, a patient will need to develop better postural habits, especially when interacting with their electronic devices. While the process can take time, the good news is that it’s possible to reduce forward head posture, which can also lower the risk for neck pain recurrence.

When it comes to managing a low back condition, the goal of chiropractic treatment is for the patient return to their normal daily activities as soon as possible. This not only means addressing low back pain but also low back disability, including impaired postural control and reduced spinal stability, which can manifest in reduce position sense, increased postural sway, and impaired balance.
Movement control and spinal stability are controlled the deep muscles, the superficial muscles, and the nervous system that sends information to and from the brain. Dysfunction in ANY of these can result in lumbar spine instability.
To complicate matters, when an injury is present, the body will alter its neuromotor patterns as a protective mechanism. However, this can lead to some muscles becoming overworked while others may become deconditioned. If unaddressed, additional musculoskeletal conditions may result in nearby parts of the body, which explains why patients will often present with multiple seemingly unrelated complaints.
In addition to manual therapies like manipulation and mobilization to restore proper joint movement, treatment for low back pain may also include core stabilization/strengthening exercises and balance exercises.
For abdominal strengthening, one exercise that works well is a spine-sparing sit-up. Place the hands behind the lower back to prevent flattening of the lumbar curve and lift the head and chest as a unit a few inches off the floor, hold for ten seconds, and repeat to tolerance (five to ten reps to start out with).
To strengthen your sides, try a side-bridge or side-plank (from feet or knees), holding for ten seconds and repeating as tolerated.
To strengthen the back, try the front plank. Rest on your forearms in a push-up position for ten seconds and repeat as tolerated. The bird dog is another good exercise. Kneel on your hands and knees and raise the opposite arm and leg without twisting the trunk and hold for ten seconds, repeat with the other arm/leg.
For improved balance, stand on one leg with your eyes open or closed (if able) as long as you can. This stimulates the neuromotor system. Be safe, and do these in a corner to prevent falling!
Make these exercises a habit. Consistency will help improve low back function and you’ll reduce your risk for a future episode of low back pain!
