Hip Abductor Weakness

One very important job of your hip muscles is to maintain the alignment of your leg when you move. One of the primary hip muscles, the gluteus medius, plays an especially important stabilizing role when you walk, run, or squat. The gluteus medius attaches your thigh bone to the crest of your hip. When you lift your left leg, your right gluteus medius must contract in order to keep your body from tipping toward the left. And when you are standing on a bent leg, your gluteus medius prevents that knee from diving into a “knock knee” or “valgus” position.

Weakness of the gluteus medius allows your pelvis to drop and your knee to dive inward when you walk or run. This places tremendous strain on your hip and knee and may cause other problems too. When your knee dives inward, your kneecap is forced outward, causing it to rub harder against your thigh bone- creating a painful irritation and eventually arthritis. Walking and running with a relative “knock knee” position places tremendous stress on the ligaments around your knee and is a known cause of “sprains”. Downstream, a “knock knee” position puts additional stress on the arch of your foot, leading to other painful problems, like plantar fasciitis. Upstream, weak hips allow your pelvis to roll forward which forces your spine into a “sway back” posture. This is a known cause of lower back pain. Hip muscle weakness seems to be more common in females, especially athletes.

You should avoid activities that cause prolonged stretching of the hip abductors, like “hanging on one hip” while standing, sitting crossed legged, and sleeping in a side-lying position with your top knee flexed and touching the bed. Patients with fallen arches may benefit from arch supports or orthotics. Obesity causes more stress to the hip muscles, so overweight patients may benefit from a diet and exercise program. The most important treatment for hip abductor weakness is strength training. Hip strengthening is directly linked to symptom improvement. Moreover, people with stronger hip muscles are less likely to become injured in the first place.

Trigger points in the triceps muscle.

The tricep muscle is named for its three heads long, medial, and lateral. The long head originates on the infraglenoid tubercle, the medial head on the posterior humerus, and the lateral head on the posterior humerus as well. They join together to insert on the Olecranon process of the ulna. The triceps function to extend the elbow. Strong extension under resistance can cause trigger points to form. Pain referred from triceps trigger points can be felt in the posterior shoulder and down the posterior forearm, as well as in in the olecranon process and the lateral epicondyle which can cause “tennis elbow” pain.

My knee hurts; I must have bad knees….

​knee

Due to bipedal locomotion (walking around on two legs), foot and ankle problems have the potential to affect EVERYTHING above the feet—even the knees!

When analyzing the way we walk (also known as our gait), we find when the heel strike takes place, the heel and foot motion causes “supination” or the rolling OUT of the ankle. As the unloaded leg begins to swing forwards, there is a quick transition to pronation where the heel and ankle roll inwards and the medial longitudinal arch (MLA) of the foot flattens and pronates NORMALLY!

During the transition from supination to pronation, the flattening of the MLA acts like a spring to propel us forwards followed by the “toe off”, the last phase, as we push off with our big toe and the cycle starts with the other leg. However, if you watch people walk from behind, you will see MANY ankles roll inwards too much. This is call “hyperpronation” and that is NOT NORMAL!

So at what point does this normal pronation become hyperpronation? The answer is NOT black and white, as there is no specific “cut-off” point but rather, a range of abnormal. Hence, we use the terms mild, moderate, and severe hyperpronation to describe the variance or the degrees of abnormality.  Hyperpronation can lead to the development of bunions and foot/ankle instability that can cause and/or contribute to knee, hip, pelvis, and spinal problems—even neck and head complaints can result (the “domino effect”)!

One study looked at the incidence of hyperpronation in 50 subjects who had an anterior cruciate ligament (ACL) rupture vs. 50 without a history of knee / ACL injury. They found the ACL-injured subjects had greater pronation than the noninjured subjects suggesting that the presence of hyperpronation increases the risk of ACL injury.

Doctors of chiropractic are trained to evaluate and treat knee conditions of all kinds. Often this may include prescribing exercises or utilizing foot orthotics in an effort to restore the biomechanics of the foot, which can have positive effects not only on the knees but also further up the body.

Work Station Ergonomics Advice

When dealing with Upper Crossed Syndrome the ergonomics of your workstation should be at the from of mind. Some workstation ergonomics advice is as follows:

ErgonomicsWorkstation

✓ Maintain proper body position and alignment while sitting at your desk – Hips, knees and elbows at 90 degrees, shoulders relaxed, feet flat on floor or footrest.
✓ Wrists should not be bent while at the keyboard. Forearms and wrists should not be leaning on a hard edge.
✓ Use audio equipment that keeps you from bending your neck (i.e., Bluetooth, speakerphones, headsets).
✓ Monitors should be visible without leaning or straining and the top line of type should be 15 degrees below eye level.
✓ Use a lumber roll for lower back support.
✓ Avoid sitting on anything that would create an imbalance or uneven pressure (like your wallet).
✓ Take a 10-second break every 20 minutes: Micro activities include: standing, walking, or moving your head in a “plus sign” fashion.
✓ Periodically, perform the “Brugger relief position” -Position your body at the chair’s edge, feet pointed outward. Weight should be on your legs and your abdomen should be relaxed. Tilt your pelvis forward, lift your sternum, arch your back, drop your arms, and roll out your palms while squeezing your shoulders together. Take a few deep cleansing breaths.
Addressing these areas will help reduce your symptoms, make your care more effective and the duration of pain decrease. If you need help with ergonomics or want more information, please contact us at info@aberdeenchiropratcic.com

Pathophysiology of trigger points.

A large number of factors have been identified as causes of trigger point activation. These include acute or chronic overload of muscle tissue, disease, psychological distress, systemic inflammation, homeostatic imbalances, direct trauma, radiculopathy, infections, and lifestyle choices such as smoking. Trigger points form as a local contraction of muscle fibres in a muscle or bundle of muscle fibres. These can pull on ligaments and tendons associated with the muscle which can cause pain to be felt deep inside a joint. It is theorized that trigger points form from excessive release of acetylcholine causing sustained depolarization of muscle fibres. Trigger points present an abnormal biochemical composition with elevated levels of acetylcholine, noradrenaline and serotonin and a lower ph. The contracted fibres in a trigger point constricts blood supply to the area creating an energy crisis in the tissue that results in the production of sensitizing substances that interact with pain receptors producing pain. When trigger points are present in a muscle there is often pain and weakness in the associated structures. These pain patterns follow specific nerve pathways that have been well mapped to allow for accurate diagnosis or the causative pain factor.

Upper Crossed Syndrome/Desk Neck

Upper crossed syndrome

Your posture plays an important role in your overall health. Poor posture leads to chronic strain and discomfort. “Upper crossed syndrome” describes poor posture that results from excessive tightness in your shoulders and chest with weakness in your neck and mid-back. This combination forces your shoulders to roll inward and your head to project forward.

To help understand how upper crossed syndrome causes trouble, think of your spine as a telephone pole and your head as a bowling ball that sits on top. When the bowling ball is positioned directly over the top of the upright post, very little effort is required to keep it in place. If you tip the post forward and the ball begins to roll over the edge of the post, significantly more effort would be required from the muscles trying to hold it there. This effort results in chronic strain of the muscles of your neck and upper back.

The chronic strain is uncomfortable and may also lead to neck pain, upper back pain, headaches, TMJ pain, and ultimately- arthritis. This postural problem is exceptionally common in computer workstation users.

Correction of this problem is accomplished by stretching the tight muscles, strengthening weak muscles, and modifying your workstation. Treatment is aimed at reducing and eliminating symptoms through the use of Chiropractic adjustments, soft tissue release, acupuncture and trigger point therapy.

Diagnosis of trigger points.

Diagnosis of trigger points typically takes into account symptoms, pain patterns, and manual palpation. When palpating the therapist will feel for a taut band of muscle with a hard nodule within it. Often a local twitch response will be elicited by running a finger perpendicular to the muscle fibres direction. Pressure applied to the trigger point will often reproduce the pain complaint of the patient and the referral pattern of the trigger point. Often there is a heat differential in the local area of the trigger point.

Trigger points in the biceps Brachii muscle.

The Bicep Brachii is perhaps the most recognizable muscle in the body. It’s the muscle that is most often flexed when someone says ” show me your muscles”. It is composed of two heads, the long head and the short head. The short head originates on the coracoid process of the scapula, and the long head on the supraglenoid tubercle. Both heads merge to insert on the radial tuberosity and bicipital aponeurosis into the deep fascia on the medial part of the forearm. The main actions of this muscle are elbow flexion and forearm supination(rotation with the palm of the hand going upward). This muscle also assists shoulder flexion. Trigger points in this muscle mainly refer pain into the shoulder, with spillover into the posterior aspect above the scapula. A less common referral is into the anterior elbow and forearm.

What is a trigger point

Dr Janet travel coined the term trigger point in 1942 to describe clinical findings with characteristics of pain related a discrete irritable point in muscle or fascia that was not caused by acute trauma, inflammation, degeneration, neoplasm or infection. The painful point can be palpated as a nodule or tight band in the muscle that can produce a local twitch response when stimulated. Palpation of the trigger point reproduces the pain and symptoms of the patient and the pain radiates in a predictable referral pattern specific to the muscle harbouring the trigger point.

Do I have a cuff tear?

​Infraspinatous

One of the most common causes of shoulder pain is a rotator cuff (RC) tear. To determine just how common this is, one study looked at a population of 683 people regardless of whether or not they had shoulder complaints. There were 229 males and 454 females for a total of 1,366 shoulders. (The participants’ average age was 58 years, ranging from 22 to 87 years old.)

The research team found 20.7% had full thickness rotator cuff tears. Of those with shoulder pain, only 36% had tears found on ultrasound. Of those without shoulder pain, 17% also had tears! Risk factors for an increased for tearing of the rotator cuff include a history of trauma, the dominant arm (ie your right arm if you’re right handed), and increasing age.

In a review of radiologic studies of 2,553 shoulders, researchers found full-thickness rotator cuff tears in 11.75% and partial thickness tears in 18.49% of the subjects for a total of 30.24% having some degree of tearing. In this group, about 40% of tears were found in pain-free shoulders. The researchers concluded that rotator cuff tears are common and frequently asymptomatic.

Both of these studies support the necessity to FIRST consider the patient’s clinical presentation and then correlate that with the imaging results. In other words, the presence of a RC tear on an image (usually MRI or ultrasound) does NOT necessarily mean there is pain (and vise versa)!

So what other things could be causing the shoulder pain? There are many: impingement, tendonitis, bursitis, muscle strain, capsular (and other ligament) sprain, frozen shoulder, and osteoarthritis (the “wearing out” type). Also, rheumatoid arthritis, lupus, polymyalgia rheumatica and other autoimmune types of “arthropathies,” fibromyalgia, a herniated cervical disk, shoulder dislocations, whiplash injuries, and more!

Most importantly, we must NOT forget to include referred pain to the shoulder from an impaired heart (such as coronary heart disease or heart attack), lung, liver, or gall bladder as these problems commonly refer pain to the shoulder and may represent a MEDICAL EMERGENCY!
