The gluteus minimus is a small but important muscle that lies deep to the gluteus medius. It originates on the gluteal surface of the ilium, and attaches on the greater trochanter of the femur. It’s main actions are to abduct and medically rotate the hip. Trigger points in this muscle refer pain into the buttock and down the lateral and posterior leg, mimicking sciatica. This muscle should be the first to be examined if a straight leg test turns out negative. 
Knee Pain
Osgood Schlatter’s Disease
Children and adolescents have soft “growth plates,” which are areas where their bone is still growing. In children, this growth plate is much weaker than in adults. This means that children are more likely to suffer growth plate injuries than adults, especially during periods of rapid growth.
Osgood Schlatter’s disease, also called tibial epiphysitis, is a painful irritation of the growth plate near the insertion of your quadriceps muscle on your knee. The powerful thigh muscles attach onto your knee through the patellar tendon. When your thigh muscle contracts- like during running or jumping, they place a sheer force on the growth plate of your knee.
Osgood Schlatter’s disease is more common in athletes, particularly those who participate in soccer, gymnastics, basketball, running or track. It is most common between the ages of 10 and 15 and is relatively equally common between boys and girls. Excessively tight thigh or calf muscles may contribute to this problem.
You may experience pain with activity that requires running or jumping. You will often feel tenderness or even bony enlargement of your “tibial tuberosity”, just below your knee. Kneeling or prolonged squatting may be painful.
Some athletes with mild cases may continue activity as long as it does not increase your symptoms. Most cases may require a period of rest to allow the condition to heal. Depending on the severity of your condition, you may need to limit activities that require running and jumping for a while, usually two to eight weeks. You can often cross train in the pool or on a stationary bike.
You should avoid running with a narrow stride “on a line,” as this may increase your symptoms. Our office may recommend use of a patellar tendon strap to assist with your healing. Osgood Schlatter’s disease can temporarily limit your activity, but most of the time, it can be successfully managed, allowing your return to pain-free activity in a relatively short period of time.
Knee Arthritis; Who, Where, Why and How?
The bones in your knee have a slick protective covering called “cartilage” on the joint surfaces that touch each other. This cartilage serves as a friction reducer and shock absorber, thereby helping to extend the life of your joints. “Arthritis” means that your cartilage has begun to thin or crack and may eventually wear away, leading to a painful “bone on bone” situation.
Knee arthritis is very common, affecting more than 1/3 of adults over age 65. People who are overweight or have a history of knee injury or surgery are more likely to develop arthritis. Jobs and activities that require repetitive squatting, kneeling, pivoting or stair climbing may cause increased wear. Contrary to popular opinion, runners have no increased risk of developing knee arthritis. Women are two to three times more likely to develop knee arthritis as compared to men.
The pain of knee arthritis is often described as a “deep ache” that is aggravated by activity and relieved by rest. You probably notice morning stiffness that goes away after a short period of activity, but returns after sitting for long periods of time. Some patients have difficulty squatting, bending and walking stairs. You may notice that your knees pop and crack. Eventually, knee arthritis can cause you to walk slower, lose your balance and even fall more often. Many patients notice that their symptoms increase with weather changes.
Although there is no cure for the irreversible wearing associated with arthritis, there is help for your symptoms. Performing your home exercises is very important. The way that your knee is aligned (and wears) is largely based upon how your hip and foot function, so many of your home exercises will target those regions. Our office may prescribe arch supports or orthotics, since people with flat feet are almost twice as likely to suffer from knee arthritis.
Overweight patients should begin or increase low-impact aerobic exercises like walking, stationary cycling, elliptical exercising, water walking or swimming. Be sure to take frequent breaks from prolonged sitting and avoid overly painful activities.
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.
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. 
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.
Snapping Hip. Not as horrific as it sounds.
The muscle responsible for flexing your hip toward your trunk, is called the Psoas. This muscle begins on your lower spine and passes through your pelvis to attach onto the top of your femur (thigh bone). Along this course, the muscle travels across the front of your hip socket and over several bony prominences. If the muscle is too tight, its tendon may rub over these “bumps”. This occasionally produces an audible snapping sound, hence the moniker, “snapping hip”, aka “psoas tendinopathy”.
The tendon can be irritated by an acute injury, but more commonly from overuse- particularly repeatedly flexing your hip toward your trunk. The condition is also known as “dancer’s hip” or “jumper’s hip”, as movements associated with these activities are known culprits. Likewise, the condition is frequently seen in athletes who participate in rowing, track and field, hurdling, running (especially uphill), soccer, and gymnastics.
Your symptoms may include a “snapping” sound or sensation when you flex and extend your hip- although many cases are silent. Repeated rubbing causes inflammation and subsequent deep groin pain that can radiate to the front of your hip or thigh. Long-standing problems can trigger weakness or even limping.
The diagnosis of snapping hip is frequently overlooked. In fact, some studies show that identification is often delayed more than two years, while other potential causes are pursued. Fortunately, your problem has been recognized, and our office has several treatments to help you recover.
Psoas problems often start when one group of muscles is too tight, while another is too loose. Your home exercises will help to correct this problem. Depending upon the severity of your condition, you may need to avoid certain activities for a while. You should especially avoid repetitive hip flexion. Prolonged seated positions can encourage shortening of your hip flexors so be sure to take frequent breaks. Patients with fallen arches may benefit from arch supports.
What to expect with a trigger point massage.
A treatment with Bryan is very user friendly. And, no, you don’t have to remove any clothing. However, bringing a t-shirt and a pair of shorts or sweats is recommended.
The first time you come for a treatment you will be asked to fill out a Client History form. Bryan will go over the information you provide, asking for more detail and discussing the type of pain you are having and its location.
The treatment itself involves locating the Trigger Points in the muscle or soft tissue and applying a deep focused pressure to the Point. This will reproduce the pain and the referral pattern that is characteristic of that pain.
The treatment will be uncomfortable at first, but as the Trigger Points release, the pain will decrease. The pressure will always be adjusted to your tolerance level. If, at any time, you feel too uncomfortable you can ask Bryan to ease off a bit.
Depending on your specific problem, Bryan may also use some stretching and / or range-of-motion techniques, as needed.
After treatment, it is usually recommended that the client apply moist heat to the area treated.
Our Condition of the Month: ITB Syndrome
Iliotibial Band Syndrome
Your iliotibial band is a fibrous band of tissue running from the crest of your hip, down to your knee. A muscle near the crest of your hip called the tensor fascia lata, attaches to this band to help control movements of your leg. Your iliotibial band passes over the point of your hip and over another bony bump on the outside of your knee called the lateral epicondyle. When the band is too tight, it can become painfully inflamed as it repeatedly rubs over the top of either of these bony projections. Irritation at the bony bump near the knee is called iliotibial band friction syndrome.
The condition usually presents as pain on the outside of your knee that becomes worse with repetitive knee flexion or extension. This condition is the leading cause of lateral knee pain in runners, especially slower “joggers.” The pain usually develops 10-15 minutes into the workout. You may sometimes feel or hear a click during movement. Symptoms generally ease at rest. Running on slick “wintry” surfaces may aggravate the condition. Excessively worn running shoes may be a culprit.
This problem is commonly caused by weakness in your gluteal muscles. When these muscles are weak, the muscle that attaches to your iliotibial band must contract harder to stabilize your hip. Having one leg longer than another is a known aggravating factor.
Runners should minimize downhill running and avoid running on a banked surface like the crown of a road or indoor track, as well as wet or icy surfaces. Runners should reverse directions on a circular track at least each mile. Bicyclists may need to adjust seat height and avoid “toe in” pedal positions. Avoid using stair climbers or performing squats and dead lifts. Sports cream and home ice massage may provide some relief of symptoms.
