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.

Trigger points in the gluteus medius muscle
The gluteus medius muscle plays an important role in hip and pelvic stability. It originates on the gluteal surface of the ilium, deep to the gluteus Maximus. It inserts on the greater trochanter of the femur. It’s main actions are to abduct the hip and to assist in internal rotation of the hip. It also maintains pelvic stability during walking and running. Trigger points in this muscle will refer pain into the sacrum, the iliac crest, and down the lateral hip and into the thigh. This muscle is often a cause of lower pack pain.
Trigger points in the gluteus Maximus
The gluteus Maximus is the buttock muscle. It originates on the gluteal surface of the ilium, lumbar fascia, sacrum and sacrotuberous ligament. It inserts on the gluteal tuberosity of the femur and the iliotibial tract. Extension and lateral rotation of the hip are it’s main actions. This muscle is heavily involved in activities like ice skating and is a common area to develops trigger points. When trigger points do develop they can refer pain in a crescent pattern from the gluteal fold to the sacrum. Trigger points can also refer pain deep into the buttock itself making it feel like other deeper muscles are involved. These symptoms can sometimes be mistaken for s.i. Joint problems. 
Trigger points in the supraspinatus
The supraspinatus is a muscle of the rotator cuff. Is sits above the infraspinatus and originates on the supraspinous fossa of the scapula. It’s insertion point is the superior facet of the greater tubercle of the humerus. It’s main function is to abduct the arm at the glenohumeral joint working with the deltoid. All rotator cuff muscles act to secure and support the head of the humerus in the glenoid fossa during arm movements acting as a sling. This muscle often gets impinged during overhead movements such as painting a ceiling. When trigger points form in this muscle they primarily refer a deep achy pain into the mid deltoid area with spillover pain radiating down the arm into the elbow.
Can Chiro help me?
Chiropractic is the most widely accepted and most frequently used type of “alternative” healthcare in the United States. This is largely due to the fact that it works, and because of that, there has been a steady increase in acceptance by the public, third-party payers, and the Federal government. Since the mid-1990s, a number of outside (non-chiropractic) observers have suggested that chiropractic has now entered mainstream healthcare.
One can position chiropractic as being BOTH alternative and mainstream. It is “alternative” since it approaches healthcare from an entirely different direction compared to the primary care medical profession. Chiropractic is non-surgical and promotes diet and nutritional approaches vs. drugs and surgery. Chiropractic is also arguably “mainstream” as it has evolved into a strongly utilized form of primary care through popular acceptance and utilization by the public.
So, what role does chiropractic play in today’s health delivery system? This question is still being debated, but there appears to be three camps: 1) Specialist—limited to musculoskeletal (MSK) complaints on an interdisciplinary primary healthcare team; 2) Primary healthcare “gatekeepers” that focus on ambulatory MSK complaints; 3) Generalist primary healthcare provider of “alternative or complementary” medicine that manage and/or co-manage both MSK AND non-MSK conditions.
Looking at this from the patient or “consumer” perspective, chiropractic already plays an important role in the healthcare delivery for many patients. In 1993, a report claimed 7% of American adults had received chiropractic care during the prior year. According to a 2015 Gallup poll (that included 5,442 adults, aged 18+, surveyed between 2/16/15 and 5/6/15) entitled, Majority in U.S. Say Chiropractic Works for Neck, Back Pain, “Chiropractic care has a positive reputation among many US adults for effective treatment of neck and back pain, with about six in 10 adults either strongly agreeing (23%) or agreeing somewhat (38%) that chiropractors are effective at treating these types of pain.”
The “highlights” from this Gallup poll include: 1) Two-thirds say chiropractic is effective for neck and back pain. 2) Many adults say chiropractors think of the patient’s best interest. 3) More than 33 million adults in the United States (US) saw a chiropractor in the twelve months before the survey was conducted. That means roughly 14% of U.S. adults saw a chiropractor in the 12 months prior to the survey (vs. 7% in 1993). An additional 12% who responded to the Gallup pollsters saw a chiropractor in the last five years but not in the last 12 months. Overall, 51% of those polled had previously seen a chiropractor.
Whether or not you have personally utilized chiropractic, the educational process, licensing requirements, public interest, third-party payer systems, and interprofessional cooperation ALL support firm ground for which you can comfortably and confidently seek chiropractic care for your complaints.

Trigger points in the infraspinatus
The infraspinatus muscle is one of the muscles that makes up the rotator cuff. It originates on the infraspinous fossa of the scapula, and inserts on the middle facet of the greater tubercle of the humerus. It functions to externally rotate the humerus and to stabilize the head of the humerus in the glenoid cavity during upward movement of the arm. Trigger points in this muscle refer pain deep into the anterior shoulder joint and down the anterior arm. Trigger points near the lower medial border refer pain into the rhomboids. This muscle is often injured during throwing motions.
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….
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.
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
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.
