Perpetuating factors may include prolonged immobility, tilting the pelvis by sitting on a wallet, postural distortions and unstable equilibrium when standing. Myofascial trigger points in the gluteus minimus muscle may be activated or perpetuated by sudden acute or repetitiveĬhronic overload, SI joint dysfunction, injection of medications into the muscle, and nerve root irritation. Trigger points harbored in the anterior fibers of the gluteus minimus can refer into the lower buttock, down the lateral aspect of the thigh, and then further into the fibular region of the leg where the peroneal muscles are found.Īctivation of Trigger Points (in the gluteus minimus muscle)

An analysis of the gluteus minimus muscle’s anatomy and trigger point pain referral patterns clarifies how the function of this thigh abductor helps keep the pelvis level during single limb weight bearing and hints at the potential for a spillover connection (or the satellite nature of gluteus minimus trigger points) by way of the peroneal muscle tendons that attach into the foot. The gluteus minimus can be easily overlooked, says David, since the referred pain from this muscle is felt so deep and remotely from the location of the trigger points. Nationally Certified Therapeutic Massage and Bodywork massage therapist David Kent writing on Pseudo-Sciatica and Gluteus Minimus Trigger Point s in a May of 2011 Massage Today issue. The discomfort may also interrupt their sleep if they roll onto the effected side. The referred pain from trigger points in the gluteus minimus may be constant in duration, severe in intensity and may cause the patient to limp when they walk. When the patient tries to balance on one limb, the pelvis falls on the side of the raised limb indicating a positive Trendelenburg sign. When the nerve is compromised due to trauma, disc involvement or other factors, the supporting action of these muscles are diminished. The superior gluteal nerve arises from L4 through S1 and innervates the gluteus minimus, gluteus medius and tensor fascia lata. Let’s first explore the possible symptoms arising from gluteus minimus (outer hip muscle) trigger points. The area of referred pain is often distant from the TrP.

These may include increased or reduced skin temperature, sweating or dryness. From it, localized pain is produced in a specific area with associated autonomic changes. Direct compression, stretching, or other sources of irritation such as accumulation of the toxic chemical byproducts of muscle metabolism, or lack of oxygen, will ignite the TrP.

They prevent full lengthening of the muscle and weaken it. The pain patterns thus produced are called myofascial pain syndromes.Īctive TrPs are always tender. They are characterized by taut fibrous bands, a twitch response when stimulated, and constant areas of referred pain. Trigger points (TrP) are foci of hyperirritability in muscle, fascia or ligaments (connecting bone to bone as in joints). Osteopath Richard Bachrach of the Center for Sports and Osteopathic Medicine explains.

Those hyper-irritable spots in muscles, that when pressed on often refer a sensation distant to the area of contact.

Have the outside edge/s of your feet (or has one individual foot) been feeling tingly, weak or painful, but you haven’t yet been able to pinpoint or name one particular activity or incident that you can attribute the bizarre pattern to?īefore this discussion gets underway, please allow me to brief you on the definition and general nature of trigger points, Are you experiencing hip pain that seems sometimes constant and excruciating, which causes a limp while walking, or problems while lying on your side at night, or perhaps difficulty rising from a chair and/or the inability to stand up straight?Īre you struggling with finding a stretching movement or change of position that succeeds in relieving the pain, or having trouble lying down comfortably and walking normally?
