Anatomy and Biomechanics
Gluteus Maximus
The Gluteus Maximus is a biarticular muscle acting as the primary hip extensor and an auxiliary knee extensor via the iliotibial tract. As a versatile force generator, it plays pivotal roles in kinetic chains involving locomotion, weight transfer, and torque generation.
General Function: Involved in hip extension, external rotation, and abduction. Biomechanically, it generates force vectors contributing to sagittal, coronal, and transverse plane movements.
Origin: Originates from the posterior gluteal line of the ilium, the dorsal surface of the sacrum and coccyx, and the sacrotuberous ligament, providing a broad attachment footprint for optimal force exertion.
Insertion: Inserts into the gluteal tuberosity of the femur and the iliotibial band, creating a complex line of pull that allows for multi-planar hip movements.
Innervation: Primarily innervated by the inferior gluteal nerve (L5-S2).
Clinical Significance: It is a key player in triple extension, vital for explosive activities and crucial in eccentric control during the gait cycle's stance phase.
Visual Cues of Dysfunction: Limited stride length, asymmetric pelvic tilting, and decreased ability in forceful hip extension tasks can signify dysfunction.
Gluteus Medius
The Gluteus Medius is a primary hip abductor and pelvic stabilizer. It's integral to frontal plane stability and operates as a dynamic stabilizer during single-limb support phases of locomotion.
General Function: Serves as a primary hip abductor while offering medial and lateral rotation depending on the position of the hip. Also acts as a pelvic stabilizer during dynamic movements.
Origin: The muscle originates from the external surface of the ilium, specifically between the anterior and posterior gluteal lines, offering a fulcrum for frontal plane movements.
Insertion: Inserts into the lateral surface of the greater trochanter of the femur, optimizing the lever arm for hip abduction.
Innervation: Supplied by the superior gluteal nerve (L4-S1).
Clinical Significance: Its dysfunction is often implicated in lumbo-pelvic-hip complex instability, contributing to pathomechanics such as anterior pelvic tilt and Trendelenburg gait.
Visual Cues of Dysfunction: Evident as a lateral pelvic drop during single-leg stance or walking, often indicative of compromised frontal plane stability.
Gluteus Maximus Release (MSR) Procedures
Step-by-step Instructions
These MSR procedures are demonstrated in the accompanying video.
Positioning: Patient in the side-lying position, involved side up.
Initial Setup: The Patient's knee is flexed for stability.
Technique: The practitioner utilizes their forearm for treatment.
Synchronization: Move the patient's knee rhythmically and slowly in sync with forearm treatment. Use the non-treatment hand to stabilize the patient's upper leg; keep this hand relaxed.
Pressure: Employ moderate compression via a combination of forearm supination and pronation.
Focus Area: When the practitioner encounters a restriction, slow down and spend adequate time on it until a release is felt.
Advanced Maneuver: Incorporate upper leg circumduction to induce shear stress, assisting in myofascial release.
Fiber Orientation: The Gluteus Maximus muscle fibers are obliquely oriented, running diagonally from the sacrum, ilium, and coccyx to the femur and iliotibial band.
MSR Demonstration Video
In this video, Dr. Abelson demonstrates Motion Specific Release (MSR) procedures for releasing the Gluteus Maximus and Gluteus Medius muscles.
Best Practices
Time Factor: Take your time with these procedures. The process of releasing myofascial restrictions cannot be rushed.
Circumduction Benefits: Employing circumduction in your MSR procedures offers neurophysiological advantages such as modulating nociceptive signals and fostering muscle relaxation. Furthermore, it has the added benefit of system-wide therapeutic intervention, aligning well with MSR's comprehensive treatment philosophy.
Kinetic Chains: Always consider the effects of a larger kinetic chain on the primary structures.
Precautions
Manual therapy on any structure requires careful consideration of underlying medical conditions, the patient's history, and current symptoms.
Precautions include avoiding therapy on inflamed or ruptured tissues, contraindicated medical conditions, and post-surgical cases without clearance.
Proper assessment, consent, and technique are crucial to minimize risks.
Gluteus Maximus Functional Kinetic Chains
Understanding kinetic chains is essential for MSK practitioners, offering a nuanced framework for precise diagnosis, effective treatment, and targeted rehabilitation through techniques like MSR. The framework includes:
Direct Myofascial Connections
Synergists
Stabilizers
Antagonists
Direct Myofascial Connections
These fibrous networks transmit force across muscles, linking them in a continuous chain. Disruptions in these connections can lead to impaired force transmission, affecting overall biomechanical efficiency. The Gluteus Maximus, a cornerstone in human movement and posture, has several direct myofascial connections that significantly influence its function and integration with other structures in the body. These connections can be categorized as follows:
Thoracolumbar Fascia: A strong, layered membrane that also engages with the erector spinae and latissimus dorsi.
Iliotibial Band (ITB): This lateral thickening of the fascia lata wraps around the thigh to the knee and serves as a connection to the tibia.
Sacrotuberous Ligament: Connects the sacrum to the ischial tuberosity, providing a base for the gluteus maximus to anchor to the pelvis.
Fascia Lata: A deep fascia layer covering the thigh, it offers a connection to the quadriceps and hamstrings.
Inferior Gluteal Fascia: Provides a myofascial connection between the gluteus maximus and other gluteal muscles like the gluteus medius and minimus.
Synergists
These muscles work together to facilitate specific movements, serving as the action's active agents. Synergistic dysfunction often leads to compensatory patterns, affecting the muscle group's overall performance.
Hamstrings (Biceps Femoris, Semitendinosus, Semimembranosus)
Gluteus Medius and Minimus
Piriformis and other external rotators
Adductor Magnus (posterior part)
Stabilizers
These muscles provide the foundational support during movement, ensuring efficiency and safety. Weak or inhibited stabilizers can compromise joint integrity, making movements less efficient and more prone to injury.
Erector Spinae
Quadratus Lumborum
Abdominal Muscles (Transverse and Oblique)
Antagonists
Working in opposition to the action, antagonists are essential for both concentric and eccentric muscle contractions. If dysfunctional, antagonists can decrease strength and create muscle imbalances, impacting the range of motion and potentially leading to injury.
Hip Flexors (Iliopsoas, Rectus Femoris)
Internal Hip Rotators (Tensor Fascia Latae, Anterior fibers of Gluteus Medius and Minimus)
Adductors
Gluteus Medius Release (MSR) Procedures
Step-by-step Instructions:
Note: These MSR procedures are demonstrated in the accompanying video.
Positioning: Situate the patient in a side-lying position, with the affected side facing upward.
Initial Setup: Flex the patient's knee to around 90 degrees to provide a stable base and minimize pelvic movement.
Technique: Utilize the forearm for the application of myofascial techniques, offering both breadth and depth in pressure.
Synchronization: Coordinate rhythmic knee movement with the forearm application, synchronizing the tempo for optimal tissue engagement. The non-treatment hand should lightly stabilize the patient's upper leg.
Pressure Application: Generate the therapeutic force through a combination of forearm supination and pronation, applying moderate compression without triggering pain or discomfort.
Focus Area: Upon identifying areas of myofascial restriction or trigger points, reduce speed and concentrate the technique, allowing time for tissue release.
Advanced Maneuver: Introduce upper leg circumduction to augment shear stress and facilitate the breakdown of myofascial adhesions.
Fiber Orientation: Be mindful that the Gluteus Medius has a multi-directional fiber arrangement. The anterior fibers assist in internal rotation and flexion, while the posterior fibers engage in external rotation and extension.

Stabilizers
Antagonists
Direct Myofascial Connections
These fibrous networks allow force to be transmitted across muscles, linking them in a continuous chain. A disruption in these connections can lead to impaired force transmission, affecting overall biomechanical efficiency. The Gluteus Medius, has a web of direct myofascial connections that impact its function and interaction with adjacent structures. Here are some of its key direct myofascial connections:
Iliac Fascia: This is the fascia covering the ilium, and the gluteus medius is deeply invested in it, facilitating a strong connection to the pelvis.
Gluteal Aponeurosis: This is a flat, fibrous sheet that acts as an extension of the iliac fascia, and it intimately connects the gluteus medius to the gluteus minimus and maximus.
Tensor Fascia Latae (TFL): This muscle shares the fascia lata and contributes to the iliotibial band (ITB), linking it functionally and myofascially with the gluteus medius.
Iliotibial Band (ITB): Although not as directly connected as it is with the gluteus maximus, the ITB indirectly influences the gluteus medius through its shared tension line via the TFL.
Superior Gluteal Nerve and Vessels: Not myofascial per se, but these neurovascular elements run deep to the gluteus medius, and their fascial encasements often interact with the muscle's fascia, impacting its function.
Synergists
These muscles work together to facilitate specific movements, serving as the action's active agents. Synergistic dysfunction often leads to compensatory patterns, affecting the muscle group's overall performance.
