A single movement can reveal the story hidden deep in the spine. Lasègue’s test stretches the sciatic nerve, tracing pain from the lower back down the leg—often pointing to a trapped root or a herniated disk at L4–L5. What looks simple is actually a powerful window into the body’s wiring, showing how one irritated nerve can change the way the entire leg feels

Yin deficiency. Your tongue is telling you something.

Every nerve root tells a different story. From L4 to S5, each level controls its own pattern of movement, reflex, and sensation in the leg. A weak ankle lift, a missing reflex, or a numb strip of skin can point directly to the exact spinal level affected. This map of the lower body’s neurology shows how precisely the spine communicates with the legs — proving that even the smallest change in a nerve can shift the entire function of the limb.

This diagram traces the sciatic nerve from its origin deep in the hip to its branches in the lower leg and foot. The highlighted areas show where pain often travels when the nerve is compressed — starting in the lower back or hip, then shooting down the entire leg. It’s a reminder of how one irritated nerve can create a burning, sharp, or electric pain pathway all the way to the toes. The sciatic nerve is the body’s longest and one of its most powerful, carrying both strength and sensation through every step we take.

NOTE THE HAMSTRING ANATOMY ✍️

✅ The hamstrings are a group of three muscles on the posterior (back) of the thigh: the biceps femoris, semitendinosus, and semimembranosus. They originate from the "sitting bone" or ischial tuberosity and extend across both the hip and knee joints, allowing for actions like flexing the knee and extending the hip.

✅ Hamstring muscles
Biceps femoris: Located on the outside of the back of the thigh, it has a long head and a short head.
Semitendinosus: Found in the middle of the back of the thigh, between the semimembranosus and biceps femoris.
Semimembranosus: The most medial and deepest of the three muscles, located on the inner side of the back of the thigh.

✅ Anatomical features
Origin: The semimembranosus, semitendinosus, and the long head of the biceps femoris all originate from the ischial tuberosity (the "sitting bone"). The short head of the biceps femoris originates from the femur.
Joints crossed: All three hamstring muscles cross both the hip and the knee joints.

✅ Function
They are crucial for movements like walking, running, and climbing, as they extend the hip and flex the knee.

✅ Clinical relevance
The hamstrings are a common site for injury, especially in athletes, due to their role in movement and the stress they endure.

THE OBTURATOR NERVE ✍️.

The obturator nerve originates from the lumbar plexus (L2-L4) inside the psoas major muscle, emerges from its medial border, and runs along the lateral wall of the pelvis.

It then passes through the obturator canal to enter the thigh, where it divides into anterior and posterior branches that innervate the adductor muscles of the medial thigh and provide sensory innervation to the skin and joints of the area.

NOTE THE ANATOMY OF PSOAS MUSCLE ✍️.

✅ The psoas muscle is a long, deep muscle that runs from the lower back to the groin and is a primary hip flexor. It is crucial for movements like walking, running, and standing, and it connects the spine to the legs, helping to stabilize the back and pelvis. The psoas can be a source of lower back, hip, or groin pain when strained or tight, a condition often referred to as psoas syndrome.

✅ Anatomy
The psoas muscle is located on each side of the spine, originating from the lumbar vertebrae and crossing the pelvis.
It combines with the iliacus muscle to form the iliopsoas muscle group, which inserts into the upper thigh bone (femur).
This muscle is long and can be around 16 inches in length in most adults, with a shape that is thinner at the top and wider at the bottom.

✅ Function
Hip flexion: The primary function is to lift your knee towards your chest, or to bend at the waist.
Posture and stability: It plays a vital role in maintaining posture and stabilizing the spine.
Trunk rotation: It also assists in rotating the trunk.

👉(A) Ideal lumbar posture and lumbar lordosis associated with a normal length of the psoas and lumbar erector spinae and

👉(B) altered biomechanical alignment of stance associated with tightness of the anterior hip capsule and iliopsoas. Under normal conditions, alignment of the acetabulum and femoral head is such that compression and shear stresses are optimally distributed protecting the hyaline cartilage and subchondral bone. Moreover, resting muscle tonus is balanced between hip flexors and extensors in a way that the metabolic cost to maintain balance is minimized. With plastic shortening of the anterior hip capsule and hip flexor muscles, more energy, i.e., activation of hip extensors, is needed to control a “quiet” bipedal stance. Increased isometric muscle activation simultaneously increases joint compression stress, which is poorly distributed because of the misalignment of the acetabulum and femoral head secondary to a chronic hip flexion pose.
