In human anatomy, the lower limb is a part of the lower limb between the knee and the ankle. The thigh is between the waist and the knee and forms the remaining lower limbs. The term leg or "lower leg" is often used to describe all legs. This article generally follows general usage. Evolution provides two different features to the human body: specialization of the upper limb for visually guided operation, and development of lower limbs to a mechanism particularly suitable for effective bipedalism. The ability to stand up is not human-specific, but other primates can accomplish this with a large amount of energy consumption in a short time. However, human adaptation to bipedal walking affects not only the foot but also the position of the center of gravity of the body, reorganization of the internal organs, the shape and biological mechanism of the trunk.

Hemiplegial walking is usually seen as a result of stroke. The upper limbs are in a curved position and are inversed and rotated in the shoulder. Rotate the lower limbs inwards, extend the knees, invert the ankles, and bend the sole. Walking can be slowed down by hitchhiking of the surrounding limbs or hips to help clean the floor. Both legs walk.通常 is usually associated with the lower limbs. Contracture of the adductor muscle may form a "scissors" type walk with a narrow support base. The squat down at the bottom of the leg shows squatting as "walking" on the "tip" and often as a drag on the toes. Excessive waist and knee flexion are necessary to overcome this problem

Spinal anesthetic is used for surgery of the lower limbs and abdomen. It injects it on the waist and pierces the lower body. Epidural anesthesia is often used to alleviate the pain of childbirth or lower extremity surgery. Apply a small catheter around the spinal cord instead of an injection needle

Brain tumor or spinal cord tumor is a common cause of progressive progressive isolated limb progression slow. That person shows weakness of the leg, usually starting from the distal end of the foot, including proximal muscle groups, spreading over weeks to months. This is because the fibers of the lower limb are on the side of the spinal cord. If you have back pain or root aches, you may be a spinal cord injury, possibly a tumor. In addition to weakness of exercise, examination may indicate a loss of sensation in the affected feet. Unilateral lower extremity weakness, bladder symptoms are not common. Diagnosis is almost always late in the case of tumor spinal cord compression when the patient has unilateral leg weakness. However, even without sensory levels, it is necessary to doubt spinal cord compression because 23% of cases may show unilateral weakness.

Introduction Emergency and hemiplegia are common neurological symptoms in emergency and outpatients.
