a neurological symptom characterized by involuntary resistance to passive movement of the limb. When the researcher tries to move the patient’s limb, the patient resists movement, often in a rigid or rigid manner. This phenomenon may be a sign of damage to the upper motor neuron or dysfunction of motor pathways in the brain or spinal cord. It is commonly found in conditions such as parkinsonism, hemiparesis, or other neurological disorders that affect motor control and reflexes. The presence of hegenhaltene can be used as part of a clinical evaluation to determine the location and extent of neurological damage.
