A 70-year-old female patient presents to the hospital with declining cognitive function, tremors, and rigidity. Upon assessment, the nursing team notes the presence of a shuffling gait and bradykinesia. Her medical history includes hypertension and hyperlipidemia. The healthcare provider suspects that the patient may have a neurodegenerative condition marked by the degeneration of dopaminergic neurons in the substantia nigra. This disease often leads to a characteristic '__________________' posture in which the patient has a stooped back and a forward-leaning head.
