Correct Answer: hearing
spastic cerebral palsy is a neurological disorder that affects movement and muscle tone, primarily causing muscular stiffness and coordination difficulties. it is the most common type of cerebral palsy, which is a group of permanent movement disorders that appear in early childhood.
in individuals with spastic cerebral palsy, the brain's ability to control muscle movement is impaired due to damage to or abnormalities in the parts of the brain that control muscle movements. this results in involuntary contractions and an inability to relax the muscles, leading to stiff or tight muscles and exaggerated reflexes. these symptoms can make voluntary movements jerky or awkward.
consequently, a person with spastic cerebral palsy might face challenges with certain physical activities such as:
- **walking**: muscle stiffness in the legs and poor coordination can severely impact the ability to walk, often necessitating the use of mobility aids.
- **talking**: spastic cerebral palsy can affect the muscles around the mouth and jaw, making speech production difficult.
- **writing**: fine motor control is often impaired, which affects the ability to manipulate writing instruments.
however, spastic cerebral palsy generally does not affect auditory functions. hearing involves different pathways and structures within the brain and ears that are typically not impacted by the motor control issues associated with this form of cerebral palsy. therefore, hearing is not usually impaired in individuals with spastic cerebral palsy, and they are typically able to hear normally unless there is a separate unrelated condition affecting their hearing.
thus, in the context of the question, a person with spastic cerebral palsy might have trouble with walking, talking, and writing due to the implications of the disorder on muscle control and coordination. however, they would not generally have trouble with hearing as this sensory ability is not impacted by the motor control issues central to spastic cerebral palsy.
