Which complementary therapy is characterized by transferring energy from the practitioner to the client to enhance well-being?

Choice A reason: Pseudoparkinsonism typically manifests as motor slowing, also known as bradykinesia, along with muscle rigidity, a shuffling gait, and resting tremors. While it is an extrapyramidal side effect of antipsychotics, it presents with a lack of movement rather than the hyperactive restlessness described in the scenario.

Choice B reason: Acute dystonia involves sudden, involuntary, and often painful muscle contractions, frequently affecting the neck (torticollis), eyes (oculogyric crisis), or tongue. It usually occurs within the first few days of starting medication and is characterized by rigid posturing rather than the subjective need to move.

Choice C reason: Akathisia is a common extrapyramidal side effect characterized by a subjective feeling of inner restlessness and the objective inability to remain still. Patients often pace, rock back and forth, or tap their feet. It typically appears within days or weeks of initiating high-potency typical antipsychotics.

Choice D reason: Tardive dyskinesia is a late-onset movement disorder resulting from long-term antipsychotic use, usually occurring after months or years of treatment. It is characterized by repetitive, involuntary movements such as lip-smacking, tongue protrusion, or choreiform movements of the limbs, rather than acute restlessness.

Choice A reason: Atypical, or second-generation, antipsychotics have a lower affinity for D2 receptors in the nigrostriatal pathway and a higher affinity for serotonin receptors. This pharmacological profile significantly reduces the risk of extrapyramidal symptoms (EPS) compared to first-generation medications, making them the preferred strategy for patients prone to motor side effects.

Choice B reason: Adding more typical antipsychotics would exacerbate the blockade of dopamine receptors in the basal ganglia. Typical antipsychotics are the primary causative agents of EPS, and increasing the total burden of these medications would worsen muscle rigidity, tremors, and the risk of developing irreversible tardive dyskinesia for the patient.

Choice C reason: While monitoring blood levels is important for some psychiatric medications like lithium or clozapine, most typical antipsychotics do not have a well-defined "therapeutic window" for blood levels that prevents EPS. The occurrence of EPS is more closely tied to receptor occupancy percentages than to simple systemic serum concentrations.

Choice D reason: Increasing the dose of typical antipsychotics directly increases the occupancy of D2 receptors in the striatum. When occupancy exceeds 80%, the likelihood of EPS rises dramatically. Therefore, increasing the dose is the opposite of the required clinical strategy to manage or prevent the development of movement disorders.
