What is a recommended practice to increase patient comfort during treatment?

Providing supports under the head, knees, and arms is a recommended practice for increasing patient comfort during treatment. This approach helps to properly position and stabilize the patient's body, reducing strain on muscles and joints, which can help alleviate discomfort during lengthy treatment sessions. Proper support is essential as it enhances patient relaxation and promotes a feeling of security, allowing for better tolerance of the procedure.

The other options do not prioritize patient comfort as effectively. Heavy blankets might provide warmth but can also feel restrictive or uncomfortable for some patients. Restricting movement with belts may create a sense of confinement, leading to anxiety rather than comfort. Lowering the treatment table could be beneficial for access or visibility but does not inherently address patient comfort during the treatment itself.
