Massage therapy can include the use of what types of additional aids?

The correct choice highlights that massage therapy often employs a variety of tools and aids to enhance the effectiveness of treatment and improve client comfort. Using oil, lubricants, and heat lamps can significantly increase the smoothness of strokes during a massage, minimize friction, and provide warmth that relaxes muscles and improves circulation.

Oil and lubricants help facilitate movement over the skin, allowing the therapist to perform various techniques more effectively and comfortably. Heat lamps can be employed to soothe sore muscles, increase local circulation, and create a more pleasurable experience for the client.

The other choices are more restrictive, limiting the types of aids that can be used in massage therapy. For instance, herbal remedies and portable massage chairs may have their specific applications but do not encompass the broader range of beneficial tools, such as oils and heat sources, that are more commonly integrated into massage practice. Additionally, restricting the aids to only forms of electricity overlooks various non-electrical methods that are extremely valuable in a therapeutic setting. Thus, the inclusion of oil, lubricants, and heat lamps represents a more comprehensive understanding of the tools available to massage therapists.
