In a scalp massage, effleurage is characterized by which of the following movements?

Effleurage is a specific type of massage technique that involves smooth, gliding strokes. This method is gentle and typically performed using the palms or fingertips in a rhythmic manner, allowing for relaxation and an overall soothing effect. The stroking and circular hand movements used in effleurage help to stimulate blood circulation and promote a sense of calm.

This technique contrasts with the other options provided. The quick tapping of the scalp is more associated with techniques like tapotement, which focuses on rapid, percussive movements to energize the scalp. Deep kneading with finger pressure refers to petrissage, which involves lifting and squeezing muscles, and is generally more intense than effleurage. Finally, vibrating motions with electric devices are a distinct type of treatment that utilizes technology to create vibrations rather than the natural movements used in effleurage. Thus, the choice reflecting stroking and circular movements aligns perfectly with the characteristics and objectives of effleurage.
