[EX Q]: [header] How to use dance movement therapy [title] Find a certified dance therapist. [step] Search for a therapist who is qualified to provide dance and movement therapy. The person should be a registered dance therapist. <sep> (A) Three-dimensional and dynamic dance therapy will be hard for a dance therapist to follow. Asking for a referral can take several months and is expensive. (B) If you are not employed or licensed, you may qualify for regular sessions with her or him. If you work at a dance studio, you might want to consider a person with a dance degree through the national dance accreditation council (a&r) or the accreditation (tacp) commission on dance activity therapy. (C) This means they've completed extensive training in clinical work using dance therapy and can provide high quality care. [substeps] You may find a dance therapist through a program at a local hospital or at a therapy clinic. (D) There are other career paths than dance therapy, like dance or music therapy, but these do require evaluation by an independent therapist.

[EX Q]: [header] How to exercise to prevent blood clots [title] Get up and move around. [step] Whether you're traveling by train, plane, or automobile, long-distance travel involves a lot of sitting. When you sit, you decrease circulation in your legs-especially if you sit with your legs crossed or with one foot under you. <sep> (A) If you are on a train or coach, the seat underneath you always feels flat, as if you are sitting. While there are good ways to stretch out your legs, there is not a lot a group of people can do. (B) This will help promote blood circulation to your feet. It will also keep you from rubbing your legs in an annoying manner-you can't promote blood flow when you're sitting on one leg. (C) [substeps] You can exercise while you drive or driving, although getting up and down on the exercise train can significantly improve circulation. You can also listen to music while you exercise, which will also help to prevent blood clots. (D) [substeps] If you're on a plane, try to get an aisle seat so you can get up and move around more easily. Ideally, you want to get up and stretch your legs or walk up and down the aisle once every hour or so.
