Treatment Types Defined   Swedish Massage is the most popular "Western" massage that combines long strokes, kneading and friction techniques on muscles; increases circulation of the blood, lymph, and vital energy; relaxes muscles and calms the nervous system.  Shiatsu and Acupressure are "Eastern" massage forms using finger and thumb pressure on points of the body associated with the meridians to rebalance the body's energy.  Deep Tissue Massage uses slow strokes and firm pressure to release chronic tension patterns in connective tissue.  Pregnancy Massage comforts and relieves a pregnant woman's body. Special pregnancy tables allow the woman to lie face down.  Specific Injury Massage focuses the entire treatment on specific problem areas to promote recovery. Combined techniques like Swedish, deep tissue, and trigger point work are often used. Hot or cold packs may be applied.
