These 16 therapies include deep tissue, chop, knock, kneading, stroke, acupuncture, butterfly, effleurage, sports mode, thai, swedish, pulsing, reflexology, assorted, auricular massage, and trigger point. Each massage therapy can be set to a specific intensity level from soft to strong (1-20) giving you the flexibility to design a pain relief treatment targeting your particular ailment. A convenient 60 minute timer can be set for your therapy session with increments of 10 minutes. Ultra 1610 features a easy-to-read backlit LCD display showing the active therapy, duration(timer), intensity level, lock indicator, and battery level.
