In which client would a back massage be contraindicated? A back massage would be contraindicated in clients with certain health conditions where massage could worsen their condition or pose a health risk. Some of these contraindications include acute inflammation, fever, infectious skin diseases, severe osteoporosis, uncontrolled hypertension, recent surgery or fractures, and certain cardiovascular conditions.
