We typically recommend 2–3 treatments a week. The total number of sessions will depend on the condition it is being used for, along with other health factors — every person’s health is different. For example, if a young healthy adult experiences a muscle tear (which is an acute condition) they would likely only require 2–3 laser treatments weekly for approximately 4 weeks. In contrast, an elderly patient with arthritis (a chronic condition) may require a complete treatment of up to 12 weeks or more.
