A massage modality is a system of techniques or a particular approach to massage to achieve certain outcomes. A modality is usually developed in a certain region or sometimes by a particular person. Some modalities are comprehensive, meaning that they are intended to serve as the sole framework for the massage session. Other modalities are techniques that are intended to be used in conjunction with other types of massage or during a general Swedish style massage. Below are a list of massage modalities/techniques that I have had some experience with. Some I have used extensively and others I have only had limited, informal experience. Unless you have had experience with one of the below modalities, please research them (youtube, google, even an image search might be helpful) before asking for me to incorporate them into your session.
Swedish: this is the type of massage most western clients are familiar with.
Deep tissue: not necessarily a modality, just the depth of tissue the massage techniques are aimed to address
Reflexology/acupressure
Craniosacral
Myofascial Therapy
Trigger Point Therapy
Cupping
Hot stones (I don't do whole body hot stone massages, I only use them briefly on the upper back and neck)
Muscle scraping
Manual lymphatic drainage
Stretching/Traction/Pin and stretch
Aromatherapy (not really a modality, just using essential oils to help bring about a conducive state of mind)
