Perception of Touch
Touch is an important communication channel for humans that is key to manual therapy. Several studies have demonstrated that the stimulation of sensory/afferent touch fibers activates specific brain areas in the person (subject/client) receiving the touch stimulus. We also know thatthe activation pattern of our central nervous system is influenced by the attention that we pay while receiving the touch.
Perceiving the Intention of Touch
Beyond this, personal experience suggests that when we receive a massage, a pleasant caress, a pat on the back, or a handshake, that we can also perceive the emotional state of the person (touch giver / therapist) who is giving the touch. However, no research has actually investigated the effect on the person’s / client’s brain by the intention of the therapist who is giving the touch.
Study – Mindful Touch versus Non-Mindful Touch
Thus, a study from Chieti, Italy, investigated brain connectivity while clients were receiving a static touch by a touch giver who was focused on either the touch that they were giving (in other words, they were practicing “mindful touch”) or a sound that they were hearing while giving the touch (in other words, practicing “non-mindful touch”).
The study was a randomized-controlled single-blinded study with 40 healthy right-handed adult participants. The effect of touch on the client’s brain was monitored using functional magnetic resonance imaging (fMRI).
The clients were randomly assigned to one of the two touch treatment groups:
- Therapist focusing on tactile perception from the hands (mindful touch group)
- Therapist focusing on auditory stimuli (non-mindful touch group / sound focused group).
Mindful Touch Group
The therapists in the mindful touch group were asked to focus their attention on the feeling/perception from the hands that were contacting the client, i.e., the therapist had to feel the client’s tissue regarding its consistency, density, temperature, responsiveness, and motility (e.g., myofascial movements).
Non-Mindful Touch Group
The therapists in the sound-focused (non-mindful touch) group were asked to direct their attention toward acoustic stimuli (beeps) that were delivered through headphones. These beeps were deliveredat a random interval between 0.5 seconds and 2.0 seconds; and the therapist had to count the number of beeps per session.
Digital COMT
Did you know that Digital COMT (Digital Clinical Orthopedic Manual Therapy), Dr. Joe Muscolino’s continuing education video streaming subscription service for massage therapists (and all manual therapists and movement professionals), has at present (December of 2018) more than 1,000 video lessons on manual therapy continuing education, including entire folders on massage therapy, stretching, and joint mobilization. And we add seven (7) new videos lessons each and every week! And nothing ever goes away. There are also folders on Pathomechanics and Anatomy and Physiology, including an entire folder on Cadaver Anatomy… and many, many more on other manual and movement therapy assessment and treatment techniques?

Results
The results revealed that sustained static touch applied by a therapist resulted in significant differences in brain activity of the person receiving the touch depending on whether the person giving the touch was focused on the touch or focused instead of random beeping sounds (these changes were noted in connectivity between regions of the clients’ brains known as the posterior cingulate cortex, insula, and inferior-frontal gyrus). In other words, the perception and connective association of the client’s brain to the effect of touch by a therapist can be strongly affected by whether the therapist is engaged in mindful touch or non-mindful touch.
Comment by Joseph E. Muscolino
In one sense, the outcome of this study is somewhat intuitively obvious. That is that a client would experience differently a treatment that is given by a therapist who is performing a mindful massage versus a therapist who is performing a non-mindful massage. Having said that, it is nice to confirm our intuitive feelings. And it is gratifying to begin to qualify and quantify exactly where in the nervous system we experience these differences.
But the practical implications are clear: clients can tell the difference between the massage of a therapist who is mindful, present, and connected, and the massage of a therapist who is distracted and delivering pro-forma, cookbook, mediocre massage. This should serve as a wakeup call to therapists. I am sure that we all aspire to be the best therapists we can be, both for the benefit of our clients and for the benefit of our practice. And this requires being present and delivering to our clients the quality mindful touch that they deserve to receive and that we as professionals should have the integrity to give!
