This list focuses on instrument-assisted methods of soft tissue treatment. What unites them is pseudoscience: the claimed mechanism of action or declared effect lacks sufficient evidence.
One clarification upfront: this is not a discussion of the absolute effectiveness of these methods. The question is framed differently — how much more effective is any given method compared to regular massage? This approach is justified by the fact that all of the methods listed are typically presented as superior to classical massage. That is their supposed value: a therapist learns the technique and gains what is claimed to be a more powerful tool for practice. The logic is straightforward: if a method genuinely delivers more than a skilled therapist can achieve with their hands — it works. If the effect is comparable to regular massage or lower — it’s marketing.
Group 1. IASTM
Historically, this group traces back to the Chinese technique of Gua Sha, known since antiquity. The claimed mechanism of action lacks scientific basis, and statistically confirmed effectiveness has not been demonstrated. Meanwhile, complications — most notably skin damage — are not uncommon.
Graston Technique is a trademarked method using specially designed steel instruments. It claims to reduce pain and affect the connective tissue of fascia, ligaments and tendons by breaking down so-called adhesions — the existence of which, as described, has not been confirmed by science.
ASTYM (Augmented Soft Tissue Manipulation) is a conceptually similar trademarked method with comparable claimed effects, distinguished by the use of plastic instruments. ASTYM proponents insist it is entirely independent from Graston. Both methods share an absence of convincing efficacy data alongside a notably high cost of both instrumentation and certification courses.
RockBlades is essentially a reincarnation of Graston Technique with a slightly different set of instruments but identical goals: the purported breakdown of adhesions. Notably, none of the methods listed above offers a valid diagnostic protocol for identifying these adhesions in the first place.
Group 2. Cupping Techniques
From the earliest instruments made from animal horn to modern glass and silicone cups, the history of cupping is rooted more in religious and ritual practice than in medicine. Over time, cupping gained some traction in clinical settings, but was largely abandoned due to insufficient evidence.
Contemporary methods can be broadly divided into static and dynamic. Among commercial systems, MediCupping and ACE Massage Cupping stand out — adaptations of cupping technique using electric or manual pumps to create negative pressure, marketed as complete systems with proprietary equipment and training programs.
It is worth emphasizing: cups as a tool for soft tissue treatment are entirely legitimate in their own right. Their mechanism is based on negative pressure, which produces specific sensory effects and adds variety to classic massage practice.
Pseudoscience lies not in the technique itself, but in the effects attributed to it. Claims that cupping can break down adhesions, separate fascial layers, or draw toxins out of tissues have no scientific basis.
Incorporating instruments into massage practice is both appropriate and beneficial. They reduce strain on the therapist’s hands, provide additional leverage to achieve the necessary force, and offer clients new sensory experiences. There is every reason to use a variety of instruments in massage practice — but without the mythological and pseudoscientific narratives that artificially inflate their value.
An instrument and the mythology surrounding it are not the same thing.
