Take Home Message: A single 5-minute compressive myofascial release treatment improved dorsiflexion range of motion more than instrument-assisted soft tissue mobilization.  
Insufficient ankle dorsiflexion range of motion predisposes healthy individuals to lower extremity injuries. Clinicians use compressive myofascial release (CMR) or instrument-assisted soft tissue mobilization (IASTM) to target myofascial lesions in the triceps surae that limit ankle flexibility. However, there is little evidence to determine which method may be better at improving ankle dorsiflexion. Therefore, Stanek and colleagues performed a randomized controlled trial to assess the short-term effects of a single 5-minute session of CMR or IASTM (Graston technique) on the triceps surae for improving closed-chain ankle dorsiflexion range of motion among physically active people. The authors measured pre- and post- ankle dorsiflexion range of motion in a standing and kneeling position. They randomized participants with less than 30º dorsiflexion and a Silfverskoild test positive for soft-tissue restriction to 1 of 3 groups: CMR, IASTM, or control group. A single clinician applied all CMR treatments, which began with shaking a muscle belly for 30 seconds, 1 minute focused on lateral and medial sides of Achilles tendon, and 2 minutes focused on the musculotendinous junction. The clinician applied broad strokes, distal to proximal, with knuckles or thumb positioned at 45º to the muscle. A separate examiner administered all IASTM treatments according to the M1 Basic Training course. Treatment began with a 1 minute scanning of the triceps surae, followed by 4 minutes of localized treatment in the areas of restriction. The authors found that CMR produced greater standing dorsiflexion improvements (4.8º) compared with IASTM (1.8º) and control (1.1º) groups. However, the CMR group (4.4º) was only better than the control group (-0.8º) when assessing dorsiflexion improvements with the kneeling assessment (IASTM: 3.1º).
Compressive myofascial release and IASTM are widely used and accepted soft tissue mobilization techniques. The IASTM cultivated a shift in clinical practice by reducing the stress placed on clinicians while performing myofascial release. However, it has eliminated the effect of human touch on mechanical and neurological responses by the patient. The authors acknowledge the CMR treatment took into consideration patient comfort levels when applying pressure. In contrast, the IASTM treatment session focused on appropriate pressure to eliminate an adverse inflammatory response. Perhaps the difference in applied pressure between the two treatment groups could explain the results of this study. Additionally, it is unlikely a clinician will only implement a single treatment session when addressing soft tissue restrictions of the triceps surae group. Clinicians should continually assess ankle range of motion to affirm deficits are present and due to muscular inflexibility and exclude any arthrokinematic restrictions. A discrepancy in dorsiflexion range of motion due to a malpositioned talus or fibula would not benefit from myofascial release therapy. If a clinician confirms that the limited dorsiflexion is attributable to muscular inflexibility, then it may be beneficial to use CMR to elicit immediate effects. Proper evaluation before and after interventions should be used to assure continual improvements are occurring.
Questions for Discussion: When applying CMR or IASTM, do you always take into consideration feedback from your patient or do you rely on your knowledge and experience to apply appropriate pressures? Which technique to you find to be most beneficial to your patients with myofascial restrictions? Do you assess osseous and soft tissue to determine cause of range of motion deficits?
