  • While stimulus threshold appears to be a useful quantitative metric of nerve dysfunction, there was not a statistically significant difference in the amplitude of muscle acceleration between compressed and non-compressed sides. Since increases in acceleration amplitude were previously reported following nerve root decompression in one clinical study (24), this metric was evaluated as a potential additional biomarker. There are several possible explanations for this negative result. First, compression neuropathy has been shown to be a primarily demyelinating process, independent of axonal damage in its initial stages (42, 43). Demyelination leads to exposure of the internodal membrane and an increase in the stimulation required for excitation (48), which explains the increase in MMG-st. However, MMG amplitude should be most sensitive to axonal loss, as this would decrease the number of motor units activated and decrease muscle acceleration. From a physiologic perspective, it is therefore reasonable to expect MMG-st to be more sensitive than acceleration amplitude for this nerve entrapment model. Second, variations in positioning and attachment of the accelerometer sensor on the rat may have introduced variability sufficient to obscure modest amplitude differences. The accelerometer sensor was around the same size as the rat hindlimb, limiting the precision of consistent placement in a way that could be less problematic in human patients. small but statistically Additionally, significant baseline differences in MMG-st and CMAP latency were observed between sides prior to any intervention. The directions are contradictory: MMG-st was slightly lower for the experimental nerves which would later undergo compression (suggesting a healthier nerve), while CMAP latency was higher (suggesting a less healthy nerve). The latency difference may have a systematic explanation related to temperature-dependent conduction velocity. We performed all procedures on the control side first to minimize the interval between electrophysiology studies on both sides, as the silicone tube placement/removal on the experimental side was the most this ordering may have time-consuming element. However, introduced a systematic bias, as core temperature likely decreased between measurements. Assuming a 3 C drop (49), 40 mm nerve length, 50 m/s baseline conduction velocity, and a temperature C (50), the expected latency increase is coefficient of 2.8 m/s/ 0.16 ms, essentially equal to the observed baseline difference. However, temperature does not explain the lower MMG-st on the experimental side, as decreasing temperature should increase stimulation threshold (51). The baseline difference in MMG-st most likely reflected natural side-to-side variability that reached marginal significance (p = 0.045) given the large pooled sample. Even if the difference was due to some unknown systematic bias, this would mean that the effect size observed in MMG-st following compression would be an overly conservative estimate. Importantly, post-compression changes in both measures far exceed these small baseline differences, and they are unlikely to meaningfully affect the primary conclusions. ◦ ◦ A limitation of the MMG devices tested was inability to measure latency, which would be expected to be increased due to nerve compression. Our device operated at a sampling rate of 200 Hz, corresponding to a sampling period of 5 ms. Over such a short propagation distance (∼50 mm) in the rat model, this did not provide enough temporal resolution to monitor increased latency due to compression. This limitation could be resolved in future work by upgrading the hardware and processing pipeline to allow for increased sampling frequency, and this would be less problematic in humans due to longer nerve lengths. Aspects of the experimental design could be improved for future studies. The intention of testing varying entrapment duration was to analyze worsening severity over time (39). While the 2-month cohort did appear to be less severely affected based on MMG and histomorphometry, from 3 months onward there was no clear worsening. There were 4 animals in the 6-month cohort which experienced severe nerve compression; while this may have been exacerbated by the long duration, we believe this was primarily due to a deviation from protocol in which the sutures around the silicone tube were overtightened. This does suggest an alternative future approach for testing varying entrapment severity by using tubes of varying internal diameter.

  • The cross-correlation coefficient ultrasound analysis demonstrated enhanced myofascial gliding in the flossed leg, but the study did not examine whether improved fascial gliding correlates with reduced injury risk or specific running economy metrics in distance runners.

  • The study proposed that reperfusion response following release of the floss band may increase norepinephrine levels and maintain reactive strength index (RSI), but this physiological mechanism was not directly measured. Future studies should directly quantify circulating growth hormone and norepinephrine levels before and after fascial flossing to validate the proposed reperfusion-mediated performance maintenance mechanism.

  • The sample was limited to male collegiate long-distance runners; sex-related differences in tendon stiffness and hysteresis have been previously documented, suggesting fascial flossing effects may differ in female athletes.

  • A limitation for device use is the cost and accessibility. Foam rollers and basic massage tools are cheap and widely available. In contrast, high-quality massage guns can be expensive, and shockwave machines are very costly and thus limited to clinics with those resources. Additionally, certain devices require expertise to use correctly (Kerautret et al., 2020). Shockwave requires knowledge of proper dosages and locations. Massage guns also come with contraindications such as not using over nerves, bony areas, or sensitive tissues (Ferreira et al., 2023). Thus, training and guidelines are important to prevent misuse. Generally, with reasonable use, these devices are safe. Device-mediated interventions further expand the delivery of fascial loading through self-applied and technology-assisted modalities. These approaches improve accessibility and support integration of fascial release within broader rehabilitation strategies.

  • Instrument-assisted techniques have a moderate evidence base. They appear effective for immediate improvements in flexibility or pain pressure thresholds. However, long-term functional improvements attributable solely to the instrument are harder to demonstrate. Despite these issues, IASTM continues to be widely used because it is relatively safe and often yields quick short-term results, which can motivate patients. Adverse effects are minor and mostly limited to transient soreness or superficial bruising. Proper training of the therapist or patient is important, as inappropriate technique (too aggressive, wrong angle) could cause tissue damage or unnecessary pain (Tang et al., 2025). Overall, instrument-assisted techniques enable more targeted and consistent mechanical loading of fascial tissues while reducing therapist strain. These methods extend the principles of manual release through enhanced mechanical precision and reproducibility. 5 Device-mediated fascial modulation: self-applied and clinician-operated systems These approaches include both core self-myofascial release methods and selected device-based interventions that influence myofascial tissue behavior through mechanical or acoustic stimulation. While not all device-based modalities constitute true myofascial release in the strict manual or instrument-assisted sense, they are included in this review where their clinical use, mechanical interaction, or proposed physiological mechanisms involve fascial tissue loading, fascial mechanoreceptor stimulation, or modulation of myofascial pain and mobility. This equipment ranges from simple foam rollers to advanced electro-mechanical instruments. These techniques often enable self-treatment by patients or enhance therapy through technology (Wiewelhove et al., 2019; Wuerfel et al., 2022; Michalak et al., 2024). The device-based approaches can be broadly classified into self-myofascial release (SMR) tools and clinician-applied devices. 5.1 Self-applied mechanical loading of fascial tissues 5.1.1 Foam rollers and roller massagers The most ubiquitous self-treatment device is a foam roller. Foam roller is firm, cylindrical roll with different densities used by individuals to apply body weight pressure to their muscles and fascia. Foam rolling technique is popular in fitness and rehabilitation communities as a method to perform myofascial release on oneself. It is often used as part of warm-up or cool- down routines (Zainuddin et al., 2025). Using a foam roller, a person can target large muscle groups (quadriceps, hamstrings, calves, iliotibial band, back muscles) by slowly rolling their body over the roller (Konrad et al., 2022). The pressure from the roller acts similarly to a massage or MFR from a therapist, but it is less targeted. The convenience and low cost of foam rollers have made them a staple in gyms and homes (Miller, 2024). Past studies generally supports short-term and immediate benefits of foam rolling. Systematic reviews have found that self- myofascial release (SMR) with foam roll or roller massager can increase joint range of motion acutely without detrimental effects on the performance of muscle (Martı́nez-Aranda et al., 2024). Cheatham et al. (2015) concluded that a brief session (1–2 minutes per muscle group) of foam rolling can lead to immediate improvements in flexibility. Additionally, when it is used after intense exercise, foam rolling appears to reduce muscle soreness and improve recovery markers (Cheatham et al., 2015). Athletes who foam roll after workouts report less delayed onset muscle soreness (DOMS) and a quicker return of muscle performance when they are compared to those who don’t (Scudamore et al., 2021). It is also notable that foam rolling does not seem to cause harm. Different studies consistently show it does not negatively impact muscle function, even when done before exercise. This has led to recommendations that foam rolling is a useful adjunct to warm-ups and to recovery protocols (Adamczyk et al., 2020). 5.1.2 Massage balls and therapy canes Other self-myofascial release tools include massage balls (like lacrosse balls or spiky balls). These are excellent for pinpoint release (e.g., into the gluteal muscles or shoulder blade area) (Ferreira et al., 2022). Also, therapy canes or hooks are considered a self-myofascial release tool. These are plastic cane-shaped tools that allow a person to apply pressure to hard-to-reach spots such as between the shoulder blades. These devices enable individuals to treat trigger points and tight fascia on their own. It is done application of sustained pressure until release is felt. Many physical therapists and trainers recommend these as part of home exercise programs. They are recommended so patients can manage their myofascial restrictions daily in between therapy sessions (Ferreira et al., 2022; Miller, 2024).
