ABSTRACT
The aim of the study is to control the effect of myofascial mobilization on flexibility values ââin young men. 23 young adult men, aged between 18 and 30 years (74.8 ± 9.8 kg; 1.74 ± 0.06 cm; 24.7 ± 3.0 kg/m2), participated in the study, separated into experimental and control groups. Participants of the experimental group received an instrument assisted soft-tissue mobilization (IASTM) session, bilateral, in the muscular region of the quadriceps femoris, hamstrings and triceps surae. The rectus femoris, vastus lateralis and medial, biceps femoris, semitendinosus, semimembranosus, gastrocnemius and soleus muscles were mobilized for a period of 60 seconds. In the control session, participants remained at rest for a period of 15 minutes. The flexibility assessments were performed pre- and- immediately, 24 hours, and 48 hours post-sessions of both groups. The myofascial mobilization session promoted percentage increases in flexibility significantly higher at 24 hours when compared to values ââimmediately after, 24 hours and 48 hours after the control session (P < 0.05). The percentage increases in flexibility 48 hours after the myofascial mobilization session were significantly greater when compared to values ââimmediately post and 24 hours after the control session (P < 0.05). The findings of the present study suggest that an instrument assisted soft-tissue mobilization (IASTM) session promotes increases in flexibility in young adults one and two days after the intervention.

O objetivo do presente estudo foi verificar o efeito da mobilização miofascial nos valores da flexibilidade em homens jovens. Participaram do estudo 23 homens adultos jovens, com idade entre 18 e 30 anos (74,8 ± 9,8 kg; 1,74 ± 0,06 cm; 24,7 ± 3,0 kg/m2), separados em grupo experimental e controle. Os participantes do grupo experimental receberam uma sessão mobilização miofascial assistida por instrumento (IASTM), bilateralmente, na região muscular do quadríceps femural, isquiotibiais e tríceps sural. Os músculos reto femural, vasto lateral e medial, bíceps femoral, semitendinoso, semimembranoso, gastrocnêmio e sóleo foram mobilizados por um período de 60 segundos. Na sessão controle, os participantes permaneceram em repouso por um período de 15 minutos. As avaliações da flexiblidade foram realizadas pré, imediatamente após, 24 horas e 48 horas após as sessões de ambos os grupos. A sessão de mobilização miofascial promoveu aumentos percentuais da flexibilidade 24 horas significativamente maiores quando comparado aos valores imediatamente pós, 24 horas e 48 horas da sessão controle (P < 0,05). Os aumentos percentuais da flexibilidade 48 horas após a sessão mobilização miofascial foram significativamente maiores quando comparado aos valores imediatamente pós e 24 horas da sessão controle (P < 0,05). Os achados do presente estudo sugerem que uma sessão de mobilização miofascial assistida por instrumento promove aumentos da flexibilidade em adultos jovens após um e dois dias à intervenção.(AU)
ABSTRACT
Objective:To apply real-time shear wave elastography to observe the effect of instrument-assisted soft tissue mobilization (IASTM) on Achilles tendons for healthy adults. Methods:From July to December, 2020, 52 healthy adults were assigned into control group (n = 15) and experimental group (n = 37) randomly. The experimental group received IASTM on left Achilles tendons, once another day for two weeks, while the control group received no treatment. The thickness and elastic modulus of the left Achilles tendons were measured with high-frequency ultrasound and shear wave ultrasound elastography on all the subjects, before treatment, immediately after the first treatment and three days after treatment, respectively. Results:Five cases dropped down in the experimental group. There was no significant difference in thickness and elastic Young's modulus of the left Achilles tendons between two groups before treatment (t < 0.630, P > 0.05). The thickness of the left Achilles tendons was less in the experimental group than in the control group immediately after the first treatment (t = 2.149, P < 0.05), while average and maximum elastic Young's modulus was less three days after treatment (t > 2.134, P < 0.05). Conclusion:Real-time shear wave elastography could quantify the thickness and elasticity of Achilles tendon, to evaluate the effect of IASTM.
ABSTRACT
BACKGROUND: Chronic soft tissue injury is easy to occur during daily living, sports training, treatment and rehabilitation of various acute and chronic diseases. Chronic soft tissue injury can cause pain. If there is no good treatment for the injured soft tissue, it is easy to develop limb dysfunctions (such as limited joint movements) due to have cicatricial contraction and adhesion, limited human activity and participation ability, affecting the quality of daily life activities. It can also reduce the effect of sports training or rehabilitation treatment for athletes and patients with various acute and chronic diseases. In recent years, the treatment of chronic soft tissue injury by instrument-assisted soft tissue mobilization has been widely concerned, which has a positive effect on pain relief after chronic soft tissue injury. This technology has been widely studied abroad, but less in China. OBJECTIVE: To summarize the progress of instrument-assisted soft tissue mobilization in the treatment of chronic soft tissue injury. METHODS: PubMed, WanFang, and CNKI were searched. Relevant literature concerning instrument-assisted soft tissue mobilization, chronic soft tissue injury and pain was retrieved and summarized. RESULTS AND CONCLUSION: Instrument-assisted soft tissue mobilization has a positive effect on the improvement of pain and joint limitation caused by chronic soft tissue injury. It has been proved that instrument-assisted soft tissue mobilization can also improve the soft tissue function of healthy people. Instrument-assisted soft tissue mobilization is suggested to be used in clinical treatment and sports training as a means of treatment and prevention. Current basic research on this technology is still insufficient. In the future, in addition to a large number of clinical randomized controlled studies, we should deeply explore its action mechanism to provide theoretical support for clinical application.
