“…Twenty-two studies used passive stretching, satisfying the definition of a movement applied by an external force [ 20 – 41 ]. All passive stretching studies anesthetized the animals to manual stretching or stretching achieved with a mechanical device [ 20 – 41 ]. Of the 22 studies, fourteen explored the effect of dynamic muscle activation with a protocol of lengthening and shortening contractions/cycles.…”

A systematic review of in vivo stretching regimens on inflammation and its relevance to translational yoga research

Objective To conduct a systematic review evaluating the impact of stretching on inflammation and its resolution using in vivo rodent models. Findings are evaluated for their potential to inform the design of clinical yoga studies to assess the impact of yogic stretching on inflammation and health. Methods Studies were identified using four databases. Eligible publications included English original peer-reviewed articles between 1900–May 2020. Studies included those investigating the effect of different stretching techniques administered to a whole rodent model and evaluating at least one inflammatory outcome. Studies stretching the musculoskeletal and integumentary systems were considered. Two reviewers removed duplicates, screened abstracts, conducted full-text reviews, and assessed methodological quality. Results Of 766 studies identified, 25 were included for synthesis. Seven (28%) studies had a high risk of bias in 3 out of 10 criteria. Experimental stretching protocols resulted in a continuum of inflammatory responses with therapeutic and injurious effects, which varied with a combination of three stretching parameters––duration, frequency, and intensity. Relative to injurious stretching, therapeutic stretching featured longer-term stretching protocols. Evidence of pro- and mixed-inflammatory effects of stretching was found in 16 muscle studies. Evidence of pro-, anti-, and mixed-inflammatory effects was found in nine longer-term stretching studies of the integumentary system. Conclusion Despite the overall high quality of these summarized studies, evaluation of stretching protocols paralleling yogic stretching is limited. Both injurious and therapeutic stretching induce aspects of inflammatory responses that varied among the different stretching protocols. Inflammatory markers, such as cytokines, are potential outcomes to consider in clinical yoga studies. Future translational research evaluating therapeutic benefits should consider in vitro studies, active vs. passive stretching, shorter-term vs. longer-term interventions, systemic vs. local effects of stretching, animal models resembling human anatomy, control and estimation of non-specific stresses, development of in vivo self-stretching paradigms targeting myofascial tissues, and in vivo models accounting for gross musculoskeletal posture.

“…Finally, they concluded that the laser reduced skeletal muscle edema as well as cytokines, and CRP then led to a significant reduction in inflammatory markers. 11 Through a study guided by Carvalho et al, 15 male rats were distributed into three groups: control group (C), induced myositis without treatment (MI), and treated induced myositis (MT), for seven days. The induction of acute myositis was done with 1% acetic acid by the intramuscular route.…”

Focal myositis (FM) is a rare inflammatory myopathy characterized by a painful swelling of a skeletal muscle. The lower limb is the most common site for FM, but it has also been reported in the abdomen, forearm, neck, and tongue musculature. Some conservative treatments such as non-steroidal anti-inflammatory drugs, physiotherapy, and steroids can relieve muscle pain and its minor complications. This report describes a patient who had shoulder pain and was diagnosed with FM in the left trapezius muscle with an excellent response to high-intensity laser therapy.

“…After the first 24 h postlesion, there is little evidence about the usefulness of pulsed ultrasound therapy (UST) (1 W/cm 2 ) [ 13 ] (often used as cryo-ultrasound, with the adjunct of ice therapy) and low-level laser therapy (LT) (500 mW/cm 2 ) [ 9 , 35 , 36 , 37 ].…”

Muscle injuries are the most common trauma in team and individual sports. The muscles most frequently affected are those of the lower limb, and in particular hamstrings, adductors, rectus femoris and calf muscles. Although several scientific studies have tried to propose different rehabilitation protocols, still too often the real rehabilitation process is not based on scientific knowledge, especially in non-elite athletes. Moreover, the growing use of physical and instrumental therapies has made it increasingly difficult to understand what can be truly effective. Therefore, the aim of the present paper is to review proposed therapeutic algorithms for muscle injuries, proposing a concise and practical summary. Following a three-phase rehabilitation protocol, this review aims to describe the conservative treatment of indirect structural muscle injuries, which are the more routinely found and more challenging type. For each phase, until return to training and return to sport are completed, the functional goal, the most appropriate practitioner, and the best possible treatment according to current evidence are expressed. Finally, the last section is focused on the specific exercise rehabilitation for the four main muscle groups with a structured explanatory timetable.
