In today’s society, a large proport

In today’s society, a large proportion of the population participates in exercise. However, when the general public overexert themselves with high-intensity exercise or long periods of exercise with poor posture, injuries to the soft tissues, such as muscles, ligaments, and tendons, can occur (Hart, 1994; Yeung and Yeung, 2001). Because sports injuries reduce soft tissue function and increase pain, they can have a negative impact on maintaining one’s optimal conditioning. Therefore, rehabilitation after a sports injury is critical, and several interventions have been proposed to help the process of healing. These include electroacupuncture, extracorporeal shockwave therapy, hyperbaric oxygen therapy, laser therapy, prolotherapy, and whole body cryotherapy (Barata et al., 2011; Costello et al., 2015; Delbari et al., 2007; Inoue et al., 2015; Steinacker and Steuer, 2001; Topol et al., 2005). However, some of these methods require expensive equipment and their effectiveness is still being debated.
