Effects of Plantar Region Shiatsu Treatment on the Variance of Center of Gravity

Koichi Hoshino, Munetaka Hibi / Yosuke Ishizuka


Abstract : There are few studies on the effects of plantar region shiatsu treatment on the motor system. In this study, the effects of plantar region shiatsu treatment on balance in the upright position were verified using a stabilograph. Four healthy subjects underwent plantar region shiatsu treatment with each session lasting for 1 min and 42 s. Our results show no significant differences between the shiatsu group and the control group for total trajectory, outer circumference area, rectangle area, or effective value area. Revision of both the subject population and the methods used are needed for further research on this topic.

Measurement of the Psychological Influence of Full Body Shiatsu Therapy: a Case Report

Shinpei Oki


Abstract : With the aim of reducing psychological stress, a female patient in her twenties had three sessions of full body shiatsu therapy between 5/24/2015 and 6/7/2015. The psychological influence of the full body shiatsu therapy was measured using the Profile of Mood States (POMS). After the course of the full body shiatsu therapy, all the T-scores of the six factors improved. This suggests that the full body shiatsu therapy has a stress-relief effect, and further studies are required to verify this.

Shiatsu Therapy for a Patient with Suspected Peripheral Neuropathy while Diagnosed with Traumatic Cervical Spinal Cord Injury

Ichiro Maruyama


Abstract : A patient with traumatic cervical spinal cord injury and suspected peripheral neuropathy (flaccid paralysis of the lower extremities) was treated with shiatsu therapy with the aim of releasing dorsal muscle tension. After a course of 29 sessions of shiatsu therapy, the lower-limb motor function recovered. This suggested the presence of significant muscle hypertonicity alongside the spine was significantly related to the motor dysfunction caused by the peripheral neuropathy. Considering other reports on the improvement of muscle flexibility with shiatsu therapy, we conclude that in our patient, the release of muscle tension by the shiatsu therapy improved blood circulation and the range of motion of the spine, leading to recovery in motor function.

A case of posture correction by a combination of pressure application and exercise therapy

Genta Niikura


Abstract : Many people with subjective symptoms such as stiff shoulder or low back pain are encountered in clinical practice. Here we report a case where shiatsu therapy helped the patient achieve symptom relief and better posture. Shiatsu therapy not only released the muscle tension but also adjusted the joints. Shiatsu therapy involves a combination of pressure application and exercise therapy, and it is possible that this combination had effects on both muscles and joints and helped achieve the favorable outcomes in the present case.

Effects of Inguinal Region Shiatsu Treatment on the Ability to Walk

Hiroki Koizumi / Yasutaka Kaneko


Abstract : The effects of inguinal region shiatsu treatment on the ability to walk were verified using the timed up and go test (TUG). The post-treatment time was shorter than the pre-treatment time. This result suggests that shiatsu treatment may improve the ability to walk at least temporarily.

Effects of Abdominal Region Shiatsu Based on Namikoshi Shiatsu Therapy’s Standard Procedures on Short-Distance Sprint Performance

Keisuke Okubo, Maho Nakano / Hiroyuki Ishizuka


Abstract : Ahead of the 2020 Tokyo Olympic Games, sports is receiving increasing attention in Japan. The aim of this study was to verify the effects of Namikoshi shiatsu therapy’s standard procedures on sport performance. After adequate warm-up, five 50-meter sprints separated by five-min-intervals were timed, and images were taken with a fixed camera to analyze its influences on posture. Twenty points on the abdomen, which were based on Namikoshi shiatsu therapy’s standard procedures, were treated three times before the first sprint and during each interval between the sprints. On a different day, splinters performed five 50-meter sprints separated by five-min-intervals in the supine position without shiatsu treatment. On an average, the shiatsu-treated group had shorter sprint times than the control group. When camera images were compared between the shiatsu-treated and control groups, differences were observed in twisting of the trunk, flexion of the knee joint, and stride length. These results suggest that the 20-point abdominal-region shiatsu based on Namikoshi shiatsu therapy’s standard procedures may have positive effects on the sprint performance.
