Handheld vibration massagers can efficiently deliver vibration therapy to the shoulder joint and may be a potential treatment.<\/jats:p>\n <\/jats:sec>\n \n Purpose<\/jats:title>\n To evaluate the effects of vibration massage using a handheld device on the soft tissues of the posterior shoulder joint, particularly on internal rotation (IR) passive ROM and external rotation (ER) muscle strength.<\/jats:p>\n <\/jats:sec>\n \n Study Design<\/jats:title>\n Crossover study design.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n A crossover study with a 5-min vibration massage and passive control condition was conducted in healthy male volunteers (mean age 20.5 \u00b1 1.7 years). Vibration massage was applied to the posterior shoulder soft tissues of the dominant arm, with no intervention under control conditions. IR-ROM (vertebral level and in abduction) and strength of the external rotators (isometric and isokinetic) were measured before and immediately after the intervention. Vertebral levels were calculated as a ratio of lengths (ratio decreases with increased mobility). IR-ROM in abduction, the angle was measured. Statistical analysis was performed with two-way repeated measures ANOVA and paired t-test (Bonferroni correction).<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Vibration application decreased (improved) vertebral level IR ROM by \u22124.1% (p < 0.01, d = 0.445) and increased abduction position IR ROM by 11.4\u00b0 (p < 0.01, d = 0.694). These changes exceeded the 95% confidence interval for the minimum detectable change. By contrast, the control condition produced no changes. IR-ROM (vertebral level and abduction) immediately after the intervention showed significant differences between the control and vibration conditions (p = 0.036, d = 0.273; p = 0.048, d = 0.483, respectively). Muscle strength did not show any interaction, time, or between-condition effects.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n A massage using a handheld vibration massager applied to the posterior shoulder soft tissues increased IR-ROM without negatively affecting muscle strength, suggesting its potential use as a means of warming up.<\/jats:p>\n <\/jats:sec>\n \n Level of Evidence<\/jats:title>\n Level 3<\/jats:p>\n <\/jats:sec>","DOI":"10.26603\/001c.121299","type":"journal-article","created":{"date-parts":[[2024,8,1]],"date-time":"2024-08-01T07:55:25Z","timestamp":1722498925000},"source":"Crossref","is-referenced-by-count":4,"title":["Acute Effects of Handheld Vibration Massage on Posterior Shoulder Soft Tissues"],"prefix":"10.26603","volume":"19","author":[{"given":"Takaki","family":"Imai","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/050r2qc20","id-type":"ROR","asserted-by":"publisher"}],"name":"Kyushu University of Nursing and Social Welfare","department":["Department of Rehabilitation"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takashi","family":"Nagamatsu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/050r2qc20","id-type":"ROR","asserted-by":"publisher"}],"name":"Kyushu University of Nursing and Social Welfare","department":["Department of Rehabilitation"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yushin","family":"Yoshizato","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/050r2qc20","id-type":"ROR","asserted-by":"publisher"}],"name":"Kyushu University of Nursing and Social Welfare","department":["Department of Rehabilitation"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kodai","family":"Miyara","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/050r2qc20","id-type":"ROR","asserted-by":"publisher"}],"name":"Kyushu University of Nursing and Social Welfare","department":["Department of Rehabilitation"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megumi","family":"Sumizono","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/050r2qc20","id-type":"ROR","asserted-by":"publisher"}],"name":"Kyushu University of Nursing and Social Welfare","department":["Department of Rehabilitation"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masatoshi","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Nishi Kyushu University","department":["Faculty of Rehabilitation Sciences"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"11140","published-online":{"date-parts":[[2024,8,2]]},"reference":[{"issue":"1","key":"ref1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1139\/apnm-2015-0235","article-title":"Acute effects of muscle stretching on physical performance, range of motion, and injury incidence in healthy active individuals: a systematic review","volume":"41","author":"D.G.
