|概要||Background: Conservative management is often the first-choice treatment for baseball |
players with disabled throwing shoulder (DTS). Considering the high popularity of
baseball in Japan, we suspected that there might be some evidence regarding this
topic in the Japanese-language literature.
Objective: This study aimed to systematically review Japanese-language primary
studies investigating the effectiveness of conservative management for DTS in
Methods: Eight databases were systematically searched from inception to 7 April 2016.
Data on authors, publication years, sample characteristics, types of interventions,
outcome measures and results were extracted. Data was synthesised qualitatively.
Results: Seven studies with low evidence level and low to moderate study quality were
included. Interventions examined in the included studies were downward throwing,
combined physiotherapy interventions and joint distension. Form correction, stretching
for posterior shoulder muscles and strengthening exercises to improve scapular/trunk
stability were commonly used in combined physiotherapy interventions. Downward
throwing and combined physiotherapy interventions corresponded with expert opinions
described in the English-language literature. Due to the lack of studies with high level
of evidence, however, it was difficult to determine the genuine effects of these
Conclusions: Our systematic review found limited evidence about the effectiveness of
any conservative management for baseball players with DTS. Although downward
throwing and combined physiotherapy interventions might be appropriate management
in some cases, further studies of higher level of evidence and greater methodological
rigour are required.
