Tokyo, Oct. 9 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000059344) titled 'Study on the effect of stretching the flexor carpi ulnaris muscle to prevent baseball elbow injuries' on Oct. 9.

Study Type: Interventional

Study Design: Basic Design - Parallel Randomization - Randomized Blinding - Open -no one is blinded Control - Dose comparison

Primary Sponsor: Institute - Akita University

Condition: Condition - baseball elbow injuries Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - Increased elbow valgus load during pitching is thought to be involved in the development of baseball elbow. The forearm flexor and pronator muscles function as dynamic stabilizers against valgus stress during pitching. The flexor carpi ulnaris, in particular, is a key muscle covering the medial collateral ligament and is believed to contribute significantly to suppressing valgus during pitching. Muscles exhibit increased elasticity with repeated contraction or contraction under heavy loads. Players with medial baseball elbow injury during development have been shown to have higher flexor carpi ulnaris elasticity compared with healthy players. Furthermore, prospective studies have reported that high flexor carpi ulnaris elasticity is a risk factor for baseball elbow. Therefore, improving flexibility of the flexor carpi ulnaris may prevent baseball elbow, and stretching for this muscle is considered important. However, while there are various stretching methods for the flexor carpi ulnaris, their effectiveness has not been fully investigated, and effective stretching techniques for this muscle have not been identified. Therefore, the purpose of this study is to use ultrasound elastography to measure muscle elasticity before and after various stretching exercises for the flexor carpi ulnaris, clarify the effects, and use this as an aid in physical therapy for baseball elbow injuries. Basic objectives2 - Efficacy

Intervention: Interventions/Control_1 - With the shoulder flexed at 90 degrees, the forearm supinated at 90 degrees, and the wrist dorsiflexed at 90 degrees, stretching was performed for 20 seconds in two sets, extending the four fingers except for the thumb. Interventions/Control_2 - With the shoulder flexed at 90 degrees, the forearm pronated at 90 degrees, and the wrist dorsiflexed at 90 degrees, stretching was performed for 20 seconds in two sets, extending the four fingers except for the thumb.
