Isokinetic muscle assessment after treatment of pectoralis major XXXX using surgical or non-surgical procedures.

@entity130 @entity3986 @entity717 @entity121 @entity922
INTRODUCTION: Rupture of the pectoralis major muscle appears to be increasing in athletes. However, the optimal treatment strategy has not yet been established. OBJECTIVES: To compare the isokinetic shoulder performance after surgical treatment to that after non-surgical treatment for pectoralis major @entity121 . METHODS: We assessed 33 pectoralis major @entity121 (18 treated non-surgically and 15 treated surgically). Horizontal abduction and adduction as well as external and internal rotation at 60 and 120 degrees/s were tested in both upper limbs. Peak torque, total work, @entity717 , and the peak torque agonist-to-antagonist ratio were measured. RESULTS: @entity3986 did not differ between the surgical and non-surgical treatment modalities. However, the surgical group presented twice the number of athletes with clinically acceptable @entity717 (<20%) for internal rotators compared to the non-surgical group. The peak torque ratio between the external and internal rotator muscles revealed a similar @entity717 in both groups and on both sides (surgical, 61.60% and 57.80% and non-surgical, 62.06% and 54.06%, for the dominant and non-dominant sides, respectively). The peak torque ratio revealed that the horizontal adduction muscles on the injured side showed similar weakness in both groups (surgical, 86.27%; non-surgical, 98.61%). CONCLUSIONS: This study included the largest single series of athletes reported to date for this @entity130 . A comparative analysis of muscular strength and balance showed no differences between the treatment modalities for pectoralis major @entity121 . However, the number of significant @entity922 was lower in the surgical group than in the non-surgical group, and both treatment modalities require greater attention to the rehabilitation process, especially for the recovery of muscle strength and balance.
