Official title: Effects of Kontralateral Training in Patients With Bankart Lesion
Study type: INTERVENTIONAL
Overall status: COMPLETED
Phase: NA
Conditions: Strenght of Rotator Cuff Muscles
Keywords: Kontralateral Education, Bankart, Rehabilitation, Shoulder,
Lead sponsor: Hacettepe University
Sponsor class: OTHER

Enrollment: 30
Sex: ALL
Minimum age (years): 18
Maximum age (years): 45
Standard ages: ADULT
Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Randomized Control, Parallel Group Study
Primary purpose: TREATMENT

Brief summary: The rate of re-dislocation after arthroscopic bankart repair is up to 30%. The most important dynamic structure that prevents re-dislocation is the rotator cuff muscles. The aim of our study is to investigate the efficacy of contralateral training on patients with arthroscopic Bankart surgery. Patients with arthroscopic Bankart surgery will be included in the study. The patients will be randomly assigned into 3 groups and the first group will be the control group, the second group will be the concentric group and the third group will be the eccentric group. Standard rehabilitation program will be applied to all groups until 3 months after surgery. Between 2nd and 12nd weeks after surgery, concentric strengthening program will be applied to the rotator cuff muscles with isokinetic dynamometer to the 2nd group. In group 3, the eccentric strengthening program will be applied to the rotator sheath muscles with the same isokinetic dynamometer from the 2nd week until 12nd week .

The strength of the rotator sheath muscles will be measured in pre-op period, post-op week 12 and post-op month 6 with the isokinetic dynamometer in all patients. In addition, functional tests will be performed in pre-op period and post-op 6 months (Y balance test for upper extremity, Closed Kinetic Chain Upper Extremity Stability Test and Medicine Ball Throw Test).
