Upper limb kinematics after arthroscopic and open shoulder stabilization

Pain intensity attenuates movement control of the lumbar spine in low back pain

“…Participants in the present study were asked to perform the repetitive movement with a predetermined, fast speed, possibly overriding any protective feedforward strategy of movement control. This contrasts findings from two studies (Arzi et al,2014, Uri et al,2015 who showed that patients after shoulder surgery had less variable kinematics of the shoulder joint when moving at self-selected slow and fast speed. To test this hypothesis the repetitive "Pick up a box" task should be performed at self-selected preferred, slow, and fast speed.…”

Rotator cuff tendinopathy alters the muscle activity onset and kinematics of scapula

“…In healthy shoulders, it is expected to see more variance in the activity onset of the scapular muscles for more adaptability during shoulder movement. In this way, patients with RC tendinopathy may implement a rather stereotype activation pattern of the scapular muscles during shoulder elevation, which has been suggested in other studies that showed patients with recurrent anterior shoulder instability may implement a preplanned stereotypical movement for the arm kinematics when compared to the healthy controls (Arzi et al, 2014, Uri et al, 2015. The idea of this activation adaptability in those with RC tendinopathy warrants further investigations.…”

“…When comparing the change in scapular rotation at different phases of shoulder abduction, athletes with RC tendinopathy demonstrated less scapular upward rotation during early shoulder abduction from 0° to 30° than their asymptomatic counterparts (by 2°). These small changes in the scapular upward rotation between the two groups may be attributed to the differences in the sensorimotor processing or proprioceptive changes (Uri et al, 2015), and may signify some deficits in the dynamic control of the scapula in athletes with RC tendinopathy during early shoulder abduction. Our finding was similar to the study reported by Su et al (2004) in which swimmers with RC tendinopathy were found to have a decrease in upward scapular rotation during early shoulder elevation at 45° after a session of intense swimming practice.…”

Arthroscopic Bankart repair improves upper limb exercise capacity, shoulder function and quality of life

“…It was needed to include as many patients as possible from both genders. But there are some studies that have been done with a similar sample size [ 6 , 28 , 31 , 32 ]. We considered AROM and muscle strength were not deterministic values for this patient group, further studies are needed to reveal the potential relationship between exercise capacity and these parameters in patients with glenohumeral instability.…”

“…Performance-based evaluations may be essential in order to plan both physiotherapy programs [ 3 ]. Several researchers have investigated the upper-limb kinematics [ 6 ], muscle strength [ 3 , 5 , 7 ], range of motion (ROM) [ 3 , 4 , 7 ], and function of the shoulder [ 8 ] before and after the operation. However, to the best of our knowledge, no data are available concerning changes in arm exercise capacity in this specific patient group.…”
