Grip strength was also assessed at the same time intervals and noted an improvement for the corticosteroid group at 4 weeks compared with autologous blood and ESWT. There was no difference noted in grip strength at 12 weeks between the three groups. ESWT performed better at the 26-week follow-up with respect to grip strength when compared with autologous blood and corticosteroid injections. At 52 weeks, there was no significant difference between the three groups with respect to grip strength. At 52 weeks, the success rate for corticosteroid injections was 50%, compared with 83% for autologous blood injections and 89% for ESWT treatments.

This study supported the idea the corticosteroid injections can be helpful for temporary and short term improvement in chronic lateral epicondylitis patients, but that autologous blood and ESWT tend to have more lasting improvements. [28]
