180 patients with unilateral lateral epicondylitis were randomized to receive either a lateral epicondylitis band (LEB; n=53), a wrist extensor splint (WES; n=53), or joint-protection education only (n=53). The primary outcome of interest was the Patient-Rated Tennis Elbow Evaluation (PRTEE) score. Secondary outcomes included the Visual Analog Scale (VAS) for pain, hand grip strength (HGS), algometric measurements, patient satisfaction, and selected ultrasonographic parameters. Outcomes were assessed at baseline, 3 weeks, and 6 weeks post-intervention. Overall, the results of the study revealed that both LEB and WES were effective in reducing pain and improving functionality. However, LEB was superior to WES in improving hand grip strength and patient satisfaction. This suggests that both splints are viable treatment options, but LEB may offer greater benefits in specific areas.
