“…The full texts of the seven remaining papers were retrieved and assessed in more detail for eligibility, and one study was excluded as the intervention protocol for the comparison group was inconsistent with the inclusion criteria. Finally, six studies [36][37][38][39][40][41] with a total of 429 participants, were included in the meta-analysis.…”

“…Two studies [36,37] were determined to have a high risk of random sequence generation because they used methods of convenient sampling or allocation according to the judgment of the clinician. Two studies [38,41] provided insufficient details regarding how randomization was performed and were determined to have an unclear risk of bias.…”

“…Two studies [38,41] provided insufficient details regarding how randomization was performed and were determined to have an unclear risk of bias. In all six studies [36][37][38][39][40][41], the methods did not describe the allocation concealment, and all studies were determined to have an unclear risk. As these studies were experimental trials of performing eccentric exercises by the participants themselves, complete participant blinding seemed difficult.…”

“…One study [39] with an unblinded assessor was considered to have a high risk of assessment blinding. A high risk of selective reporting was ascribed to two studies [36,37] that did not report the scales of pre-intervention. We only included studies from which the effects of eccentric exercise could be evaluated: (eccentric exercise + adjuvant therapy vs. same adjuvant therapy) or (eccentric exercise vs. other strengthening exercises).…”

“…The average age of the participants ranged from 38 [37] to 51 [41] years. Four of the studies [37,[39][40][41] clearly identified participants of both sexes; however, the remaining studies failed to report participant sex [36,38]. Four studies [36][37][38]40] compared the effects of eccentric exercise and adjuvant therapy versus the same adjuvant therapy, and three studies [38,39,41] evaluated the effects of eccentric exercise in comparison to other exercises such as concentric or isotonic exercise.…”

As a first-line treatment for lateral elbow tendinopathy (LET), eccentric exercise has been suggested as a conservative treatment method. This study aimed to investigate the impact of eccentric exercise on LET with regard to pain reduction, and strength and functional improvement. The PubMed, EMBASE, and Cochrane Central Register of Controlled Trials databases were searched, and studies up to May 2021 were included if (1) randomization was used for patient allocation, (2) the study comprised patients with LET, (3) the intervention was eccentric exercise, and (4) the primary outcomes included improvement in pain intensity, muscle strength, or function. The meta-analysis comprised of six studies, totaling 429 participants. Additional eccentric exercise with underlying adjuvant therapy significantly improved the visual analog scale (VAS) scores (standardized mean difference [SMD], −0.63; 95% confidence interval [CI], −0.90–−0.36) and muscle strength (SMD, 1.05; 95% CI, 0.78–1.33) compared with adjuvant therapy alone. Compared with the concentric or isotonic exercise group, the eccentric exercise group showed significantly improved VAS scores (SMD, −0.30; 95% CI, −0.58–−0.02). However, no differences in muscle strength and function were observed between the two groups. Eccentric exercise can improve pain and muscle strength in patients with LET. The limited number of included studies and heterogeneous exercise parameters are important when interpreting these findings.
