Effects of Low-Level Laser Therapy and Eccentric Exercises in the Treatment of Recreational Athletes with Chronic Achilles Tendinopathy

Abstract

Low-level laser therapy, with the parameters used in this study, accelerates clinical recovery from chronic Achilles tendinopathy when added to an EE regimen. For the LLLT group, the results at 4 weeks were similar to the placebo LLLT group results after 12 weeks.

Achilles Pain, Stiffness, and Muscle Power Deficits: Achilles Tendinitis

“…Improvements in the intervention group were also noted in secondary measures, including tenderness to palpation, crepitation, morning stiffness, and active dorsiflexion range of motion. 127 An additional study in 7 patients with bilateral Achilles tendinopathy yielded positive results when examining the influence of LLLT. 12 Using a 904-nm probe, at 5.4 J per point, Bjordal and colleagues, 12 identified that LLLT can reduce pain and inflammation associated with an acute (exercise induced) exacerbation of Achilles tendonitis.…”

“…130 Few studies, however, have overtly examined the influence of LLLT in human subjects with Achilles tendinopathy. 12,127 LLLT enhanced outcomes in a group of 20 subjects (12 male, 8 female), when coupled with eccentric exercises, compared to 20 subjects (13 male, 7 female) in an eccentric exercise group who received placebo laser treatment. 127 There were no statistical differences in age, height, weight, symptom duration, or quantity of active ankle dorsiflexion between the randomly assigned groups.…”

The Effects of Low-Level Laser Therapy on Pain Associated With Tendinopathy: A Critically Appraised Topic

“…Five relevant studies [3][4][5][6][7] were located and categorized as shown in Table 1 (based on Levels of Evidence, Centre for Evidence Based Medicine, 2011).…”

“…Tendinopathies are clinically relevant to athletic trainers and sports-medicine rehabilitation experts. The potential benefits of managing pain associated with tendinopathy have been investigated using low-level laser therapy (LLLT) [3][4][5][6][7] and are still somewhat inconclusive. Further exploration, however, into the clinical effectiveness of using LLLT is warranted.…”
