Achilles Tendinopathy is common in many athletes following injury, and can lead to tendon degeneration, pain, loss of performance and eventual tendon rupture. A study published in the American Journal of Sports Medicine investigated whether the addition of low level laser therapy (LLLT) for 8 weeks in addition to an eccentric exercise (EE) program would speed recovery and improve outcomes in recreational athletes with chronic Achilles Tendinopathy.
52 athletes with symptoms of at least 6 months of unilateral, activity limiting pain in the Achilles tendon were included. They were randomized into two groups, the first group having EE and LLLT and the second group having EE with placebo LLLT. LLLT and placebo LLLT were administered twice a week for 4 weeks, than weekly for 4 weeks. EE were performed 4 times a week, consisting of unilateral calf raises performed on a step which started with body weight only, and progressed with weight in a back pack, beginning with 1 set of 15 reps and progressing to 12 sets of 12 reps. Static stretching of the Achilles tendon was included.
Outcomes were measured at 4, 8 and 12 weeks. Pain intensity during physical activity was significantly better in the true LLLT group at every stage of assessment, and all secondary outcomes were also significantly better. This study provides evidence that adding LLLT to an EE program may speed recovery and improve outcomes, up to 4 weeks following treatment.
