Clinical Trial Summary

The purpose of this study is to investigate the clinical and functional outcome of a 12-week rehabilitation regime consisting of Low-Load Blood Flow Restriction compared to Heavy-Slow Resistance training in male patients with chronic unilateral patellar tendinopathy.

Clinical Trial Description

Chronic tendinopathy represents a considerable problem in both elite and recreational athletes, and symptoms may affect athletic performance and reduce or even result in retirement from sports participation. The current best treatment is considered to be heavy-slow resistance training (HSRT); however, not all patients are able to cope with heavy exercise loads. Therefore, low-load strength training performed under partial blood flow restriction may be a clinically relevant rehabilitation tool. This project aims to investigate a new innovative intervention to treat chronic unilateral patellar tendinopathy in male individuals using strength training with low-load muscle contractions performed under partial blood flow restriction (LL-BFR), and to compare the resulting treatment outcome to that of the current best practice (HSRT). Specifically, the effect of LL-BFR will be investigated using a randomized controlled trial design with two groups; 1) a low-load blood flow restriction training program, and 2) a heavy-load slow strength training program. A total sample size of 36 participants are needed when assuming a 10 % dropout. The training protocol consist of three weekly training sessions during a 12-week rehabilitation period. The primary outcome is measured using the Single-Leg Decline Squat at 12-week. If LL-BFR proves to be an effective treatment strategy for tendinopathy, it can easily be implemented in daily clinical practice. ;
