Resistance Training and Injection Treatment for Chronic Achilles Tendinopathy
Is Supervised or Homebased Resistance Training the Best Treatment for Chronic Achilles Tendinopathy? And When Needed is Supplement Treatment With Either Corticosteroid or High Volume Injection the Best Choice
Achilles tendinopathy is a common and often long-lasting injury among exercising individuals.
The primary purpose of the study is to compare treatment with supervised or homebased resistance training. The secondary purpose is to compare treatment with either corticosteroid or High Volume Injection (HVI) for those patients not responding to the primary treatment.
The tertiary purpose is to evaluate the effect of surgery in those patients not responding to the primary and the secondary treatment.
It is hypothesized that:
- Homebased resistance training is as effective as supervised resistance training for treating chronic achilles tendinopathy
- HVI injection is better than CS injection for those patients not responding sufficiently to treatment 1
- Surgery improves symptoms in patients not responding to treatment 1 and treatment 2
Study 1: 90 patients between 18 and 65 years of age with achilles tendinopathy for at least 3 months are randomly assigned to either A. Resistance training at home instructed via a smart phone training app and avoidance of pain aggravating activities for 3 months B. Heavy slow resistance training in the gym instructed by a physiotherapist and avoidance of pain aggravating activities for 3 months
Outcomes are change in patient reported outcome (VISA-A) from baseline to 3 and 6 months, ultrasound measured thickness and dopler activity of the achilles tendon, self reported activity level in percentage of the pre injury activity level.
After the 3-month training intervention, and for the following 9 months, those patients that not are satisfied with the outcome will have the opportunity to participate in the second part of the study.
Study 2: Patients from study 1 which not are satisfied with the outcome are randomly assigned to either
A. Same training intervention continued + High Volume Injection (HVI) B. Same training intervention continued + corticosteroid injection
After the 4-month and for the following 8 months, those patients that not are satisfied with the outcome will have the opportunity to participate in the third part of the study.
Study 3: Patients from study 2 which not are satisfied with the outcome are operated

Detailed Description
Achilles tendinopathy is a common and often long-lasting injury among exercising individuals. Treatment options typically include rest from high load weight bearing activities, resistance training, injections with corticosteroid (CS) or High Volume Injection (HVI) and surgery.
The primary purpose of the study is to compare treatment with supervised or homebased resistance training.
The secondary purpose is to compare treatment with either corticosteroid or High Volume Injection (HVI) for those patients not responding to the primary treatment.
The tertiary purpose is to evaluate the effect of surgery in those patients not responding to the primary and the secondary treatment.
It is hypothesized that:
4. Homebased resistance training is as effective as supervised resistance training for treating chronic achilles tendinopathy (RCT, non-inferiority design).
5. HVI injection is better than CS injection for those patients not responding sufficiently to treatment 1. (RCT, superiority design).
6. Surgery improves symptoms in patients not responding to treatment 1. and treatment 2. (prospective cohort).
Study 1: 90 patients with achilles tendinopathy are randomly assigned to either
C. Resistance training at home instructed via a smart phone training app and avoidance of pain aggravating activities for 3 months D. Heavy slow resistance training in the gym instructed by a physiotherapist and avoidance of pain aggravating activities for 3 months
Inclusion criteria
- Pain from the achilles tendon either unilateral or bilateral for at least 3 months
- Achilles tendinopathy in the tendon midsubstance verified by ultrasound
- Between 18 and 65 years of age
- For patients with unilaterale symptoms the symptomatic tendon must be at least 20% thicker than on the asymptomatic side or more than 7 mm thick
- For patients with bilateral symptoms the achilles tendons must have diameters above 7 mm Exclusion criteria
- Prior surgery in the leg with the exception of knee arthroscopy
- Known medial conditions including diabetes or rheumatologic diseases
- Taking pain medication regularly
- Injection therapy for treatment of achilles tendinopathy within the last 6 months
Patients are stratified based on the severity of symptoms (below or above 50 on VISA-A) and duration of symptoms (shorter or longer than 1 year)

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from baseline in The Victorian Institute of Sports Assessment - Achilles Questionnaire (VISA-A).
Time Frame: After 3 and 6 months in study 1. After 6 months in study 2. After 6 and 12 months in study 3.

VISA-A is a patient reported outcome measure (PROM).
Change from baseline is measured and reported.
The scale ranges from 0-100 points.
Higher score meaning a better outcome.
