In a previous uncontrolled pilot study we demonstrated very good clinical results with eccentric calf muscle training on patients with painful chronic Achilles tendinosis located at the 2–6 cm level in the tendon. In the present prospective multicenter study (Sundsvall and Umeå) patients with painful chronic Achilles tendinosis at the 2–6 cm level in the tendon were randomized to treatment with either an eccentric or a concentric training regimen for the calf muscles. The study included 44… Expand

A STUDY TO COMPARE THE EFFICACY OF ULTRASOUND WITH ECCENTRIC EXERCISES AND ULTRASOUND WITH CONCENTRIC EXERCISES ON TENDO ACHILLES TENDINITIS IN ATHELETES
TLDR
Patients with painful chronic Achilles tendinosis at the 2-6 cm level in the tendon were randomized to treatment with either an eccentric or a concentric training regimen for the calf muscles with therapeutic ultrasound as the common modality. Expand
Eccentric calf muscle training compared with therapeutic ultrasound for chronic Achilles tendon pain--a pilot study.
TLDR
Both interventions proved acceptable to the patients with no adverse effects and the potential effectiveness compared with therapeutic ultrasound in subjects with relatively sedentary lifestyles in an NHS hospital setting is investigated. Expand
New regimen for eccentric calf-muscle training in patients with chronic insertional Achilles tendinopathy: results of a pilot study
TLDR
A new model of painful eccentric calf-muscle training showed promising clinical results in 67% of the patients, and this was done as 3×15 reps, twice a day, 7 days/week, for 12 weeks. Expand
Clinical improvement after 6 weeks of eccentric exercise in patients with mid‐portion Achilles tendinopathy – a randomized trial with 1‐year follow‐up
TLDR
It is concluded that eccentric exercises seem to reduce pain and improve function in patients with Achilles tendinopathy, and the recommendation that patients should undergo an eccentric exercise program prior to considering other treatments such as surgery is strengthened. Expand
Eccentric training in patients with chronic Achilles tendinosis: normalised tendon structure and decreased thickness at follow up
TLDR
Ulasonographic follow up of patients with mid-portion painful chronic Achilles tendinosis treated with eccentric calf muscle training showed a localised decrease in tendon thickness and a normalised tendon structure in most patients. Expand
One-year follow-up of a randomised controlled trial on added splinting to eccentric exercises in chronic midportion Achilles tendinopathy
TLDR
Eccentric exercises with or without a night splint to eccentric exercises improved functional outcome at one year follow-up, and assessment of the neovascularisation score with PDU at baseline has no prognostic value on long-term clinical outcome. Expand
Chronic Achilles tendon pain treated with eccentric calf-muscle training
TLDR
The conclusion is that treatment with eccentric calf-muscle training produced good clinical results in patients with chronic painful mid-portion Achilles tendinosis, but not in Patients with chronic insertional Achilles tendon pain. Expand
The long-term clinical and MRI results following eccentric calf muscle training in chronic Achilles tendinosis
PurposeTo evaluate the long-term results following eccentric calf-muscle training in patients with chronic Achilles tendinopathy.Materials and methodsA total of 24 patients with chronic AchillesExpand
Comparing the effects of eccentric training with eccentric training and static stretching exercises in the treatment of patellar tendinopathy. A controlled clinical trial
TLDR
Eccentric training and static stretching exercises is superior to eccentric training alone to reduce pain and improve function in patients with patellar tendinopathy at the end of the treatment and at follow-up. Expand

Heavy-Load Eccentric Calf Muscle Training For the Treatment of Chronic Achilles Tendinosis
TLDR
The treatment model with heavy-load eccentric calf muscle training has a very good short-term effect on athletes in their early forties. Expand
Achilles Tendinosis and Calf Muscle Strength
TLDR
It seems that the recovery in concentric and eccentric calf muscle strength after surgery for Achilles tendinosis is slow, with no obvious advantages in recovery of muscle strength with a short immobilization time versus a longer period used in a previous study. Expand
Achilles tendon overuse injuries.
TLDR
Treatment of the patient with paratenonitis and tendinosis is initially conservative, emphasizing passive stretching, concentric and eccentric strengthening, correction of training errors, and restoration of normal limb alignment. Expand
Achilles tendinitis and peritendinitis: Etiology and treatment
TLDR
The authors speculate that runners are susceptible to Achilles tendinitis with peritendinitis due to micro- trauma produced by the eccentric loading of fatigued muscle, excess pronation producing whipping action of the Achilles tendon, and/or vascular blanching. Expand
On the nature and etiology of chronic achilles tendinopathy
TLDR
Most patients were athletes but physical activity was not correlated to histopathology and could be more important in provoking symptoms than in the evolution of the actual lesion, refuted the popular theory of the mid-tendon hypovascular zone as a cause of ruptures and chronic lesions. Expand
No effect of piroxicam on achilles tendinopathy. A randomized study of 70 patients.
TLDR
The overall result was identical with a rate of success slightly better than 50 percent which corresponds to the placebo response reported in other studies. Expand
Achilles tendon injuries in athletes.
TLDR
The typical histological features of chronically inflamed paratendineal tissue of the Achilles tendon are profound proliferation of loose, immature connective tissue and marked obliterative and degenerative alterations in the blood vessels which may have an important role in the pathophysiology of these injuries.

TLDR
Jumper's knee is characterized by consistent changes at MR imaging, US, and histopathologic examination and is appropriately described as patellar tendinosis. Expand
Exercise Loading of Tendons and the Development of Overuse Injuries
TLDR
Since blood flow is commonly implicated in the emergence of tendinitis, the final section covers recent work on blood flow and tendon physiology and suggests for further research into exercise loading and the development of tendon overuse injuries. Expand
Diagnosis and treatment of chronic tendon disorders in sports
TLDR
As high level athletes continue to reach higher levels of performance more amateur athletes attempt to reach similar levels of intensity, which they may not be able to handle with their level or method of training, this has led to an increase in overuse injuries and chronic tendon injuries. Expand
