Clinical Trial Summary

This work is designed as a prospective cohort study, in which the effects of a protocol of 12-week resistance training loading the Achilles tendon in patients with Achilles tendinopathy (AT) will be monitored. It is estimated that at least 20 patients will participate. In addition, there will be a small control group of healthy participants which will not complete the same protocol, but will be monitored for natural changes in same objectives. Group of patients will be instructed to perform a training protocol.

Description:

The research within one participant will last a total of 26 weeks from the initial to the final examination and will include control measurements at 6 and 12 weeks from the beginning of therapy. Potential participants will be selected based on the recommendation of a specialist doctor and their suitability will be assessed according to the inclusion criteria. They will then be invited to an initial examination. This will include an objective examination by a physiotherapist, a subjective assessment by the patient and an ultrasonographic (USG) examination followed by a micromorphological analysis using special software. At the end of the initial examination, the participant will be informed about training protocol.

Eligibility

Inclusion Criteria:

• the patient shows symptoms of Achilles tendinopathy (pain, swelling and dysfunction in the area of Achilles tendon), which at least partially limit his quality of life during normal or sporting activities,
• the patient is in the age group of 18-60 years,
• the patient has difficulties in only one lower limb; the second, asymptomatic limb will be considered the reference,
• the patient is not aware of any mechanical damage to the tendon in symptomatic limb in the past (e.g. partial or complete rupture as a result of an injury),
• the patient has not undergone any treatment aimed at AS in the last 3 months (surgery, corticoid application, plasma therapy, shock waves, physiotherapy, etc.), objective US examination of AS shows structural changes (expansion, neovascularization, focal hypoechoic areas, etc.).

Exclusion Criteria:

• patient has been diagnosed with a rheumatic disease or a disease of the central nervous system
• patient is aware of mechanical damage to the Achilles tendon as a result of an injury in the past.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Peak Spatial Frequency Radius at the site of Pathology	Measured by spatial frequency analysis software from ultrasound picture in mm-1. In a linear view with specific settings of ultrasound machine, the site of the largest pathology is selected, then the image is saved and uploaded to the software that evaluates the PSFR parameter.	Change of initial values at 26 weeks follow up after beginning of the therapy.
Primary	Change in Tendon Diameter at the Place of Maximum Tendon Width	Measured by tools in ultrasound machine in mm2. In linear view is selected maximal width place, then the tendon diameter is measured using device tools.	Change of initial values at 26 weeks follow up after beginning of the therapy.
Secondary	Change in VISA-A Questionnaire Score	The VISA-A questionnaire is standardized questionnaire for patients with Achilles tendinopathy. The results are recorded in points (0-100 points). The higher score indicates patients better condition.	Change of initial values at 39 weeks follow up after beginning of the therapy.
