NCT04726189

Brief Summary

The purpose of this trial is to investigate the efficacy of standard care versus standard care combined with an early progressive exercise program in improving the function of the tendon and leg muscles after non-surgical treated Achilles tendon rupture

Outcome Measures

Primary Outcomes (1)

  • Achilles tendon total rupture score ATRS

    Validated patient reported outcome measure. It contains 10 questions about physical performance in an 11-point Likert scale from zero to ten.

    13 weeks

Secondary Outcomes (9)

  • Achilles tendon total rupture score ATRS

    Baseline, 26 and 52 weeks

  • International Physical Activity Questionnaire (IPAQ)

    baseline, 13, 26 and 52 weeks

  • Achilles tendon resting angle (ATRA)

    13 and 52 weeks

  • Achilles tendon length

    9, 13 and 52 weeks

  • Isometric muscle strength

    9, 13 and 52 weeks

  • +4 more secondary outcomes

Other Outcomes (2)

  • Cost-effectiveness outcomes

    9, 13, 26 and 52 weeks

  • Self-reported health state

    Baseline, 9, 13, 26, 52 weeks

Study Arms (2)

Standard care exercises

ACTIVE COMPARATOR

This is the currently used treatment in the nine weeks of immobilisation with an orthosis.

Other: Standard exercises

Early progressive strength exercise

EXPERIMENTAL

This exercise program initiates early (second week) and continues with resistance exercises with progression of the load according to individual participant toleration.

Other: Standard exercises plus Early progressive exercises

Interventions

Consists of a a standard exercise program with range of motion exercises from the third week and elastic band exercise from the sixth week.

Standard care exercises

This exercise program consists of standard exercises plus the early progressive program that initiates early (second week) and continues with resistance exercises with progression of the load according to individual participant toleration. Exercises are isometric exercises from the second week and then gradually progression of load in seated heel-rise and resistance band exercises.

Early progressive strength exercise

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Acute total Achilles tendon rupture treated non-surgically

  • Diabetes or rheumatic diseases
  • Severe medical illness: ASA score higher than or equal to 3. (ASA: American Society of Anesthesiologists physical status classification system)
