Reliability of the Passive Properties of the Calf Muscles in Healthy Subjects Assessed Using Isokinetic Device

NCT04191759 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 16

No results posted yet for this study

Summary

The investigators designed this study to determine the test-retest reliability of the viscoelastic passive properties of the calf muscles assessed using isokinetic device in flexed and extended knee position. The second objective is to determine the clinical viability of the parameters using the coefficient of repeatability and to investigate the individual characteristics associated with increased calf stiffness or altered viscoelasticity

Conditions

  • Tendon Injuries
  • Muscle Tightness

Test-Retest reproducibility

Protocol is the same for extended or flexed knee. The testing apparatus was set up as described in the constructor owner's manual and subjects were positioned in the supine lying position. The After a 5 min rest period, the participant's ankle is passively stretched through slow loading cycles from 15° of ankle flexion to 35° of ankle extension. Oral instruction is given to the participants to stay relaxed and avoid any muscle contraction and movement of the leg throughout the passive stretching. To familiarize, participant have 3 repetitions of passive ankle flexion-extension at 5°.s-1, and after 2min rest, data are collected from one repetitions at 5°.s-1 in passive mode. The measurements are also performed at an angular rate of 90°.s-1, according to the same protocol. Data for maximal voluntary isokinetic contraction are collected from 3 maximal repetitions at 60°.s-1 in concentric mode and participant are encouraged by constant verbal stimulation.
