NCT05254054 | Unknown DMC

• 1 other identifier: 2019.432
• Study Type: interventional
• Target: 50
• Locations: 1 country
• Sites: 1

Brief Summary

This is a randomised clinical trial to detect the effect of an 8-week whole body vibration training on muscle function and dynamic knee function during single leg squat and single leg hop in patients after anterior cruciate ligament reconstruction

Conditions

ACL Injury

Keywords

ACL; dynamic knee stability; whole body vibration

Outcome Measures

Primary Outcomes (6)

• knee flexion angle

  Peak value of knee flexion will be assessed by the skin marker-based motion analysis system (Vicon MX, Oxford, UK) during single leg squat and single leg hop landing.

  immediately after intervention, three month after intervention

• knee valgus angle

  Peak value of knee valgus will be assessed by the skin marker-based motion analysis system (Vicon MX, Oxford, UK) during single leg squat and single leg hop landing.

  immediately after intervention, three month after intervention

• knee internal rotation angle

  Peak value of knee internal rotation will be assessed by the skin marker-based motion analysis system (Vicon MX, Oxford, UK) during single leg squat and single leg hop landing.

  immediately after intervention, three month after intervention

• Vertical ground reaction force

  Peak vertical ground reaction force will be evaluated by a synchronized force plate during single leg hop landing.

  immediately after intervention, three month after intervention

• Knee valgus torque

  Peak knee valgus torque will be evaluated by a synchronized force plate during single leg hop landing.

  immediately after intervention, three month after intervention

• Knee extension torque

  Peak knee extension torque will be evaluated by a synchronized force plate during single leg hop landing.

  immediately after intervention, three month after intervention

Secondary Outcomes (3)

• muscle strength

  immediately after intervention, three month after intervention

• muscle elasticity

  immediately after intervention, three month after intervention

• muscle activation

  immediately after intervention, three month after intervention

Study Arms (2)

Vibration group

EXPERIMENTAL

Participants in Vibration group will receive an 8-week whole body vibration training in addition to conventional exercise training.

Other: whole body vibration; Other: Conventional exercise training

Control group

ACTIVE COMPARATOR

Participants in Vibration group will only receive conventional exercise training.

Other: Conventional exercise training

Interventions

whole body vibration OTHER

The whole body vibration is used when vibrations (mechanical oscillations) of a certain frequency are transferred to the human body. Humans are exposed to vibration through a contact surface that is in a mechanical vibrating state. It has been considered as an alternative and safe method for neuromuscular training and may be incorporated into current neuromuscular rehabilitation programs so as to enhance muscle recovery

Vibration group

Conventional exercise training OTHER

A set of conventional exercises designed for ACL rehabilitation

Control group; Vibration group
