Title: Case study for a patient with ACL reconstruction in the Bulgarian squat compared to a healthy patient


In order to study the rehabilitation progress of a patient undergoing anterior cruciate ligament (ACL) reconstruction surgery on the right leg. This subject was compared with a healthy patient who performs physical activity with regularity. They carried out similar physical activities focusing mainly on the “Bulgarian squat” exercise for two months. To evaluate the rehabilitation process, movement captures were made before and after two months of rehabilitation by performing the Bulgarian squat. Movement capture was performed with optoelectronic cameras using the Rizzoli marker protocol. In addition, electromyography data were obtained from five muscles required for this movement (biceps femoris, rectus femoris, gluteus, vastus lateral and medial), where the vastus lateralis was always taken on immobile leg.The kinematic and kinetic analyzing results were made using the Opensim® software. An improvement in stability was observed in the subject with ACL injury after two months of rehabilitation. However, contrary to expectations, his muscle activity decreased on the second dose. In contrast to what happened with the control subject, who maintained the same muscle stability and activity before and after the two months evaluated.

Audience Take Away Notes :

  • The audience will be able to understand how, from simple exercises, patients evolve in terms of ACL injuriesHow will this help the audience in their job? 
  • Provides information on the patient's recovery and can more effectively determine the level of recovery, as well as giving the patient freedom to resume sports activitiesDoes this provide a practical solution to a problem that could simplify or make a designer’s job more efficient? 
  • This study may be useful in cases of knee orthosis for the recovery processList all other benefits.
  • It compares the progress in the subject with exercise, observes its improvement in terms of ligament recovery, can be used to standardize the recovery time of a ligament after this type of injury


I am an undergraduate student of Biomedical Engineering in the 7th semester, at the Military University Nueva Granada of Colombia. I'm very interested in motion analysis thanks to the encouragement of my professor Derian Espinosa who teaches me the human biomechanics class. I am very interested in starting to publish my works to gain more experience in the areas that interest me.
