“…The tests applied for the balance evaluation may use various destabilizing (957) factors, like support surface modification (one foot standing), dynamic tests (jumping in place or using electronic platforms with infinite degrees of freedom). Stability control is also impaired by disruption of the sensory system involved in the balance support especially when visual stimuli are limited [11,12,[17][18][19].…”

Ligament reconstruction is one of the surgical methods for treatment of anterior cruciate ligament injury. The main purpose of rehabilitation after surgical ligament reconstruction is to obtain maximal efficiency of knee joint, their stability and appropriate lower limbs encumbrance. Static posturography is one of the control, rehabilitative and diagnostic tools in such treatment. The purpose of the study was to evaluate the posture stability differences between healthy people and patients after anterior cruciate ligament reconstruction. The centre of pressure sway was registered using the standard posturography platform (Pro-med). During the test, the subject stood freely with eyes open and closed. In order to determine the stability of the subject, the average velocity of the centre of pressure sway, and the average accretion rate of surface area encircled by centre of pressure, a mean radius of centre of pressure and amount of its displacement were calculated. Parameters measured for the eyes closed posture were significantly greater for people after anterior cruciate ligament reconstruction, while differences between groups for eyes open test were statistically insignificant. This indicates impairment of the somatosensoric posture control system. It should be noted that selected stability indicators: an average velocity of the centre of pressure sway, its anterior-posterior and mediolateral components, a mean radius of centre of pressure and a mean accretion rate of surface area encircled by centre of pressure varied in both groups.

“…Estes estudos indicam que informação sensorial adicional pode ser utilizada de forma contínua, provocando redução da oscilação corporal. Por exemplo, Bonfim et al 7,18 relataram o efeito positivo da utilização de informação sensorial adicional na propriocepção e no controle postural. Nestes estudos, os indivíduos apresentaram uma redução da oscilação corporal em situações de contato com uma barra de toque e em situações com a utilização de informação sensorial adicional proveniente do uso de uma tira subpatelar.…”

O objetivo deste estudo foi investigar o efeito do treinamento sensório-motor, com e sem a utilização de informação sensorial adicional do tipo tira subpatelar, no controle postural de indivíduos sadios. Trinta adultos jovens e sadios participaram deste estudo, divididos aleatoriamente em três grupos: controle (GC), experimental sem informação sensorial adicional (GE) e experimental com informação sensorial adicional (GEI). Os participantes realizaram a tarefa de apoio monopodal, com olhos fechados, sobre uma plataforma de força, em duas condições sensoriais: 1) condição de informação normal - sem inclusão de informação sensorial adicional; e 2) condição de informação adicional - utilização de tira sub-patelar. A partir dos dados da plataforma de força foram calculadas as variáveis: amplitude e velocidade média de oscilação do centro de pressão (CP). Os participantes dos grupos experimentais realizaram dez sessões de treinamento sensório-motor com prancha de equilíbrio, com ou sem a utilização de informação sensorial adicional, de acordo o grupo definido. Os participantes dos grupos experimentais apresentaram redução da amplitude e velocidade média de oscilação do CP após o treinamento sensório-motor (p<0,05). Além disto, foi identificada diferença significante entre os grupos experimentais (p<0,05). Em conclusão, o treinamento sensório-motor melhora o controle postural de indivíduos sadios e estes efeitos são maximizados com a utilização de informação sensorial adicional.

The anterior cruciate ligament (ACL) is one of the most important stabilisers of the knee joint. The key role of ACL is to resist anterior translation of the tibia in relation to the femur. At the same time, ACL does not only perform a mechanical limiting function, but is also an important component of the sensorimotor system. The aim of this study was to assess neuromuscular control in patients after ACL reconstruction by evaluating the maintenance of dynamic balance.Material and methods. Twenty-six patients (aged 28.4±6.3 years) after ACL reconstruction (ACLR group) were enrolled. All patients had undergone arthroscopic reconstruction of ACL, and were recruited to the study 11-13 months after the surgery. Thirty-seven healthy individuals served as a control group (CTRL). The maintenance of the single-leg and two-leg standing position on an unstable surface was assessed using the Biodex Balance System SD.Results. The ACLR group differed from the control group in the values of the overall stability index (p<0.05; 6.53±2.04, and 5.27±1.42, respectively) when stabi...
