The Effects of Kinesiology Tape on Static Postural Control in Individuals with Functional Ankle InstabilityLy, Kien Trung 03 September 2020 (has links)
Functional ankle instability (FAI) is characterized by the recurrent giving way of the ankle and the constant feeling of instability that affects the quality of life of its patients adversely. Kinesiology Tape (KT), differed from the traditional rigid athletic tape, becomes more popular as a new therapeutic tool for injuries management. It is reported to decrease pain, promote blood circulation and natural healing of muscular functioning. However, scientific evidence of KT’s effects on FAI remains very limited. Therefore, the purpose of the present study was to investigate if applying KT on the unstable ankle may improve static postural control in individuals with FAI. Twenty young adults with FAI performed a series of static quiet bipedal and unipedal stances on a force platform. Postural control was assessed by four measures derived from the centre of pressure (COP) data: 95% Confidence ellipse of total displacements (area), standard deviation of displacements (SD), mean velocity and mean power frequency (MPF). Measurements were taken at three different times: baseline or no tape, immediately after the application of KT on the unstable ankle, and 24 hours after the taping application with the tape remaining on the ankle. Results revealed only minor changes in mean velocity and MPF in unipedal stances immediately after KT application. However, the overall results indicated statistically insignificant improvements in postural control performance neither immediately after KT application nor after 24 hours. In conclusion, our results suggest that the use of KT did not affect bipedal and unipedal stances of individuals with functional ankle instability.

Interactions visuo-proprioceptives dans les pathologies dégénératives du rachis cervical relevant d'un traitement chirurgical / Visuo-proprioceptive interactions in degenerative cervical spine diseases requiring surgeryFreppel, Sébastien 12 December 2013 (has links)
La proprioception cervicale joue un rôle important dans le contrôle postural, mais la nature exacte de sa contribution est controversée. Dans certains cas de « coup du lapin », une atteinte posturale a été démontrée, sans que l'atteinte du rachis cervical puisse être tenue pour seule responsable. Malgré la forte prévalence des pathologies cervicales dégénératives, leurs conséquences posturales ont été peu étudiées dans la littérature scientifique. Il n'existe aucune publication centrée sur les deux types de pathologie responsables de névralgies cervicobrachiales : les hernies discales cervicales et l'arthrose cervicale. Cette étude a eu pour but d'évaluer le contrôle postural de deux groupes de patients présentant une pathologie cervicale dégénérative avec et sans stimulation optocinétique avant et après traitement chirurgical. Dix-sept patients présentant une radiculalgie ont été inclus dans cette étude et répartis en deux groupes selon l'origine arthrosique ou discale de la compression neurologique. Tous les patients ainsi que 31 témoins ont été soumis à un examen de posturographie statique comprenant 12 enregistrements : les quatre premiers enregistrements ont été réalisés la tête dans l'axe (à 0°) : yeux fermés, yeux ouverts sans stimulation optocinétique, yeux ouverts avec stimulation optocinétique dans le sens horaire, puis antihoraire. Ces quatre situations sensorielles ont été répétées tête tournée 30° à gauche, puis 30° à droite. Les patients ont à nouveau été soumis à ces 12 enregistrements six semaines après l'intervention. Aucun patient ne s'est plaint de sensations vertigineuses que ce soit en pré ou en postopératoire. Avant intervention, les yeux fermés, le groupe hernie discale était plus stable que le groupe arthrose. Après intervention, la contribution visuelle au contrôle postural avait diminué dans les deux groupes dans un environnement visuel dynamique, alors que dans un environnement visuel stable, elle n'avait diminué que dans le groupe arthrose. L'importance relative des informations visuelles et proprioceptives pour le contrôle postural varie selon le type de pathologie et la chirurgie tend à réduire la contribution visuelle surtout pour les patients présentant une arthrose cervicale / Cervical proprioception plays a key role in postural control, but its specific contribution is controversial. Postural impairment was shown in whiplash injuries without demonstrating the sole involvement of the cervical spine. The consequences of degenerative cervical spine diseases are underreported in posture-related scientific literature in spite of their high prevalence. No report has focused on the two different mechanisms underlying cervicobrachial pain: herniated discs and spondylosis. This study aimed to evaluate postural control of two groups of patients with degenerative cervical spine diseases with or without optokinetic stimulation before and after surgical treatment. Seventeen patients with radiculopathy were recruited and divided into two groups according to the spondylotic or discal origin of the nerve compression. All patients and a control population of 31 healthy individuals underwent a static posturographic test with 12 recordings; the first four recordings with the head in 0° position: eyes closed, eyes open without optokinetic stimulation, with clockwise and counter clockwise optokinetic stimulations. These four sensorial situations were repeated with the head rotated 30° to the left and to the right. Patients repeated these 12 recordings 6 weeks postoperatively. None of the patients reported vertigo or balance disorders before or after surgery. Prior to surgery, in the eyes closed condition, the herniated disc group was more stable than the spondylosis group. After surgery, the contribution of visual input to postural control in a dynamic visual environment was reduced in both cervical spine diseases whereas in a stable visual environment visual contribution was reduced only in the spondylosis group. The relative importance of visual and proprioceptive inputs to postural control varies according to the type of pathology and surgery tends to reduce visual contribution mostly in the spondylosis group
