Problem of research. Joints – important part of human movement apparatus. Therefore joint traumas are a serious problem both from medical and social point of view. In case of mechanical trauma very often knee joint is hurt. Most often young people suffer from traumas, particularly sportsmen when knee joint cruciate ligaments are hurt. In such situations as one of the most effective physioterapical treatment methods cryotherapy is applied. In 2004 in Lithuania particularly low temperature medical CO2 gas (-78 0C) was applied, sprinkled with 50 bar power. Dry bacteriostatic gas which during a very short time of application (30–60 sec) cause thermal shock in tissues – cool down tissues in a very short time from +5 to +2 0C. Theoretical background of cryotherapy and practical experience in Lithuania are not widely described that’s why it is necessary to make more intense research, to generalize its results, to seek for most effective methods of research stimulating faster rehabilitation of patients’ working capacity. Objective of study. Taking into consideration the fact that cryotherapy is very new and very live in Lithuania, it was selected as the theme for Master’s thesis, its objective is to estimate the influence of cryotherapic treatment on the functions of knee joint functions after cruciate ligament reconstruction. Task of study: to evaluate the dynamics of pain intensity experienced by patients, knee joint movement amplitude dynamics, knee joint oedema scope dynamics... [to full text]

Temos aktualumas: Siekiant įvertinti kelio sąnario funkciją po priekinio kryžminio raiščio plyšimo naudojami įvairūs metodai: izokinetinis testavimas dinamometru (Kannus et al., 1992; Risberg et al., 2009), judesio analizė (Risberg et al., 2009), elektromiografija, klinikiniai testai (Irrgang, 2003; Lee et al., 2008) ir klausimynai (Irrgang, 2001; Lee et al., 2008). Ieškodami patikimesnių būdų įvertinti žmogaus nervų- raumenų sistemos valdymo efektyvumą, Kauno technologijos universiteto ir UAB „Katra“ specialistai kartu su Lietuvos kūno kultūros akademija sukūrė naują originalų prietaisą – žmogaus rankų ir kojų judesių dinaminių parametrų analizatorių (DPA–1). Tyrimo objektas: DPA testų patikimumas ir informatyvumas. Tyrimo tikslas: Nustatyti DPA–1 testų patikimumą ir informatyvumą po priekinio kryžminio raiščio rekonstruojamosios operacijos. Tyrimo uždaviniai: 1. Nustatyti DPA–1 testų patikimumą, atliekant standartines ir variabilias užduotis po priekinių kryžminių raiščių rekonstruojamosios operacijos. 2. Nustatyti DPA–1 testų informatyvumą, atliekant standartines ir variabilias užduotis po priekinių kryžminių raiščių rekonstruojamosios operacijos. Tyrimas atliktas Lietuvos kūno kultūros akademijoje „Žmogaus motorikos“ laboratorijoje. Jame dalyvavo 34 tiriamieji, kurie buvo suskirstyti į dvi grupes. Pirmąją grupę sudarė pacientai, patyrę kelio sąnario priekinio kryžminio raiščio rekonstruojamąją operaciją (n=17). Šių tiriamųjų amžiaus vidurkis – 31,3 ± 7,8 metai, ūgis –...

In order to devise more reliable methods to evaluate the efficiency of human neuromuscular control, the dynamic parameters’ analyzer of human’s hands and legs movements (DPA-1, Patent No. 5251; 2005 08 25) was constructed by Kaunas Technology University and „Katra“ engineers in collaboration with Lithuanian Academy of Physical Education. The object of the study: the reliability and validity of DPA-1 testing procedures. The aim of the study is to establish the reliability and validity of DPA-1 testing procedures after anterior cruciate ligaments reconstructive surgery. The goals of the study are the following: 1. To establish the reliability of DPA-1 testing procedures while performing standard and variable tasks after anterior cruciate ligaments reconstructive surgery. 2. To establish the validity of DPA-1 testing procedures while performing standard and variable tasks after anterior cruciate ligaments reconstructive surgery. The recearch was performed in the Laboratory of Human Motorics at the Lithuanian Academy of Physical Education. 34 participants, who were divided into two groups... [to full text]
