m Topicality of the proble
Prosthesis in orthopaedic te chniq ue are co nstr uction s t hat act as le g
fu nctio n reproduction a nd for external nor m al vie w o f the l eg. It i s a tech niq ue
giv in g a possibilit y to adapt t o the societ y a nd li ve a f ull - fl edged life, w he n o ne
or another li mb is lost.
By the data, declared by t he w orld hea lth societ y , people w it h a disabilit y
incl ude 10 % of all ulation, aworld pop m on g t he m people over 80 years old.
More and more ort hopaedic tech nique s are produced i n Lit h uania at
present. The production, ma n ufac tured in our cou ntr y keep s in step w it h w orld
desig n and qualit y i n forei gn countries a nd the y are 5–6 ti me s cheaper. The
m ai n ai m of the desi gner s a nd con structors of orthopaedic tech niq ues is to
desig n and produce func tion al and hig h qualit y lo w er limb s prosthes is and
apparatus.
In the mea nti m e, the sa m e as abroad, in Lith ua nia the production processes
of t he prosthe sis are auto m ate d but not so m u ch to en sure a good qualit y o f t he
prosthesis. So me ti m es i t is v ery hard to m ake prosthes is o f adequate size to a
patient that prost hesi s i m plici tl y f its just to the patie nt. Als o, it is ver y hard to
adjust it, ensuri ng t he sa me l engt h as the resid ual li mb w h ich sho uld precisel y
correspond to the lost li mb of the c han geable loads chai ns of t he prosthe sis
periodically are defor m ed du ring w a lki n g. In other w ords , the len gt h of t he
prosthesis c han ge s durin g gai t . Thus, it is ver y i m portant to set the li m it s of the
chan gi ng prost hesi s len gt h.
Errors, w hic h appear during the production of t he prosthe sis, a nd elasti c
defor m ation s of t he prosthes is lin ks ha ve a direct inf lue nce on the di sabled
hu m a n ga it s m ooth nes s and t h e position of t he ma ss ce ntre. When t he prosthes is
is inacc urate, a h u m an feel s bad, pain appears in differen t parts of the bod y,
especiall y in t he back i n t he tru nk area and pelvi s. Scoli osis cou ld possibl y
develop, as the positio n of th e mas s ce ntre cha n ges a nd dif ferent de for m ation s
appear as the forces of the m a ss cen tre and reaction start to act.
Aims and tasks of the research
The ai m o f the research is the le g prosthesi s o f a h u m an, w ho se gait
s m ooth ne ss is in fl uenced b y t he leg prost hesi s ma n u facturi ng errors and elas tic
defor m ation s of t he material s.
The mai n tas k s are as follo w s:
to set t he require me nt s, t hat wo uld e ns ure t he h u m an g ait s m ooth nes s,
w h ic h wo uld reduce fatig ue and increase worki n g capacit y of the disabled,
w it ho ut increas in g t he production costs.
GENERAL CHARAC5 SSERTATION •TERISTIC OF THE DITo evaluate ant hropo metrical parame ters of the disabled person and to
determ ine per m i ssible variat ions of t he ma nu fact uri ng a nd asse mb l y errors and
elastic defor m a tions o f the le g prosthesis li n ks.
analTo yse t he i nf lue nce of the m an u fact urin g errors and elastic
defor m ation s on t he disabled hu m a n gait s m ooth nes s a nd t o set possibil ities of
their in ter-co mpe nsat ion.
To develop engineeri n g m et hodolog y to calcula te le g pr osthes is m a n u-

Scientific novelty
The theory o f the disabled h u m an ’ s gait has bee n developed, by addin g:
Li near a nd no n- linear stat ical l y u nsol vable m athe m at ical model s, used to
determ ine t he m ain ratio nal parameter s of t he leg prost h esis, i nfl ue nci ng t he
disabled hu m an gait un s m oot h ness, a nd approxi mate me tho ds to solve the m .
