Chii chinonzi chimiro chakanaka?Piripoints: iyo physiological curvature yemuzongoza uye kumanikidza pama discs.
Kana ukanyatsotarisisa muenzaniso weskeleton yemunhu, uchaona kuti nepo musana wakatwasuka kubva kumberi, divi rinoratidza kaS-curve kakarebeswa kureba, yatinoti physiological curve.
Muzongoza wemunhu mukuru wakaumbwa ne24 cylindrical vertebrae inopindirana, sacrum, uye tailbone.Majoini ecartilaginous pakati pema vertebrae maviri ari pedyo anonzi intervertebral discs.Kukosha kwe intervertebral disc, chaizvoizvo, ndeyokuita kuti vertebrae ive nehumwe chiyero chekufamba, iyo inoratidza kukosha kwayo.
Iwe unofanirwa kunge wakasangana neizvi:apoakagara, muviri usingazivi uchirembera, kusvikira chiuno chakamira zvachose "chakanamira" pachigaro,uye neweuchaona kuti musana warasa kukombama kwawakaitarinhitouchingbac yakok.Panguva ino, kudzvinyirirwa kusina kujairika kunoparadzirwa pane disc.Mukufamba kwenguva, ichaigumbura, nokudaro inokanganisa chiyero chebasa re vertebrae, migumisiro inogona kufungidzirwa.
Vamwe vanhu vanofarira kuisa maoko avo pamberi pekombuta vopeta.Ichi chiito chichaita kuti musana wechipfuva uwedzere kukombama, kupeteka kwemutsipa wekervical kunova kudiki, izvo zvinoita kuti lumbar curve ive diki uye yakanyanya kutwasuka.Kwenguva yakareba, izvi zvinogona kukonzera matambudziko emudumbu.
Iyo inonzi yakanaka yekugara kumira ndeyekuchengetedza yakajairika physiological curvature yemuzongoza wemuviri, kuburitsa yakanyanya kudzvanywa, yakagoverwa pane intervertebral disc pakati pe vertebrae, panguva imwe chete, kugovera kwakakodzera uye yunifomu static mutoro. pazvinyama zvakabatanidzwa.
Mukuwedzera kune kumira kwakanaka, iwe unofanirwa kuzviwanira iweergonomic office chair.
Basa guru reergonomic chairndiko kupa rubatsiro rwekutanga rwechiuno nekushandisalumbarrutsigiro.Nekuenzanisa simba, kumashure kunopa S-yakaita curve kumashure kwechigaro, ichideredza kudzvanywa kwe lumbar spine kusvika yave pedyo neyakajairwa yakamira.Pamusoro pekuvapo kwerutsigiro rwechiuno, dhizaini yakakomberedzwa yekuseri kwechigaro ichienderana nechimiro chemuviri wemunhu musana wemusana, zviri nani.
