Chii chinonzi chimiro chakanaka?Piripoints: iyo physiological curvature yemuzongoza uye kumanikidzwa kwema discs.
Kana ukanyatsotarisisa muenzaniso weskeleton yemunhu, unoona 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, kuita 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.Chiito ichi chichaita kuti thoracic vertebrae iwedzere kukombama, kukombama 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, unofanirwa kuzviwanira iweergonomic office chair.
Basa guru reergonomic chairndiko kupa rubatsiro rwekutanga rwechiuno nekushandisalumbarrutsigiro.Nekuenzanisa simba, kumashure kunopa S-yakaita curve kuseri kwechigaro, ichideredza kudzvanywa kwe lumbar spine kusvika yave pedyo nekumira kwakajairwa.Pamusoro pekuvapo kwerutsigiro rwechiuno, dhizaini yakakombama yekuseri kwechigaro ichienderana nechimiro chechimiro chemuviri wemunhu musana curvature, zviri nani.
