Ukuphakama kwangesikhathi esedlule kubhekise kubungako obubonakala phansi kwesithupha sakho. Yenziwe yimisipha emithathu ehlukene esebenza ukulawula ukunyakaza okuhle kwesithupha.

Sizobhekisisa kahle ukugqama ngaleso sikhathi, ukusebenza kwaso, nezimo ezingase zikuthinte.

Imisipha yokuvelela ngaleso sikhathi

I-Opponens pollicis

I-opponens pollicis iyimisipha emikhulu kunayo yonke etholakala ekuveleni ngaleso sikhathi.

Umsebenzi wawo ubaluleke kakhulu kulokho okwenza izithupha zabantu ziphikisane. I-opponens pollicis isebenza ukuhambisa isithupha kude neminye iminwe yesandla. Ngesikhathi sokunyakaza, isithupha siyajikeleza ukuze siphikisane, noma siwelele, eminye iminwe emine yesandla.

Lokhu kunyakaza kubaluleke kakhulu emisebenzini efana nokubamba nokubamba izinto.

Abductor pollicis brevis

I-abductor pollicis brevis itholakala ngenhla kwama-opponens pollicis ngaphandle kwesithupha. Umsebenzi wawo ukusiza ukuhambisa isithupha kude nomunwe wenkomba.

Lokhu kuhamba kungakhonjiswa uma isandla sibekwe siphezulu ebusweni bese isithupha sisuswa kude nesandla.

I-Flexor pollicis brevis

I-flexor pollicis brevis nayo itholakala ngaphezu kwe-opponens pollicis kodwa itholakala ngaphakathi kwesithupha. Inesibopho sokugoba isithupha ngasesiphinki.

Lokhu kuhamba kungakhonjiswa ngokugoba ilunga lokuqala lesithupha. Uma lokhu kwenzeka, isithupha kufanele sigobe ukuze sikhombe ngasemunweni obomvana.

Umdwebo we-Anatomy

Chofoza kwimisipha yesithupha ukubona i-opponens pollicis, i-abductor pollicis brevis, ne-flexor pollicis brevis.

Imizwa yokuvelela ngaleso sikhathi

I-median nerve inikeza imisipha kuyo yomithathu imisipha ekuphakameni okwenzeka ngaleso sikhathi. Le nerve median ivela eqenjini lezinzwa elibizwa ngokuthi i-brachial plexus.

I-median nerve ihamba ngaphakathi kwengalo lapho ekugcineni iwela khona endololwaneni, inikezela izinzwa emisipheni yengalo, esihlakaleni nasesandleni.

Ingxenye encane ye-flexor pollicis brevis, ebizwa ngokuthi ikhanda elijulile, inikezwa izinzwa yi-ulnar nerve. Ngokwengeziwe, i-opponens pollicis inikezwa izinzwa yi-ulnar nerve cishe kubantu abangamaphesenti angama-20.

Njenge-nerve median, i-ulnar nerve ivela ku-plexus ye-brachial. Yehlisa ingalo, yeqe indololwane eceleni kwesici sangaphakathi bese ihamba ngaphakathi kwengalo. Inikeza nezinzwa ezingxenyeni zengalo, isihlakala, nasesandleni.

Umsebenzi wokuvelela ngaleso sikhathi

Usosayensi uJohn Napier wake wathi, "Isandla ngaphandle kwesithupha asinto yalutho ngaphandle kwe-animated spatula futhi okungenani i-forceps amaphuzu ayo angahlangani kahle." Ngempela, isithupha sibaluleke kakhulu ezindleleni esihlangana ngazo nezinto ezisemvelweni.

Ukuphakama okwenzeka ngaleso sikhathi kusiza ukulawula ukuhamba okuhle kwesithupha, kufaka phakathi ukukwazi ukubamba, ukubamba, nokuncina izinto.

I-abductor pollicis brevis kanye ne-flexor pollicis brevis zivumela ukunyakaza kwesithupha kude noma ukuya kweminye iminwe yesandla. Ama-opponens pollicis enza isithupha sikwazi ukuphikiswa. Lokhu kuhamba kusivumela ukuthi siphathe ngokucophelela futhi sisebenzise izinto nezinto.

Izimo ezithinta ukuvelela ngaleso sikhathi

Kunemibandela eminingana engathinta ukuphakama okwenzeka ngaleso sikhathi, okuholele ekwehleni kokusebenza noma nasekucineni kwemisipha.

Ungahle ubhekane nenkinga ngemisipha yokuvelela ngaleso sikhathi uma uqaphela:

• Ubuntofontofo noma "izikhonkwane nezinaliti" kusithupha sakho. Lezi zinzwa zivame ukubangelwa ukucindezela noma ukucindezela kwi-nerve median.
• Ubuthakathaka bemisipha. Abantu abanemisipha yokuphakama ebuthakathaka bangabamba izinto ngokuzwakalayo futhi bathambekele ekuzilahleni.
• Ubuhlungu. Ubuhlungu obuningi obuhlobene bungaphuma kusukela phansi kwesithupha.
• Ukukhubazeka. Uma ukuqaphela lokhu ezansi kwesithupha sakho, kungabangelwa yi-atrophy yemisipha yokuvelela ngaleso sikhathi.

Ezinye izibonelo zezimo ezingathinta ukuphakama ngaleso sikhathi zifaka:

• I-Carpal tunnel syndrome. Lesi simo sidalwa ukucindezelwa noma ukucindezelwa komthambo ophakathi njengoba ugijima esihlakaleni. Izimpawu ezivamile zifaka ukuba ndikindiki, ukuncinza nobuthakathaka.
• I-basal isithupha samathambo. Lesi simo singenxa yokuwohloka koqwanga oluzungeze ilunga lesithupha elingezansi. Ngenkathi kuthinta amalunga azungeze ubukhulu besikhathi esedlule hhayi imisipha uqobo, isimo singadala ukulahleka kokunyakaza noma ubuthakathaka besithupha.
• Ukuhlukumezeka kwengalo, isihlakala, noma isithupha. Ukulimala engalweni engezansi kungabeka abantu ezimeni zezinzwa noma ze-arthritic ezingathinta ukuvelela ngaleso sikhathi. Isibonelo, ukuphuka kwengalo eyonakalisa i-nerve median kungaholela ekwehliseni umuzwa endaweni yesithupha.
• IMisa noma isimila. Isisindo noma isimila endaweni ephakeme noma ezungezile ayivelakancane. Lapho ekhona, lokhu kungadala izimpawu ezifana ne-carpal tunnel syndrome.
• I-Amyotrophic lateral sclerosis (ALS). I-ALS yisifo sesimiso sezinzwa esinciphisa kancane kancane imisipha yomzimba. I-Atrophy yezingxenye zobukhulu obukhona ngaleso sikhathi iwuphawu lokuqala lomtholampilo lwe-ALS.

Ukuzivocavoca kwe-Thenar

Zama izivivinyo ezingezansi ukuze ugcine amandla okuvelela ngaleso sikhathi. Uma ungaqiniseki nganoma yikuphi kwalokhu kuvivinya umzimba noma usanda kulimala noma uhlinziwe engalo yakho, esihlakaleni, noma esandleni, khuluma nodokotela wakho kuqala.

Isithupha se-flex and extension

Phakamisa isandla sakho, uqiniseke ukuthi isithupha sakho sibekwe kude neminwe yakho. Hambisa isithupha sakho entendeni yesandla sakho ukuze sithinte ngezansi nje komunwe wakho obomvana.

Bamba indawo ngayinye imizuzwana eyi-10 kuye kwengu-15, wenze ama-reps ayi-10 ngesandla ngasinye.

Isandiso sesithupha ngebhande lenjoloba

Beka isandla sakho usibeke phezu kwetafula noma kwenye indawo eqinile. Beka ibhande lenjoloba esandleni sakho ukuze lihlale phansi kwamalunga omunwe wakho. Ngobumnene susa isithupha sakho kude neminye iminwe yakho lapho ingafika khona. Bamba lesi sikhundla imizuzwana engama-30 kuye kwangama-60 bese uyadedela.

Phinda izikhathi eziyishumi kuye kwezingu-15 ngesandla ngasinye.

Ukuzivocavoca ngokubamba ngesandla

Thatha ibhola lomphebezo noma elilinganayo ngesandla esisodwa. Cindezela ibhola kanzima ngangokunokwenzeka phakathi kwemizuzwana emi-3 nengu-5 ngaphambi kokuyekelela kancane ukubamba kwakho.

Phinda lokhu izikhathi eziyi-10 kuye kwezingu-15 esandleni esisodwa bese ubamba ngesinye isandla.

Ncinza amandla okuzivocavoca

Thatha ibhola elithambile eliphakathi kwesithupha sakho nomunwe wenkomba. Ncinza ibhola, ubambe indawo phakathi kwemizuzwana engama-30 nengu-60. Khipha kancane ingcosana.

Phinda izikhathi eziyi-10 kuye kwezingu-15 ngesandla esifanayo uphinde nangesinye isandla.

Ukuthinta isithupha

Phakamisa isandla sakho phambi kwakho. Thinta ngobumnene isithupha sakho komunye weminwe yakho emine, ubambe indawo ngayinye imizuzwana engama-30 kuye kwangama-60.

Phinda okungenani amahlandla ama-4 engalweni ngayinye yesandla sakho.

Ukuthatha

Ukuphakama kwangesikhathi siyiqembu lezicubu ezintathu ezincane ezansi kwesithupha. Naphezu kobukhulu bawo obuncane, zibaluleke kakhulu ekulawuleni ukunyakaza okuhle kwezithupha ezifana nokubamba nokuncinza.

Ukuphakama kwaleso sikhathi kungathinteka yizimo ezahlukahlukene ezingaholela ekwehleni kobubanzi bokuhamba noma ukusebenza kwemisipha. Uma ukholwa ukuthi uhlangabezana nezimpawu ezihambisana nenye yalezi zimo, yenza i-aphoyintimenti yokubona udokotela wakho.
