연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The rehabilitative training device of claim 1, wherein there are four sets of linkages, levers and biasing members, one set for each finger of the affected hand, the sets being disposed adjacent one another in a side-by-side manner. 10. The rehabilitative training device of claim 1, further including a locking mechanism for releasably locking and disabling the lever and prevent pivoting thereof. 11. The rehabilitative training device of claim 10, wherein the locking mechanism includes an upstanding frame coupled to the base and a slidable locking member which moves between a locked position in which the locking member engages and locks the lever and a retracted position in which the locking member is spaced from the lever, thereby permitting the lever to freely pivot. 12. The rehabilitative training device of claim 1, wherein the first support comprises a second cross bar that is fixed to and extends across the first arm platform assembly. 13. The rehabilitative training device of claim 1, wherein the second cable attaches to a top side of the second finger restrainer and the linkage attaches to an underside of the second finger restrainer. 14. A finger rehabilitative training device for use by a patient comprising: a base;first and second arm platform assemblies that are coupled to the base and include support surfaces for left and right arms of the patient to be placed, the first and second arm platforms being positionable between a first position in which the left hand comprises an affected hand and the right hand comprises a non-affected hand and a second position in which the left hand comprises a non-affected hand and the right hand comprises an affected hand, wherein the first and second arm platforms are disposed adjacent one another in a side-by-side manner;a first finger restrainer for being coupled to at least one finger of the non-affected hand;a second finger restrainer for being coupled to at least one finger of the affected hand;a first cross bar that is pivotal about a pivot point and extends across at least a portion of the first and second arm platform assemblies;a first cable attached between the first finger restrainer and a first end portion of the second cross bar such that when the respective finger of the non-affected hand is raised, the first cross bar pivots about the first pivot point;a second cable attached between the second finger restrainer and a second end portion of the first cross bar such that when the first cross bar pivots in either a counterclockwise or clockwise direction, the first end portion pivots in a first direction, while the second end portion pivots in an opposite second direction resulting in synchronized movement between the at least one finger of each of the non-affected hand and the affected hand; anda counter force mechanism that provides resistance and provides a return force that counters pivoting of the first cross bar and returns the first cross bar to a rest position, the counter force mechanism being coupled between the second finger restrainer and the base and being configured to generate the return force when the raising of the finger of the non-affected hand is completed and the finger of the non-affected hand is free to be lowered, whereby the counter forcer mechanism provides an active motion of the at least one finger of the affected hand causing the finger of the affected hand to be lowered, thereby causing the first cross bar to pivot and be free to return to the rest position without any active force being applied by fingers of the non-affected hand. 15. The finger rehabilitative training device of claim 14, wherein the first end portion of the first cross bar includes a plurality of first cable coupling members that are spaced apart and positioned such one first cable coupling member corresponds to one finger of the non-affected hand, the first cable being coupled to one of the first cable coupling members and then routed underneath a bottom elongated shaft before terminating at the first finger restrainer so as to cause the first finger restrainer and the first end portion to move in inverse directions and the second end portion includes a plurality of second cable coupling members and a plurality of third coupling members located on an opposite face of the second end portion relative to the second coupling members, wherein one of the plurality of second and third cable coupling members faces downward towards the counter force mechanism. 16. The rehabilitative device of claim 14, wherein the counter force mechanism including a set of biased linkage assemblies, one for each finger of the affected hand, each biased linkage assembly including a linkage member that is connected between the second finger restrainer and a respective pivotable lever, the pivotable lever being attached to the base with a spring that generates the return force to: (1) return the lever to a rest position after the lever pivots upwards due to pivoting of the first cross bar, and (2) return the second finger restrainer to a rest position. 17.
