摘要：
A rotational joint of intra-extra rotation (100) for assistance of the movement of intra-extra rotation of a shoulder of a user, said rotational joint (100) comprising a first circular guide (110) arranged to rotate about a rotation axis r, a second circular guide (120) arranged to rotate about a rotation axis r′； parallel to the rotation axis r, an support element (130) arranged to support the first and the second circular guide (110, 120). The first and the second circular guide (110, 120) are pivotally connected by a conical wheel (140) having rotation axis s perpendicular to rotation axes r and said conical wheel (140) being pivotally constrained to the support element (130). When the conical wheel (140) makes a rotation θ about its rotation axis s, the first circular guide (110) makes a rotation φ about its rotation axis r and, at the same time, the second circular guide (120) makes a rotation φ′；=αφ about its rotation axis r′；.
