A joint mobilization apparatus includes a pulling unit and a power unit. The pulling unit includes a wearable member set for mounting on the patient's joint part, and a rope set connected to the wearable member set. The power unit provides power of reciprocatingly pulling the rope set, and includes a shell member, a motor, and a reciprocation mechanism connected to the motor and the rope set. The reciprocation mechanism is driven by the motor to reciprocate relative to the shell member, so as to pull the rope set to reciprocate the wearable member set and patient's joint part. By using the power unit to drive the pulling unit to pull reciprocatingly for mobilizing the patient's joint part, instead of the therapist's treatment, the therapist's burden in physical strength can be reduced. Furthermore, the joint mobilization apparatus can provide the user to execute various muscle training modes.一種關節鬆動設備，包含一牽引單元，及一動力單元。該牽引單元包括一用於套設在患者的關節部位的套具組，及一連接該套具組的拉繩組。該動力單元用來提供該拉繩組往復拉放的動力，該動力單元包括一殼體、一設置於該殼體的馬達，及一設置於該殼體且連接該馬達及該拉繩組的往復機構，該往復機構用於受馬達驅動而相對於該殼體往復移動，以牽引該拉繩組拉動該套具組及患者的關節部位往復移動。藉由該動力單元帶動該牽引單元往復拉放，可代替治療師對患者的關節部位進行施力鬆動，以減輕治療師體力負擔之外，亦可供患者自行使用。
