A wearable gait rehabilitation training device and a gait training method using the same are disclosed. The wearable gait rehabilitation training device includes a support member, an electric power supply unit, a light source providing unit and a trigger unit, in which the support member is attached on a user's lower limb, the electric power supply unit and the light source providing unit are coupled with each other and disposed on the support member, and the trigger unit is contacted with a foot sole of the lower limb on which the support member is attached and is coupled to the light source providing unit. The trigger unit is triggered when the foot sole is landed, and the light source providing unit is activated by the trigger unit to project a visible light onto the ground where a front stepping point of user's opposite lower limb is located. Accordingly, a stepping prompt point with a visible prompt effect can be provided on the ground, and the user's opposite side leg can be guided to step on the stepping prompt point with reference to the stepping prompt point.一種穿戴式步態復健訓練裝置及使用該裝置之步態訓練方法，包括：於一支撐件上設耦合的一電力提供單元及一光源提供單元，該支撐件依附於一使用者的下肢；一觸發單元接觸該支撐件所依附之下肢的足底，該觸發單元與該光源提供裝置耦合；該觸發單元於該足底著地時被觸發，該光源提供裝置被該觸發單元啟動，將一可見光投向該使用者之對側下肢的前方跨步點之地面，於該地面形成一具有視覺提示效果的跨步提示點，使用者參考該跨步提示點將對側腳踩在該跨步提示點上。
