SOT (Smart Orthotic Treatment) is a resting splint for the spastic and paretic hand, when the goal is to maintain or increase the mobility of the hand.The orthosis is smooth and lightweight. The S.O.T has an aluminium core which allows adjustment to the desired position. The aluminium core is embedded into polyethylene foam, which is covered with fabric. The brace is delivered in aresting position. A resting position can offer pain relief, relaxation to the hand and it also provides a good biomechanical position that may reduce the risk of flexor shortening of the wrist and fingers.The orthosis anatomic configuration supports the important thenar muscle, the CMC- and MCP joint, which is particularly important for the intended patient groups, when the thumb tends to adduct in the CMC joint and hyperextend in the MCP joint. SOT Resting splint increases the conditions for an effective grip.
