A device for the treatment of adhesive capsulitis in a joint of a patient, the device being a portable, hand-held appliance and comprising: a) a driven manipulation effector adapted to engage an arm of the patient in order to manipulate the patient's joint, wherein the device is adapted such that the manipulation effector moves in accordance with a point-to-point motion profile; b) a driven oscillator, wherein the driven manipulation effector is coupled to the driven oscillator and adapted to manipulate the joint, and wherein the driven oscillator is adapted to displace the driven manipulation effector in accordance with the point-to-point motion profile; c) a motor coupled to a power supply and adapted to drive the driven oscillator, and a drive shaft coupling the motor and the driven oscillator; d) a body coupling the driven oscillator to the driven manipulation effector; and e) an anchor adapted for securement of the body to a secure object to enable the driven manipulation effector to manipulate the patient's joint; the device being characterised in that: the driven oscillator is mechanically coupled to the drive shaft at an attachment point offset from the axis of the drive shaft and adapted to impart a rotational motion upon the driven oscillator when the motor is in use, and in that the manipulation effector is adapted to move in a point-to-point motion profile including: i) a first phase of motion under constant acceleration; ii) a second phase of motion under zero acceleration; and iii) a third phase of motion under constant deceleration. a) a driven manipulation effector adapted to engage an arm of the patient in order to manipulate the patient's joint, wherein the device is adapted such that the manipulation effector moves in accordance with a point-to-point motion profile; b) a driven oscillator, wherein the driven manipulation effector is coupled to the driven oscillator and adapted to manipulate the joint, and wherein the driven oscillator is adapted to displace the driven manipulation effector in accordance with the point-to-point motion profile; c) a motor coupled to a power supply and adapted to drive the driven oscillator, and a drive shaft coupling the motor and the driven oscillator; d) a body coupling the driven oscillator to the driven manipulation effector; and e) an anchor adapted for securement of the body to a secure object to enable the driven manipulation effector to manipulate the patient's joint; the device being characterised in that: the driven oscillator is mechanically coupled to the drive shaft at an attachment point offset from the axis of the drive shaft and adapted to impart a rotational motion upon the driven oscillator when the motor is in use, and in that the manipulation effector is adapted to move in a point-to-point motion profile including: i) a first phase of motion under constant acceleration; ii) a second phase of motion under zero acceleration; and iii) a third phase of motion under constant deceleration. the driven oscillator is mechanically coupled to the drive shaft at an attachment point offset from the axis of the drive shaft and adapted to impart a rotational motion upon the driven oscillator when the motor is in use, and in that the manipulation effector is adapted to move in a point-to-point motion profile including: i) a first phase of motion under constant acceleration; ii) a second phase of motion under zero acceleration; and iii) a third phase of motion under constant deceleration. i) a first phase of motion under constant acceleration; ii) a second phase of motion under zero acceleration; and iii) a third phase of motion under constant deceleration.
