The present invention relates to a robotic arm and a method of using this robotic arm. The present invention more specifically relates to a robotic arm which can be used in upper limb training.

In upper limb training, a patient or user trains his or her arms to improve or regain control over them. It is especially used for patient’s suffering from a partial paralysis. A partial paralysis may be caused by any of a number of common causes: multiple sclerosis, a tumour or an accident. The most common cause of partial paralysis however is a stroke. Patients suffering from partial paralysis may benefit from upper limb training in which a physiotherapist may subject a patient’s arm repeatedly to a certain movement. Various treatment methods exist. Proprioceptive Neuromuscular Facilitation (PNF) is one of these methods and aims at stimulating a patient’s proprioreceptors. It is possible for a patient to retrain their brain to perform certain movements and in this way regain some functional control over their arms. This therapy has the best results only when the movement of the arm is repeated at least twice a day for 45 minutes during a month. It is not always possible to give each patient this care during such an extended period.
