User Manual - Version 1.7 Armotion™ Page 5 of 49 2 The Armotion™ 2.1 General The Armotion is an innovative robotic solution in the treatment of severe and moderate neurological and orthopaedic dysfunction of the upper extremity. The Armotion`s unique force feedback and force multiplier features detect and react on patient movements, maximizing the effect of each therapy session. The combined recording of kinematic (speed and direction) and dynamic (force interaction by the patient) parameters allow a precise quantitative evaluation and constant monitoring of patient progress. The patient’s cognitive ability is enhanced by multiple functional ADL-related game types and a unique active assistive therapy option. The substantial reduction in size, its portable and compact design and state of the art technology makes the Armotion an easy to use device for the rehabilitation of the upper extremities. The wireless connection to the computer, the rechargeable batteries and the short and simple setup and quick start of therapy further contribute to an optimized allocation of the hospitals resources on a daily routine. The Armotion can easily be employed both in the treatment of severe and moderate neurological dysfunctions (i.e. post stroke recovery) as well as in the rehabilitation of orthopaedic conditions.
User Manual - Version 1.7 Armotion™ Page 6 of 49 Patients exhibiting deficits in the range of motion and strength of the shoulder and elbow with or without minor cognitive deficits related to recognition, find the use of Armotion an innovative solution for a prompt functional recovery. 2.2 Manufacturing and Optimization The Armotion was designed and developed by Humanware S.r.l. and Reha Technology AG in cooperation with the medical University of Pisa, Italy. Reha Technology AG is interested in continual optimization of the practical use of the therapy on patients and improvements to ease of operation of its devices.

User Manual - Version 1.7 Armotion™ Page 7 of 49 3 Safety Instructions This chapter provides an overview of all important safety aspects for the safe and proper operation of the Armotion. 3.1 Intended Use Only when used according to the specifications of the user manual, the operating safety can be guaranteed. The Armotion is intended only for use on patients with severe and moderate motor disorder of the upper extremities – shoulder and elbow. Dedicated software, with numerous exercises, allows the therapist to choose the ideal protocol according to the patient’s dysfunction and therapeutic goal. The software records and evaluates each exercise done by the patient The fields of application include: • Neurological Rehabilitation • Post-traumatic rehabilitation • Orthopaedic and after surgery rehabilitation The Armotion also finds applications in those patients without force and / or without anti-gravity abilities (i.e. patients who are unable to lift the arm/shoulder). The use of the Armotion in the rehabilitation of the upper extremities has shown clinical effectiveness in the treatment of patients with damage to the central nervous system (i.e. post stroke recovery) and in patients with neurodegenerative syndromes and polyneuropathies. . . As mentioned it may be particularly useful for those patients with serious motor limitations that therefore could not be treated with conventional occupational therapy. The Armotion is a medical device according to CE class 2a and therefore it shall be used with a prescribed physical therapy.
User Manual - Version 1.7 Armotion™ Page 8 of 49 Given the mentioned application areas of use, the practitioner defines the intended use and mode of administration of therapy depending on the severity of the disease and diagnosis. The system may not be operated by non-qualified personnel! Accidents and injuries due to ignorance and misuse • Read the user manual NOTICE Any additional and / or different use of the Armotion is prohibited and is considered to be improper. 3.2 Contraindications As it is the case with any other therapy, the treating physician is responsible for compliance with the indications. 3.2.1 General contraindications • Unstable fractures of the upper extremity: do not carry out any therapy on patients with unstable fractures or fractures which have not yet suitably consolidated. • Heavy Osteoporosis: there might be a danger of fractures. • Skin problems: Before and after each therapy make a visual check for existing wounds or pressure points and for ones which may have been caused by the therapy. • Cooperation: whether or not a therapy on the Armotion can be carried out on patients with reduced cooperation, psychotic illnesses or neurotic dysfunctions has to be carefully considered in each individual case. • Spasticity: Modified Ashworth Scale >3*
User Manual - Version 1.7 Armotion™ Page 9 of 49 Please note that other contraindications which are not listed here may be present in your patients. If anything is unclear, or if you have feedback please contact Reha Technology AG. (See contact details on the last page). 3.2.2 Spasticity management Clinical studies confirms that active movement training does not result in increased hypertonia, but results in spasticity reduction in antagonist muscles by activating the reciprocal inhibition mechanism. Furthermore robot –mediated therapy contributes to a decrease in motor impairment of the upper limbs in subjects with chronic hemiparesis, resulting in a reduction on shoulder pain.** Clinical observation show how Armotion can accommodate neuromuscular abnormalities associated with spastic joint evaluated on a Modified Ashworth Scale Bohannon & Smith value: < or = 3. As a general indication we recommend either both manual gentle muscle stretching techniques (i.e conventional muscle stretching, muscle reinforcement, physical agent and pain management techniques) prior to the training on Armotion.
