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.
Page 5 of 49
User Manual - Version 1.7 Armotion™
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. For this process Reha Technology
AG is dependent on you, as a regular user, for ideas and suggestions.

User Manual - Version 1.7 Armotion™
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.
Page 7 of 49
User Manual - Version 1.7 Armotion™
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*

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.
When spams or alteration of the tone are observed during the therapy on Armotion, it is
recommended to stop the therapy by pressing one of the emergency stop.

The exercise starts when the Armotion is brought to the centre of the work plan. At this point,
after a brief countdown, the patient can go to any of the icons and pausing for 1 second the
cursor circle pencil icon to indicate that it has been selected. Once an icon is selected the patient
is asked to select the corresponding icon.
In this exercise, the patient is completely free to move. The Armotion comes to the aid of the
patient after 25 seconds if no icon is selected. If an icon is already selected, but after 25 seconds
still missing the second to close the association, the Armotion intervenes accompanying the
patient to the associated icon.
The exercise can be interrupted at any time by pressing the “esc”
Choose between two, three or four associations (pairs) and set the following parameters:
Number of repetitions: allows defining the number of rounds in order to complete the exercise
Size: set Small, Medium or Large depending on the range of motion and the anthropometric
dimensions of the patient (the given trajectory will result to be scaled in the work plan)

7.4.7 Scoring and results
All exercise offer a score at the end of the game and detailed results are available directly after
the game has been finished or at a later point from the results overview.
Once completed, the software shows the score and the energy expressed by the patient during
the session.
The score is calculated taking into account the following parameters:
• degree of autonomy of the patient determined at the time of activity: (time spent with
active user in robot moving - time spent with active user in robot stopped) / (total exercise
duration - time spent stationary robot)
• degree of autonomy of the patient's calculated on the work done: work of the patient
along the trajectory / (patient work along the trajectory + working robot along the
trajectory)
• accuracy of the patient work along the trajectory / total work of the patient
• normalized speed: average speed of the patient / ( maximum possible speed x 80 % )
The measured value of the performance would be equal to the sum of the 4 above-mentioned
parameters each multiplied by a weight (currently the weights are all places to 1/4).
Page 41 of 49
User Manual - Version 1.7 Armotion™
Finally, the weighted sum is multiplied by a factor of 10 to obtain a score between 0 and 10.
• between 0 and 4, the test is considered NOT sufficient
• above 4 and up to 6, the test is considered to be sufficient
• over 6 evidence is considered successfully passed ( and the PC speaker will reproduce the
sound of applause )
Once the therapy ends a session manager window opens.
By pressing “start” it is possible to repeat the exercise with the same settings. Click on “esc+ to
return to the main menu.
By clicking on “results” the system shows the following:
