Plain English Summary
Background and study aims
A stroke occurs when the blood supply is cut off to the brain. A majority of stroke patients are affected by an impaired function of the upper extremity (upper body and arms). Numerous studies have indicated that there is a relationship between intensity and amount of training on the one hand and improvement of functions on the other hand. Usually, patients with a severe paresis (muscle weakness) of the upper extremity are treated with the ArmeoSpring exoskeleton during their inpatient rehabilitation. An exoskeleton is a frame that is put on the arm to help support the arm weight and help improve function. The aim of this study is to examine what happens when treatment time with this device is increased without investing additional personnel.
Who can participate?
Stroke patients aged 18 to 85
What does the study involve?
Participants receive 24 training sessions with the exoskeleton over four weeks. This is connected to a computer that offers virtual reality. The degree in which they can move their arm while in the exoskeleton is recorded.
What are the possible benefits and risks of participating?
Participants may benefit from improvements in motor function. The device is safe and has a certificate allowing to use it for patient treatment. There are no known risks.
Where is the study run from?
Kliniken Schmieder (Germany)
When is the study starting and how long is it expected to run for?
February 2016 to February 2017
Who is funding the study?

Using an upper extremity exoskeleton for semi-autonomous exercise during inpatient neurological rehabilitation- a pilot study
A self-contained robot-assisted training in addition to conventional inpatient rehabilitation is feasible.
University of Constance, 21/04/2016
An interventional study with the ArmeoSpring exoskeleton used as a device for additional self-contained training in evenings and on weekends. The study explores feasibility and acceptance. It is single-centre because it is a pilot study

Participants receive self-contained training with the Armeo Spring exoskeleton over a period of four weeks with up to 24 treatment sessions.
The exoskeleton is connected to a computer that offers a variety of games in a virtual reality environment. For example, patients can paint a room, can grasp objects in a supermarket, can catch balls and so on. The degree to which the patients can move the arm while it is positioned in the exoskeleton is determined. Movements visible on the screen are adjusted to this individual level of performance.
There is no follow up.
Primary outcome measure
Feasibility (recording of side effects or adverse events) is measured using a structured interview once a week during the 4 weeks. Patients and supervisors are interviewed after the first, second, third and fourth week.
Secondary outcome measures
Acceptance is measured using the visual analogue scale at the end of the treatment period (after 4 weeks)
Motor function is measured using Wolf Motor Function Test at baseline and after 4 weeks of additional therapy.
