Technical Data Sheet
The ArmeoSpring is a device intended for the rehabilitation of patients with mild to moderate impairments in upper limb function. The ArmeoSpring provides functional training to improve upper limb function. The ArmeoSpring consists of a passive instrumented arm orthosis with an adjustable spring mechanism, which supports the weight of a patient’s arm and measures patient’s movements during functional upper limb exercises. Weight bearing provided by the orthosis facilitates movement exercises presented on a computer screen via motivating game-like exercises with the aim to increase range of motion, strength, and movement coordination of the impaired arm.
Key Features
- Arm orthosis with integrated weight compensation mechanism
- 3D position detection of arm segments and grip strength sensing
- Game-like virtual reality and augmented performance exercises motivate patients to train actively
- Objectively track patients’ progress
- ManovoSpring hand orthosis with integrated hand opening support (optional module)
Adaptability to Patient
- Electric lifting column for comfortable height adjustment (range: 400 mm / 15.7 in.)
- Continuous adaptation to subject’s dimensions
- Forearm lengths (elbow to grip axis): 258 – 418 mm (10.2 – 16.5 in.)
- Upper arm lengths: 215 – 305 mm (8.5 – 12 in.)
- Continuous adaptation of weight compensation force to subject’s needs.
Example values in horizontal position and middle length settings are:- Forearm weight compensation: 0.7 – 2.4 kg (1.59 – 5.3 lb.)
- Upper arm weight compensation: 0.5 – 3.8 kg (1.1 – 8.4 lb.)
- Continuous adaptation of hand opening support (0.3 – 0.9 Nm) if ManovoSpring is connected
Armeocontrol Software
- User database with an individual account for every patient (allows for managing individual therapy schedule, storing patient settings, logging activity and results)
- Parameters individually adjustable to the patient’s needs and abilities:
- Exercise workspace
- Difficulty level of every exercise
- Visual detail
- Therapy time
- > 20 motivating exercises
- Assessments for relevant parameters of the patient’s performance (coordination, reaction time)
- Track patients’ progress:
- Summary of the patient’s progress
- Detailed, Excel readable exercise report
