Gloreha is an Italian medical technology company headquartered in Milan, Italy, specializing in the development and manufacture of robotic rehabilitation systems specifically for hand and upper limb therapy. Founded in 2008 as a spin-off from Scuola Superiore Sant'Anna (Pisa, Italy) — one of Europe's leading robotics research institutions — Gloreha focuses exclusively on hand rehabilitation, distinguishing it from competitors with broader rehabilitation portfolios.
The company's core innovation is a cable-driven robotic architecture that provides gentle, compliant assistance for hand movement — particularly suited for patients with limited strength or severe motor impairment. Gloreha's systems are used in rehabilitation hospitals, outpatient clinics, and research institutions across Europe, North America, and Asia for the treatment of hand dysfunction resulting from stroke, Parkinson's disease, multiple sclerosis, spinal cord injury, and other neurological conditions.
Gloreha was founded by engineers and clinicians from the BioRobotics Institute at Scuola Superiore Sant'Anna, a world-leading robotics research center in Pisa, Italy. The founding team recognized that hand function — critical for independence in activities of daily living — was underserved by rehabilitation technology. While robots for gait training and arm therapy were well-established, hand rehabilitation lacked dedicated solutions capable of addressing the complex, multi-joint movements of the fingers and wrist.
The founding technology was based on cable-driven actuation — a design that uses cables (like tendons) to move the fingers, producing natural, biomimetic movement with inherent compliance. This approach differs from gear-and-linkage robots (like Hocoma's AMADEO) and was particularly suited to patients with very weak muscles who could not tolerate rigid robotic assistance.

- Significant improvements in:
- Finger range of motion (23% increase)
- Grip strength (18% increase)
- 9-Hole Peg Test time (15% improvement)
- UPDRS upper extremity scores
- Authors concluded cable-driven rehabilitation effectively addresses PD hand dysfunction
Sardina et al. (2020):
- Multi-site study of Gloreha in chronic stroke patients (n=45)

¶ Hand Rigidity
Parkinson's disease produces marked rigidity in the hand and fingers, characterized by:
- Increased muscle tone (cogwheel or lead-pipe rigidity)
- Reduced range of motion
- Difficulty initiating movement (bradykinesia)
- Micrographia (small, cramped handwriting)
The Gloreha system addresses these through:
Passive Mobilization: The robot continuously moves the fingers through their full range of motion, counteracting the progressive joint stiffness that develops in PD. The cable-driven design provides smooth, gentle movement that does not trigger defensive muscle contractions.
Tremor Damping: The system can provide gentle resistance to Parkinsonian tremor, allowing patients to practice fine motor control in a controlled environment.
Bradykinesia Training: Active-assisted modes require the patient to initiate movement, with the robot providing support to complete the motion. This "forcing" of movement may help counteract the slowness that characterizes PD.
PD commonly impairs fine motor skills, affecting:
- Buttoning clothes
- Writing
- Using utensils
- Manipulating small objects
The Gloreha provides targeted training for these skills:
Grip Training: Practice opening and closing the hand with functional objects
Dexterity Exercises: Fine finger movements for coordination
Functional Tasks: Real-world practice integrated into therapy games
Hand rehabilitation may provide benefits beyond motor function:
- Cognitive Engagement: Challenging hand exercises require attention and concentration
- Sensory Input: Touch and movement provide sensory stimulation
- Mood Effects: Successful therapy may reduce apathy and depression
- Social Participation: Improved hand function enables return to valued activities
Gloreha's proprietary cable-driven design represents a fundamental departure from conventional robotic systems:
How It Works:
- Cables are anchored at the device base and routed through guides along the finger
- Actuators pull cables to flex fingers; releasing cables allows extension
- This mirrors the body's own tendon-driven architecture
- Built-in compliance: cables stretch slightly, preventing jarring movements
Advantages Over Gear Systems:
- Inherent Compliance: Natural give prevents injury and feels more comfortable
- Lightweight: Fewer mechanical components = lighter weight on patient hand
- Biomimetic Movement: Mimics natural finger kinematics
- Patient Tolerance: Better accepted by patients with severe weakness
Gloreha systems incorporate multiple sensor modalities:
- Force Sensors: Measure interaction forces between patient and robot
- Position Encoders: Track finger position at each joint
- Surface EMG (Optional): Detect residual muscle activity for myoelectric control
- Touch Sensors: Object detection for functional training
Gloreha Therapy Manager:
