Medical Device development

With the collaborative development of the devices elaborated below, IIT and INAIL consolidate their commitment to solving issues relating to physical disability ,es, and to make available technologically advanced products at a competitive cost, which can be borne sustainably by the National nealthcare service and patients.

Orthotics Devices

The orthotic devices developed in Rehab Technologies are basically wearable robots that, using engines, are capable of providing assistance or resistance to movement to the various joints of the human body. In Some applications, such as on paralyzed limbs, they are used to provide the necessary strength to move the limb. However, the same hardware can be used, through appropriate control, even in assistive or restive mode for rehabilitation applications.

TWIN, The exoskeleton for the lower limb

This exoskeleton has the objective of becoming a personal device that allows spinal patients to walk autonomously, through a design approach that emphasizes ease of use, wear-ability, and transportability of the exoskeleton.
The device currently under development intends to benefit paraplegic patients, however, adaptations are being made to the machine that will also allow its use in -the rehabilitation of neurological disorders.

Exoskeleton for the rehabilitation of the shoulder and upper extremity

The post-injury and post-surgical trauma of the shoulder represent on average about 20% of  all physical disabilities treated at the largest Italian centre’s of rehabilitation. Mainly, these are injuries of the rotator cuff.

The recovery pathway, which requires a considerable commitment of time by a physiotherapist devoted to each and every single individual patient, can be slowed down or hindered by persistence of pain, joint stiffness and low patient stamina.

For this reason, a robotic device for the upper extremities and in particular for the shoulder is currently being developed, in order to improve the efficacy and efficiency of the rehabilitation process for this particular area of the body,.

The  current device under-development can also be used on other types of patients, such as those with a neurological disorder, through a future integration of appropriate control capabilities.


The definition of  a prosthesis includes any  auxiliary aid or device that replaces a missing part of the human-body. In Rehab Technologies, high-tech upper and lower limb prostheses  are currently in development,, integrating  advanced mechatronics in order to realistically emulate the biomechanical behavior of human limbs.

HANNES, The polyarticulated hand

The hand prosthesis HANNES aims to bridge the gap, on the one hand between complex poly-articulated and multifunctional prostheses, which are capable of very high performance, but which are very expensive and contain very delicate and complex mechanisms, and on the other hand, tri-digital prostheses, which are characterized by low cost, robustness and ease-of-use, but offering limited versatility and poor aesthetics.

Hannes aims to be easy to use, robust, low-cost and simple but with a the versatility of grip and aesthetic appearance comparable to that of the human hand. This device derives it’s technology from a collaboration between Pisa and the IIT SoftHand project, which was initially developed for humanoid robots and for prosthetic devices, within of the European projects SoftHands and SoftPro, coordinated by IIT.

In addition a project is also underway that involves integrating the hand prosthesis HANNES into a complete upper-extremity prosthetic system.

Lower limb prosthesis

The near-total majority of lower-limb devices fitted to patients to date are either passive, or  do not fully consider or regulate themselves depending on patient’s type of walk., therefore entirely depending on the remaining muscles of the patient and on the interaction of the prosthesis with the external environment, which often results inefficient and unnatural walking style. However, these problems can be balanced by the use of active electromechanical prosthetics, but at much higher cost than their passive counter-parts.

The lower limb prosthesis system currently under development, has the prerogative of being a high-tech device, which can nevertheless  “bridge the gap” between simple passive devices and very advanced and effective, yet very expensive prostheses currently available on the market.


Rehabilitation devices have the objective of allowing a person to recover compromised functionality as a result of an injury, neurological-trauma, or age.

Hunova, The rehabilitation platform

The current rehabilitation processesused in the orthopedic and neurological fields,  often utilise a series of simple tools and devices. These, besides requiring a considerable organisational and physical commitment to the operators of the sector, do not guarantee the repeatability of the exercises, and do not guarantee any measurable or objective improvement for the patient.
To meet the needs of patients and therapists alike, Hunova was developed, the first commercial product developed by the Rehab Technologies IIT – INAIL Lab.

Hunova has now been commercialized by a spin-off of IIT,  Movendo Technology, and is already installed in numerous hospitals and rehabilitation centers in Italy and abroad.
