We would like to share our clinical experience with a chronic SCI patient. The improvements we observed over therapy progression encouraged us to share this experience to support other clinicians working with the same patient group. In response to the therapy program the patient’s postural control improved in a significant way. Therefore, we would like to provide an overview about the therapy and the progression in this case study report.

Touch screen and acoustic feedback

Interactive interface (HD touch screen) providing visual and acoustic biofeedback by displaying information on trunk swing, weight-bearing distribution and seat and platform inclination.

hunova, huno and huno S, devices use gaming exercises to stimulate the patient to exceed previously achieved goals and scores, thus accelerating recovery and transforming therapeutic exercises into enjoyable activities.

The interface is mobile, allowing it to be used in both standing and sitting positions.

Tablet

The interface on the tablet computer allows clinicians to plan the session best suited to the patient, consult individual patient reports and produce diversified pathways from the comfort of their office. The tablet also allows the user to set up the patient’s planned rehabilitation session remotely.

Wireless position sensor

When placed on the subject’s trunk (or other area of the body, depending on the exercise), it monitors the movement of the subject, providing real-time acceleration and rotation measurements.

Standard ramp

The standard ramp is one of the extra optionals available for hunova, huno and huno S devices and is useful when the robotic system is used to transport non-self-sufficient and wheelchair-bound patients. The ramp can be removed and stowed away when not in use. Total length of ramp + hunova: 266 cm (104.7 inches).

Fixed ramp

The fixed ramp is one of the extra optionals available for hunova, huno and huno S devices and is useful when the robotic system is used to transport non-self-sufficient and wheelchair-bound patients. The ramp can be positioned either in line with hunova/huno/huno S (180°) or perpendicular to the device (90°), depending on the space available. Length of the ramp: 163.5 cm (64.3 inches).

Sensorized robotic platform

The robotic platform allows exercises to be performed in both bipodalic and monopodalic modality. Partial weight-bearing exercises can be carried out using the monopodalic mode. It can be used for passive therapy (mobilization), active therapy (with elastic or fluid resistance), proprioceptive therapy and assistive therapy (intervening to complete the exercise when the patient requires assistance). hunva and huno S seats are equipped with a force and torque sensor and an offset sensor.

Monopodalic configuration

Bipodalic configuration

Ankle sandal

Fits on the one-foot platform for ankle mobilization.

Knee and ankle stabilizer

When used in combination with the sandal, it prevents knee instability during ankle rehabilitation exercises.

Sensorized robotic seat

Induces both unidirectional and multidirectional movement with trajectories, speeds and ranges that can be set by the clinician. It can be used for passive therapy (mobilization), active therapy (with elastic or fluid resistance), proprioceptive therapy and assistive therapy (intervening to complete the exercise when the patient requires assistance). hunova and huno S seats are equipped with a force and torque sensor and an offset sensor.

Adjustable seat

The seat adjusts to each patient’s position to ensure maximum comfort and correct performance of the exercises. hunova, huno and huno S all allow the user to memorize the seat position for each patient, so that the same optimal configuration is always available.

Two removable handrails

Can be selected to suit the exercise (in sitting or standing positions) to ensure safe support for the patient.
