KNEE INDEX

For functional knee assessment and treatment

The first functional knee assessment index

The knee index is an assessment index developed for individuals with a knee condition or who undergo knee surgery.

It allows therapists to plan optimum individualized rehabilitation with a pathway developed to suit the patient’s needs.
Patient assessment using the knee index is based on tests that determine:

  • The active and passive range of motion of the knee
  • The post-surgical proprioceptive deficits of the limb
  • Weight-bearing distribution
  • Lower limb strength
  • Motor control
  • Posture
  • Patient’s progress during the rehabilitation process
  • Recovery of full function by comparing the test indicators of the operated limb with those of the healthy limb

Multi-sensors

Our “Multi-sensors” solution, developed for use with hunova, huno and huno S devices, exploits the inertial sensor technology incorporated into all hunova, huno and huno S applications and extends its use to 3 sensors, thus expanding the Movendo assessment range.

The Multi-sensors solution allows clinicians to measure the range of motion of the knee joint, an essential parameter to be monitored during recovery from an injury or surgery.

The measurement data is stored and used to generate a dedicated report, comparing the ranges of motion of the patient’s knee on all planes.

Incorporating this measurement into the knee index assessment package enhances the analysis and enables therapists to obtain a comprehensive evaluation.

The knee index was developed to combine assessment and rehabilitation in a simple, automatic tool, to give therapists the possibility to fine-tune their patients’ recovery pathway in line with their impairments.

The index and results

The knee index generates a summary rate score reflecting the functional status of the knee before surgery and in the various phases of rehabilitation which is obtained by combining the results of assessments grouped into 7 areas.

If a deficit is detected in one or more functional areas, the knee index suggests a rehabilitation pathway focused on the recovery of these areas.

Training suggestions

The knee index covers several functional areas and gives an indication of which of them have functional limitations. Based on the assessment, the algorithm suggests a targeted rehabilitation program with customized exercises.

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.

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.
