Electronic Knee

Persons whose limb has been either severely damaged via trauma, disease, or

congenital defect are required to undergo transfemoral amputation, a surgical

procedure performed to remove the lower limb at or above the knee joint. In order

to aid transfemoral amputees involved in activities requiring a high level of

stance stability our manufacturer has developed an intelligent prosthetic device

known as Electronic Knee. For adaptive gait, the knee adapts to patient

movement style in real time with the integration of indigenously developed

electro-goniometer, force resistive sensor and accelerometer in order to control

the swing phase dynamically. The Electronic Knee consists of sensor like electro-

goniometer and force resistive sensor and accelerometer as sensor mechanisms.

Knee is based on controlling a swing phase using a pneumatic cylinder

mechanism attached with the embedded control mechanism to its control its flow

control valve. The required energy to extend the knee into new gait cycle is

provided by a spring mechanism. Three variants (electronic sensor, remote and

mechanical) of knee have been developed.

Features:

Mechanical with valve control.

Electronic knee joint with remote control.

Electronic knee joint with three sensors (electrogoniometer, force

sensitive resistor and accelerometer).

Above Elbow Myo-electric Arm

Military personnel and factory workers who often lose their upper limb partial or

full find it very difficult to perform various operations that a normal arm does.

Although different solutions are available but most are non-functional cosmetics.

Due to financial constraints imported functional solutions are beyond scone for

an Indian individual. Based on the location of amputation, our manufacturers

developed two solutions namely below elbow and above elbow myoelectric arms.

Below elbow myoelectric arm technology is an indigenous myoelectric arm

consists of two parts - mechanical assembly and electronic circuitry. Mechanical

part comprises gripping fingers, palm, wrist and lower portion of upper limb.

Electronics involve myoelectric electrodes, circuitry to process the myoelectric

signal and a dc motor for opening and closing the hand with proportional grip

force control. A body coloured glove provides the cosmetic appeal to the entire

setup.

Above elbow myoelectric arm consist of gripping fingers, palm, wrist and elbow

joint of upper limb. This arm further has two DC motor one for hand movement,

another for the movement of the elbow joint. EMG sensors are there to pick up

myoelectric signals from the stump and there is circuitry to process and

12

condition the signals to perform the opening and closing of hand and micro-

switch/wireless switch for elbow flexor and extension.

Virtual Intelligent Techniques for Rehabilitation

of Persons with Motor Disability (VIBHRA)

Patients with spinal cord injury often experience permanent loss of

strength, sensation and function below the site of the injury. Rehabilitation

and assistive devices allow many people with spinal cord injuries to lead

productive, independent lives. Treatments include drugs to reduce

symptoms and surgery to stabilize the spine. Our manufacturer developed

Virtual Intelligent Techniques for Rehabilitation of Persons with Motor

Disability (VIBHRA) a virtual intelligent platform for motor rehabilitation of

persons with disabilities.

It combines experience from virtual reality and knowledge from machine

intelligence to enhance neural reorganization that optimizes the physical

rehabilitation outcomes in individuals with disability. It provides

stimulating sensory feedback to promote motor learning and encompasses

tools that help to understand the biology of disability. The system

integrates inexpensive devices like Microsoft Kinect and Wii Balance Board

to improve balance and neuromuscular functions. Quantification of motor

disability is done through presenting the individuals with situations/tasks

that require use of groups of muscles and body parts like an augmented

rehabilitation measure such as virtual function reach test.

Returns/Benefits

Real-time visual feedback of the executed movements allows the

persons with disabilities to perceive a picture of patient’s movement

16

projected on the screen in real-time and correct compensatory

postural adjustment and movement learning.

Visual response combined with verbal instructions by the system

(zero physiotherapist assistance), can ease the learning of body

postures with better biomechanical arrangement while executing the

tasks and activities.

Therapy system provides intense, continuous and repetitive training

to the individuals with disability, simultaneously bringing maximum

engagement through fun, animated virtual environments.

The system incorporates a novel virtual functional reach test,

modified functional reach test and other clinical measures that

makes daily quantification of improvement lot easier.

Myometer

Our manufacturer developed a portable, hand held instrument that is used to find

out the optimum location to require the signal generated by muscle activity. The

acquired EMG signal from the surface of the residual limb is amplified and

displayed in the form of bar graph. The level of the bar graph is proportional to

the level of EMG signal available at the skin surface. The instrument is useful for

the physician to analyze the muscle activity. It can also be used to train the

patient to find the best location of EMG electrodes without using the actual

prosthesis.

Features

The device has option to show the either RMS or DC correspondence to RMS

value of EMG of two channels on the screen or all these values together on the

same screen.
