Why MOTIMOVE?

MOTIMOVE is a multi-channel electronic stimulator which communicates via Bluetooth with a remote computer (graphical command display) for the selection of the application, fast one-time calibration, and setup of stimulation parameters, as well as the use of sensor driven control. After setup, MOTIMOVE can operate independently without the remote computer.

The physical functions that MOTIMOVE supports are: pedalling – biking, rowing, standing & walking, upper extremities movements, exercising to prevent disuse atrophy and contribution to maintaining range of movement of joints.

Special offer

MOTIMOVE is a multi-channel electronic stimulator which communicates via Bluetooth with a remote computer (graphical command display) for the selection of the application, fast one-time calibration, and setup of stimulation parameters. MOTIMOVE takes advantage of many sensors’ inputs for personalized sensor-driven control. After setup, MOTIMOVE can operate independently without the remote computer

The envisioned applications of the MOTIMOVE are:

  • The assistance of the volitional exercise of cyclic and goal-oriented functional movements;
  • Generation of missing movement that is the prerequisite for cyclic or goal-oriented functional movements;
  • exercise aiming to increase muscle strength and bulk;
  • an exercise that can decrease the level of spasticity;
  • an exercise that can increase the range of motion;
  • an exercise that prevents complications of no-use pattern;
  • an exercise that prevents pressure sores;
  • exercise increasing the local and overall blood circulation;
  • an exercise required to allow the standing (loading of the skeleton and bodily liquids by gravity)

MOTIMOVE APPLICATIONS

Choose one of our FES or create you own
that most suits you

Special offer

FES cycling

Lower extremity and abdominal muscles are activated in a sequence. The sequence is controlled by signals coming from the sensor measuring the angle of the crank arm. Every channel can be combined with AFU to postpone muscle fatigue. Applicable for hemiplegics, paraplegics, tetraplegics and fitness.


FES rowing

The user controls the activation of flexor and extensor muscles by pressing the switch on the handle. Every channel can be combined with AFU to postpone muscle fatigue. Applicable for hemiplegics, paraplegics and fitness.

FES walking

Real-time control based on the signals from the wired insoles (sold separately). Each insole comprises five high-quality industrial pressure sensors and a gyroscope measuring foot rate of rotation in sagittal plane. The sensors are hysteresis-free with no measurable time delay. The system allows precise detection of gait cycle events and pressure distribution over the sole. Values from 6 sensors and states of stimulation can be acquired to a remote computer with 100Hz via Bluetooth. Insoles are resizable.Applicable for hemiplegics or paraplegics with robotic aid.

FES grasping

Three-phase control of extensor and flexor muscle groups. Can be used for control of grasp (finger, wrist and thumb muscle) and prehension (shoulder and elbow muscles). Applicable for hemiplegics and tetraplegics.


FES exercise

Mild to strong stimulation for increasing the muscle bulk while in bed or a wheelchair. Applicable for ICU, prevention of pressure ulcers and fitness.

ANTI-FATIGUE UNIT (AFU)

AFU, or pulse splitter, is a device that distributes pulses asynchronously from one input to four outputs. Each pulse from the input is distributed to only one output in a shuffling manner.

Special offer

AFU is power supplied from the stimulator battery via audio cable, but it can also be supplied externally with coin batteries. It can be used with any other stimulator if the following limits are met:

  • pulse amplitude: 0-170mA,
  • pulse width (PW): 50-1000us,
  • frequency (F): 1-500Hz,
  • where PW * F ≤ 0.025.

AFU mimics the natural activation of a muscle to reduce FES-induced muscle fatigue. The asynchronous stimulation of different branches of a nerve innervating the same muscle or synergistic muscles via several electrodes at a lower frequency (≈10-15Hz) results with the fused contraction with the comparable force to the one generated with single large electrode activated at higher frequency (≈40–50 Hz); yet, postpones the muscle fatigue for several times. This phenomenon was confirmed in several clinical studies (see publications).

MORE CHANNELS

If you need more than 8 channels connect two MOTIMOVE-8 stimulators to control 16 channels at the same time.

Special offer

Two stimulators communicate in real-time via RS485 ports. Only one stimulator acts as a master that is receiving commands via Bluetooth, and other stimulator acts as a slave device, with Bluetooth automatically disabled.

SCIENCE MODE

MOTIMOVE stimulators can be used in science mode. The science mode means that each pulse can be controlled from an external device.

Special offer

Control is implemented via the RS485 communication protocol (Baud rate 115200). In this case, MOTIMOVE acts as a slave device with Bluetooth disabled.

The stimulator will respond to a set of commands sent in 40 bytes, as shown below:

  • 5 bytes 0xFF,0x00,0x25,0x00,0x00 (message start - 1 byte, message length - 2 bytes, 2 dummy bytes- 0x0A0B is for no delay between pulses on adjacent channels). All values after first 5 bytes are to be sent in a lower nibble
  • 3 bytes for the period in ms (defined by the master controller). Pulses on consecutive channels are delayed for T/8, where T is the period of stimulation.
  • 4 bytes for power modulation (max value 10 = 100%)
  • 4 bytes for pulse width (max value 1000µs)
  • 8 x 2 bytes - stimulation value per channel (max value 170mA)
  • 2 bytes for demultiplexer channel selection (0x0F,0x0F if demultiplexer is not used)
  • 4 bytes not used
  • 1 byte for turning on high voltage (0x01 - on, 0x00 - off, 0x02 – do not change)
  • 1 byte for checksum

EXTERNAL POWER SUPPLY

If you ever used a rechargeable battery-operated device you faced the empty battery shutoff. It takes “only” 3.5h to fully recharge the battery! We provide the External power supply; hence an immediate continuation of the use of MOTIMOVE is in your hands!

Special offer

MOTIMOVE is battery operated stimulator with an option to connect external supply in three ways:

  • external battery pack provided by 3F for prolonged outdoor use (Li-Ion 3500mAh)
  • accumulator with voltage in range 12-24V (if accumulator is used, the galvanic isolation must be implemented)
  • wall adapter with medical grade galvanic isolation for continuous operation indoor

ARDUINO MODULE

For those who want to develop their own firmware to control the stimulation patterns we provide an Arduino module to run our four independent high-power pulse generators.

Special offer

The module has 32-pin interface for external control with:

  • digital inputs for pulse duration (50-1000us),
  • SPI for pulse intensity 0-170mA in steps of 1mA,
  • Digital inputs for control of SSD relays for instantaneous, complete discharge of outputs, and
  • digital outputs for electrode detection.

Pulses can be generated at the same time on all channels (max 25µs delay between channels).
