Mobilexo Arm Host Controller:  Multi-integrates Electromyography (EMG) control, Neuromuscular Electrical Stimulation (NMES), Soft robot;

After a stroke, damage to the patient's brain may result in the failure of motor control signals to transmit correctly to the muscles. 

In such cases, what are the potential advantages of utilizing electromyography (EMG) signals from the affected side?

EMG records the electrical activity generated by muscle contractions. Even if a patient's motor function is impaired due to a stroke, the residual muscle activity, albeit weak, can still reflect their intention to perform movements. When a patient attempts to actively contract their muscles, robotic assistance can enhance the connection between movement intention and actual action, thereby aiding in the rebuilding of neural pathways. The integration of "attempted movement" and robotic-assisted movement can fortify the "movement intention → action execution → sensory feedback" closed-loop circuit, promoting cortical reorganization, particularly the activation of the primary motor cortex (M1) and the sensorimotor cortex.

Although electroencephalography (EEG) signals originate directly from the motor cortex of the brain, they exhibit low signal-to-noise ratios and are susceptible to interference from other brain areas and activities, such as attention fluctuations. Moreover, patients require strong cognitive abilities to produce specific EEG patterns or engage in motor imagery. Stroke patients may experience cognitive impairments or brain damage that hinder their ability to generate effective EEG signals, and discrepancies between motor imagery and actual movement may render EEG control less reliable than EMG. 

In the biofeedback perspective, EMG provides more direct feedback, allowing patients to immediately observe or sense their muscle activity, which assists them in adjusting their efforts and enhancing training effectiveness. In contrast, EEG feedback tends to be more abstract and indirect, making it challenging for patients to directly associate with specific muscle movements, leading to suboptimal learning outcomes.

When patients endeavor to generate muscle contractions, even if weak, EMG can trigger robotic assistance, synchronizing movement execution and sensory feedback, thereby promoting the reorganization of damaged motor circuits. EEG, in contrast, may primarily involve movement intention, lacking synchronized feedback with actual action execution, rendering it less effective than EMG.

How It Works?

A novel multi-integrated robotic system that incorporates soft exoskeleton and neuromuscular electrical stimulation in one system for effective and self-help mobile rehabilitation after stroke. It can assist the elbow, wrist, and fingers to perform sequential arm reaching and withdrawing tasks under voluntary effort control through electromyography signals from the paretic limb, with a lightweight, compact, and low-power requirement design.

Frequently Asked Questions

Mobilexo Arm is a hand rehabilitation device, which allows neurologically affected patients to conduct high repetition hand rehabilitation training at the comfort of their homes. In a rehabilitation centre, Mobilexo Arm assists therapists in their normal activities, capable of intensifying rehabilitative treatment on the patient and offering a longer period of training with minimal supervision. The software offers multiple exercises, which allows the therapists to conduct personalized therapy based on the patient’s clinical requirements.

Mobilexo Arm allows passive mobilization exercises and active-assisted exercises, accompanied by functional tasks training.

Key Features:

  • Continuous Passive Motion: Passively mobilizes the distal interphalangeal, proximal interphalangeal, and metacarpophalangeal joints of the hand without active movements by patients. Supports early hand mobilization in the acute phase.
  • Functional Task Training: Trains patient in performing critical functional tasks in daily living, such as gripping and tripod-pinching, while interacting with real objects.
  • Intention Detection: Detects the residual movements of the patients and assists if necessary.

The set up of Mobilexo Arm is straightforward, users will be provided with a set of user manual for reference. It is followed by a training session on the set up of Mobilexo Arm for daily usage for the patient’s caregiver. The average time taken to set up the system is less than 5 minutes.

The effect of Mobilexo Arm varies from person to person, as it is an automated device that helps in hand rehabilitation in high repetition. It also requires the patient to remain focused and motivated throughout the rehabilitation session, which is crucial in the relearning and retraining of hand motor movements, as well as in stimulating neuroplasticity. We have seen patients with improved grip strength and reduced spasticity after months of Mobilexo Arm training.

The current Mobilexo Arm system consists of 16 passive and 17 active training exercises. The passive training mode, including continuous passive motion training, enables early-mobilization in the acute phase, while the active training mode strengthens communication between the brain and body and stimulates neuroplasticity. Additionally, the Mobilexo Arm Pro offers functional task training, which allows users to train not only their hands but also their entire upper limb through action observation therapy. Bilateral training allows patients to practice mirror therapy and motor imagery, enhancing patients’ abilities in action planning and motor execution.

The recommended frequency to use Mobilexo Arm is at least one hour per day, and to use it daily.

In Hong Kong, The Con Technology have extended a clinical arm – Hong Kong PolyU Jockey Club rehabilitation Centre. You will be assessed by a professional therapist who provides advice on how Mobilexo Arm  can help you in your recovery journey, either through the centre’s personalized treatment programme or home rental programme. Please contact us or go to the Hong Kong PolyU Jockey Club rehabilitation Centre website to book an appointment!
