Finger Paralysis Rehabilitation

Background
Post-stroke patients often face challenges with hand mobility due to finger paralysis, spasticity, and weakened biosignals. These issues severely impact daily activities and the ability to regain independence. In response, a novel neurorehabilitation device has been developed to support and enhance finger mobility during therapy sessions. Housed in a cart, the system integrates a medical box PC and a medical monitor to perform biosignal analysis and control the device's motor-driven wire system.

The device aims to provide lightweight and effective support to the paralyzed fingers while incorporating cutting-edge technology to identify movement intent through weak biosignals. By employing advanced algorithms and compact, wearable components, this solution is positioned to revolutionize rehabilitation therapy for individuals suffering from finger paralysis. 


Pain Points
The need for esophageal temperature monitoring arises from several challenges faced by healthcare professionals:
• Strength Requirement for Spasticity Management
Patients with finger spasticity require significant force to open tightly clenched fingers. Traditional designs that place motors near the hand make the attachment bulky and heavy, while reducing weight often compromises power output.
• Weak Biosignals from Paralyzed Hands
Post-stroke patients typically generate weak biosignals that conventional systems struggle to detect and interpret. This limitation makes it difficult to accurately identify user intent, thereby reducing therapy effectiveness.
• Complexity of Finger Motion Detection
Conventional algorithms rely on myoelectric signal intensity to estimate motion, which is inadequate for detecting complex finger movements. The intricate interplay of multiple muscles in finger motion requires a more sophisticated approach.
• Cumbersome Therapy Devices
Many existing rehabilitation devices are not user-friendly during occupational therapy. They restrict natural hand movements, making it difficult for patients to perform meaningful exercises that simulate daily life activities.




Wincomm Solutions

Featuring on efficient computing performance, high integration, uniform interface design, and medical grade certification.

The integration of a medical box PC, WPC series and medical monitor, WMD series, enables this innovative rehabilitation device to address the above challenges effectively:
1. Compact and Powerful Wire-Driven Hand Unit
By using a wire drive system connected to a motor housed in the cart, the device offers strong pulling force to open spastic fingers. This design ensures the hand unit remains lightweight and compact while providing precise, powerful assistance for each finger.
2. Biosignal Amplification and Intent Detection
The medical box PC processes weak biosignals using advanced signal amplification technology and proprietary algorithms. This allows the system to identify the user’s intent to move even with minimal surface myoelectric activity, making rehabilitation accessible to patients with severe paralysis.
3. Advanced Motion Identification Algorithms
The system leverages waveform analysis instead of intensity-based estimation to decode complex finger motions. This approach enables the device to distinguish subtle finger movements, supporting activities like grasping and manipulating objects.
4. Wearable and User-Friendly Design
The robotized parts are worn on the back of the hand, leaving the palm free for grasping and releasing objects. The device’s independent control of all five fingers allows patients to engage in occupational therapy tasks that mimic real-life activities, improving their functional recovery.
