Despite aesthetics being a significant factor, the primary purpose of a prosthetic device is to regain lost hand function. Prosthetic devices play a significant role in compensating for the loss of fine, coordinated movements of the hand. They provide tactile sensation and proprioceptive feedback, enabling you to complete tasks more efficiently. How do they accomplish this feat? Let’s explore the details.

Restoring length and dexterity and enhancing grip and manual dexterity are key to improving overall hand function. Prosthetic devices strive to achieve:

  • dexterous motor function comparable to that of the human hand
  • extending the affected arm or hand
  • offering fully articulating body-driven prostheses that restore length and enhance dexterity
  • regulating the force and position of the prosthetic fingers, allowing for a range of grips that enable you to perform various tasks.

Importance of Restoring Length and Dexterity

To regain your hand’s functionality, restoration of length and dexterity is indispensable. The finger length, particularly the fingernails, has a positive influence on hand dexterity. A fingernail length of 2 mm can enhance sensory perception and improve the ability to pick up small objects with precision. Prosthetic fingers replicate the natural length and dexterity of real fingers, contributing to more controlled and precise movements.

This restoration of length and dexterity enhances pinch grip strength, fine motor skills, and overall grasp in the middle and distal phalanges. It enables you to perform various tasks that demand precise movements and grip, supporting your independence and enhancing your quality of life. With the right prosthetic fingers, you can regain your hand’s functionality and return to your daily activities with ease.

Enhancing Grip and Manual Dexterity

Two key elements in hand function are grip and manual dexterity. Prosthetic fingers improve grip by leveraging cutaneous sensory cues and muscle activation to adjust force while handling objects. They employ a sensorimotor control system that regulates the force and position of the prosthetic fingers, allowing for a range of grips.

These grips encompass:

  • Opposed grip
  • Glove grip
  • Tripod grip
  • Trigger grip
  • Precision grip (open & close)
  • Rock grip
  • Power grip
  • Tool grip
  • Fine pinch closed
  • Fine pinch open
  • Lateral pinch
  • Chuck grip

With these features, prosthetic fingers can greatly enhance your hand’s functionality and make everyday tasks easier.

Personalizing Your Prosthesis: A Tailored Approach

Personalization plays a crucial role in prosthetics. Rather than a one-size-fits-all approach, a tailored prosthetic device can offer a more comfortable fit and better results. Whether it’s matching your skin tone or achieving natural movement, personalization can make a big difference in how well you adapt to your new prosthetic finger.

It is vital to guarantee a natural and seamless appearance that harmonizes with your natural skin color. This involves a multi-layered moulding technique that incorporates intrinsic and extrinsic coloration processes to replicate the natural layered anatomy and optical properties of human skin. But what about movement? Can prosthetics mimic the natural movements of a real finger?

Matching Your Skin Tone

Matching your skin tone is an important step in personalizing your prosthesis. It ensures a natural and seamless appearance, which can have aesthetic and psychological benefits. Technologies such as the Spectromatch e-Skin spectrocolorimeter utilize spectral data to enable fast and precise color matching, resulting in a prosthetic that blends seamlessly with your skin.

But this seamless look isn’t permanent. Over time, your skin tone might change due to factors like sunlight exposure or age. To maintain a natural look, prosthetic companies occasionally remake the prosthesis or externally adjust the color to match your current skin tone. This way, your prosthetic finger can continue to look natural and lifelike.

Achieving Natural Movement

It’s a complex task to achieve natural movement in a prosthetic finger. It involves replicating the intricate movements of natural finger joints, considering dexterous and natural finger movements, and emulating natural hand closure. Various technologies, including joint-driven, cable-controlled, and wrist-driven mechanisms, are integrated into finger prosthetics to achieve this.

The results are promising. Prosthetic fingers enable some degree of movement, enhancing your dexterity and ability to manipulate objects. They offer pressure stimulation and clear feedback during touch, contributing to more controlled and precise movements.

With recent technological advancements, even bionic hands and bioinspired robotic fingers are now possible, offering agile, lightweight, and robust movement.
