Manual dexterity is defined as a person’s ability to make precise, small, or intricate movements with their hands and fingers. It is our body’s unique capability to grasp and manipulate objects with total control but also to do so without thinking about it. Most of us do not realize just how important manual dexterity is in our day-to-day lives until it is gone.
As we age, manual dexterity will begin to decrease naturally. Muscles and neurological functions that once perfectly controlled our hand motions slow down and become sluggish. In other instances, an injury can cause a sudden and sharp decrease in manual dexterity.
Manual dexterity involves the development of hand-eye coordination and very fine motor control. Imagine the level of care and precision required in certain activities, hobbies and professions that.
Without manual dexterity, some of the commonplace practices that become difficult or painful include:
- Fine motor skill (or dexterity) is the coordination of small muscles, in movements—usually involving the synchronisation of hands and fingers—with the eyes.The complex levels of manual dexterity that humans exhibit can be attributed to and demonstrated in tasks controlled by the nervous system.Fine motor skills aid in the growth of intelligence and develop continuously throughout the.

As it can be seen, the loss of manual dexterity is troubling. Many people find that they struggle in their everyday life as the precise control of their hands becomes limited. It may even become impossible to continue regular work functions, threatening their jobs and wellbeing.
Comfortable Therapy Can Help Restore Dexterity
Manual Dexterity Activities For Kids
People seeking to restore their manual dexterity can come across all types of apparent solutions. Many promise a quick fix through surgery but do not mention the inherent dangers with this process. Some suggest taking medications to ease the pain of arthritis, but also rarely consider the potential side effects of using manufactured substances regularly.
For a solution with virtually no chance of adverse side effects that also steadily and comfortably returns manual dexterity, occupational therapy should be a first choice. Occupational therapy is physical therapy directed towards specific body parts to enable specific functions. For example, if someone needs to type for long hours at a time but has lost the ability to do so without pain, occupational therapy could include exercises that mimic typing or focus on finger joints.
At King Street Rehab, our Westchester County rehab center specialists can help you plan an occupational therapy session schedule that works best for you. Our goal is providing you the opportunity to restore your manual dexterity in total comfort. Give us a call at (914) 600-7149 or schedule a tour of our luxurious facility today to learn more.
Dexterity is motor wisdom: the organization and application of a lifetime of experience in movement. It is the highest achievement of the motor system, and it consists in the judicious use of strength, coordination, sensation, and attention to execute demanding motor tasks. Naturally, dexterity is also highly susceptible to systemic disturbances. We all fumble with our keys in cold weather. Manual dexterity is severely hampered in Parkinson’s disease, stroke, and MS, and it also declines with healthy aging starting at age 60 years. This disruption profoundly impacts our ability to perform activities of daily living and it limits our professional lives.
Despite its importance, fundamental understanding of dexterity is lacking. The present work combines ideas from dynamical systems theory, screw theory, impedance control, and the theory of synergies to uncover the control processes that facilitate dexterous switching between tasks under uncertain conditions. We are currently focusing on prehensile behavior and studying tasks that demand a compromise between two contrasting attributes of motor action: stability (e.g., holding a tray of wine glasses) and flexibility (e.g., navigating a crowded dance floor with the tray). We analyze fingertip forces and movement kinematics to test hypotheses regarding action stability for dexterous prehensile tasks.

Current project
We are exploring stability modulation in manual force production tasks in response to the degree of expectation of impending movement. Participants produce fingertip forces that are measured by force sensors. They modulate their force and follow a moving force target displayed on the computer screen.
Typical participant response
We estimate the stability of the current manual state by analyzing the structure of variability in the finger forces (via the uncontrolled manifold method). Participants lower the stability of their current state when they expect to move in the future. They remain in this state of lowered stability for at least 2-3 seconds. We argue that lowering stability facilitates future movements. However, it also makes the current state susceptible to external disturbances. This strategy may prove counter-productive in risky situations (grasping containers with hot liquids, or other behaviors like upright posture).
We have extended these ideas to prehension. We have observed that the coordination between the digit forces (quantified using recurrence quantification analysis) is altered when participants expect to change the motion of a hand-held object.
