3. Activities For Manual Dexterity

Manual dexterity is the ability of the hands and fingers to make coordinated movements. Strong fine motor skills, such as used with writing, knitting, sewing, and other activities that involve the hands and fingers, rely on this dexterity. In young children, it is developed normally through routine activities that also require hand-eye coordination.

SSR 96-9p provides that most unskilled sedentary jobs require good use of both hands and the fingers; i.e., bilateral manual dexterity. Fine movements of small objects require use of the fingers, e.g., to pick or pinch. 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 involve small, meticulous actions with your hands, such as sewing, painting and playing a musical instrument.

Some children’s manual dexterity develops faster and stronger than that of others. A child with weak final motor skills may struggle some when learning to form letters and beginning to write. Because there are many reasons why fine motor skills may be affected and weaknesses in these areas may cause problems for children in school, pediatric occupational therapists often work with a variety of children to improve these abilities.

There are several ways to help a child improve his or her manual dexterity through simple hands-on activities. For a child, exercising the fingers and hands can dramatically lead to dramatic improvement. Parents may want to try some of the following activities:

• Children can thread O-shaped cereal pieces onto a length of yarn. This activity requires fine motor skills and is repetitively exercising the same muscles, all while practicing hand-eye coordination.


• Wooden peg games or similar toys that require placing pegs into small holes can improve motor skills.


• Sewing with yarn and cardboard cutouts is another activity that can improve manual dexterity and builds on fine motor skills. Children simply feed the yarn back and forth through holes, which is again repeating the same skill over and over.


• For particularly young children who cannot play with small objects, a classic shape sorter toy is a great place to start. For older children, small, interlocking building blocks are great ways to play while improving this ability.

Where young children are concerned, the goal is to improve manual dexterity to build fine motor skills and hand-eye coordination. In older individuals suffering from the onset of arthritis, however, preserving these skills is the primary concern. Exercising the fingers and hands without overdoing it is key. People who have arthritis should avoid prolonged activities that cause pain in the joints of fingers and hands, and simply perform activities in shorter periods. When possible, they should use both hands to reduce the strain and be sure to rest the joints before pain sets in.

Arthritis sufferers may want to consider periodic and passive hand massages, getting them either from a manicurist, physical therapist, or family member. Sometimes, working through the pain to keep the fingers limber is necessary, but people should not let the pain get ahead of them or their pain reliever. If painful arthritis has set in, patients should consult a medical professional for management and treatment. He or she can recommend hand exercises tailored to the individual.

Early arthritis detection and pain management along with a commitment to continue using fingers and hands is necessary to preserve manual dexterity, which will mean the person can retain most normal use of his or her hands for a long time.

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.
