A grasp is an act of taking, holding or seizing firmly with (or as if with) the hand. An example of a grasp is the handshake, wherein two people grasp one of each other's like hands.
In zoology particularly, prehensility is the quality of an appendage or organ that has adapted for grasping or holding.
Development
The development of grasping is an important component of child development stages, wherein the main types of grasps are:
- Raking grasp, wherein the fingers, but not including the thumb, do all the holding.[1]
- Palmar grasp, wherein the fingers squeeze against the palm, instead of against themselves as in the raking grasp.[1] Children are usually able to use a palmar grasp by the age of 6 months.[2][3]
- Pincer grasp or whole-hand grasp, wherein both palm and the fingers, including the thumb, are involved in holding objects.[1] Children are usually able to use a pincer grasp by the age of 9 to 10 months.[2][3]
Reflex
The palmar grasp reflex (sometimes simply called grasp reflex) is among the primitive reflexes and appears at birth and persists until five or six months of age.[4] When an object is placed in the infant's hand and strokes their palm, the fingers will close and they will grasp it. The grip is strong but unpredictable; though it may be able to support the child's weight, they may also release their grip suddenly and without warning. The reverse motion can be induced by stroking the back or side of the hand.

- Popovic Maneski L, Kostic M, Bijelic G, Keller T, Mitrovic S, Konstantinovic L, Popovic DB.AbstractWe designed a new surface multi-pad electrode for the electrical stimulation of the forearm that is effective in controlling functional grasp in hemiplegic patients. The electrode shape and size were designed on the basis of the surface stimulation map of the forearm, determined from measurements in seven hemiplegic patients who had limited or absent voluntary movements of the fingers, thumb and wrist. The stimulation map for each patient was assessed with a conventional set of single pad Pals Platinum electrodes. Since the sites for the stimulation varied greatly between patients, the end result was a rather large multi-pad electrode. Modulating multi-pad electrode size, shape, position and individual pad stimulation parameters allows us to accommodate the diversity of the neural tissues in patients that need to be activated for functional grasp. This also allows asynchronous activation of different portions of the muscle and dynamic adaptation of the stimulation sites to appropriate underlying tissues during functional use. The validity of the determined stimulation map was tested in the same group of hemiplegic patients. The selected set of active pads resulted in fully functional and reproducible palmar and lateral grasps similar to healthy-like grasps.
