A patient with C6 quadriplegia will have difficulty using which type of prehension?

In patients with C6 quadriplegia, the use of the hands is significantly impaired due to loss of control over specific muscle groups necessary for fine motor skills. The C6 level of injury indicates that the patient has some available wrist extension and limited hand function, often allowing for more gross movements rather than fine precision.

Among the types of prehension mentioned, "Three Point Palmar Prehension" involves using the thumb and two other fingers (usually the index and middle fingers) to grasp objects. This method requires intricate coordination and strength in finger flexion and opposition, which the patient may struggle to achieve due to muscle weakness and lack of fine control at the hand level.

In contrast, other types of prehension such as "Modified Pincer Grip," "Lateral Pinch," and "Power Grip" can be managed to a greater extent, as they rely on larger muscle groups and can often be accomplished through compensatory strategies utilizing the wrist or other parts of the hand. The Power Grip, for instance, uses the whole hand to enclose an object and does not require the same degree of precision that the Three Point Palmar Prehension mandates.

Thus, the patient's limitations in hand function make it particularly challenging to execute the
