Hi I have a question. Would a human being be able to move his body voluntarily without help from artificial nerve stimulation and most importantly without any signals from the afferent nerves reaching the brain or spinal cord(the nerves that supply sensory input)?

What do you mean by artificial nerve stimulation? What kind of movement do you mean? Is all sensory input non-funtional? If there is absolutely no sensory input muscles could contract, but there would be no way for them to contract as functional, purposeful movements.

Although muscle movement can be an efferent neural response to afferent neural stimuli, such movement may also be produced solely by brain function. For example involuntary movements or obsessive compulsive behaviors arising from iterative thoughts rather than afferent or neural stimuli external to our physical sensory systems.
