Is there any case law where a malevolent touch by a prison guard is actionable as an Eighth Amendment violation?

always violate contemporary standards of decency, not every "malevolent touch" by a prison guard is actionable as an Eighth Amendment violation. Id. at 9. "The Eighth Amendment's prohibition of cruel and unusual punishment necessarily excludes from constitutional recognition de minimis uses of physical force, provided that the use of force is not of a sort repugnant to the conscience of mankind." Id. at 9-10 (internal quotation marks and citations omitted). The following factors are relevant to a determination of whether a use of force violated the Eighth Amendment: (1) the need for the use of force; (2) the relationship between the need for force and the amount used; (3) the extent of injury inflicted; (4) the extent of the threat the officers reasonably perceived the plaintiff to pose to staff and inmate safety; and (5) any efforts made to temper the severity of the forceful response. Whitley v. Albers, 475 U.S. 312, 321 (1986).
