Peripheral N. Performance S & M Physiologically • increase nerve threshold for depolarization • decrease nerve conduction • block nerve conduction Fxnally increased pain tolerance • & Longer application = greater conductivity loss • affects performance negatively - Muscle performance • decreased BF • decreased motor n conduction • decreased sensory n conduction • MAYBE jt awareness reduction - careful applying to superficial neural tissue • ulnar/radial n • posterior tibial n ~ & cryotherapy for 10 min or more to account for performance cools tissue for therapeutic & physiologic response - change in treated tissues - change in blood - change in sensory & motor n fxn - change in inflammatory processes • - always adjust interventions if using Summary • - cryotherapy found to be indicated for use in pt w/ acute musculoskeletal injuries 4.4 Modes and Assessment of Cryotherapy Modes • ice & gel packs • massage vapocoolant • • contrast baths • compression units Cold packs • crushed ice w/ water or wet towel • barrier b/w pack & skin • properly position for underlying condition • RICE - penetrates deeper than gel packs - just make sure part is exposed - rest, ice, compression, elevation - acute msk injury ice massage • smaller areas of skin • HEP/self management • trigger points • 5-10 min vapocoolant • combined w/ stretching for myofascial tension/ trigger points • repeated several times in one tx • no deep penetration contrast baths - common for energy transference • cryotherapy convection w/ water turbulence jets/pumps • ensures circumferential contact w/ cooling agent (submerged) • difficult to clean contraindication • circulatory insufficiency compression units • manual circulation of cold water for constant cold • dif shapes/configurations for body parts • filled cuff for compression • every 1-2 hours EDUCATE PT ON USE AT HOME Outcomes after specific agent • edema • pain • ROM (pre and post) • fxnal mvm • muscle guarding know these summary • dif modes, unique applications/benefits/risks • acute msk injuries • affects assessed in obj testing
