Answer

Answer

Water immersion therapy is used for cardiovascular, respiratory, and orthopedic conditions and also appears to benefit some neurologic patients, although little is known about how it affects neural activity. Sato et al examined the effect of water immersion on median nerve SLSEPs and found that immersion significantly reduced SLSEP components known to originate in several cortical areas. This attenuation suggests that water immersion influences the cortical processing of somatosensory inputs. [43]
