Learned non-use : ウィキペディア英語版 | Learned non-use Learned non-use of a limb is a learning phenomenon whereby movement is suppressed initially due to adverse reactions and failure of any activity attempted with the affected limb, which then results in the suppression of behavior. Continuation of this response results in persisting tendency and consequently, the individual never learns that the limb may have become potentially useful.〔Taub, E., Uswatte, G., & Pidikiti, R. (1999). Constraint-induced movement therapy: A new family of techniques with broad application to physical rehabilitation. Journal of Rehabilitation Research & Development, 36(3), 1–21.]〕〔Kunkel, A., Kopp, B., Muller, G., Villringer, K., Villringer, A., Taub, E., & Flor, H. (1999). Constraint-induced movement therapy for motor recovery in chronic stroke patients. American Academy of Physical Medicine and Rehabilitation, 80, 624–628.〕〔Grotta, J. C., Noser, E. A., Ro, T., Boake, C., Levin, H., Aronowski, J., & Schallert, T. (2004) Constraint-induced movement therapy. Stroke, 35, 2699–2701.〕 By constraining the less-affected limb there is a change in motivation, which overcomes the learned nonuse of the more-affected limb.〔 The principles of constraint-induced movement therapy (CIMT) used in stroke patients are based on the idea of the reversal of learned non-use.〔Liepert, J., Miltner, W. H. R., Bauder, H., Sommer, M., Dettmers, C., Taub, E., & Weiller, C. (1998). Motor cortex plasticity during constraint-induced movement therapy in stroke patients. Neuroscience Letters, 250, 5–8.〕 CIMT uses constrained movement of the less-affected limb and intensive training of the paretic arm to counter-condition the nonuse of the more-affected arm learned in the acute and early sub-acute periods.〔〔Schaechter, J. D. (2004). Motor rehabilitation and brain plasticity after hemiparetic stroke. Progress in Neurobiology, 73, 61–72.〕 ==See also==
