RESUMEN
@#Objective To compare the effect of Shaker exercise and Chin Tuck Against Resistance(CTAR)exercise on dysphagia after radiotherapy for nasopharyngeal carcinoma(NPC).Methods From August,2015 to February,2017,90 patients with dysphagia after radio-therapy for NPC were randomly divided into control group,Shaker group and CTAR group equally.The control group received routine swal-lowing training,while the Shaker group accepted Shaker exercise and CTAR group accepted CTAR exercise in addition.They were assessed with Penetration-Aspiration Scale under video fluoroscopic swallowing study(VFSS)before,and two weeks,four weeks and six weeks af-ter exercise.Results There was no significant difference in VFSS score among the three groups before intervention(F=0.551,P>0.05).The score decreased after intervention in Shaker group and CTAR group(F>5.317,P<0.001),but varied less in the control group(F=1.774,P>0.05).However,it was less in Shaker group and CTAR group than in the control group(P<0.001),and it was not significantly different be-tween Shaker group and CTAR group after 4 weeks and 6 weeks of intervention (P>0.05).The total effective rate was 86.67% in CTAR group and 76.67% in Shaker group,that was significantly higher than 43.33% in the control group(χ2>2.079,P<0.05),and it was not signifi-cantly different between Shaker group and CTAR group(P>0.05).Conclusion CTAR exercise is effective on dysphagia after radiotherapy for NPC,which is similar to those of Shaker exercise,and more acceptable and easier to persist.
