ABSTRAK
Kanker payudara adalah kanker pada jaringan payudara. Kanker ini merupakan kankeryang paling umum diderita wanita. Pengalaman dan pengobatan kanker tersebutmempunyai pengaruh yang besar dalam kualitas hidup pasien, seperti kelemahan,nausea dan nyeri. Efek samping atau keluhan dari kanker dan pengobatannya cenderungmeningkat selama perawatan dan dapat menetap selama berbulan-bulan atau bertahuntahun.Untuk mencapai proses penyembuhan dan pemulihan yang baik pada pasienkanker payudara pasca mastektomi perlu adanya manajemen nyeri yang tepat. Penelitianini bertujuan mengidentifikasi pengaruh latihan fisik terhadap nyeri pada pasien kankerpayudara pasca mastektomi di RSUD Dr. Achmad Mochtar Bukittinggi. Desainpenelitian ini adalah quasi eksperiment, khususnya non-equivalent control group denganpre dan post test. Sampel berjumlah 30 orang (15 orang kelompok intervensi yangdiberikan 7 hari latihan fisik ditambah analgesik dan 15 orang kelompok kontrol yangdiberikan terapi standar analgesik), yang diambil dengan metode non probabilitysampling jenis consecutive sampling. Evaluasi tingkat nyeri dilakukan setiap hari baikpada kelompok intervensi maupun kelompok kontrol. Hasil penelitian diperoleh adanyapenurunan tingkat nyeri setiap harinya, baik pada kelompok intervensi maupun kelompokkontrol. Penurunan yang lebih besar terjadi pada kelompok intervensi (p=0,000), artinyalatihan fisik pada pasien kanker payudara pasca mastektomi dapat berpengaruh terhadappenurunan tingkat nyeri. Rekomendasi hasil penelitian ini perlu adanya penelitian lanjutdengan jumlah sampel yang lebih besar dan dilanjutkan dengan perawatan di rumah sertadapat di jadikan salah satu intervensi keperawatan dalam menangani manajemen nyeripasca mastektomi.

ABSTRACT
Breast cancer is one of the common types of cancer among women. The trajectory of theexperience for having the disease and its trestment are believed to produce a big effect onthe quality of life of the patients. The experiences such as weaknesses, nauseated, andpain have to be through by the patients on the daily bases. This side effects andcomplaints created form the cancer and its therapy tend to increase during hospitalizationand can be pertinent for months or ever years. Therefore, to achieve a better healing andrecovery processes for the breast cancer patients especially post mastectomy requires theright pain management.The purpose of this study is to identify the effect of physical exercise on pain perceivedby the breast cancer patient after mastectomy at Dr Achmad Mochtar General Hospital,Bukittinggi. The design was a quasi experimental using a non-equivalent control groupwith pre and post test approach. There was 30 subjects participated in the study dividedtwo groups (the intervention group was provided with analgesic and seven days physicalexercise; and, the control group was provided with analgesic only); 15 subjects for eachgrup. A non probability sampling method-consecutive type was utilized to gather thesubjects. The pain was evaluated each day to both groups.The findings of the study demonstrated that there is a daily pain reduction between bothgroups. Further, the comparison of the pain reduction between these two group leads tothe bigger pain reduction in the intervention group compared to the control group(p=0.000). This finding showed that the physical exercise provided to the postmastectomy-breast cancer patients has a significant effect to reduce the pain level. Thiswith home care; also this finding can be used as a foundation to involve physicalexercise as on of the nursing intervention in managing post mastectomy pain commonlyexperienced by breast cancer patients.
