PERBANDINGAN HASIL APLIKASI TENS DAN LATIHAN VOLUNTER TERHADAP KEMAMPUAN DAN DURASI KONTRAKSI MAKSIMAL OTOT DASAR PANGGUL PADA WANITA LANSIA

Abstract

Kesoema, TA. A comparison of the outcome of TENS application and voluntary exercise on the ability and duration of maximal contraction of pelvic floor muscles in elderly women. Objective: To compare the outcome of TENS application and voluntary exercise on the ability and duration of maximal contraction of pelvic floor muscles. Design: An experimental trial with pre and post test design. Participants: thirty-four elderly women, aged range 60 to 65 years. They were randomly divided into 2 groups, the first group conducted voluntary exercises (18 subjects) and the other group was given a TENS application program (16 subjects). Settings: Nursing home of Pucang Gading and elderly group of GKMI Demak. Time: February — May 2004. Interventions: The group of voluntary exercises underwent a program of Kegel exercise and its modification. It consists of voluntary contractions of pelvic floor muscles for 6 seconds/counts, 15 repetitions and 5 sessions per day. The group of TENS application was given a program of electrical stimulation with TENS. Two electrodes placed on the abdomen just above the lateral portion of the inguinal ligament, two others placed under the gluteal fold toward the medial side of posterior aspect of the thigh. TENS was set at frequency of 60 Hz, duration of 150 gs, amplitude of 80 mA with firing mode of burst mode for 15 minutes per day. Each group finished 28 intervention programs. Main outcome measures: The ability and duration of pelvic floor muscles to make maximal contractions which be noted from PFX before and after interventions. Results: Both groups showed a significant increase of pelvic floor muscles ability to contract maximally (p<0,05). The increase of pelvic floor muscles ability to contract maximally at the group of voluntary exercise is significantly higher than the TENS group (p<0,05). The duration of maximal contraction of pelvic floor muscle is significantly increase (p<0,05). However, the group of TENS application did not get a significant increase on the duration of maximal contraction of the pelvic floor muscles (p>0,05). Comparing with TENS group, the voluntary exercise group produced significantly greater period in duration of pelvic floor muscles maximal contraction (3.78 vs. 1.63) Conclusion: Compared with TENS application, voluntary exercise gives more benefit in increasing the ability and duration of maximal contraction of pelvic floor muscle.

Perbandingan hasil aplikasi TENS dan latihan volunter terhadap kemampuan dan durasi kontraksi maksimal otot dasar panggul pada wanita lansia.Karya ilmiah penelitian. 2004; 1-59. membandingkan basil aphicasf LENS dan latihan volunter terhadap kemampuan dan durasi kontraksi maksimal otot dasar panggul. Rancanaan: Pre and post test design. Partisipan: tiga puluh empat subyek wanita lansia, usia berkisar 60-65 tahun, dibagi secara acak ke dalam 2 kelompok, yaitu kelompok latihan volunter (18 subyek) dan kelompok aplikasi TENS (16 subyek). Tempat: Panti Wredha Pucang Gading dan Kelompok Lansia GKMI Demak. Waktu: Februari 2004 sampai Mei 2004. Perlakuan: Kelompok latihan volunter mendapatkan program latihan Kegel dan modifikasinya dengan melakukan kontraksi volunter selama 6 detik dengan 6 hitungan, 15 kali repetisi dan 5 sesi per hari. Kelompok aplikasi TENS mendapatkan stimulasi listrik dengan 2 elektroda diletakkan pada sisi lateral ligament= inguinalis kanan dan kiri, sedangkan 2 lainnya di lipat gluteal sisi medial paha kanan dan kiri. TENS diberikan dengan frekuensi 60 Hz; durasi 150 gdtk, amplitudo 80mA dan model letupan burst mode selama 15 menit/hari. Kedua kelompok menyelesaikan 28 kali perlakuan. Hasil Pengukuran Utama: Kemampuan dan durasi kontraksi maksimal otot dasar panggul yang tercatat dari alat PFX sebelum dan sesudah perlakuan. Hasa: Sesudah perlakuan, baik kelompok latihan volunter maupun kelompok TENS terdapat peningkatan kemampuan kontraksi maksimal otot dasar panggul secara bermakna (p<0,05). Kemampuan kontraksi otot dasar panggul pada kelompok latihan volunter secara bermakna lebih besar daripada kelompok TENS (p<0,05). Durasi kontraksi maksimal pada kelompok latihan memperlihatkan peningkatan yang bermakna (p=0,000) sedangkan pada kelompok TENS tidak terlihat adanya peningkatan yang bermakna (p=0,188). Dibanding kelompok TENS, kelompok latihan volunter menghasilkan durasi kontraksi maksimal yang lebih besar secara bermakna (3,78 vs. 1,63). Kesimpulan: Dibandingkan dengan aplikasi TENS, latihan volunter otot dasar panggul memberi manfaat yang lebih besar dalam meningkatkan kemampuan dan durasi kontraksi maksimal otot dasar panggul.
