Abstract :
Fraktur perlu mendapat penanganan yang serius untuk mencegah
komplikasi dan timbulnya problematik yang dapat mengakibatkan gangguan
gerak dan fungsi seperti nyeri, atrofi dan kelemahan otot, kontraktur jaringan
lunak dan kekakuan sendi sehingga mempercepat ambulasi. Penelitian ini
dilakukan untuk membuktikan apakah terapi ultra sound (US) pulsed intensitas
0,5 watt/cm² lebih menurunkan nyeri weight bearing daripada 1,0 watt/cm² pada
pasca fraktur 1/3 tengah tibia.
Sampel penelitian berjumlah 16 orang pasien pasca fraktur 1/3 tengah
tibia, dua minggu setelah reduksi, laki-laki dan perempuan dengan bentuk fraktur
obliq dan spiral, yang diukur nyeri weight bearing dengan beban 25% berat
badan dalam skala nyeri visual analoque scale (VAS). Subjek penilitian
kemudian dikelompokkan secara random dalam dua kelompok. Kelompok
perlakuan diberikan intevensi US pulsed intensitas 0,5 watt/cm² setiap hari
selama dua minggu dan kelompok kontrol diberikan intervensi US pulsed
intensitas 1,0 watt/cm² setiap hari selama dua minggu. Pada kedua kelompok
diberikan kontraksi isometrik pada otot-otot tungkai dan pergelangan kaki
setelah dilakukan intervensi US. Penelitian dilakukan selama tiga bulan. Pada
akhir penelitian dilakukan pengukuran kembali nyeri weight bearing dengan
beban 25% berat badan dalam skala nyeri VAS.
Rerata nyeri weight bearing sebelum intervensi pada kedua kelompok
tidak menunjukkan adanya perbedaan yang bermakna (? > 0,05). Uji
pendahuluan pada kelompok perlakuan dapat disimpulkan bahwa intervensi US
pulsed 0,5 watt/cm² bermakna terhadap penurunan nyeri weight bearing pasca
fraktur 1/3 tengah tibia (? < 0,05). Sedangkan pada kelompok kontrol
menunjukkan bahwa intervensi US pulsed 1,0 watt/cm² bermakna terhadap
penurunan nyeri weight bearing pasca fraktur 1/3 tengah tibia (? < 0,05). Dari
uji komparasi dengan Paired Samples t-test menggunakan data selisi nilai VAS
antara kelompok perlakuan dengan kelompok kontrol sesudah intervensi
menunjukkan bahwa tidak ada perbedaan yang bermakna antara kelompok
perlakuan dan kelompok kontrol (? > 0,05). Intervensi US pulsed 0,5 watt/cm² dapat menurunkan nyeri weight bearing, hal yang sama ditemukan pula bahwa intervensi US pulsed 1,0 watt/cm²
dapat menurunkan nyeri weight bearing. Perbandingan terhadap hasil keduanya
menunjukkan bahwa tidak ada perbedaan yang bermakna antara kedua jenis
intervensi tersebut dalam menurunkan nyeri weight bearing pasca fraktur 1/3
tengah tibia.
Kata kunci: Nyeri VAS weight bearing, US pulsed 0,5 dan 1,0 watt/cm² / Fractures need to get serious treatment to prevent complications which
can lead to movement disorders such as pain and function, muscle atrophy and
weakness, soft tissue contractures, and joint stiffness s. The study was
conducted to prove whether the therapeutic ultrasound (U.S.) pulsed intensity
of 0.5 watts / cm ² to more reduce weight bearing pain than 1.0 watts / cm ²
after tibial shaft fracture.
The samples were 16 patients with post tibial shaft fracture, two weeks
after the reduction, male and female to form a spiral fracture and obliq, which
measured pain with weight bearing load of 25% weight loss in visual analoque
scale (VAS). The number of the subject of the research was alocated randomly
into two groups. The treatment group was treated the intensity pulsed U.S.
intervention 0.5 watts / cm ² per day for two weeks and the control group was
treated the intensity pulsed U.S. intervention 1.0 watts / cm ² per day for two
weeks. The second group was treated an isometric contraction of the muscles of
the leg and ankle after the U.S. intervention. The research was conducted over
three months. At the end of the research, measurements were taken on pain with
weight bearing load of 25% weight in the VAS pain scale. The average weight bearing pain before intervention in both groups showed no significant difference (? > 0.05). The initial test in treatment group, we can be concluded that a U.S. intervention pulsed 0.5 watts / cm ² significant
effect pain reduction in weight bearing after a tibial shaft fracture (? < 0.05).
The control group showed that the intervention of U.S. two pulsed 1.0 watts /
cm ² significant effect on pain reduction in weight bearing after a tibial shaft
fracture (? < 0.05). Based on the data from initial test, I conducted comparison
test with the Paired Samples t-test by using deviation data before and after
intervention from treatment group and control group. The result is the VAS
values was no significant difference between the treatment and control groups
(? > 0.05). U.S. intervention pulsed 0.5 watts / cm ² can reduce pain weight bearing,
the same is found also that the U.S. intervention pulsed 1.0 watts / cm ² can
reduce weight bearing pain. The comparison to both result shows that there was
no significant difference between the two types of such interventions in
reducing p
