Background: The majority of people who work as tea plantation pickers are powerful. They carry heavy loads of tea on their backs while the roads are quite dangerous and sometimes cause problems. A balance training program has proven to reduce postural sway, increasing leg muscle strength and improving balance strategies. Objective:The aim of this study was to determine the effect of Vladimir Janda balance training methods with an external load on postural sway and leg muscle strength of tea pickers. Methods: The study design used was quasi-experimental with a randomized control group pretest-posttest design. Subjects were tea pickers consisting of a productive age group of 15 people and 15 people as a control treatment group. The Vladimir Janda method balance exercises were conducted over five weeks consisting of 5 phases. Phase I-IV were carried out 5 times a week, while the V phase was done 3 times a week and each session lasted 15 minutes. Postural sway was measured with a posturometer. Leg muscle strength was measured by a back-leg dynamometer. The statistical tests used were Independent T-test and the Mann-Whitney test. Results:The statistical test for the control and treatment groups using the Mann-Whitney test showed p = 0.001, meaning no external load effects on postural sway. Independent t-test showed p = 0.000, meaning there are differences in the effect between the treatment and control groups after being given balance exercises to increase leg muscle strength. Logistic regression test results obtained the ROC value of 0.917, meaning the Vladimir Janda balance training can affect the postural sway and knee extensor muscle strength by 91.7%. Conclusion: The Vladimir Janda balance exercise method can reduce postural sway and increase the strength of knee extensor muscles and ankle flexor Dorsi muscles. External loads can affect the postural sway.
Latar Belakang: pada pasien geriatri terjadi perubahan besar yang terkait dengan penuaan manusia yaitu penurunan massa otot secara progresif, yang dapat mengakibatkan terjadinya penurunan kekuatan dan fungsionalitas tubuh. Sarcopenia dapat menjadi salah satu faktor risiko jatuh pada lansia disamping faktor bertambahnya usia, penggunaan obat, gangguan kognitif dan defisit sensorik. Tujuan mengetahui gambaran sarcopenia dan risiko jatuh pada pasien geriatri. Metode pencarian literature melalui Pubmed dan Google Scholar didapatkan 26 artikel mengenai sarcopenia dan risiko jatuh pada pasien geriatri. Hasil: Sarkopenia merupakan penurunan massa otot rangka yang terkait dengan usia yang diikuti dengan adanya penurunan kekuatan dan/atau fungsi otot. Usia semakin lanjut akan menurunkan massa otot akibatnya bisa menyebabkan meningkatkan risiko jatuh dan sarcopenia. Sebanyak sepertiga dari lansia akan mengalami kejadian jatuh setidaknya sekali selama setahun. Kondisi sekunder dari kejadian jatuh dapat meningkatkan risiko dari cedera akibat jatuh (misalnya, patah tulang pinggul dan cedera kepala). Salah satu cara yang cukup efektif untuk menurunkan angka kejadian jatuh adalah dengan mempraktikkan gaya hidup sehat, menghindari stress, melakukan kegiatan latihan fisik. Simpulan: Sarcopenia yang diperparah dengan adanya penurunan aktivitas fisik, dapat menyebabkan penurunan fungsi organ tubuh secara keseluruhan yang dapat mengakibatkan terjadinya kejadian jatuh pada lansia.
