ABSTRACT

This study use 123 Indonesian healthy adult subjects (58 males and 65 females) with sedentary lifestyle, aimed to produce maximum VO₂as a measurement tool of an Indonesian healthy adult functional capacity. Designed by using the followings: distance, height, body weight, sex, age, maximum heart rate of six minute walking test and lung capacity (FEV and FVC), resulted a good correlation except body weight (p > 0.05) with maximum VO₂. A new protocol of the six minute walking test used in this study gives a non significant difference result of distance compared to the golden standard value using Biodex^® gait trainer (p<0.05). Post hoc test of the new formula gave result of maximum VO₂that is relevant to the golden standard maximum VO₂using Cosmed^® C-P ex and has significant difference compared to Cahalin’s formula (p<0.05). Increase of serum lactic acid level after the six minute walking test proves the presence of muscle cellular metabolism. The increase of lactic acid less than 4mM which is an indicator of aerobic zone proves that the new protocol of the six minute walking test is a submaximum test.

Key words: maximum VO₂, Nury’s formula, Cahalin’s formula, Nury’s protocol, six miute walking test

ABSTRAK

Penelitian ini menggunakan 123 subjek (58 laki-lakidan 65 perempuan) dewasa sehat Indonesia dengan sikap hidup sedentary ,bertujuan memperoleh rumus prediksiVO₂ maksimal sebagai alat ukur kapasitas fungsi dewasa sehat Indonesia. Dirancang dengan memasukkan jarak tempuh disertai berturut-turut tinggi badan, berat badan, jenis kelamin, umur, denyut jantung tertinggi yang didapat dari ujijalan di lintasan dan kapasitas paru (VEP₁ dan KVP) setelah didapati berkorelasi baik kecuali berat badan (p > 0,05) dengan VO₂ maksimal. Protokol baru uji jalan enam menit yang digunakan pada penelitian memberikan hasil jarak tempuh yang tidak berbeda bermakna dengan nilai baku emas jarak tempuh menggunakan Biodex^® gait trainer (p<0,05). Padaujipost hocmenggunakanrumusbarudidapatihasilVO₂maksimal yang sesuai dengan baku emas VO₂ maksimal menggunakan Cosmed^® C-P ex, dan jika dibandingkan antara rumus baru dengan rumus Cahalin terdapat perbedaan yang bermakna (p<0,05). Peningkatan kadar laktat sesudah uji jalan enam menit, membuktikan terjadi peristiwa metabolisme selular pada otot. Kadar laktat yang tidak melebihi 4 mM, menunjukkan masih pada zona aerobik, memberikan bukti bahwa uji jalan enam menit menggunakan protokol baru merupakan uji submaksimal.

Abstract : The objective of this research is to enhance alternative of wound healing of diabetic foot ulcer using Low Level Laser Therapy, by evaluating the effect of Low Level Laser Therapy in the process of wound healing in diabetic foot ulcer. Research design using experimental clinical trial at Department of Physical Medicine & Rehabilitation, Metabolic & Endocrine clinic Department of Internal Medicine and inpatient ward of Dr Cipto Mangunkusumo Hospital, Jakarta. Subject of the research are 34 patients with diabetic foot ulcer, 17 in the intervention group and 17 in the control group. Both groups are homogen in terms of age distribution, BMI, duration of Diabetic Mellitus, level of HbA1C, duration of ulceration and initial ulcer size. Intervention group had standard wound dressing with NaCl 0.9% combined with Low Level Laser stimulation of 5 Joule/cm² , twice weekly. The control group had standard wound dressing with NaCl 0.9% twice weekly. Ulcer size was evaluated weekly for the duration of 5 weeks. The outcome parameter determined by changes in ulcer size and the result is the rate of wound healing in the intervention group was significantly higher than in the control group. It was found that wound dressing combined with Low Level Laser stimulation, can accelerate wound healing.

Abstract:The aim of this study is to get standard value of six-minute-walk test for children aged 9-10 years as well as exploring the correlation of sex, body weight, and height with walking distances. The standard value could later be used to measure functional capacity, monitor progress of disease, and response to treatment of disabled children. The subjects consist of 194 boys and 198 girls aged 9-10 years in Central Jakarta’s public elementary school. Baseline examination comprised of body weight, body height, vital signs, standard physical examination, and nutritional state with Epi Info. Walking instructions were given prior to the test. Vital signs were re-measured afterward. No significant difference found in the subject’s anthropometric characteristics. Consecutively, boys’ and girls’ walking distances were 500.08 meter and 481,82 meter. There was significant difference in walking distance between both sexes. There was weak and no significant correlation between body height, body weight, body mass index, and walking distance in boys and girls, except for girls’ body height. Vital signs had significant difference before and after test. Performing a six-minute-walk test is feasible, easy, and practical in children, but very dependant upon the child’s motivation and coordination.

Abstract : The purpose of this study is to compare the effect of electrical stimulation (ES) on strength of quadriceps femoris muscles in acute exacerbation and post acute exacerbation Chronic Obstructive Pulmonary Disease (COPD) patients. This is a pre and post test study without a control group. The ES was applied for 30 minutes on both sides of quadriceps muscles with duration of treatment in 4 weeks for all subjects. Muscle strength measurement was performed before and after intervention period. Muscle strength improved significantly on right side (by 154,60 ± 34,77 to 206,36 ± 32,47, p<0,05)>
