In facilities where a track required is not available for gait speed test, a simpler method using a shorter track and test duration is needed. One of such methods is the 4-meter gait speed. This study aimed to determine the cut off values for 4MGS and its correlation with the 6-minute walk test (6MWT), a more common functional performance test with shorter track and time. Data for this study were collected at the Department of Rehabilitation of Dr. Cipto Mangunkusumo General Hospital during the period of August 2016 to March 2017. The consecutive sampling approach was used to recruit healthy Indonesian adults (n=61) aged 18–50 years into this cross sectional study. The anthropometric and respiratory variables were measured as descriptive data and the cut-off values were determined by calculating the mean 4-meter gait speed (4MGS)-2SD for each gender. The 6MWT was performed afterwards to assess the correlation between 4MGS and 6-minute walk distance (6MWD). Results presented a mean 4MGS value of 2.114±0.309 m/s (male) and 1.908±0.227m/s (female) with the cut-off values for normal gait speed of 1.496 m/s and 1.454m/s for male and female, respectively. Factors affecting 4MGS were body height, body weight, forced vital capacity (FVC), and forced expiratory volume in 1 second (FEV1). The 4MGS is only shown to be weakly correlated with 6MWD (r=0.314, p=0.014). The cut-off values for 4MGS can be used as a reference to assess the normality of gait speed as a parameter of functional mobility in healthy Indonesian adults and should be used in adjunct to 6MWT to represent a comprehensive functional capacity status.

Introduction: Osteoarthritis (OA) of the knee causes disability due to pain and will affect the functional ability to walk. Low-Level Laser Therapy (LLLT) has been shown to reduce pain in knee OA, while High Intensity Laser Therapy (HILT) is able to reach deeper joint areas. Method: This study aimed to compare the effect differences between LLLT and HILT on pain and functional capacity in knee OA. Methods: This is a double-blind randomized controlled trial with 61 subjects randomized into LLLT (n=31) and HILT (n=30) groups. All the subjects were knee OA patient with Visual Analog Scale (VAS) ≥ 4. The laser therapy and exercise were given 3 times per week for 6 sessions. The pain scale evaluated using VAS and functional ability evaluated using 50-feet walk test. Result: After 6 sessions, both LLLT and HILT group showed reduced VAS score [∆VAS Score LLLT = 3 (2 – 4), HILT = 3 (2 – 5)] and increased walking speed (∆ walking speed for LLLT = 0.23 (0.02 – 1.24) m/s, HILT = 0.22 (0.08 – 0.7) m/s) which were statistically (p < 0.001) and clinically significant. HILT group had faster walking speed and greater VAS reduction compared to LLLT group (p < 0.001), but there was no significant difference in walking speed between two groups (p=0.655). Conclusion: HILT and LLLT combined with exercise were effective in reducing pain and increasing functional ability in knee OA after 6 sessions of intervention. Pain and functional ability improvement was faster and greater in HILT group than LLLT group.

Background/ObjectiveIn the field of Physical Medicine and Rehabilitation, it is essential to measure individual functional capacity, which could be evaluated through walking tests. Aside from the commonly used six minutes walking test (6MWT), four meter gait speed (4MGS) are widely used for its practicality. This study aimed to assess the agreement between 4 MGS and the 6MWT in Indonesian healthy adults.MethodsThis agreement analysis study had recruited 61 healthy and sedentary Indonesians aged 18 until 50 years old, and they were instructed to perform three tests, namely 6MWT and 4MGS with six meters and eight meters track. These gait speed were then compared to assess validity.ResultsMean gait speed results for males in 6MWT is 1.602 m/s, whereas 4MGS in six meter track is 2.114 m/s and similarly 2.108 m/s in the eight meter track. Females on the other hand, achieved 1.462 m/s for 6MWT, 1.908 m/s and 1.986 m/s for 4MGS in six and eight meter simultaneously. Bland Altman Agreement test between the 6MWT and 4MGS shows scatter dots with close limit of agreement, thus showing a good agreement between the 6MWT and 4 MGS with both tracks.DiscussionBoth track length of 4 MGS were in a good agreement with 6MWT for functional capacity assessment.ConclusionsIn response to the COVID-19 pandemic era, shorter track of 4MGS (six meters) can be feasibly utilized. It is evident that shorter duration and track will boost the tests practicality in assessing functional capacity for both inpatient and outpatient settings.

Introduction: St. George’s Respiratory Questionnaire (SGRQ) is a measuring tool to assess the quality of life of people with chronic obstructive pulmonary disease or various respiratory disorders. This study aimed to assess whether The Indonesian version of SGRQ was valid and reliable for subjects with chronic obstructive pulmonary disease (COPD). Methods: The Indonesian version of SGRQ was analyzed using a correlation test between SGRQ and sixminute walk distance (6 MWD) for validity. The reliability test was done using the test re-test reliability test by Spearman’s rank correlation, and Cronbach’s alpha for internal consistency. Results: Twenty-two patients eligible COPD patients were included in this study. There is a correlation between SGRQ’s component and 6MWD on activity (r= 0.49), impact (r= -0.58) and total SGRQ (r=-0.56). The SGRQ re-measurement test shows a strong correlation on the symptom (r = 0.76), activity (r = 0.58), impact (r = 0.51), total (r=0.58) and Wilcoxon test result shows there were no significantdifferences among subscales except total value p = 0.049. High internal Cronbach’s alpha consistency was approximately 0.73 to 0.86. Conclusion: The Activities and Impacts of Indonesian version of SGRQ component provides a picture of the validity to functional capacity. The Indonesia version of SGRQ is also proven to have good repeatability with high internal consistency.
