Abstract
Although instruments to measure footwork ability in sports performance have been investigated in previous studies, an instrument relevant to the movement characteristics of Tarung Derajat martial arts has not been found. The purpose of this study was to develop a sensor-based footwork instrument for Tarung Derajat martial arts. This study began with determining the elements of the instrument, design, selection of physical elements to be measured, sensor device components, assembly of the device, characterization of the relevance of movement in Tarung Derajat martial arts, and testing. The feasibility test of the device involved 4 experts (instrumentation, sports measurement tests, Tarung Derajat martial arts, and information technology) and 6 Tarung Derajat martial arts athletes (aged 18.53 ± 0.52 years). Then the test-retest reliability involved 33 Tarung Derajat martial arts athletes, consisting of male (n = 19; aged 19.21 ± 0.71 years) and female (n = 14; aged 18.79 ± 0.80 years). Data were analyzed using percentages, correlations, and t-tests. The results of the study showed that the sensor-based footwork instrument was very feasible to be used for Tarung Derajat martial arts, with a percentage of 86.50. The results of the test-retest reliability showed a high correlation coefficient (n = 33; r = 0.897; Sig. < 0.05; n = 19; r = 0.802; Sig. < 0.05; n = 14; r = 0.823;            Sig. < 0.05). Then, the t-test showed that there was no significant difference in the results of the footwork ability test between male and female participants (Sig. > 0.05). Field trials with wider subjects are needed in future research, with more refined tool displays and designs.

Abstract
Background and Study Aim. Low Back Pain (LBP) is an abnormal condition in the lower back which is accompanied by a painful sensation so that it will experience limitations in moving.Therefore, the need for special treatment in dealing with Low Back Pain (LBP) in order to reduce pain. Material and Methods. This research is a pre-experimental research using the approach one group pretest and posttest design. In this study, the results of the initial test data (pretest) were measured in the form of low back pain results with VAS, Modified Schober Test, Fingertip to Floor, and ODI, then giving treatment by combining deep tissue massage with stretching. Therapy is given to patients 3 times a week for 3 weeks, then the final data measurement (Posttest) is carried out. The subjects of this study were patients at the LKP Rumah Sehat Mandiri clinic for the last 5 months who had experienced low back pain injuries. Sampling in this study used purposive sampling so that there were 20 people with an age range of 20-60 years. The analysis in this study uses the SPSS Version 26 application. Results. The results showed that the indicators of pain, flexion, extension, right flexion, left flexion and function had a significant effect using a combination of deep tissue massage and stretching with a significant value si showing 0.000 < 0.05. In the left flexion indicator, a significance value of 0.001 < 0.05 was obtained, so it can be concluded that there is a significant difference in the deep tissue massage combination of stretching treatment. Conclusions. The results of this study provide evidence that the combination of deep tissue massage and stretching provides a significant reduction in the healing of low back pain injuries in patients. That way a combination of deep tissue massage and stretching can be applied to treat low back pain injury healing.
