Abstract

Background: Foot Plate Orthosis (FPO) is an assistive device to prevent foot injuries. Carbon fiber is a commonly  used material. Although carbon fiber material provides many advantages, its dependence on imported raw  materials is an obstacle. Therefore, alternative materials that are easily available in Indonesia are needed. Jute  fiber has the potential to be a strong,elaticity and economical alternative. Objective: To analyze flexural strength properties of jute fiber composites as an alternative material for orthosis  foot plates. Methods: The study used a quantitative experimental design that included included creating composite  materials with woven of jute fiber, polyester resin using the lamination method. Variations in the number of  jute fiber layers were used to determine their effect on flexural strength. Flexural strength testing was conducted  using ASTM D790 standard. The test data was analyzed descriptively and statistically to determine the optimal  layers that provide the best flexural strength. Results: The test results show that the jute fiber composite with five layers produces the highest flexural strength,  which is 50 MPa. The increase in the number of layers is directly proportional to the increase in flexural strength  up to the optimum point at five layers. However, jute fiber composites tend to have lower elasticity than synthetic  materials such as carbon fiber. Conclusion: Jute fiber composites with the optimal number of layers have flexural strength as orthosis foot plate  materials, but their low elasticity limits their effectiveness in dynamic activities.

Abstract

Background: Football players with high running speeds will also have strong football skills. Over 50% of running activities are attributed to the ankle and foot. Running speed can be maximized with strong ankles. To keep the ankles healthy when running, ankle sleeves might be provided. One type of support for the ankle that applies the proper amount of pressure without being overly rigid or strong is an ankle sleeve. Because the ankle sleeve's function can limit excessive range of motion movements, improve alignment prior to initial contact, alter neuromuscular activity, and provide additional support that can prevent excessive movement, it is anticipated that the ankle will remain in good condition when running. Aim: The purpose of this study is to ascertain how wearing ankle sleeves affects football player’s running speeds. Method: One group pretest and posttest design in quantitative research. Thirteen individuals who wore ankle sleeves for four weeks made up the research sample. The paired sample T test is used for data analysis. Results: p = 0.001 (<0.05) for the analysis test. Conclusion: Football players' running speeds are impacted by the use of ankle sleeve.

Abstract

Background: Carpal tunnel syndrome (CTS) is a prevalent entrapment neuropathy among manual workers performing repetitive wrist loading and sustained precision grip. Cigarette-rolling workers face elevated risk due to prolonged wrist flexion and repetitive pinch activity. Despite the efficacy of wrist orthoses, conventional devices often provide suboptimal anatomical conformity and restrict occupational hand function. Three-dimensional printing enables patient-specific fabrication at low cost, yet clinical evidence in occupational rehabilitation remains limited. Aims: This study evaluated the fabrication workflow and clinical outcomes of a customized 3D-printed CTS wrist splint in a cigarette-rolling worker, focusing on efficiency, anatomical fit, cost, and functional performance. Methods: A single-case study design was employed consistent with established methodology for novel clinical workflow documentation, to evaluate practicability rather than population-level efficacy. The participant was a 38-year-old female with mild-to-moderate right-hand CTS. A CAD-designed PLA+ orthosis was fabricated via FDM 3D printing and hot-water thermoforming. Primary outcomes wrist posture, pain, fatigue, endurance, and comfort were assessed at baseline, post-fitting, Day 7, and Day 14 via structured observation and KPOP Plus telemonitoring. Results: Digital fabrication required 384 minutes and 60.31 g of PLA+ at a material cost of IDR 16,200. Wrist posture improved to near-neutral alignment, while pain, fatigue, and endurance improved without skin complications. Telemonitoring confirmed sustained symptom relief and device comfort through Day 14. Conclusion: Digitally fabricated 3D-printed wrist orthoses were feasible, clinically beneficial, and cost-effective for occupational CTS management. This case demonstrates an integrated workflow combining CAD design, FDM printing, thermoforming, and telemonitoring.

Abstract

Background: Ankle-Foot Orthoses (AFOs) are widely used to improve gait in children with cerebral palsy (CP), yet their effects are multidimensional and vary across functional, independence, and user-centered domains. This study synthesizes clinical outcomes from a diverse CP cohort to inform an integrated, evidence-based approach to AFO prescription. Methods: We conducted a descriptive observational analysis of 40 children with CP using AFOs. Measurements included GMFCS-based functional status, independence with PEDI-2, and comfort/satisfaction with QUEST. Normality was assessed with the Shapiro–Wilk test. Group comparisons between rigid and jointed AFO designs were analyzed with the Mann–Whitney U test; effect sizes were reported as r. Regression analyses identified predictors of independence and comfort. An integrated outcome framework and clinical decision algorithm were developed to guide prescription. Results: The sample (mean age 7.80 ± 4.42 years; mean AFO use 4.56 ± 4.09 years) showed multidimensional effects of AFO design. Rigid AFOs yielded higher GMFCS scores (functional benefit) and a clustering of higher-function outcomes, whereas jointed AFOs achieved greater comfort (QUEST: r ? 0.34) and a broader distribution of satisfaction. Independence (PEDI-2) did not differ significantly by AFO type (p = 0.283; r = 0.17), indicating multifactorial determinants beyond device design. Regression indicated age as a strong predictor of independence, and AFO design as a key predictor of comfort. An integrated framework mapped rigid AFO to function, jointed AFO to comfort/independence, and highlighted the role of wear-time in real-world effectiveness. Conclusion: AFO effectiveness in CP is multidimensional; rigid designs may enhance functional stability while jointed designs improve comfort and potential adherence, influencing participation. An individualized, goal-directed prescription that balances biomechanical control with user-centered outcomes is essential for optimizing short-term performance and long-term participation.

Abstract

Background: The Health Polytechnic of the Ministry of Health Surakarta provides extracurricular programs to support students’ non-academic development, including the Martial Arts Student Activity Unit. Kicking techniques are the dominant component in martial arts and require high agility, defined as the ability to rapidly change direction to evade attacks and execute effective counterattacks. These movements involve repetitive loading of the knee joint, increasing the risk of overuse injury and decreased functional performance. Knee sleeves, made of elastic materials, provide compression and thermal support that may enhance joint function. Previous studies report benefits such as pain reduction, improved proprioception, and increased knee stability. Aims: To determine the effect of knee sleeve use on agility among students participating in the Martial Arts Student Activity Unit. Methods: A true-experimental study using a pre-test and pot-test control group design, in which participants were randomly allocated to groups, with a randomized controlled trial design was conducted involving 32 students, divided into experimental and control groups (n=16 each). Agility was measured using the T-Test. Data were analyzed using paired-sample t-tests to assess within-group pre-post changes and independent-sample t-tests to compare the experimental and control groups. Results: Agility improved in both groups after the intervention, but the improvement was significantly greater in the knee sleeve group than in the knee sock (control) group (p= 0.031), indicating that knee sleeve use provides an additional benefit for agility beyond that of standard knee socks. Conclusion: Knee sleeve use has a significant effect on improving agility and may help reduce the risk of overuse injuries during martial arts training.   Keywords: Knee sleeve; Agility; Kicking
