Tennis elbow, or lateral epicondylitis, is an inflammatory condition of the lateral epicondyle commonly caused by repetitive overuse of the forearm extensor muscles. It is characterized by pain, limited joint range of motion, decreased muscle strength, and reduced functional capacity. Physiotherapy interventions, particularly ultrasound and exercise therapy, have been widely applied to reduce pain and restore functional performance. This study employed a case study design involving a 42-year-old female patient diagnosed with left-sided tennis elbow. The intervention was conducted over four therapy sessions. The modalities consisted of ultrasound, providing thermal and micromassage effects to reduce pain, combined with exercise therapy, including passive stretching to increase soft tissue flexibility and eccentric exercise to improve tendon strength and function. After four sessions, the patient showed significant improvement, including reduced pain during movement and palpation, increased joint range of motion in elbow flexion-extension, forearm pronation-supination, and wrist dorsiflexion-palmarflexion. Muscle strength, particularly in the extensors, pronators, supinators, and wrist dorsiflexors, also improved. Functional activity, measured using the PRTEE scale, demonstrated notable enhancement from mild disability to better functional independence. The combination of ultrasound, passive stretching, and eccentric exercise is effective in reducing pain, enhancing range of motion, strengthening muscles, and improving functional ability in patients with left-sided tennis elbow.

Hypertension in the elderly is one of the common and significant health problems. The purpose of this study was to determine the effect of elderly exercise on hypertension in the working area of ​​the Krueng Barona Jaya Aceh Besar Community Health Center. The study method applied was a quasi-experimental design through a pre-test-post-test approach with a total population of 413 hypertension sufferers and a total sample of 15 people. The sample collection method was through Snowball Sampling. This research was conducted on April 20-24, 2025 in Meunasah Village, Papeun, with the research instrument in the form of an observation sheet with a measuring instrument using a sphygmomanometer. First, blood pressure was measured before the intervention, using a blood pressure monitor. Next, the elderly were given 20 minutes of exercise, followed by another 30-minute evaluation to assess changes in blood pressure. The results showed that before being given elderly exercise activities, the average systolic blood pressure of respondents was 179.60 mmHg and diastolic blood pressure was 102.73 mmHg, while after being given elderly exercise activities, the average systolic blood pressure of respondents was 170.80 mmHg and diastolic pressure was 92.80 mmHg with a difference of 8.8 mmHg systolic blood pressure and 10.13 mmHg diastolic blood pressure using a paired t-test of ρ value 0.000 (ρ <0.05). The conclusion is that there is an effect of elderly exercise on hypertension. It is hoped that hypertension sufferers and researchers will carry out routine elderly exercise activities, educational institutions will provide books on hypertension and complementary materials to increase students' knowledge and insight, and further research will be able to use the findings of this study as reference material and can improve this study through different variables.

Waist circumference is a method used to determine central obesity, which is a condition of excess fat accumulation in the abdominal area, resulting in abnormal waist circumference in women >80 cm and men >90 cm. This study aims to determine the difference in effectiveness between prone plank exercise and bicycle crunch exercise in reducing waist circumference in adolescents. The research method used a quasi-experimental pretest-posttest two-group design. The sample consisted of 24 participants, divided into Group I (prone plank exercise) and Group II (bicycle crunch exercise), with each group consisting of 12 participants. Both groups underwent exercise therapy for 4 weeks, with a frequency of 5 times per week, with an intensity of 30 seconds per set, repeated 3 times. The measurement tool used was a calibrated midline. The results showed that Group I (prone plank exercise) experienced a reduction in waist circumference of 5.75 cm, while Group II (bicycle crunch exercise) had a reduction of 7.91 cm, indicating that both exercise therapies have an effect on waist circumference reduction. The difference test between groups resulted in p>0.05 (p=0.747), meaning there is no significant difference between the two exercise types.

Health problems in older adults, particularly oral function disorders, often lead to serious complications such as chewing difficulties, which disrupt adequate nutritional intake and may trigger broader health issues including malnutrition, aspiration pneumonia, and a decline in overall quality of life. One intervention that has been introduced to address these challenges is the PATAKARA exercise, a simple oral rehabilitation technique designed to strengthen oral and facial muscles. This study aimed to analyze the effect of PATAKARA exercise on the oral function of older adults at Roujin Home Seseragi No Sato Zao, Japan. The research employed a quasi-experimental approach with a One Group Pretest-Post Test Design. The study population consisted of 75 older adults, with 40 participants selected through purposive sampling. Data were collected using the Oral Health Impact Profile-14 (OHIP-14) questionnaire and analyzed with the Wilcoxon test. Findings showed that most participants were in the advanced elderly category (≥80 years), predominantly female, and had a secondary education background. Prior to the intervention, the majority exhibited moderate oral function, while after the exercise, most participants demonstrated improved oral function categorized as good. Statistical analysis revealed a significant effect of the PATAKARA exercise on oral function (p = 0.000). The results suggest that PATAKARA exercise effectively enhances oral muscle strength, including the lips, tongue, pharynx, and larynx, thereby improving chewing, swallowing, and speech functions. This exercise can be recommended as a practical, non-invasive, and low-cost intervention to support oral health and overall well-being among older adults.

Diabetes Mellitus (DM) is a chronic metabolic disorder that is rapidly increasing globally and is associated with a high risk of peripheral arterial complications. The Ankle Brachial Index (ABI) is a simple and reliable tool for screening peripheral arterial disease, while foot exercise represents a practical, low-cost, and non-pharmacological intervention to improve peripheral perfusion. This study aimed to evaluate the effectiveness of foot exercise in improving ABI values among hospitalized patients with DM. A pre-experimental one-group pretest-posttest design was implemented with 26 purposively selected inpatients with DM. Participants performed standardized foot exercises once daily for 15 minutes over two consecutive days. ABI values were measured using a sphygmomanometer and vascular Doppler before and after the intervention, and data were analyzed using a paired t-test. The mean ABI significantly increased from 0.707 (SD = 0.031) to 0.884 (SD = 0.027) (p < 0.001), indicating a clinically meaningful improvement from moderate impairment to near-normal circulation. These results demonstrate that foot exercise is effective in improving ABI values among hospitalized DM patients. The study highlights foot exercise as a safe, simple, and non-pharmacological nursing intervention that can be recommended in inpatient care settings to improve peripheral perfusion and prevent further complications related to peripheral arterial disease. This intervention offers a promising approach to managing peripheral arterial complications in diabetic patients

Introduction: The increase in life expectancy among the elderly has directly contributed to the rise in the global elderly population. According to global data, the number of elderly individuals is projected to reach 1.4 billion by 2030. This demographic growth is often accompanied by various health problems associated with aging, such as the decline in vital organ function and the emergence of degenerative diseases. One of the most common degenerative diseases among the elderly is hypertension. Hypertension is widely known as a “silent killer” because it can lead to serious complications, including stroke and heart disease, if not managed properly. A common complaint experienced by individuals with hypertension is headache, particularly in the posterior region, which significantly affects the patient’s quality of life. Management of hypertension can be carried out through pharmacological therapy with antihypertensive drugs as well as non-pharmacological interventions. One of the non-pharmacological approaches increasingly being applied is isometric handgrip exercise, which involves static muscle contractions performed at light to moderate intensity. Method:This study aimed to evaluate the effect of isometric handgrip exercise on pain reduction in patients with hypertension. The research design employed a descriptive case study involving one individual with hypertension who experienced pain complaints. The study was conducted on September 16–18, 2024, at Roujin Home X. The instruments used included observation, interview, and the provision of isometric handgrip exercise therapy. Pain measurement was carried out using a numerical rating scale before and after the intervention. Results:The three-day intervention demonstrated a significant reduction in pain levels. On the first day, the patient reported a pain score of 6, which decreased to 4 on the second day, and further declined to 2 on the third day after the intervention. Conclusion:The findings of this study indicate that isometric handgrip exercise is an effective non-pharmacological method for alleviating acute pain in patients with hypertension. This simple intervention has the potential to be applied as a complementary therapy in elderly care facilities to improve the quality of life of individuals living with hypertension.

          During the second and third trimesters of pregnancy, as fetal development progresses, pregnant women often experience lower back pain. This condition not only causes discomfort but also affects daily activities and overall quality of life. One of the non-pharmacological approaches believed to reduce lower back pain is prenatal exercise. This study aims to evaluate the effect of pregnancy exercise on reducing lower back pain among pregnant women in the second and third trimesters. This research employed a quasi-experimental design with a pre-post test approach without a control group. The sample consisted of 28 pregnant women in their second and third trimesters who met the inclusion criteria and reported experiencing lower back pain. Pain levels were assessed before and after the intervention using a valid and reliable pain scale. Data were analyzed using appropriate statistical tests, particularly the paired sample t-test. The findings revealed that the mean pain score before the intervention was 3.32 with a standard deviation of 0.772. After the intervention, the mean pain score decreased to 2.25 with a standard deviation of 1.005. Results of the paired t-test indicated a p-value of 0.000 (p < 0.05), demonstrating a significant difference in pain levels before and after pregnancy exercise. These results indicate that pregnancy exercise is effective in reducing lower back pain in women during the second and third trimesters of pregnancy. Therefore, prenatal exercise can be recommended as a safe, simple, and beneficial non-pharmacological intervention in midwifery care. It is expected that this study provides scientific evidence supporting the role of pregnancy exercise in improving maternal comfort and quality of life throughout pregnancy.

Diabetes mellitus is a chronic metabolic disease characterized by elevated blood glucose levels due to impaired insulin secretion or function. The prevalence of diabetes continues to increase in Indonesia, particularly among adults and the elderly, requiring comprehensive and sustainable management. Diabetes management is not limited to pharmacological therapy but also includes non-pharmacological approaches such as dietary management, physical activity, and health education. One form of physical activity recommended for diabetes sufferers is diabetes exercise. This study aims to determine the effect of diabetes exercise on reducing blood glucose levels in diabetes mellitus patients enrolled in the Chronic Disease Management Program (Prolanis) at the Gunungpati Community Health Center (Puskesmas). The study used a quantitative approach with a one-group pretest-posttest pre-experimental design. A total of 30 respondents were randomly selected from the Prolanis patient population, and blood glucose levels were measured before and after the diabetes exercise intervention. The intervention was carried out routinely and structured over a certain period. The analysis using the Wilcoxon Signed Ranks test showed a statistically significant decrease in blood glucose levels after diabetes exercise, with a p-value of 0.000 (p < 0.05). The average blood glucose level decreased from 260.27 mg/dL to 211.33 mg/dL. This study concluded that diabetes exercise is effective as a non-pharmacological intervention in helping control blood glucose levels. Therefore, routine implementation of diabetes exercise in primary healthcare facilities needs to be promoted as a simple, effective, and affordable promotive and preventive strategy.  

Diabetes mellitus continues to be an alarming health challenge, especially in the context of public health, where there are so many cases of diabetes mellitus that patients do not know how to manage and prevent it.

Food security is a fundamental aspect of independent and sustainable village development. Kajarharjo Village has abundant natural resource potential, such as cassava and various herbal plants. However, the utilization of this potential is still less than optimal, both in terms of food processing and the implementation of environmentally friendly agriculture. This condition encourages the need for community service activities oriented towards food innovation and strengthening sustainable agriculture. This service activity was carried out using a participatory and applied approach at the Kajarharjo Village Hall. The main target is the village community, especially housewives and farmers. The program is implemented through two main activities, namely: (1) training in making cassava leaf nuggets as a nutritious food, an alternative local product, and a household business opportunity; and (2) training in making organic boosters from natural ingredients as a more environmentally friendly substitute for chemical fertilizers. Implementation methods include counseling, demonstrations, direct practice, and interactive discussions to ensure active community involvement. The results of the activities show an increase in community knowledge and skills. Housewives are able to process cassava leaves into products with nutritional and economic value, while farmers gain skills in mixing organic boosters that can improve soil quality and agricultural yields without relying on chemical fertilizers. The participants' enthusiasm was also evident in their active participation in the practical exercises and their desire to apply the knowledge gained in their daily activities. In conclusion, this activity successfully encouraged the utilization of local potential in Kajarharjo Village through food innovation and organic farming. Empowering the community through cassava leaf processing and organic fertilizer production not only strengthens food security but also opens up business opportunities, maintains environmental health, and supports the development of an independent, healthy, and sustainable village.

Preoperative anxiety is common among women scheduled for cesarean section (C-section), affecting surgical outcomes, recovery, and bonding. This study investigated the effect of guided deep breathing relaxation on reducing preoperative anxiety in C-section patients. A quasi-experimental design with a pretest-posttest control group was conducted with 30 participants from [Name of Hospital]. Participants were randomly assigned to an intervention group (n = 15), which practiced deep breathing exercises 30 minutes before surgery, and a control group (n = 15) receiving standard care. Preoperative anxiety was assessed using the State-Trait Anxiety Inventory (STAI) before and after the intervention. Results showed a significant decrease in anxiety scores in the intervention group (from 45.2 ± 6.3 to 33.5 ± 5.8, p < 0.001), while the control group showed minimal change (44.8 ± 5.9 to 43.6 ± 6.1, p = 0.124). Post-intervention comparisons revealed a significant difference between groups (t = 7.21, p < 0.001). These findings indicate that guided deep breathing effectively reduces preoperative anxiety in C-section patients, suggesting it as a simple, safe, and cost-effective intervention that can improve maternal psychological well-being and surgical readiness. This non-pharmacological approach may also contribute to better postoperative outcomes.

Corruption is an extraordinary crime that not only causes massive state financial losses but also impedes national development. Efforts to eradicate corruption are insufficient if limited to the imprisonment of perpetrators; they must be accompanied by state asset recovery. The prosecutor, as the dominus litis in the criminal justice sistem, plays a central role in the process of seizing assets derived from corruption. This research aims to analyze the authority of prosecutors to seize assets in corruption cases, identify the obstacles encountered, and formulate solutions to optimize the exercise of this authority. The research method employed is normative juridical, utilizing a statutory approach and a case approach. The findings indicate that prosecutors have a strong legal basis for asset seizure, as stipulated in the Criminal Procedure Code (KUHAP), the Anti-Corruption Law, and other relevant regulations. However, in practice, prosecutors face various obstacles, both juridical, such as legal loopholes in the evidentiary process, and non-juridical, such as the complex modus operandi of perpetrators in concealing assets, slow inter-agency coordination, and challenges in tracing assets located abroad. Therefore, it is imperative to strengthen the regulatory framework through the enactment of the Asset Forfeiture Bill, enhance the capacity and integrity of prosecutors, and bolster international cooperation to maximize the recovery of state losses.

Adolescence is a crucial developmental phase marked by physical, emotional, and social changes, alongside new challenges brought about by the digital age. These changes often contribute to heightened stress and anxiety, particularly in academic settings. School, with its rigorous demands and social pressures, serves as a significant stressor. This community service project aimed to enhance the knowledge and practice of mindfulness among 10th-grade students at SMAN 3 Bone, specifically focusing on helping them cope with psychological and social pressures. Conducted on August 22, 2025, the project involved 33 female students navigating the transitional period of adolescence. The intervention consisted of an initial survey to assess baseline knowledge, followed by educational sessions on mindfulness theory and practical exercises, as well as group discussions and reflections. The results demonstrated a significant increase in students' mindfulness knowledge and skills, with the final average score reaching 80. Evaluation was based on observations throughout the activity and post-intervention assessments. The outcomes suggest that mindfulness education is an effective strategy for improving students’ ability to manage stress and anxiety. Despite the positive impact, challenges related to the implementation of mindfulness education within the school setting were identified, including the need for more structured integration into the curriculum and continuous support. Nevertheless, the findings highlight the potential of mindfulness practices as a valuable tool for supporting students' psychological well-being during adolescence, providing them with coping mechanisms for the pressures they face. Future recommendations include expanding the program to a broader student population and offering more regular mindfulness sessions to foster long-term benefits

Myofascial pain syndrome (MPS) is a condition characterized by muscle or fascia pain, involving sensory, motor, or autonomic functions, linked to myofascial trigger points (MTrPs). Motor symptoms can include muscle weakness, limited movement, and stiffness. Sensory symptoms may involve tenderness, referred pain, hyperalgesia, or allodynia, while autonomic symptoms include sweating, changes in skin temperature, and salivation. MPS occurs due to increased sympathetic nervous system activity, which worsens pain. Physical therapy is vital in improving movement and function, with Active Exercise Therapy being a recommended treatment. MPS affects 36% of 431 patients, with pain intensity often developing within a week, and in Indonesia, it reaches 40% within a year. MPS is more common in females than males. Active Exercise Therapy, which can be performed at home or work, is essential for preventing MPS. On July 31, 2025, a community service activity was held at RT VIII Tanjung Mas Village, Semarang Utara, with 29 participants. The event included blood pressure checks, blood sugar tests, BMI measurements, and counseling on the importance of exercise therapy to prevent muscle fatigue, particularly in the neck area. The therapy, focusing on improving tendon and ligament strength and muscle strength, helps maintain joint stability and increase the range of motion. Strength training includes isotonic exercises and progressive resistance training, tailored to each individual's needs. The event provided education on managing muscle pain and fatigue through targeted exercise routines and home programs. These initiatives emphasize muscle recovery, physical health, and overall wellness, ensuring participants can manage and prevent MPS effectively. The event highlighted the critical role of regular physical activity in improving quality of life and preventing long-term musculoskeletal pain.

Chronic kidney disease (CKD) that is left untreated can lead to serious complications, one of which is hypertension in hemodialysis patients. Intradialytic hypertension can impair quality of life and increase mortality risk. Benson relaxation therapy, which combines breathing techniques with the repetition of positive words, has the potential to lower blood pressure. The purpose of this research is to measured blood pressure during and subsequent to Benson relaxation therapy in hemodialysis patients. This quantitative research employed a pre-experimental methodological approach with a case study approach. The subjects consisted of 3 respondents selected from a population of 24 hemodialysis patients at a hospital. Blood pressure data were collected using a digital sphygmomanometer and analyzed descriptively. After three sessions of Benson relaxation therapy lasting approximately 10 minutes each, systolic blood pressure decreased with the maximum reduction of 18 mmHg and the lowest reduction of 2 mmHg, while diastolic blood pressure decreased with the maximum reduction of 20 mmHg and the lowest reduction of 1 mmHg. Benson relaxation therapy can reduce blood pressure in patients undergoing hemodialysis. Benson relaxation therapy may be considered as a non-pharmacological intervention to help lower blood pressure in hemodialysis patients. After three sessions of Benson relaxation therapy lasting approximately 10 minutes each, systolic blood pressure decreased with the maximum reduction of 18 mmHg and the lowest reduction of 2 mmHg, while diastolic blood pressure decreased with the maximum reduction of 20 mmHg and the lowest reduction of 1 mmHg. These results indicate that Benson relaxation therapy can significantly reduce blood pressure in hemodialysis patients. The therapy’s effectiveness in reducing blood pressure may be attributed to the deep breathing exercises and the relaxation response it induces, which helps to reduce the overall stress on the cardiovascular system.
