Abstract

Background: Flat foot is the most prevalent musculoskeletal condition. Research indicates that between 20 and 30 % of youngsters worldwide suffer from flat feet. In addition to being a static alignment issue of the ankle and foot, flat foot is progressive and can contribute to aberrant dynamic function of other lower limbs. This condition directly affected the degree of q angle. The purpose of this study was to compare the degree of q angel knee joint, before and after the use of custom foot othosis in the study sample Methods: This is a quasi-experimental study with one group pre and post test design to determine the effect of using custom foot orthoses on reducing the degree of Q angle in flat foot. The total number of research samples is 26. The Wilcoxon test was used in this study to analyze the impact of the orthosi. Results: Based on the results of wilcoxon tests show that the p value is < 0.001 (p-value < 0.05), there was a significant difference in the use of custom foot orthoses before the intervention and after the intervention by 5.80. As a result. There was a significant difference in the use of custom foot orthoses before the intervention and after the intervention in reducing the degree of Q angle knee joint. Conclusion: The use of custom foot orthoses can significantly reduce the degree of Q angle knee joint of the study subjects. It is recommended to use orthosis to improve the degree of the Q angle.

Abstract

Background: Basketball is popular in Indonesia, and vertical jump ability plays a significant role in performance in the game. Abnormal curvature of the legs can reduce jump outcomes. The use of custom foot orthoses can help address this condition. This study aims to determine the effect of custom foot orthoses on vertical jumps in flat-footed basketball players.  Methods: This study used a one-group pretest-posttest design with a population of 25 people and 23 respondents selected through purposive sampling. The vertical jump was evaluated using a vertical jump test conducted before and after one month of using foot orthoses. Data were analyzed using a Paired Sample T-test.  Results: The results of the statistical test showed a p value of <0.001 (p < 0.05), indicating a significant difference in the use of custom foot orthosis before and after the intervention.  Conclusion: There is an improvement in the vertical jump of basketball players with flat foot condition.  Custom foot orthoses are recommended for use to improve the vertical jump of basketball players with flatfoot conditions.

Abstract

Background: Osteoarthritis of the knee is a degenerative joint disease that often causes pain, activity limitations, and balance disorders, particularly dynamic balance. One conservative approach to reducing symptoms and improving knee joint stability is the use of neoprene knee brace with hinges to provide compression and lateral-medial support, as well as enhance proprioception and neuromuscular control, all contributing to improved dynamic balance. Aims: To determine whether there is an effect of using a neoprene knee brace with hinge on dynamic balance in patients with knee osteoarthritis. Methods: This research method is quasi-experimental with a one-group pre-test and post-test design. The research sample consisted of 18 women aged 45-60 years who were selected using purposive sampling techniques based on inclusion and exclusion criteria. This study used the Time Up and Go Test to measure dynamic balance. Data normality was checked using the Shapiro-Wilk test, and statistical analysis was performed with a Paired Sample T-test. Results: Data analysis using a paired sample t-test showed a p-value of 0.000, indicating a significant difference between the pre-test and post-test scores. The average TUG test time before brace use was 16.60 seconds and after the intervention was 10.06 seconds, a difference of 6.54 seconds. Conclusion: The use of a neoprene knee brace with hinge has a significant effect on improving dynamic balance in patients with knee osteoarthritis, and can be an effective non-surgical intervention option in conservative treatment.

Abstract

Pes planus (flat foot) is a condition characterized by the loss of the medial longitudinal arch of the foot, which can alter lower extremity biomechanics, including an increased Q-angle of the knee joint that may lead to functional knee disorders. This problem is commonly found among individuals with sports activities; however, knowledge regarding the management using flexible medial arch support remains limited. In order to decrease the Q-angle of the knee joint, this community service program aimed to increase the knowledge and abilities of people with flat feet in the use of flexible medial arch support. An initial survey, instructional sessions on flat foot, Q-angle of the knee joint, and flexible medial arch support, practical training on the device's usage, monitoring, and program assessment were among the implementation strategies. Over the course of a year, the program was carried out in phases, including administrative planning, coordination, instruction, hands-on support, and final assessment. The results indicated an increase in participants’ knowledge regarding the use of flexible medial arch support and their ability to apply the device independently. Furthermore, this activity contributed to improving community understanding of the role of orthotics and prosthetics in managing lower extremity disorders. An additional output in the form of educational video documentation was also produced to support broader information dissemination to the community.

Abstract

Background: Transtibial amputations generally have a better survival prognosis, and the remaining stump length after transtibial amputation (ideally 12-35 cm) plays a crucial role in the functional mobility of prosthesis users, including balance, weight transfer, walking, and daily activities. Mobility limitations can negatively impact the social aspects, quality of life, and health of amputees, making restoring mobility through prosthesis use an important goal. The purpose of this study was to determine and prove to evaluate the contribution of stump length the relationship between stump length and functional mobility in transtibial prosthesis users.   Methods: The research method used was quantitative, with an analytical observational study and a cross-sectional design. A total of 15 respondents were selected from a population of 55 below-knee amputee patients using transtibial prostheses using a purposive sampling technique using the L – Test of Functional Mobility instrument.   Results: The Spearman Rank Correlation test produced a p-value of <0.001 which is statistically significant with a correlation coefficient of 0.845 which is very strong and positive. So, there is a very strong relationship between stump length and functional mobility in transtibial prosthesis users.   Conclusion: The longer the transtibial stump, the better the functional mobility. It is recommended that during amputation the stump be kept as long as possible.
