Effect of Soft Knee Brace on Shank Movement in Running

Kodai Kitagawa — 2024-11-01

Background: Soft knee braces are used for the protection and treatment of knee injuries in light-intensity activities of daily life. Soft knee braces have several functions, such as stabilizing and supporting the lower limb posture. However, previous studies did not investigate the effects of a soft knee brace on the lower limbs during vigorous-intensity activities.

Aims: The objective of this study was to investigate the effect of a soft knee brace on the physical load and stability of the lower limb during running as a vigorous-intensity activity.

Methods: Participants were asked to run with or without a soft knee brace, and lower-limb movements during running were measured using an inertial sensor on the shank.

Results: The result showed that soft knee brace significantly reduced the magnitude and mediolateral standard deviation of shank acceleration.

Conclusion: The results of this study indicate the possibility that wearing a soft knee brace can improve the physical load and stability of the lower limbs during running.

Background: Poliomyelitis is a highly infectious viral disease often causing permanent paralysis. Post-Polio Paralysis (PPP) involves the delayed onset of new or worsening neuromuscular symptoms years after the initial attack. Polio survivors face numerous physical disabilities and significant social, financial, and human rights barriers.

Aims: To identify the challenges faced by individuals with PPP in the Khyber Pakhtunkhwa region.

Methods: The study employed a cross-sectional survey design with a sample size of n=200, selected through non-probability convenience sampling. Data were collected using the Post-Polio Clinic Questionnaire and analyzed with SPSS 22.

Results: The gender distribution was 21.50% female and 78.50% male. New health and physical problems (neurological, arthritis, and physiological) were observed in 64.5% (n=129) of participants. Aggravated previous complications, such as pain, fatigue, and muscular atrophy, were reported by 91.5% (n=183). Difficulty performing heavy tasks was noted by 49.5% (n=99). Using public transport was a challenge for 46.5% (n=93), and driving a car was deemed impossible by 70% (n=140). Using an Indian commode as a toilet was a complication for 58% (n=116) of participants.

Conclusion: The study reveals significant health and daily life challenges for polio survivors in Khyber Pakhtunkhwa, including a high prevalence of new and worsening neuromuscular symptoms, aggravated complications like pain and fatigue, and difficulties with heavy tasks, public transport, driving, and using certain toilets. These findings underscore the urgent need for targeted interventions to improve the quality of life for polio survivors by addressing their physical health and social and financial barriers.

Differences in Walking Speed of SACH Foot And Single Axis Foot in Transtibial Prosthesis User

Dody Suprayogi — 2024-11-01

Background: Lower limb amputation causes disruption of limb function, one of which is the ability to walk. One of the walking aids that can be used is a transtibial prosthesis. A transtibial prosthesis consists of a socket, shank and foot components. The choice of foot type and the use of a transtibial prosthesis is one of the factors that influence walking speed. SACH foot and single axis foot are the types of foot that are often used by prosthesis users

Aims: To determine the difference in walking speed of SACH Foot and Single Axis Foot in transtibial prosthesis users.

Method and Subjects: Using quantitative research, observational method with cross sectional design. The subjects of this research were users of transtibial prosthesis type SACH foot and single axis foot. The sample for this study consisted of 28 people. The measuring instruments used in this research are 10 MWT (Meter Walk Test).

Results: Based on statistical tests, the results showed that there were differences in walking speed between SACH foot and single axis foot type transtibial prosthesis users. Where the p value <0.05 is 0.000 with an effect size of 0.81, which means it has a high or strong difference effect.

Conclusion: There is a difference in walking speed, namely the walking speed of users of single axis foot transtibial prosthesis is faster than SACH foot. So, it is recommended to prefer using a single axis foot in users of transtibial prosthesis, especially at moderate activity levels. The limitations of this research are that there are not many subjects and the foot types are less diverse. Future research can be developed with other types of foot prosthesis and measurement of gait parameters

Impact of Custom Foot Orthosis on Dynamic Balance in Sports Enthusiasts with Flat Feet

Anastya Yuridha Bahrunnajah — 2024-11-01

Background: Custom foot orthoses (CFOs) have been extensively studied for their effectiveness in redistributing plantar pressure, aligning foot structure, and enhancing stability in individuals with flatfoot (Desmyttere et al., 2019; Xu et al., 2020). Flatfoot, characterized by reduced or absent arches, often leads to overpronation and compromised musculoskeletal alignment, impacting dynamic balance and elevating injury risk during physical activity (Hawke et al., 2015). This study examines the impact of CFOs on dynamic balance specifically in sports-active individuals with flatfoot, where optimal balance is critical due to rapid directional changes and stability demands. By providing customized support, CFOs may serve as a practical intervention to improve stability and support safe sports participation.

Methods: This quantitative, experimental study used a one-group pre-test and post-test design with purposive sampling. Twelve subjects participated, and dynamic balance was measured using the Modified Bass Dynamic Balance Test.

Results: Statistical analysis with a paired-sample t-test yielded a p-value of 0.002, indicating a significant positive effect of CFOs on dynamic balance (p < 0.005).

Conclusion: The findings indicate a positive effect of CFOs on dynamic balance in flatfoot individuals engaged in sports. It is recommended that individuals with flatfoot, particularly those involved in sports, consider CFOs to improve balance and reduce injury risk. Regular assessments by healthcare professionals may further optimize orthotic benefits for enhanced performance and stability.

The Relationship of Arcus Pedis Form with Running Speed in Markentho's Football Running Community at Manahan Stadium

Atika Febri Anggriani — 2024-11-01

Background: Running speed refers to a person's ability to perform consecutive movements to cover a distance in the shortest possible time. This speed is influenced by the arch of the foot (arcus pedis), which can be classified as low, high, or average, and functions as a shock absorber when the foot contacts the ground. Common deformities in abnormal foot structures include pes cavus and flat feet.

Aim: To determine the relationship between the condition of the arcus pedis and running speed in the Anak Buah Markentho running community at Manahan Stadium.

Methods: This research was conducted on 25 members of a running community. The normality test was performed using the Shapiro-Wilk test, and the hypothesis was tested using Spearman's correlation.

Results: The analysis yielded a significance value of 0.000 (p < 0.05), indicating a significant correlation between the shape of the arcus pedis and running speed. The Spearman correlation coefficient was 0.691, showing a positive and strong correlation.

Conclusion: Greater deviations in the arch shape are associated with lower running speed, demonstrating a significant and strong correlation. This suggests a clear relationship between the shape of the arcus pedis and running speed.

Impact of Silicone Arch Support on Energy Expenditure in Flexible Flatfeet Employees

Belva Lativa Putri Erwinsyah — 2024-11-01

Background: Flat feet, or pes planus, is a common condition affecting approximately 20-30% of the general population, leading to muscle tension and instability that can impact energy expenditure during walking.

Objective: To evaluate the effectiveness of Silicone Medial Arch Support in reducing energy expenditure during walking in individuals with flat feet compared to a control group.

Methods: A total of 32 participants with flexible flat feet were selected through random sampling. This study employed a quasi-experimental design with a control group using a sham insole and an intervention group using silicone medial arch support for two months. Energy expenditure was measured using VO? max. The average energy expenditure before using silicone medial arch support was 36.76 ± 5.03 ml/kg/min, which increased to 39.75 ± 4.05 ml/kg/min post-intervention (p < 0.001). For the sham insole group, the energy expenditure was 34.67 ± 2.44 ml/kg/min before and 34.87 ± 2.20 ml/kg/min after the intervention (p = 0.183).

Results: The use of silicone medial arch support resulted in a significant increase in energy expenditure compared to the sham insole group (p < 0.001).

Conclusion: The study concludes that silicone medial arch support can reduce energy expenditure during walking in individuals with flat feet. These results suggest that incorporating well-designed arch support interventions can significantly improve biomechanical efficiency and comfort for individuals with flat feet. Future interventions should consider individual variations in foot morphology and activity levels to optimize support design, potentially integrating adjustable or customizable insoles to better address the diverse needs of this population.
