Prosthetisation of a K2 Patient with Sub-ischial Socket Compared to Ischial Containment (IC) Socket: A Case Report

Davide Buratti, Matteo Vaccari — Sat, 31 May 2025 00:00:00 +0700

Background: Ischial Containment Socket (ICS) has been the standard treatment for transfemoral amputees for
thirty years, but the high edges and the ischial containment contribute to the discomfort of the socket especially
when the patient is standing and while he is sitting.
Aims: The purpose of this study is to compare ICS to sub-ischial socket in a unilateral TFA K2 patient.
Methods: Two custom-fabricated sockets, worn full-time for 3 weeks, with testing on day 0 and at 3 weeks after
socket delivery. The case report examined a 71-year-old woman three years after one-sided transfemoral
amputation to the right leg, with K2 functional level. The protocol used contained three questionnaires, the
measurement of the hip range of motion and 2 physical tests.
Results: The most relevant results were the reduction of the pelvic inclination during the sitting with a variation
of -42.9% (7° with the ICS and 4° with the sub-ischial socket), and an increase in all the measurements of the
angles of the hip, especially in abduction and extension with percentage change that reaches +300% each. The
two sockets were equivalent in the 2MWT (P-value=0.98) and in the 4SST (P-value=0.88) (statistical significance
p<0.05). The patient reported that the sub-ischiatic socket is more comfortable and has more freedom of
movement.
Conclusion: It can be said that for patient K2 examined, the sub-ischial socket is a valid clinical alternative to the
one with ischial containment, since it does not affect aspects such as stability and dynamics, but it also offers
improvements in the stump-socket interface.

Deby Eka Supadma, Rina Fitriana Rahmawati, Jusuf Kristianto — Sat, 31 May 2025 00:00:00 +0700

Background: A transtibial prosthesis restores mobility and functionality for individuals with below-knee amputations, with the socket serving as a vital interface between the residual limb and the prosthesis. In Indonesia, prosthetic sockets are commonly made from plastic, valued for strength and durability but criticized for non-sustainability, and high import costs. Locally sourced and cost-effective materials, such as pineapple leaf fiber, have gained attention as sustainable alternatives, offering lightweight and durable solutions. However, the natural fiber’s appearance may impact amputee satisfaction. Combining pineapple leaf fibers with polyester fabric could address these limitations by improving aesthetics without compromising functionality.
Aims: This study aimed to develop and evaluate a transtibial prosthetic socket fabricated from pineapple leaf fibers and polyester fabric, focusing on accessibility, affordability, and enhanced usability for Indonesian amputees.
Methods: The study used a quantitative experimental design that included creating composite materials with specific ratios of pineapple leaf fiber, epoxy resin, and polyester fabrics and fabricating transtibial prosthetic sockets using the lamination method. The socket was fitted to a transtibial amputee to ensure proper alignment and function. Over six weeks, the participant used the prosthesis in daily activities while data was collected on comfort, durability, and walking performance, along with feedback through interviews and questionnaires.
Results: Amputee demonstrated improved mobility in daily activities, with slight endurance limitations during extended walking. Satisfaction was high regarding comfort, fit, aesthetics, and reliability.
Conclusion: The composite material is a viable alternative for transtibial sockets, promoting sustainability and accessibility. Refinements for endurance and broader applications of natural fibers are recommended.

Background: Over time, various problems have emerged alongside societal developments, including those in the health sector. One common issue is musculoskeletal disorders, particularly low back pain (LBP). Nonspecific Low Back Pain (NSLBP) refers to a pain syndrome in the lower back region without a clearly identifiable cause. Spinal orthosis has been proposed as a potential treatment for back pain.
Aims: This study aims to examine the effectiveness of spinal orthosis in managing low back pain through a literature review.
Methods and Subjects: A literature review was conducted using databases such as Google Scholar, PubMed, and ScienceDirect. The keywords used included "spinal orthosis," "lumbar corset," and "low back pain." Only full-text English articles with an experimental design were included. Article selection followed the PRISMA diagram guidelines.
Results: Low back pain can affect individuals of all ages, including adolescents and adults. Pain assessment tools such as the Visual Analog Scale (VAS) and Numeric Rating Scale (NRS) were commonly used in the studies. Among the types of spinal orthoses, Lumbosacral Orthosis (LSO) was found to be effective in reducing pain in individuals with low back pain.
Conclusion: The use of a spinal orthosis, particularly a lumbosacral orthosis, in daily activities contributes to pain reduction in individuals suffering from nonspecific low back pain.

The Influence of Calf Support on Leg Power in Non-Athlete Badminton Players

Atika Febri Anggriani, Hisyam Syafi’ie, Lafi Graita — Sat, 31 May 2025 00:00:00 +0700

Background: Badminton players require strong lower-leg muscle strength (leg power) to execute effective
footwork and hitting techniques. Leg power can be enhanced through exercises like calf raises and the use of calf
support. Calf support, made of elastic material, applies pressure and warmth to the calf, promoting blood flow
and muscle oscillation, which may improve muscle compression and performance.
Aim: This study investigates the effect of calf support on leg power in badminton players.
Methods: A quasi-experimental design was employed, with a population of 30 players and a final sample of 25
selected via purposive sampling based on inclusion/exclusion criteria. Leg power was assessed using a vertical
jump test, followed by a 150-minute calf support intervention during gameplay. Data normality was checked using
the Shapiro-Wilk test, and statistical analysis was performed with a Paired Sample T-test.
Results: The analysis revealed a significant increase in leg power (p = 0.000) with calf support, showing an average
difference of 46.24 (a 22% improvement). This indicates that calf support significantly enhances lower-leg muscle
strength in badminton players.
Conclusion: Calf support significantly improves leg power in badminton players, suggesting its potential as a
performance aid.

Sea Pandan Leaf Fiber as an Alternative Material for Upper Limb Orthosis

Sat, 31 May 2025 00:00:00 +0700

Background: The use of natural materials as an alternative to reduce the use of chemicals. One of the steps is the utilization of natural fibers from sea pandan leaves as a substitute for fiberglass chemicals in the process of making assistive devices for upper limb deformities.
Objective: The objective of this scientific work is to utilize synthetic fiber alternatives used in the production of upper limb orthoses.
Method: The data collection method used by the researcher is by tracing primary data: observing the composite results of sea pandan leaf fibers.
Results: The experimental results show that fibers from sea pandan leaves soaked in a solution of 6 grams of NaOH and 3000 ml of water for one hour, then dried for 24 hours, can be used as a reinforcing material. By using 342.72 ml of resin and 6.8 ml of catalyst, these sea pandan fibers can optimally absorb the resin, thereby forming a sturdy composite structure through the thermal hardening process. The final product produced is a Wrist-Hand Orthosis (WHO) designed to address cases of Carpal Tunnel Syndrome (CTS). This orthosis demonstrates good shape and rigidity, although it is not as strong as fiberglass. The main advantage of sea pandanus fiber is its environmentally friendly properties and natural origin.
Conclusion: Sea pandan leaf fibers are a promising alternative to replace fiberglass in WHO production in CTS cases. The process of soaking the fibers in NaOH solution has been proven to enhance resin absorption and strengthen the material's strength. The research results show that this natural fiber has the ability to provide good strength and stiffness, while remaining an environmentally friendly option and supporting the sustainable use of local natural resources.
