This is due to the closed environment of the socket, which disrupts the body&#39;s natural cooling mechanisms and can lead to increased skin temperature, sweating, and various skin problems. This study aimed to develop a new socket to alleviate heat buildup in those with below-knee amputation.</span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Methods: </b>A positive residual limb model of a below-knee amputee was used to create a new socket made of copper metal through electroforming. A cooling system was programmed so that if the temperature exceeded a predetermined threshold, the system would be activated to prevent further temperature increase. The participant wore the conventional and new socket with the cooling system, and his residual limb skin temperature was monitored using a temperature data logger.</span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Results:</b> Implementing the new socket led to a significant 5&deg;C to 6&deg;C reduction in temperature within the socket, greatly enhancing thermal comfort and reducing heat sensation for the users. </span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Conclusion:</b> By incorporating the new socket and cooling system, substantial reductions in heat accumulation within the prosthetic socket can be achieved.</span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal"></span></span></span></span></span></span></span></span><br> &nbsp; Prosthetic socket, Temperature, Below-knee amputation, Electroforming, Active Cooling System, Heat Reduction 659 666 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-4450-3&slc_lang=en&sid=1 Mahboobeh Farhoudi mahboobefarhoudi@gmail.com 200319475328460089489 0009-0003-3877-7288 No Department of Orthotics and Prosthetics, School of Rehabilitation Sciences, Iran University of Medical Sciences, Tehran, Iran Behnam Hajiaghaei hajiaghaei.b@iums.ac.ir 200319475328460089490 200319475328460089490 Yes Department of Orthotics and Prosthetics, School of Rehabilitation Sciences, Iran University of Medical Sciences, Tehran, Iran Hassan Saeedi hassan_saeedi2@yahoo.co.uk 200319475328460089491 200319475328460089491 No Department of Orthotics and Prosthetics, School of Rehabilitation Sciences, Iran University of Medical Sciences, Tehran, Iran Taher Babaee taher.to3@gmail.com 200319475328460089492 200319475328460089492 No Department of Orthotics and Prosthetics, School of Rehabilitation Sciences, Iran University of Medical Sciences, Tehran, Iran
