Korean-PEQ (prosthesis evaluation questionnaire) was developed and verified its validity research but, evaluating its reliability applied to the lower extremity amputees have not been conducted. The aim of this study was to apply the Korean-PEQ for lower extremity amputees to evaluate the reliability. As a result, all of the items responding of Korean-PEQ shown to less than 15% ceiling effect and floor effect. therefore, the results were shown to be appropriate. Korean-PEQ reliability of each region of intra-class coefficient was shown to .719(95% CI .600~.811)~920(95%CI .890~.945) and the inter-region reliability was higher as 0.958. Item internal consistency Cronbach's ${\alpha}$ values are shown as higher .910.

Purpose: This study verifies the muscle activity around the amputation site during proprioceptive neuromuscular facilitation (PNF) pattern exercise for the upper extremities on the non-amputated part in upper extremity amputees and provides basic data on effective exercise around an amputation site. Methods: Manual resistance was applied to the PNF upper extremity pattern of the non-amputated part to generate muscle activity around the amputation site. The resistance was adjusted to an intensity that could cause maximal isometric contraction. The muscle activity of the amputation site and the non-amputated part was measured using a surface electromyogram for the upper trapezius, middle trapezius, infraspinatus, serratus anterior, and pectoralis major. Results: During the scapular exercise in the painless range, the amputated side showed significantly lower muscle activity and a lower muscle contraction ratio compared with the non-amputated side. During the PNF pattern exercise in the painless range, the amputated side showed lower muscle activity and a lower muscle contraction ratio compared with the non-amputated side. When the direct scapular exercise of the amputated side was compared with the PNF pattern exercise of the non-amputated side, their muscle contraction ratios were similar. Conclusion: This study confirmed the effectiveness of the PNF pattern exercise of the non-amputated part as a way to indirectly train the injured site with no pain for rehabilitation of patients with serious body injuries, such as amputation. It is necessary to develop effective exercise programs for the rehabilitation of the amputation site based on the results of this study.

Purpose: This study aimed to investigate the effect of an intensively rehabilitation program on the gait, balance, functional performance, and wearing satisfaction of patients with traumatic lower extremity amputations caused by industrial accidents. Methods: In this study, the anonymized electronic medical records of individuals who participated in the intensive rehabilitation program (among those who were admitted to the hospital belonging to the Labor Welfare Corporation) due to an industrial accident from August 2018 to September 2019 were collected. As a result, the records of 12 subjects meeting the screening criteria were analyzed. Results: According to the time of application to the intensive rehabilitation program, the 10 Meter Walk Test (10MWT) (p < 0.01), Berg Balance Scale (BBS) (p < 0.01), Timed Up and Go Test (TUG) (p = 0.01), the L Test of Functional Mobility (L-test) (p < 0.01), Prosthetic Limb Users Survey of Mobility (Plus-M) (p < 0.01), and Houghton Score Question (HSQ) (p < 0.01) values significantly improved with time. Conclusion: This study confirmed the positive effect of an intensive rehabilitation program on the gait, balance, functional performance, and wearing satisfaction of patients with traumatic lower extremity amputations caused by industrial accidents. However, this study was limited by the absence of a control group, and, thus, it highlights the need for more extensive research with a large sample.
