ABSTRACT
ObjectiveTo explore the efficacy of high-frequency repetitive transcranial magnetic stimulation (rTMS) in M1 region combined with dorsolateral prefrontal cortex (DLPFC) on electroencephalogram (EEG) θ frequency band amplitude of patients with neuropathic pain (NP) after spinal cord injury. MethodsFrom June, 2022 to June, 2023, 50 NP patients after SCI in Qingdao University Affiliated Hospital were included and divided into M1 region stimulation group (n = 25) and M1 region combined with DLPFC stimulation group (the combined stimulation group, n = 25). M1 region stimulation group received 10 Hz rTMS in the left M1 region, while the combined stimulation group received same stimulation in left M1 region combined with DLPFC, for three weeks. Before and after intervention, the pain was assessed with Short Form of McGill Pain Questionnaire (SF-MPQ), the depression and anxiety status were evaluated using Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA), and the EEG θ frequency band amplitude was recorded to detect the changes of brain electrophysiological activity. ResultsFour cases in M1 region stimulation group, and two cases in the combined stimulation group were dropped. After intervention, the total score of SF-MPQ and the scores of the subscales, the scores of HMMD and HAMA decreased in both groups (|t| > 2.523, P < 0.05). The EEG θ frequency band amplitude significantly reduced in the prefrontal and frontal regions in M1 region stimulation group (|t| > 5.243, P < 0.001), and it also significantly reduced in the prefrontal, frontal regions, central and parietal regions in the combined stimulation group (|t| > 4.630, P < 0.001). All the scores were lower (|t| > 2.270, Z = -1.973, P < 0.05), and the EEG θ frequency band amplitude in the prefrontal, frontal regions, central and parietal regions were lower (P < 0.05) in the combined stimulation group than in M1 region stimulation group. ConclusionHigh frequency rTMS is an effective analgesic method on NP after SCI, which can improve their depression and anxiety symptoms and reduce the EEG θ frequency band amplitude. Compared with M1 region rTMS stimulation, the combination of M1 region and DLPFC rTMS is more effective.
ABSTRACT
@#Introduction: This systematic review aimed to investigate the level of participation, obstacles, and facilitator factors that influence activities of daily living among persons with spinal cord injury (SCI). Methods: A comprehensive search was conducted in four online databases, namely Google Scholar, PubMed, OT Seeker, and Cochrane Library covering the ten-years period from January 2012 to December 2022. Inclusion criteria encompassed original published studies in English focusing on daily activities, work, participation, obstacles, and facilitators in persons with SCI. Non-peer review sources (e.g., abstracts, grey literature, preprints), and studies unrelated to occupational therapy were excluded. The selected studies were assessed for quality using McMaster University Occupational Therapy Evidence-Based Practice critical review form. Results: Out of the 678 articles identified, ten studies were included after the screening, exploring participation in daily living activities, employment, return to work, leisure activities, family tasks, and community mobility among persons with SCI. Obstacles and facilitators influencing participation in activities of daily living were classified using the International Classification of Functioning, Disability, and Health (ICF) framework. This review highlighted that long-term participation is challenging for persons with SCI, affected by obstacles such as body functions, pain, low self-esteem, and environmental and social factors. Conclusion: The findings underscore the importance of adopting a multidisciplinary rehabilitation approach to enhance participation in daily activities for persons with SCI. Occupational therapy plays a significant role in improving participation levels among persons with SCI.
ABSTRACT
ObjectiveTo observe the clinical efficacy of modified Shenqi Pill （肾气丸） plus Tongdu Tiaoshen Acupuncture （通督调神针刺） in the treatment of neurogenic bladder after spinal cord injury of kidney-yang deficiency syndrome. MethodsForty-six patients were randomly divided into 23 cases each in the control group and the treatment group. Both groups were given conventional treatment， i.e. oral methylcobalamin tablets （0.5 mg each time， 3 times a day） and paraplegic conventional acupuncture （once a day， 6 consecutive days a week）. The control group was given simple bladder function rehabilitation training on the basis of the conventional treatment； and the treatment group was given modified Shenqi Pill orally （1 dose a day， 150 ml each time， taken warmly in morning and evening） and Tongdu Tiaoshen Acupuncture （once a day， 6 consecutive days per week） in addition to what were given to the control group. The treatment course lasted for 4 weeks. The 24 h urination frequency， 24 h urine leakage frequency， 24 h single urine volume， bladder residual urine volume， international lower urinary tract symptom （LUTS） score， traditional Chinese medicine （TCM） syndrome score were compared between the two groups， and clinical effectiveness and TCM syndrome effectiveness were compared between the two groups after treatment. ResultsTwenty patients in each group were finally analyzed in this study. The number of 24 h urination， the number of 24 h urine leakage， bladder residual urine volume， LUTS score， and the TCM syndrome scores decreased after treatment in both groups， and the 24 h single urine volume increased （P＜0.01）； and much more improvement was found of each index in the treatment group than in the control group （P＜0.05 or P＜0.01）. The total clinical effectiveness and TCM syndrome effectiveness in the treatment group was 85.00% （17/20） respectively， which were statistically significantly higher than 45.00% （the total clinical effectiveness， 9/20） and 60.00% （TCM syndrome effectiveness， 12/20） in the control group （P＜0.01）. ConclusionModified Shenqi Pill plus Tongdu Tiaoshen Acupuncture can signi-ficantly improve the clinical symptoms of neurogenic bladder patients after spinal cord injury of kidney-yang deficiency syndrome， having better effectiveness than simple bladder function rehabilitation training， and its mechanism may be related to the improvement of the injured nerve function innervating the bladder.
ABSTRACT
OBJECTIVE@#To explore the effect of shikonin on the recovery of nerve function after acute spinal cord injury(SCI) in rats.@*METHODS@#96 male Sprague-Dawley(SD)rats were divided into 4 groups randomly:sham operation group (Group A), sham operation+shikonin group (Group B), SCI+ DMSO(Group C), SCI+shikonin group (Group D).The acute SCI model of rats was made by clamp method in groups C and D . After subdural catheterization, no drug was given in group A. rats in groups B and D were injected with 100 mg·kg-1 of shikonin through catheter 30 min after modeling, and rats in group C were given with the same amount of DMSO, once a day until the time point of collection tissue. Basso-Beattie-Bresnahan(BBB) scores were performed on 8 rats in each group at 6, 12, and 3 d after moneling, and oblique plate tests were performed on 1, 3, 7 and 14 d after modeling, and then spinal cord tissues were collected. Eight rats were intraperitoneally injected with propidine iodide(PI) 1 h before sacrificed to detection PI positive cells at 24 h in each group. Eight rats were sacrificed in each group at 24 h after modeling, the spinal cord injury was observed by HE staining.The Nissl staining was used to observe survivor number of nerve cells. Western-blot technique was used to detect the expression levels of Bcl-2 protein and apoptosis related protein RIPK1.@*RESULTS@#After modeling, BBB scores were normal in group A and B, but in group C and D were significantly higher than those in group A and B. And the scores in group D were higher than those in group C in each time point (P<0.05). At 12 h after modeling, the PI red stained cells in group D were significantly reduced compared with that in group C, and the disintegration of neurons was alleviated(P<0.05). HE and Nissl staining showed nerve cells with normal morphology in group A and B at 24h after operation. The degree of SCI and the number of neuronal survival in group D were better than those in group C, the difference was statistically significant at 24h (P<0.05). The expression of Bcl-2 and RIPK1 proteins was very low in group A and B;The expression of RIPK1 was significantly increased in Group C and decreased in Group D, with a statistically significant difference (P<0.05);The expression of Bcl-2 protein in group D was significantly higher than that in group C (P<0.05).@*CONCLUSION@#Shikonin can alleviate the pathological changes after acute SCI in rats, improve the behavioral score, and promote the recovery of spinal nerve function. The specific mechanism may be related to the inhibition of TNFR/RIPK1 signaling pathway mediated necrotic apoptosis.

ABSTRACT
Objectives: Inactivity in individuals with spinal cord injury (SCI) results in low physical fitness, cardiopulmonary endurance and poor quality of life. Sports participation is known to enhance physical fitness. Therefore, the present study evaluated effect of a structured, 12-week MGM Sports Intervention for Sports Intervention Program for SCI (SPISI) on physical fitness and throw-ball performance in individuals with SCI. Materials and Methods: The study was conducted at MGM School of Physiotherapy and Spinal Cord Injury Rehabilitation centre in Navi Mumbai, India. Following ethical approval, 15 individuals with SCI (80% males and 20% females mean age 33.1 ± 7.2 years) were recruited. Upper-extremity explosive power (medicine-ball-throw), agility (t-test), cardiorespiratory endurance (incremental shuttle wheelchair propulsion test) and ball-throwing capacity (maximal-pass test) were evaluated pre- and post-12-week sports intervention programme (SPISI). The protocol involved strength training of upper extremity training at 50% 1 repetition maximum and participation in throw-ball sport. Results: Following training, increase in upper extremity explosive power (11%), cardiopulmonary endurance (5%), agility (8%) and ball-throwing capacity in distance (7%) (P < 0.05) was observed. The large effect size was observed for sports performance (maximal-pass test distance-Cohen’s d 1.261), moderate for cardiorespiratory endurance (incremental wheelchair propulsion test distance Cohen’s d 0.517) and upper extremity explosive power (medicine-ball throw distance 0.593). Increment in all outcome variables was greater than minimal clinically important difference. Conclusion: Sports intervention programme (SPISI) for 12 weeks brought about minimal clinically important difference in upper-extremity explosive power, agility, cardiorespiratory endurance and sport-specific performance and should be included as an integral component of rehabilitation of individuals with SCI.
ABSTRACT
Abstract Impediment to local anesthetic solution in the epidural space results in unsatisfactory pain relief during labor epidural. Patients with a history of back trauma and spinal instrumentation have increased rates of epidural failure due to patchy spread of local anesthetic with obliterated epidural space. Dual Epidural Catheters (DEC) can be used in such clinical scenarios with complete labor analgesia and improved patient satisfaction. We present the successful management of a parturient with vertebral fracture at risk for epidural failure and neurologic injury due to bone fragments and inserted cranial and caudal to the fractured vertebra using ultrasound to avoid neurologic sequelae.

Abstract Objective To evaluate the effects of exercise training on neurological recovery, Growth Transforming Factor-β1 (TGF-β1), Hypoxia Inducible Factor-1α (HIF-1α), and Nogo-NgR signaling pathways after spinal cord injury in rats. Methods Forty-eight male Sprague-Dawley rats were randomly divided into four groups: normal group, sham-operated group, model group, and training group. The rat spinal cord injury model was established using Allen's method, and the training group received exercise training on the 8th day postoperatively. The Basso, Beattie and Bresnahan (BBB) score, modified Tarlow score, and inclined plane test scores were compared in each group before injury and 1, 7, 14, 21 and 28 days after injury. Results The BBB score and modified Tarlow score of the model group and the training group were 0 at the first day after the injury, and gradually increased on the seventh day onwards (p < 0.05). The BBB score and modified Tarlow score of the training group were higher than those of the model group at the 14th, 21st and 28th day (p < 0.05). The angles of the inclined plate at multiple time points after injury were lower in the model group and the training group than in the normal group and the sham-operated group (p < 0.05); The angles of the inclined plate at the 14th, 21st and 28th day after injury were higher in the training group than in the model group (p < 0.05). Conclusion The mechanism of exercise training may be connected to the inhibition of the Nogo-NgR signaling pathway to promote neuronal growth.

ABSTRACT Objective: to understand the support network in the continuum process of rehabilitation in the daily life of people with spinal cord injury. Methodology: a descriptive study of a qualitative nature, based on Comprehensive Sociology and Everyday Life, with 23 people with spinal cord injury, accompanied by a Nursing and Rehabilitation Service in southern Brazil. For data collection, we used the medical record, genogram, ecomap and individual interview. Content Analysis was used to analyze the interview. Results: when entering the Rehabilitation Program, the support networks were configured as a weak link when inaccessibility was a barrier, specifically, work/school; hobby/leisure. Strong bonds consider the main caregiver networks, health center, friends, religious orientation and family. Final thoughts: the support networks that surround each individual with spinal cord injury and the family and how they relate, help to cope with the new rhythm of life, collaborating to achieve the goals of rehabilitation and resocialization.
ABSTRACT
Endoplasmic reticulum is one of the most important organelles in maintaining cellular homeo⁃ stasis, mainly involved in intracellular lipid synthesis, protein folding and calcium ion homeostasis. Trau⁃ ma, ischemia and hypoxia and other pathological changes can cause protein folding dysfunction in the en⁃ doplasmic reticulum, triggering endoplasmic reticulum stress (ERS). Spinal cord injury (SCI) is a com⁃ mon traumatic disease with anextremely high disability rate, which seriously affects the quality of life. There is no safe and effective clinical methods so far. Investigations have shown that ERS is one of the important pathological changes leading to cell death and neuronal dysfunction after SCI, and is closely as⁃ sociated with signaling pathways such as apoptosis, autophagy, and inflammation in neurons after SCI; however, the molecular mechanisms between ERS and SCI have not yet been thoroughly investigated. A deeper understanding and exploration of the potential molecular mechanisms associated with ERS and SCI may be the future SCI therapeutics. In this paper, we first summarized the relationship between the chan⁃ ges of ERS⁃related genes and the pathological process of SCI, Then the interrelationships between ERS and the apoptosis, inflammation, and autophagy signaling pathways after SCI were analyzed, starting from the three main modes of regulation, including unfolded protein response (UPR), endoplasmic reticulum⁃ associated degradation (ERAD), and endoplasmic reticulophagy (ER⁃phagy),Finally, we summarize the relevant drugs and application prospects of targeting ERS for SCI in recent years, which may provide a theoretical basis for targeting the ERS pathway for SCI and provide some ideas and insights for the de⁃ velopment of future therapeutic strategies after SCI.
ABSTRACT
Axonal demyelination is an important factor causing neurological dysfunction after spinal cord injury. Retaining the integrity of myelin sheath and promoting remyelination play an important role in the functional recovery of spinal cord injury. The bottleneck of the failure of remyelination is the inability of myelin-forming cells (oligodendrocytes and Schwann cells) to differentiate and mature. In recent years related research on spinal cord injury demyelination has found that cell transplantation, neuregulin-1 and hydrogel can effectively enhance remyelination, and identified aquaporin-4 (aquaporin-4, AQP4), metal-loproteinase (Matrix metailoproteinase, MMP) may be a potential therapeutic target to promote myelin recovery after spinal cord injury. This review discusses the research progress of enhancing remyelination after spinal cord injury, providing ideas for the further development of new methods for the treatment of spinal cord injury.
ABSTRACT
Spinal cord injury (SCI) disrupts the structural and functional connectivity between the higher center and the spinal cord, resulting in severe motor, sensory, and autonomic dysfunction with a variety of complications. The pathophysiology of SCI is complicated and multifaceted, and thus individual treatments acting on a specific aspect or process are inadequate to elicit neuronal regeneration and functional recovery after SCI. Combinatory strategies targeting multiple aspects of SCI pathology have achieved greater beneficial effects than individual therapy alone. Although many problems and challenges remain, the encouraging outcomes that have been achieved in preclinical models offer a promising foothold for the development of novel clinical strategies to treat SCI. In this review, we characterize the mechanisms underlying axon regeneration of adult neurons and summarize recent advances in facilitating functional recovery following SCI at both the acute and chronic stages. In addition, we analyze the current status, remaining problems, and realistic challenges towards clinical translation. Finally, we consider the future of SCI treatment and provide insights into how to narrow the translational gap that currently exists between preclinical studies and clinical practice. Going forward, clinical trials should emphasize multidisciplinary conversation and cooperation to identify optimal combinatorial approaches to maximize therapeutic benefit in humans with SCI.

Objective To explore the effect of shionone(SHI)on motor function in the mouse model of spinal cord injury(SCI)and probe into the underlying molecular mechanism.Methods C57BL/6 mice were treated to induce the SCI model and then assigned into a model group(SCI group),a SCI+SHI group,and a sham surgery(control)group.The Basso mouse scale(BMS)score was determined to evaluate the recovery of motor function in SCI mice.Hematoxylin-eosin(HE)staining,Nissl staining,and immunofluorescence staining were employed to examine the fibrosis,morphological changes of neurons,and neuron apoptosis in the spinal cord tissue of SCI mice,respectively.The mouse hippocampal neuronal cell line HT22 was cultured in vitro and then classified into tumor necrosis factor α(TNF-α)induction and SHI groups.Western blotting was employed to determine the expression of apoptosis-associated proteins.Network pharmacology,gene ontology annotation,and Kyoto Encyclopedia of Genes and Genomes pathway enrichment were employed to predict the possible molecular targets and signaling pathways of SHI in promoting functional recovery from SCI.Furthermore,the prediction results were verified by in vitro and in vivo experiments.Results Compared with the SCI group,the SCI+SHI group showed increased BMS score on days 21,28,35,and 42(P=0.003,P=0.004,P=0.023,and P=0.007,respectively),reduced area of spinal cord fibrosis(P=0.021),increased neurons survived(P=0.001),and down-regulated expression of cleaved cysteine aspastic acid-specific protease 3(cleaved Caspase-3)(P=0.017).Compared with the TNF-α group,the SHI group presented down-regulated expression levels of cleaved Caspase-3 and Bax(P=0.010,P=0.001)and up-regulated expression level of Bcl-2(P=0.001).The results of bioinformatics analysis showed that SHI might improve the motor function of SCI mice via the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)signaling pathway.The results of in vivo and in vitro experiments showed that SHI inhibited the phosphorylation of PI3K and Akt in SCI mice or HT22 cells exposed to TNF-α(all P<0.05).The number of apoptotic HT22 cells after treatment with insulin-like growth factor 1 was higher than that in the SHI group(P=0.003).Conclusion SHI may inhibit neuron apoptosis via the PI3K/Akt signaling pathway,thereby promoting the recovery of motor function in SCI mice.

OBJECTIVES@#To observe the clinical efficacy of timing umbilical therapy for neurogenic bladder after spinal cord injury based on the midnight-noon and ebb-flow doctrine.@*METHODS@#Sixty patients with neurogenic bladder after spinal cord injury were randomly divided into a trial group and a control group, with 30 patients in each group. In the trial group, based on the midnight-noon and ebb-flow doctrine, umbilical therapy was given at the time zone, 15:00 to 17:00. In the control group, umbilical therapy was delivered at any time zones except the period 15:00 to 17:00. The herbal plaster was remained on the umbilicus for 4 h each time, once daily. One course of treatment was composed of 2 weeks and the treatment lasted 4 weeks. Before and after treatment, the urodynamic indexes (maximum urinary flow rate [Qmax], maximum detrusor pressure [Pdet-max], residual urine volume [RUV]), voiding diary (average daily number of voiding, average daily number of leakage, average daily voided volume), neurogenic bladder symptom score (NBSS), the score of urinary symptom distress scale (USDS) and the score of World Health Organization quality of life assessment-BREF (WHOQOL-BREF) were compared between the two groups; and the clinical efficacy of the two groups was assessed.@*RESULTS@#After treatment, Qmax, Pdet-max, the average daily voided volume and the scores of WHOQOL-BREF were increased (P<0.05); and RUV, the average daily number of voiding, the average daily number of leakage, NBSS and the scores of USDS were all reduced (P<0.05) in comparison with those before treatment in the two groups. When compared with those in the control group, Qmax, Pdet-max, the average daily voided volume and the score of WHOQOL-BREF were all higher (P<0.05); and RUV, the average daily number of voiding, the average daily number of leakage, NBSS and the score of USDS were lower (P<0.05) in the trial group. The total effective rate was 96.7% (29/30) in the trial group, higher than that (76.7%, 23/30) in the control group (P<0.05).@*CONCLUSIONS@#Timing umbilical therapy, based on the midnight-noon and ebb-flow doctrine, effectively relieves the symptoms of dysuria and improves the quality of life in patients with neurogenic bladder after spinal cord injury.

OBJECTIVE@#To compare the clinical efficacy between electroacupuncture(EA) and moxibustion for neurogenic bladder (NB) after spinal cord injury (SCI).@*METHODS@#One hundred and twenty patients with NB after SCI were randomly divided into an EA group, a moxibustion group, and an intermittent catheterization group, with 40 patients in each group. The patients in the intermittent catheterization group were treated with routine treatment and intermittent catheterization, while the patients in the EA group and the moxibustion group were treated with additional treatments of EA (discontinuous wave, with a frequency of 1.3-1.6 Hz, and intensity based on patient tolerance) and moxibustion, respectively. The acupoints used in both groups were Zhongji (CV 3) and Guanyuan (CV 4), bilateral Zusanli (ST 36), Yinlingquan (SP 9), and Baliao points. Each session lasted for 30 min, once daily, six times a week, for a total of six weeks.The maximum bladder capacity (MBC), residual urine vdume (RUV), detrusor pressure (Pdet) during the filling phase, bladder compliance (BC), maximum renal pelvis separation width of both kidneys, urine white blood cell count, TCM syndrome score, and World Health Organization quality of life assessment-BREF (WHOQOL-BREF) score were compared before and after treatment in the 3 groups. The number of patients in each group who achieved bladder functional balance was recorded, and the clinical efficacy was assessed after treatment.@*RESULTS@#After treatment, the MBC, Pdet, BC, and WHOQOL-BREF scores in the EA group and the moxibustion group were increased (P<0.05), while the RUV, maximum renal pelvis separation width of both kidneys, urine white blood cell count, and TCM syndrome scores were decreased (P<0.05, P<0.01). In the intermittent catheterization group, MBC, RUV, maximum renal pelvis separation width of both kidneys, and urine white blood cell count were decreased (P<0.05), while BC and WHOQOL-BREF score were increased (P<0.05) after treatment. After treatment, the MBC, Pdet, BC, and WHOQOL-BREF scores in the EA group and the moxibustion group were higher than those in the intermittent catheterization group (P<0.05), while the RUV and TCM syndrome scores were lower than those in the intermittent catheterization group (P<0.05). Moreover, after treatment, the MBC and Pdet in the moxibustion group were higher than those in the EA group (P<0.05), while the RUV, maximum renal pelvis separation width of both kidneys, and TCM syndrome score in the EA group were lower than those in the moxibustion group (P<0.05). The number of patients who achieved bladder functional balance after treatment in the EA group and the moxibustion group was higher than that in the intermittent catheterization group (P<0.05). The cured and effective rate was 85.0% (34/40) in the EA group and 82.5% (33/40) in the moxibustion group, which were both higher than 65.0% (26/40) in the intermittent catheterization group (P<0.05), there was no significant difference between the EA group and the moxibustion group (P>0.05).@*CONCLUSION@#EA and moxibustion could effectively improve the functional state of bladder in patients with NB after SCI. EA is more effective in reducing residual urine volume and excessive activity of the urethral sphincter, and relieving TCM syndromes, while moxibustion is more effective in increasing the pressure of the detrusor during the filling period and establishing the detrusor reflex.

Objective：The Clinical Trunk Control Test (CTCT) is used to assess trunk function worldwide, particularly for patients with spinal cord injury (SCI), with good reliability and validity. In Japan, trunk function evaluation methods specialized for patients with SCI are scarce. The aim of the present study was to create a Japanese version of CTCT (CTCT-J) and verify its reliability.Methods：CTCT-J was created using the double-back translation format. The inter-rater reliability was calculated based on the total CTCT-J score and intraclass correlation coefficient (ICC) for each item. The weighted kappa coefficient was calculated for each subtest. To verify internal consistency, Cronbach's alpha coefficient was calculated for the CTCT-J total score and each item.Results：We enrolled 12 patients with SCI, including ten men and two women, with an average age of 51.9 ± 17.8 years. Nine and three patients had cervical and thoracic SCI, respectively. The ICC for inter-rater reliability ranged from 0.995 to 1.000 (p ＜0.05). The weighted kappa coefficient for each subtest ranged from 0.756 to 1.000 (p ＜0.05). In the internal consistency test, the Cronbach's alpha coefficient for all items was 0.995 (p ＜0.05).Conclusion：We created the CTCT-J with double back translation and verified its reliability. Good inter-rater reliability and internal consistency were observed, indicating its applicability in Japan.
ABSTRACT
This report describes a case of an amputee with a lumber spinal cord injury who successfully recovered ambulation with the use of prosthesis.A 30-year-old man with schizophrenia underwent amputation of the lower legs and concurrently developed lumbar spinal cord injury from of a suicide attempt. After the treatment of stump plasty and posterior fusion, the patient was transferred to our facility. Lower-extremity prostheses for both legs were fitted, and orthostatic training was commenced following admission. During the initial evaluation, the patient could not maintain a stable standing position because of weakness in the hip extensor muscle. An inflexion angle of the prosthesis was set to 0° to extend the knee joint and achieve standing stability. Appropriate adjustments of the prosthesis were made as required, specifically addressing the paraplegia caused by his lumbar spinal cord injury. Thus, the patient successfully regained ambulation with the treatment.Recovering walking independence after bilateral lower leg amputations or paraplegia caused by lumber spinal cord injury is not uncommon. However, this case is unique in that the muscle weakness caused by lumbar spinal cord injury presented unforeseen difficulties for the patient to achieve ambulation, which is not ordinarily observed in amputation rehabilitation cases. No similar cases have been reported in which patients concurrently suffered from both these conditions in Japan；therefore, this case is extremely rare.
