Context: We sought to describe our experience with the Hybrid Assistive Limb® (HAL®) for active knee extension and voluntary ambulation with remaining muscle activity in a patient with complete paraplegia after spinal cord injury.
Findings: A 30-year-old man with complete paraplegia used the HAL® for 1 month (10 sessions) using his remaining muscle activity, including hip flexor and upper limb activity. Electromyography was used to evaluate muscle activity of the gluteus maximus, tensor fascia lata, quadriceps femoris, and hamstring muscles in synchronization with the Vicon motion capture system. A HAL® session included a knee extension session with the hip flexor and voluntary gait with upper limb activity. After using the HAL® for one month, the patient’s manual muscle hip flexor scores improved from 1/5 to 2/5 for the right and from 2/5 to 3/5 for the left knee, and from 0/5 to 1/5 for the extension of both knees.
Conclusion/clinical relevance: Knee extension sessions with HAL®, and hip flexor and upper-limb-triggered HAL® ambulation seem a safe and feasible option in a patient with complete paraplegia due to spinal cord injury. 相似文献
In patients with non-tuberculous mycobacterial cervicofacial lymphadenitis, incomplete surgical removal of infected lymph nodes leads to delayed healing and a higher recurrence rate, with eventual spontaneous drainage through the skin. However, complete surgical removal is not always achievable due to the extent of the infected tissue and proximity to vulnerable structures, such as the facial or accessory nerve. The aim of this study was to identify the clinical determinants of the (in)ability to perform complete surgical removal. The electronic health records of patients aged 0–15 years with bacteriologically proven non-tuberculous mycobacterial cervicofacial lymphadenitis, who underwent surgical treatment and preoperative sonographic imaging, were analysed. This was a case–control study. A total of 103 patients met the inclusion criteria. Most of the infections were unilateral, submandibular, and caused by Mycobacterium avium. Multiple logistic regression analysis revealed that higher age (odds ratio 1.24, 95% confidence interval 1.04–1.47) and fistulization (odds ratio 3.15, 95% confidence interval 1.13–8.75) were significantly associated with a limited ability to surgically remove all infected tissue. However, a larger sonographic lymph node size was not significantly associated. These findings could aid clinicians when informing the parent(s)/guardian(s) of the patient preoperatively and in properly estimating the intraoperative and postoperative course. 相似文献
