Skin frictional properties of four kinds of prosthetic materials in common use have been researched. Experiments are carried out on residual limb and on normal tibia. Surface roughness and the hydrophobic/hydrophilic of the skin and materials are also tested. Under normal load 0.3 N and 0.7 N, the friction coefficient of silicon rubber and skin has the maximum value among all the materials due to the surface property of silicon rubber (containing oil). There is remarkable difference in friction coefficient between normal skin and amputee skin when they are in contact with silicon rubber (P<0.05). Other materials show "the higher the hydrophobia tendency of surface, the lower the friction coefficient". There are no significant differences (P>0.05) in friction coefficient between amputee skin and normal skin when they are in contact with all materials under normal load 8 N.

Objective To analyze the gait kinematics parameters of patients with unilateral leg amputation after wearing prosthesis using the computer assisted rehabilitation environment (CAREN) gait assessment system,and the reasons for the differences.Methods Nine patients with unilateral mid-leg amputation were selected as the prosthesis group,and 11 healthy subjects were selected as the standard group.The gait kinematics parameters of the two groups were collected,processed and analyzed by using the CAREN gait evaluation system.Results The gait phase index of the prosthetic limb group was (0.88±0.04).Significant differences were observed between the prosthetic and healthy limbs in terms of step length,stance phase percentage,maximum hip extension angle and maximum knee flexion angle,maximum dorsiflexion and plantar flexion angle of the ankle joint during the stance phase,as well as the dorsiflexion angle of ankle joint during heel strike to the ground (P＜0.05).Moreover,there were significant differences between the affected limbs of the prosthetic limb group and limbs of the standard group in terms of the walking speed,gait cycle,stride length,percentage of stance phase,hip flexion angle,knee flexion and ankle dorsiflexion during heel strike,maximum hip extension and flexion angle,maximum dorsi-and plantar-flexion of ankle joint during stance phase (P＜0.05).Conclusion The relative symmetry of the gait of the unilateral leg amputee is (0.88±0.04),with their kinematics parameters of the prosthetic limb significantly weaker than those of the contralateral side and the healthy controls.

ObjectiveTo investigate the unmet needs for assistive technology for people with physical disabilities in Chengdu, and analyze the related factors. MethodsFrom November, 2023 to March, 2024, the persons with physical disabilities in Chengdu were selected from Sichuan Individuation service platform, and investigated using World Health Organization rapid Assistive Technology Assessment. ResultsA total of 558 questionnaires were set up, and 527 effective questionnaires retured. 26.8% of them reported unmet needs for aids, with the highest need for mobility aids (66.0%). Lack of support (54.9%), high price (26.3%) and lack of knowledge about aids (20.3%) were the main reasons for not obtaining the aids they needed. Loss of spouse (OR = 3.615), serious mobility impairment (OR > 2.926) and serious self-care impairment (OR > 2.781) were the risks of unmet needs for aids. ConclusionIt is important to popularize policies and products of aids, pay attention to personal adaptation for people with different barriers, and strengthen the service system, to meet the needs of people with disabilities.

Objective     To compare the clinical efficacy and safety of da Vinci robot with totally no tube (TNT) versus subxiphoid video-assisted thymectomy surgery (SVATS) in the treatment of thymic tumors. Methods     From 2019 to 2021, a retrospective analysis was conducted on patients with thymic tumor resection in the Department of Thoracic Surgery, General Hospital of Northern Theater Command. All patients underwent total thymectomy and mediastinal fat removal, and they were divided into a TNT group and a SVATS group according to the operation method. The intraoperative blood loss, conversion rate, postoperative visual analogue score (VAS), postoperative hospital stay time and postoperative complications were compared between the two groups. Results     We finally included 435 patiets. There were 168 patients with 83 males and 85 females at an average age of 61.920±9.210 years in the TNT group and 267 patients with 147 males and 120 females at an average age of 61.460±8.119 years in the SVATS group. There was no death or postoperative myasthenic crisis in both groups. There was no statistical difference in postoperative hospital stay (1.540±0.500 d vs. 3.400±0.561 d, P=0.000), intraoperative blood loss (13.450±5.498 mL vs. 108.610±54.462 mL, P=0.000), postoperative 24 h VAS score (4.960±1.757 points vs. 3.600±1.708 points, P=0.000), or postoperative complication rate (3.0% vs. 11.6%, P=0.001). Conclusion     TNT is a more efficient, safe, and effective surgical approach for treating thymic tumors, which can shorten hospital stay time and reduce postoperative complications. However, SVATS can minimize postoperative pain.
