The computer access, such as special mouse keyboard, software of the voice input and the magnified or reading screen, etc., can facilitate the people with disabilities to use the computer more efficiently. The computer access adaption should be evaluated to meet the users' needs, their function and the circumstances in which they live. The products should be easily designed, remade, and used for the cus-tomers and the prices should be available. For China, it is important to form professional teams, establish the good service process, achieve more supports, especially financial support, to research and develop more varieties of products.

OBJECTIVE: Observed the using of coblation during the maxillary sinus operation, to investigate the superiority of its clinical application. METHOD: Selecting 46 patients with the maxillary sinus lesions of sinusitis, nasal polyps and nasal inverted papilloma as research objects, the control group used high speed cutting drill, the research group used coblation separately for functional endoscopic sinus surgery. Six months postoperative follow-up, observeing the subjective symptoms and objective examination. RESULT: Subjective symptoms and objective examination scores of two groups of patients improved significantly. Compared with the control group, the operation time, bleeding volume and postoperative examination time are reduced in the study group of patients. Endoscopic examinations of the study group are better than the control group. CONCLUSION Using coblation for the maxillary sinus operation, treatment are more thorough, more minimally invasive, shorten operation time, reduce bleeding and recheck time after surgery, is worthy of clinical use.

ObjectiveTo design a weight-bearing pressure casting system for transtibial prostheses to make the total surface bearing socket and to control the stump and bearing during the casting process.MethodsThe weight-bearing pressure casting system was designed. 6 cases weared the socket by this method and traditional patellar tendon bearing socket by hand casting. Socket interface pressure was compared, and the effect of casting was assessed.ResultsCompared with patellar tendon bearing socket, the socket pressure in the socked by this method was distributed more equally throughout the transtibial residual limb during the casting process, and completed the stumps compression and stump-end pressure control.ConclusionWeight-bearing pressure casting system can make the total surface bearing socket, and improve the fit of the socket.

This paper elaborated that wheelchairs are the most important assistive devices for people with mobility impairment to maintain their health, improve their quality of life and promote their social participation. The situation of low service level was analyzed due to the lack of knowledge, organizations, professionals and products. Based on the foreign standard of practice for wheelchair service, the strategies and steps of wheelchair service provision in China were carried out to arouse the attention of relevant professionals, who could be active participants in wheelchair service practice and research

OBJECTIVE: To investigate the sleep monitoring feature of the MSMS in elderly patients with OSAHS. METHOD: One hundred and ninety patients diagnosed with OSAHS were divided into elderly group and non elderly group according to age, then the results of MSMS were analyzed. RESULT: Majority elderly patients were with mild to moderate OSAHS. The nocturnal mean blood oxygen and the lowest oxygen were higher than non elderly group, coupled with higher percentage of the total oxygen saturation < 90% monitoring time (TS90). There was no significant difference in sleep structure between two groups, but the total sleep time of elderly group is lower than the non elderly group, the difference is statistically significant. CONCLUSION The elderly patients with OSAHS were less severe in nature, but the nocturnal hypoxia last longer in the elderly group. There is no significant difference in the sleep structure between the two groups. But the total sleep time decrease in elderly group. With smaller interference, the MSMS is closer to the natural sleep stustus of the subjects.

OBJECTIVE: To investigate the result of child-type micro-sensitive mattress sleep monitor on obstructive sleep apnea-hypopnea syndrome in children. METHOD: The PSG and child-type micro-sensitive mattress sleep monitor were synchronously performed on 58 cases of children with OSAHS. The breathing and sleep metrics were compared. RESULT: By PSG monitoring, 41 cases were diagnosed as mild OSAHS, 14 cases were moderate and 3 cases were severe. The results of mattress system monitoring showed mild OSAHS in 37 cases, 16 cases of moderate and severe OSAHS in 5 cases. Seven patients diagnosed as mild OSAHS monitored by PSG were classified as moderate by mattress system monitoring; three cases diagnosed as mild OSAHS by mattress system monitoring system were diagnosed as moderate by PSG. Among 14 cases of children diagnosed as moderate by PSG, three cases were diagnosed as mild by mattress system monitor and two cases as severe. Children diagnosed as severe by PSG got the same result by mattress system monitor. Two kinds of sleep monitoring methods were compared and there were no statistically significant difference in AHI (t = 2.316, P > 0.05), deep and shallow sleep constituent ratio (t = 2.280, t = 2.388, PF > 0.05). while there was significant difference in REM period Sleep constituent ratio (t = 3.135, P < 0.01). CONCLUSION Child-type micro-sensitive mattress is in good agreement with the PSG for diagnosing OSAHS in children, which can be used as a monitoring method in clinical work.

OBJECTIVE: To investigate the therapeutic efficacy of coblation-assisting uvulopalatopharyngoplasty (CAUPPP) combining with coblation-channeling of the tongue (CCT) for patients with severe obstructive sleep apnea-hypopnea syndrome (OSAHS). METHOD: A retrospective analysis was made on patients with severe OSAHS treated by CAUPPP combining with CCT. The adult with severe OSAHS were involved in the study and the apnea-hypopnea index (AHI) were beyond 40/h and lowest arterial oxygen saturation (LSaO2) were under or equal to 80%. Surgical approach: The UPPP was performed to decrease the size of soft palate with coblation and coblation-channeling in the soft palate and decrease the size of tongue by CCT. All patients were followed up for 6 to 12 months and underwent polysomnography (PSG). RESULT: Subjective symptoms of patients improved more significantly than that of preoperation. The function of soft palate is normal without significant nasopharyngeal regurgitation. Compared with the preoperative data, AHI values were significantly decreased (P<0.01) and the lowest oxygen saturations increased significantly (P<0.01) and the effective rate was 91.7%. CONCLUSION There are usually multiple obstruction levels in patients with severe OSAHS and the traditional surgical treatment is not ideal. This study demonstrated that with the assistance of coblation, combining CAUPPP with CCT for patients with severe OSAHS is an effective surgical method. It has less blood loss, minimally invasive, retained the normal function of the soft palate, etc., should be widely applied.

The clinical manifestation, physical and laboratory examination, electrophysiological, and imaging data of 2 female adult OMS patients with vertigo were analyzed at the Department of Neurology of the First Medical Center of Chinese PLA General Hospital from February 2021 to March 2022. The treatment strategy and clinical outcome were followed up. The two female patients were aged 42 and 66 years. Anti-NMDA receptor antibody and anti-GABAB receptor antibody were detected in serological screening, respectively. The two patients met the diagnostic criteria for OMS, and one was screened for breast tumor. The clinical symptoms of the two patients were relieved after immunomodulation therapy. OMS is a group of rare clinical syndromes; its clinical evaluation process should be standardized and the etiology should be actively searched for.

Objective To carry out the function evaluation and clinical adaptation service of assistive devices for a bilateral wrist-palm disarticulation case in the framework of International Classification of Functioning, Disability and Health (ICF). Methods By evaluating dysfunction and actual demand of the case, assistive devices were selected and applied in daily living, home, education and employment to achieve corresponding accessibility in activities and participation. Results and Conclusion The framework of ICF is important in evaluation of limb dysfunction and adaptation of assistive devices.
