The safety and feasibility of a new rehabilitation robotic exoskeleton for assisting individuals with lower extremity motor complete lesions following spinal cord injury (SCI): an observational study.

STUDY DESIGN: A pre-post observational study. OBJECTIVES: To evaluate the safety and feasibility of a new rehabilitation robotic device for assisting individuals with lower extremity motor complete lesions following spinal cord injury (SCI). SETTING: Three hospitals in Sichuan Province, China. METHODS: Individuals aged 15-75 years with an SCI between vertebrae six (T6) and lumbar 1 (L1) and complete motor paralysis participated in an exoskeletal-assisted walking (EAW) programme (2 weeks, 5 days/week, 30 min/day). Data were collected pre-, mid- (week 1) and post-intervention (week 2). RESULTS: Twenty-eight individuals (mean age = 41.3, 71% males) participated in the EAW programme. The distance walked during the 6-min walking test (6MWT) increased relative to that at baseline, during week 1 (13.0 ± 5.3 m) and week 2 (16.2 ± 5.3 m) when wearing the exoskeleton. The walking speed during the 10-m walking test (10MWT) increased from 0.039 ± 0.016 to 0.045 ± 0.016 m/s. The Hoffer walking ability grade, the Spinal Cord Independence Measure (SCIM), and the Walking Index for SCI II (WISCI II) changed after 2 weeks of EAW. No improvement in lower extremity motor score (LEMS) was observed. The rates of adverse events and serious adverse events were 21% and 4%, respectively. CONCLUSIONS: The EAW programme with the new robotic exoskeleton provided potential meaningful improvements in mobility for individuals with SCI and had few adverse events.

Bladder management of patients with spinal cord injuries sustained in the 2008 Wenchuan earthquake.

This study's aim is provide an overview of the patients who suffered spinal cord injury (SCI) after the magnitude 8.0 Wenchuan earthquake, including each patient's demographic and epidemiological characteristics, bladder management status, and quality of life (QOL). We also assessed the relationships between bladder management methods, symptomatic urinary tract infection (SUTI), and QOL. Two years after the 2008 Wenchuan earthquake, a cross-sectional face-to-face survey was conducted on 180 patients with SCI. A self-administered questionnaire and the WHOQOL-BREF assessment were used to assess injury-related information, bladder management methods, and SUTI. Statistical analysis was performed using the Chi-square test and analysis of variance. A p value <0.05 was considered statistically significant. This study found that a male-to-female ratio of approximately 1.2:1, including 98 (54.4%) male patients and 82 (45.6%) female patients. Thoracic-level injuries were seen in 82 patients (45.56%), 60 (33.33%) patients had lumbar-level injuries, 18 (8.33%) patients had thoracolumbar-level injuries, and a small number of patients had cervical- or sacral-level injuries. Sixty-two patients (34.44%) demonstrated normal voiding, 65 (36.11%) required manually assisted voiding, 29 (16.11%) required catheterization, and 24 (13.33%) used aurine-collecting apparatus. The prevalence of SUTI was 43.89%. Patients who emptied their bladder via manually assisted voiding, catheterization, or with the use of a urine-collecting apparatus demonstrated higher rates of SUTI compared with patients who voided normally (p < 0.05); the patients who required catheterization had higher rates of SUTI compared with patients who required manually assisted voiding (p < 0.05). When manually assisted voiding and catheterization were compared with the use a urine-collecting apparatus, no statistically significant differences were observed in terms of the risk of developing SUTI. The patients in this study demonstrated low scores on the WHOQOL-BREF physical domain (11.61 ± 3.80), psychological domain (10.11 ± 3.63), social domain (11.46 ± 2.84), and environmental domain (11.86 ± 2.51). The patients who reported normal voiding also demonstrated the best QOL in terms of physical, psychological, and social component scores (p < 0.05). In conclusion, the percentage of women in this study is higher than that reported in other studies on traumatic causes of SCI. Patients who suffered SCI following the Wenchuan earthquake demonstrate poor bladder management status and are unable to take advantage of urodynamic testing that is used to monitor the functional state of the bladder. This study's findings indicate that bladder management methods influence the rate of SUTI and the QOL of patients with SCI. Caring for SCI patients following a disaster requires comprehensive long-term planning. Bladder management of patients with SCI is essential for improving the QOL of these patients.

[A case of comprehensive rehabilitation of trismus after extraction].

There are many therapies to treat the trismus, such as durg therapy, occulusal splints, pulsing electromagnetic fields, medical iontophoresis, laser, acupuncture. But there are no objective criterias about the most effective methods. The patient with trismus after extraction was cured by using comprehensive rehabilitation including physical therapy (ultrashort wave electrotherapy, medical iontophoresis, middle frequency electrical therapy), traditional Chinese manipulation, functional training, muscular and joints traction. The patient recovered completely with satisfactory. Thus this method had the advantage of painless, noninvasive and non-stimulation with well clinical practice.
