Objective: To investigate the effects of respiratory muscle training (RMT) combined with the abdominal drawingin maneuver (ADIM) on the pulmonary function in patients with chronic spinal cord injury (SCI). Methods: Thirty-seven subjects with SCI (level of injury: C4-T6, time since injury: 4-5 years) were randomly allocated to three groups; the integrated training group (ITG), the RMT group (RMTG), and the control group (CG). The ITG performed RMT using an incentive respiratory spirometer (IRS) and the ADIM using a stabilizer. The RMTG received only RMT using an IRS. Subjects in the CG received alternative and routine physical therapy or usual care. The interventions were conducted over an eight-week period. Pulmonary function was evaluated using spirometry to measure the forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV 1 ). Results: The differences between the pre-and post-test values for FVC (0.47 ± 0.05 versus 0.15 ± 0.06 versus -0.03 ± 0.01) and FEV 1 (0.74 ± 0.07 versus 0.27 ± 0.17 versus 0.02 ± 0.67)were significant among the groups. Post-test, in the ITG, the FVC and FEV 1 values showed significant differences from those in the RMTG and CG (F = 11.48 and 11.49, P = 0.002 and 0.001). Furthermore, following the 8week intervention, the change ratio values of the FVC and FEV 1 of the ITG were increased further by an average of 9.75% and 7.91%, respectively, compared with those of the RMTG. Conclusion: These findings suggest positive evidence that RMT with additional ADIM training can improve pulmonary function in SCI pulmonary rehabilitation.

[Purpose] The aim of this study was to determine the effect of spatial target reaching training (TRT) based on visual biofeedback (VB) on the upper extremity (UE) function of hemiplegic subjects. [Subjects and Methods] Forty subjects between six and eighteen months post-stroke were enrolled in this study. They were randomly allocated to an experimental group (EG, n=20) and a control group (CG, n=20). All subjects received an hour of routine therapy for stroke three times a week for four weeks. Subjects in EG received additional spatial TRT based on VB using a 2-dimensional motion capture analysis system. Both groups were tested at pre and post-intervention. The motor function of each subject’s UE was assessed using the Fugl-Meyer (FM) test of UE and the Wolf Motor Function Test (WMFT). The reaching speed, angle and maximum reach distance were recorded using the motion capture analysis system. The experimental data were analyzed using the paired and independent t-tests. [Results] The mean change scores of the FM Test of UE and WMFT show there was significantly more improvement at post-intervention in EG than in CG. Also, the speed and angle reached showed significantly more increase in the EG compared with the CG. [Conclusions] The findings indicate that UE motor recovery of hemiplegic stroke patients can be enhanced through the use of TRT based on VB.

Although LCDs are widely used in power‐consumption critical applications, they are not very energy‐efficient. The largest absorber of light is the color filter. We developed a TFT‐LCD with four‐color subpixels: red, green, blue and white. The addition of the white subpixel greatly enhanced the light efficiency: up by 50%. The RGB‐to‐RGBW mapping algorithm was designed so that the hue and saturation remains unchanged from the original color. The result is a very bright display with color characteristic almost identical to RGB LCDs.
