The objective of this study was to determine if wheelie training that begins with learning how to balance with the front wheels on a ramp would increase the success rate, reduce the training time, and improve retention rates. A randomized controlled trial design was used to evaluate the effectiveness of wheelie training on a ramp setting (ramp group, n = 26) and conventional training (conventional group, n = 26). The main outcome measures were success rates in achieving wheelie competence, training time, and the retention rate in 7 and 30 days respectively. The results showed that the success rate for each training group both reached 100%. The mean training times for the conventional group and the ramp group were 86.0 ± 35.7 and 76.0 ± 25.8 minutes. Training time was not significantly affected by the training method (p = 0.23), but it was affected by gender, with women requiring an average of 92.0 ± 31.4 minutes in comparison with 70.0 ± 27.5 minutes for men (p = 0.01). The skill retention rate after 7 and 30 days was 100% for both groups. Neither success rate nor training time for wheelie skill acquisition by learners were improved by learning wheelie balance on a ramp. However, a high retention rate of wheelie skills for both training groups was found, which implies that success can be achieved by training on a ramp used in this study.

Purpose. This study aimed to investigate the shear displacement between the body and backrest/seat, range of motion (ROM), and force acting on the lower limb joints during sit-stand-sit transitions by operating an electric-powered standing wheelchair. Methods and Materials. The amounts of sliding along the backrest and the seat plane, ROM of lower limb joints, and force acting on the knee/foot were measured in twenty-four people with paraplegia. Results. Without an antishear mechanism, the shear displacement was approximately 9 cm between the user's body and the backrest/seat surfaces. During standing up, the user's back slid down and the thigh was displaced rearward, but they moved in opposite directions when wheelchair sat back down. A minimum of 60 degrees of ROM at the hip and knee was needed during sit-stand-sit transitions. The maximal resultant forces acting on the knee restraints could reach 23.5% of body weight. Conclusion. Sliding between the body and backrest/seat occurred while transitioning from sitting to standing and vice versa. A certain amount of ROM at lower limb joints and force acting on the knee was necessitated during sit-stand-sit transitions. Careful consideration needs to be given to who the user of the electric powered standing wheelchair is.

Spasticity, a common stroke complication, can result in impairments and limitations in the performance of activities and participation. In this study, we investigated the effectiveness of a new dynamic splint on wrist and finger flexor muscle spasticity in chronic stroke survivors, using a randomized controlled trial. Thirty chronic stroke survivors were recruited and randomly allocated to either an experimental or control group; 25 completed the 6-week intervention program. The participants in the experimental group were asked to wear the dynamic splint at least 6 h/day at home, for the entire intervention. The participants in the control group did not wear any splint. All the participants were evaluated 1 week before, immediately, and after 3 and 6 weeks of splint use, with the modified Ashworth scale and the Fugl−Meyer assessment for upper extremity. User experience was evaluated by a self-reported questionnaire after the 6-week intervention. The timed within-group assessments showed a significant reduction in spasticity and improvements in functional movements in the experimental group. We found differences, in favor of the experimental group, between the groups after the intervention. The splint users indicated a very good satisfaction rating for muscle tone reduction, comfort, and ease of use. Therefore, this new splint can be used for at-home rehabilitation in chronic stroke patients with hemiparesis.
