[Purpose] Bicycle saddle height is a critical factor for cycling performance and injury prevention. The present study compared the variance in cadence frequency after exercise fatigue between saddle heights with 25° and 35° knee flexion. [Methods] Two saddle heights, which were determined by setting the pedal at the bottom dead point with 35° and 25° knee flexion, were used for testing. The relative variances of the cadence frequency were calculated at the end of a 5-minute warm-up period and 5 minutes after inducing exercise fatigue. Comparison of the absolute values of the cadence frequency under the two saddle heights revealed a difference in pedaling efficiency. [Results] Five minutes after inducing exercise fatigue, the relative variances of the cadence frequency for the saddle height with 35° knee flexion was higher than that for the saddle height with 25° knee flexion. [Conclusion] The current finding demonstrated that a saddle height with 25° knee flexion is more appropriate for cyclists than a saddle height with 35° knee flexion.

Intradialytic hypotension (IDH) is a very common complication during hemodialysis. IDH may lead to nausea, vomiting, or anxiety. In some severe cases, it may cause shock or death. Each hemodialysis treatment generally lasts for four to six hours and must be repeated two or three times a week. Currently, the hemodialysis procedure may lead to dangerously low blood pressure when blood pressure is not frequently assessed by medical staff. Therefore, the purpose of this work is to use the technologies of wireless sensor networks (WSN), global systems for mobile communications (GSM), and a MySQL database to develop a PC-based gateway and an automatic monitoring system to collect physiological data during hemodialysis and continuously monitor the IDH status of patients. The clinical definition of IDH during hemodialysis is a decrease in the systolic pressure of at least 20 mmHg and a decrease in the mean arterial pressure (MAP) of at least 10 mmHg. Our system uses a threshold-based algorithm to monitor and record the systolic and mean arterial blood pressure readings. The GSM module is utilized to send medical staff a warning message, and the message is displayed on the monitor if the readings reach a critical point. The experimental results show that this monitoring system is highly reliable.

[Purpose] This study investigated the effects of low-level laser phototherapy on hand and forearm fractures. [Subjects and Methods] This was a one-group pretest-posttest design study. We recruited 9 patients with hand or forearm fracture, and they received diode laser treatment (808 nm, 10 Hz, 60 mW). Evaluation of pain on a visual analog scale (VAS) and radiographic assessments were made pre-intervention, post-intervention, and at two weeks of follow-up. [Results] There were significant differences in VAS scores between pre-intervention and post-intervention and between pre-intervention and 2 weeks of follow up. In the radiographic assessment, the percentage of detectable cortical bridging also increased significantly after phototherapy. [Conclusions] We consider that low-level laser phototherapy is effective for human bone healing and pain relief.
