Objective: Using biofeedback in instructing pelvic floor muscle (PFM) activation is a great method to provide information on muscle contraction. This study aimed to determine the immediate effectiveness of a mobile game-based instruction with an extracorporeal biofeedback device (EBD) to improve PFM contraction in healthy subjects. Design: Cross-sectional study. Methods: Sixteen healthy subjects (4 men and 12 nulliparous women; age, 31±5 years) were enrolled. The subjects were randomly categorized into two groups, those who were to receive instructions on how to contract the PFM by using the EBD (n=7) and those who were to undergo a transabdominal ultrasonography (TAUS; n=9) with biofeedback. PFM function was measured as the displacement (mm) of PFM elevation by using the TAUS before and after the instructions in each group. Results: The EBD and TAUS groups showed a significant increase in the displacement of PFM elevation after the instructions from 5.93±4.03 mm to 7.62±3.77 mm and from 5.27±3.39 mm to 7.47±2.79 mm, respectively (p<0.05). No significant differences were found between the two groups. Conclusions: The results of this study indicated that instructions for PFM contraction using the EBD and TAUS showed an immediate effect; however, no significant difference in effectiveness was observed between the two instruction methods. Therefore, not only can the TAUS method be used but the EBD method can also be used as a PFM instruction method for noninvasive procedures. However, further studies are needed to demonstrate the effectiveness of training and exercise on larger sample sizes that includes patient populations with PFM dysfunction.

Background: This study aimed to determine: the perspectives of the patient cohort that underwent telehealth consultation and shoulder rehabilitation during coronavirus disease 2019 (COVID-19) and the differences in the patients' perspectives with the two different telehealth video applications (apps) used in the study. Methods: This is a prospective study carried out during the COVID lockdown period of April to July 2020. Thirty consecutive patients from the orthopedics department of a tertiary institute in India underwent their first-ever session of a video app-based (Zoom or WhatsApp) telehealth consultation with shoulder rehabilitation exercises on a handheld mobile, tablet, or laptop device. After the virtual consultation, the patients were sent a validated telehealth usability questionnaire (TUQ) to evaluate their perspectives. Scores obtained from the TUQ were the primary outcome measure. Results: The study was completed by 30 patients (16 men and 14 women) with an average age of 56 years (range, 20-77 years). The patients who contacted us during the lockdown period with either a stiff shoulder or a conservatively treated shoulder fracture were included in the study. The average TUQ score was 13.6 (median, 14.5; range, 6-21) out of a maximum of 21 points. Eighty percent of the patients were satisfied and found the telehealth service useful. Use of the Zoom app scored significantly higher (median, 17; average, 15.6) than the WhatsApp app (median, 8.5; average, 9.6) (p=0.004). Conclusions: Patients who received telehealth consultation and shoulder rehabilitation were overall satisfied. Telehealth apps with advanced video calling features such as Zoom should be preferred for higher patient satisfaction.
