“…The minimum hemodynamic effect of NMES to prevent development of DVT is unknown. Studies on hemodynamics during voluntary activation of the muscle pump may however provide comparable data, which demonstrate at least a twofold increase in PVV (13,23,24). Thus, our observed 2-3-fold increases in PVV in v. poplitea and v. femoralis may re ect clinically relevant enhancements of venous velocity for preventing DVT.…”

Background: Neuromuscular electrical stimulation (NMES) may improve venous hemodynamics to decrease the risk of venous thromboembolism. However, whether calf-NMES using textile electrodes integrated in socks can improve venous hemodynamics without discomfort is unknown. Aim: The primary aim of this study was to examine whether calf-NMES, using one new textile electrode- compared to an established gel electrode-setup, could induce significant dose-dependent increases in the peak venous velocity (PVV) and non-inferior comfort.Methods: On ten healthy participants, intensity (mA) of calf-NMES (frequency 36 Hz, phase duration 200µs) was increased until a visible plantar flexion (threshold 1), plus an additional six NMES-levels (threshold II), utilizing two different electrode setups. A new transverse textile electrode (TTE) setup consisted of two textile electrodes (2 x 2.5 cm) sewn into the back of a sock placed 2 cm apart at the largest circumference of the calf. The established gel electrodes (3x3cm) were placed on the participants best motor points and designated the motor point electrode (MPE) setup. PVV was measured in v. poplitea and v. femoralis at baseline and at threshold I and II using a Doppler ultrasound machine. Comfort was assessed with a numerical rating scale (NRS, 0-10). Values were expressed as medians and significance was set to p<0.05.Results: In v. poplitea both TTE and MPE induced significant dose-dependent increases in PVV from baseline to threshold I with 123% and 63% and to threshold II with 319% and 208%, respectively (all p<0.001). TTE, however, resulted in significantly higher increase of PVV in v. poplitea than MPE. In v. femoralis both TTE and MPE induced significant dose-dependent increases in PVV from baseline to threshold I with 47% and 55% and to threshold II with 102% and 107%, respectively (all p<0.001). In v. femoralis, however, there were no significant differences in PPV between TTE and MPE (p=0.700). MPE compared to TTE resulted in lower NRS, 1 versus 2, at threshold I (p<0.001), however at threshold II there was no difference in NRS (p=0.836).Conclusion: A new reusable TTE produces non-inferior dose-dependent venous hemodynamics compared to a standard MPE. Further development, however, is needed concerning textile electrode discomfort to improve patient compliance.Trial registration: Retrospectively registered with ISRCTN registry.

“…Patients assessed via telerehabilitation were provided individualized therapeutic exercises based on early anecdotal reports of high fatigability in patients with COVID-19 and clinical knowledge of therapeutic interventions for similar disease processes such as acute respiratory distress syndrome [3, 14, 15, 23]. Based on muscles important to maintain functional mobility such as ambulation and sit-to-stand transfers, lower extremity muscle groups including gluteals and quadriceps were targeted during supine, seated, and standing exercises [2, 24, 25]. Upper extremity exercises were provided to aid in respiratory function, posture, and functional mobility [18].…”

Background: Guidelines for physical therapy management of patients hospitalized with COVID-19 recommend limiting physical therapists' contact with patients when possible. Telehealth has been viewed as "electronic personal protective equipment" during the COVID-19 pandemic; although telerehabilitation has been shown to be effective with outpatients, it is unknown whether it is a viable option for hospitalized patients. Purpose: Our facility developed an algorithm for the use of a physical therapy telerehabilitation program for inpatients with COVID-19. We sought to investigate the safety and viability of the program. Methods: We conducted a retrospective chart review of patients admitted with a diagnosis of COVID-19 who received either telerehabilitation only or a combination of telerehabilitation and in-person rehabilitation. Based on the algorithm, COVID-19 inpatients were selected to receive telerehabilitation if they could ambulate independently, could use technology, had stable vital signs, required minimal supplemental oxygen, and were cognitively intact. We analyzed data of inpatients who received telerehabilitation only, which included patient education, therapeutic exercises, and breathing techniques. Results: Of 33 COVID-19 inpatients who received telerehabilitation, in-person rehabilitation, or a combination of the two, 12 patients received telerehabilitation only (age range, 33 to 65 years; all but one male). They demonstrated independence with their individualized home exercise programs in one to two sessions, did not require an in-person rehabilitation consultation, did not require increased oxygen, experienced no exacerbation of symptoms, and were discharged home. Conclusions: Inpatient telerehabilitation appears to be a viable option for selected hospitalized patients with COVID-19 and may be a safe way of delivering inpatient rehabilitation to isolated or at-risk populations. At our hospital, the use of inpatient telerehabilitation reduced staff exposure while providing important education and services to patients. To our knowle dg e , no s t u d i e s h a v e i n v e s t i g a t e d t h e us e o f telerehabilitation for hospitalized patients, including those with COVID-19. Our findings suggest that this innovative approach warrants further study.

“…People with haemoglobin above 12.5 g/l are believed to have higher risk of hypercoagulability [ 37 , 38 ]. Using a calf muscle pump pumping blood to the heart, ankle-pumping exercises are widely conducted to prevent DVT [ 39 ]. To conclude, we suggest that there should be further study to verify if rivaroxaban can be used for dilute blood.…”

Effect of rivaroxaban on preventing deep vein thrombosis in aged diabetics with femoral neck fractures after hip replacement

The present study estimates the effect of rivaroxaban on preventing deep vein thrombosis (DVT) in aged diabetics with femoral neck fractures after hip replacement. Our study consisted of 236 aged diabetics with femoral neck fractures, which were divided into the rivaroxaban and control groups. Reaction time (R time), clot formation time (K time), α angle (α), maximum amplitude (MA), clot elasticity (G) and coagulation index (CI), prothrombin time (PT) and activated partial thromboplastin time (APTT) were measured. DVT was diagnosed by color duplex Doppler ultrasound (CDDU). The risk factors of DVT were analysed by logistic regression analysis. Compared with the control group, in the rivaroxaban group, R time and K time were extended and α, MA and G decreased 1 day before operation. One day after operation, the rivaroxaban group had less PT and APPT and lower incidence of DVT than the control group. In the two groups, preoperative and postoperative PT and APPT significantly differed. Body mass index (BMI) ≥25, abnormal coagulation indicators, use of cemented femoral hip prosthesis, high haemoglobin content and non-ankle pump exercise after operation were the risk factors for DVT. Rivaroxaban could prevent DVT in aged diabetics with femoral neck fractures after hip replacement.
