简要总结
Patients post total hip arthroplasty (THA) remain at high risk of developing Deep Vein Thrombosis (DVT) during the recovery period following surgery despite the availability of effective pharmacological and mechanical prophylactic methods. The use of calf muscle neuromuscular electrical stimulation (NMES) during the hospitalised recovery period on this patient group may be effective at preventing DVT. However, the haemodynamic effectiveness and comfort characteristics of NMES in post-THA patients immediately following surgery have yet to be established.
The main objectives are:
- To establish if patients in the early post-operative period have tolerance for NMES.
- To determine if applying NMES to patients immediately post-THA increases venous outflow from the lower limb over resting conditions.

结局指标
主要结局
Lower limb haemodynamic performance
时间窗: 4 hours
Duplex Doppler ultrasound will be used as the outcome measure. Both legs will be measured for hemodynamic performance in the popliteal vein by placing the probe at the popliteal fossa. Measurements of peak venous velocity (cm/s), popliteal vein diameter (cm), time averaged mean velocity (TAMEAN, cm/s) and volume flow (ml/min) will be recorded. Doppler measurements will be taken initially at rest, before the application of NMES and once again when the NMES session had commenced.
次要结局
- Patient comfort during application of NMES(4 hours)
