Effects of neuromuscular electrical stimulation combined with resistance exercises on muscle strength in adult hematological cancer patients: A randomized controlled study

We compared the effects of resistance exercise (REx) and resistance exercise combined with neuromuscular electrical stimulation (NMES+REx) on muscle strength, functional lower extremity strength, and mobility in hematological cancer patients during chemotherapy. Forty-three adult patients were recruited and randomized into the REx group versus personalized and progressive NMES+REx. The lower extremity muscle strength (digital hand dynamometer) test and functional and mobility tests [30-s sit-to-stand test, Timed Up and Go test (TUG)] were performed pre-and postintervention. The Eastern Cooperative Oncology Group-Performance Score (ECOG-PS) of 90% of all patients was ≥2. Increases in steroid dose after transplantation were associated with decreases in hip flexion and knee extension muscle strength values (respectively; rs:-0.468, p:0.008; rs:-0.527, p: 0.002). There was a significant improvement in strength measurement, functional and mobility tests, and ECOG-PS in both groups (p
