Fig. 4From: Intradialytic neuromuscular electrical stimulation with optional virtual reality distraction improves not only muscle strength and functional capacity but also serum albumin level in haemodialysis patients: a pilot randomized clinical trialBoxplot—Individual intensity (milliampere) of stimulation in each group. Adverse events. mA: milliampere; NMES: Neuromuscular electrical stimulation; NMES + VR: Neuromuscular electrical stimulation + virtual reality. Note: For the evaluation of the VAS, 429 interventions of the NMES group and 98 of the NMES + VR group could be considered in the analysisBack to article page
