BACKGROUND: Neuromuscular electrical stimulation (NMES) is a complementary tool for therapeutic exercise for muscle strengthening and may potentially enhance exercise performance. OBJECTIVE: To determine whether high-intensity interval training (HIIT) and continuous aerobic training (CA) coupled with NMES enhance the changes in the eccentric/concentric muscle contraction patterns of hamstring and quadriceps. METHODS: Forty-five healthy sedentary male participants performed cycling training 3 times per week for 8 weeks combined with/without NMES performed at a load equivalent to 65% and 120% of IVO2max (intensity associated with the achievement of maximal oxygen uptake). Anthropometrics, blood lactate measurements, IVO2max, TLimVO2max (time-to-exhaustion) and isokinetic strength parameters were measured at baseline and post-training using a randomized controlled trial. RESULTS: The conventional hamstring-to-quadriceps-ratio (HQR: Hcon/Qcon) at 60∘/s and the Dynamic Control Ratio (DCR: Hecc/Qcon) at 180∘/s significantly increased both in the dominant (D) and non-dominant (ND) limb in the HIIT + NMES group (p< 0.05). There was a positive significant correlation between the individual changes in D HQR at 60∘/s and IVO2max (r= 0.94, p= 0.005) and the DCR at 180∘/s and TLimVO2max (r= 0.90, p= 0.015), respectively. CONCLUSIONS: The increases in the eccentric muscle contraction and DCR following HIIT + NMES seem to improve fatigue tolerance, cause less fatigue and oxidative stress on the lower limb during pedaling at high intensities.

ObjectivesTo describe the acceptability, safety and effectiveness of neuromuscular electrical stimulation (NMES) in infants and young children with neurological impairment (NI) who have severe dysphagia.DesignA prospective pilot study using a before and after study design.SettingThe Hospital for Sick Children, Toronto, Canada.PatientsTen infants and young children (0–24 months) with NI and severe dysphagia on videofluoroscopic swallow study (VFSS) who were referred to an occupational therapist (OT). Those with neurodegenerative conditions were excluded.InterventionNMES treatments lasting 20–45 min twice weekly for the duration of 2–4 months. The NMES was administered during feeding therapy sessions by a trained OT.Main outcome measuresImprovement in swallowing function as measured by VFSS and the need for tube feeding, adverse events and parental acceptability.ResultsSeven of 10 enrolled subjects (median age, 8.9 months) completed biweekly NMES treatments (median number of treatments per subject, 18). All of the seven (100%) subjects who completed treatment showed an improvement in swallow function on VFSS. Of the five patients who were not safe to orally feed on any consistency of liquid or puree at baseline, three established full oral feeding and two established partial oral feeding. At baseline, 5/7 children were completely fed by tube versus 0/7 at the end of treatment. No adverse events occurred other than mild skin irritation at the site of electrode placement. Five of seven caregivers felt that feeding was improved and were satisfied with the intervention.ConclusionsOur prospective pilot study of NMES in seven neurologically impaired infants and young children with severe dysphagia suggests that NMES is safe, acceptable to parents and has potential efficacy. Trials are needed to determine if any treatment benefit exists.Trial registrationClinicalTrials.gov NCT01723358.
