Document Summary

Neuromuscular electrical stimulation (nmes) to improve muscle quality and function. The application of electrodes on the skin surface y nmes activates motor neurons resulting in the simultaneous contraction of many motor units. Advantages: y non-invasive! y easy to reuse surface electrodes y east to apply and remove. Disadvantages: y not everyone can use nmes y recruitment of muscle fibres y. Lack of recruitment specificity y high energy required y shave stimulated surfaces. Risks: y burning of the skin y fractures of long bone head of femur y y y may trigger autonomic dysreflexia. Not everyone can use nmes y with injuries below t12 l1 usually the axon (pathway) of the motor neuron is damaged y the motor neuron is no longer intact. The danger of autonomic dysreflexia y the dangers might matter more! Boosting y purposeful induction of autonomic dysreflexia to enhance performance. Burnham studied boosting and found the following results y boosting improved racing time by 10%
