MuscleactivationTibialisanterioranatomyMuscleinnervationsElectricalstimulationObjective Percutaneous electrical stimulation of the motor point permits selective activation of a muscle. However, the definition and number of motor points reported for a given muscle varies. Our goal was to address these problems....
Fig. 1. Stimulation (motor point stimulation: MPS and peripheral nerve stimulation: PNS) and recording electrodes for soleus (TA) and tibialis anterior (SOL) EMG. For PNS on the SOL muscle, stimulation was applied on the posterior tibial nerve. The stimulator was triggered via TTL pulses progr...

determine whether the location of the motor point (MP) identified with the gross anatomical method corresponds with that identified with electrical stimulation in the tibialis anterior muscle (TA) in order to test the validity of adopting the nerve entry point as the target for electrical ...
Motor neuron and skeletal muscle tissues are the most vulnerable to ALS [2]. Firstly, NRIP protein expression (indicated by the asterisk) in the gastrocnemius (GAS) muscle, tibialis anterior (TA) muscle, and spinal cord from 56-day-old SOD1 G93A mice and age-matched wildtype (WT) mice...
It is hypothesized that locomotion is achieved by means of rhythm generating networks (central pattern generators) and muscle activation generating networks. This modular organization can be partly identified from the analysis of the muscular activity by
In a separate study a more pronounced loss of motor units, remodeling, and altered firing patterns was shown in the first dorsal interosseous muscle compared to the tibialis anterior muscle, arguing for a length-dependent, neuronal basis for motor dysfunction (Allen et al., 2014a). Although ...
