“…Table S1 also shows ratings of homogeneity between the identified NEPs of a muscle. The outcomes of the systematic comparison between current NEP findings and the MPs previously obtained by NMES are summarized in Table S2 (Supplementary Material).…”

“…In cases where the relative position on the x‐ and y‐axes had an SD of >6%, the homogeneity was defined as “poor,” whereas the ratings “fair” and “good” corresponded to SDs of 4%−6% and <4%, respectively. The F ‐test with Bonferroni correction was used to evaluate whether the defined positions of the NEPs within 1 specific muscle differed from each other or from the corresponding MPs detected by NMES in our previous study with students . Because only 1 NEP was observed for Pmin, a t ‐test was applied to test the differences between the data collected from the present study and the data from our previous study.…”

“…The primary purpose of this study was to localize NEPs of 5 superficial upper body muscles by dissection of human cadavers and, subsequently, to compare them with previously identified functional MPs using an anatomical landmark−based mapping technique . We also aimed to identify possible interindividual variations in NEP locations and compare them with the MP locations.…”

Objectives This study was performed to compare the electrical methods of motor points mapping using surface EMG and electric probe (Pointer Excel II). Methods 32 healthy adults (male 16, female 16) were selected. and classified into two groups; surface EMG group, electric probe (Pointer Excel II) group. In surface EMG group, motor points were searched by recoding the compound muscle potentials. In electric probe (Pointer Excel II) group, motor points were searched by scanning the skin with Pointer Excel II at low level stimulation. The locations of the motor points were expressed as X and Y values in relation to the reference line. The horizontal reference line was set as elbow crease and the vertical reference line was set as the line connecting coracoid process to the center of the horizontal reference line. The data was analyzed by 'Independent T-test' and 'equivalence test'. Results 1. The motor points of short head and long head of biceps brachii muscle were located at about 2/3 length of the vertical reference line from coracoid process and about 1/5∼1/4 length of the half of the horizontal reference line from the vertical reference line in both group. 2. The motor points of the short head were located more distally and close to the vertical reference line (p＜0.001). 3. In surface EMG group, the motor points of the long head were located more laterally in the female than male. And the motor points of the long head were located more distally in the left side than right side (p＜0.05). In electric probe (Pointer Excel II) group, similar tendency was observed but there was no statistically significant difference (p＞0.05). 4. As a result of the equivalence test between surface EMG group and electric probe (Pointer Excel II) group, the confidence intervals of the difference were within the equivalence limit. Therefore, the locations of the motor points searched by two ways are equa l (p＞0.05, equivalence interval=3%). Conclusions The results indicate that electric probe (Pointer Excel II) can be used to search the motor points instead of surface EMG. This might improve the clinical efficiency when using the motor points to treat muscle dysfunction. (J Korean Med Rehabil 2018;28(1):85-96)
