Summary

The purpose of this study is to determine whether placement of stimulating electrodes over the ulnar nerve is important for proper delivery of current leading to stimulation of intrinsic hand muscles.

Conditions

  • Ulnar Nerve

Interventions

OTHER

Hand measurements

Ulnar right: * Width of wrist * Distance from radial side to middle of ulnar groove * Photo of ulnar groove o Grade ability to identify: easy, moderate-difficult, unable * Ultrasound measurements Ulnar left: * Width of wrist * Distance from radial side to middle of ulnar groove * Photo of ulnar groove o Grade ability to identify: easy, moderate-difficult, unable * Ultrasound measurements

OTHER

Foot/ankle measurements

Posterior tibial right: * Distance between prominence of medial malleolus and mid-Achilles tendon * Distance artery point of maximal pulsation to posterior border of medial malleolus * Distance artery point of maximal pulsation to medial border of Achilles tendon * Photo taken after palpating posterior tibial artery o Grade ability to identify: easy, moderate-difficult, unable * Ultrasound measurements Posterior tibial left: * Distance between prominence of medial malleolus and mid-Achilles tendon * Distance artery point of maximal pulsation to posterior border of medial malleolus * Distance artery point of maximal pulsation to medial border of Achilles tendon * Photo taken after palpating posterior tibial artery o Grade ability to identify: easy, moderate-difficult, unable * Ultrasound measurements
