Percutaneous Application of Galvanic Current in Rodents Reverses Signs of Myofascial Trigger Points

Intracellular recordings. After the subcutaneous injection of neostigmine, several electric current protocols have been applied: (a) protocol 1 (4 repetitions of 0.4 mA for 5 seconds), (b) protocol 2 (3 repetitions of 1.5 mA for 5 seconds), and (c) protocol 3 (3 repetitions of 3 mA for 3 seconds). The recordings were made 3 hours and 24 hours after applying the protocols. The values are expressed in events per minute (mean ± SEM). Control = 7 muscles; 66 fibers were recorded in total. Neostigmine = 5 muscles; 45 fibers recorded in total. (neostigmine + protocol 1) = 3 muscle; 39 fibers were recorded in total. (neostigmine + protocol 2) = 4 muscles; 36 fibers were recorded in total. (neostigmine + protocol 3) = 4 muscles; 71 fibers were recorded in total. (neostigmine + protocol 1) = 3 muscles; 40 fibers recorded in total. (neostigmine + protocol 2) = 3 muscles; 36 fibers were recorded in total. (neostigmine + protocol 3) = 3 muscles; 56 fibers were recorded in total. with respect to control values.
