Logan Basic Technique Measured by Surface Electromyography (EMG)

The Effect of Logan Basic Technique Apex Contact Adjustment on the Motor Recruitment Pattern in the Erector Spinae.

The purpose of this investigation is to determine the effect of Logan Basic Technique apex contact adjustment (LBT); on the motor recruitment pattern in the erector spinae group via surface EMG.

LBT is a low force adjusting technique that focuses on the foundation segment of the spine, the sacrum, with application of contact on the sacrotuberous ligament which relieves fatigued and strained muscles, particularly intrinsic muscles of the back. Surface electromyography (EMG) is a method of analyzing the activity level of superficial muscles. It is convenient and advantageous when studying muscle relaxation which occurs in biofeedback studies

Inclusion Criteria:

• Students in trimesters 1 - 3.
• Naive to the Logan Basic Technique adjusting protocol.

Exclusion Criteria:

• Students in trimesters 4 - 10.
• Pregnant females or females who can possibly be pregnant.
