A surface EMG diagnostic protocol was developed to assess the neuromuscular/postural contributions to pain states. The EMG activity of the right and left aspects of 11 muscle groups were monitored while the patient was in the sitting and standing positions. The diagnostic protocol was evaluated by comparing the patterns of EMG activity in four diagnostic groups: headache only, neck/shoulder/upper back pain only, low back pain only, and mixed pain states. The results suggest that (1) bilateral… 

Electromyographic activity imbalances between contralateral back muscles: An assessment of measurement properties.

The results showed that back pain subjects did not produce higher coupled moments than controls and providing feedback of the axial rotation moment to correct asymmetric efforts during the task did not reduce EMG contralateral imbalances, except for some extreme cases.

The comparison of trunk muscles EMG activation between subjects with and without chronic low back pain during flexion-extension and lateral bending tasks.

Assessment of lumbar EMG during static and dynamic activity in pain-free normals: Implications for muscle scanning protocols

Clinicians may be better served utilizing local norms when using EMG for classification purposes after it is proposed that in pain-free normals, symmetrical tasks that bend the trunk forward or extend the trunk backward produce symmetrical paraspinal EMG activity.

Pain-Related Fear, Lumbar Flexion, and Dynamic EMG Among Persons With Chronic Musculoskeletal Low Back Pain

The relationship between pain-related fear and EMG during flexion and extension appears to be mediated by reduced lumbar flexion, and these musculoskeletal abnormalities as well as limited movement may be involved in the development and maintenance of chronic low back pain.

EMG scanning: Normative data

The data show that females tend to muscle brace more than males in the upper extremities in the higher extremities and interactions among sex, position, and side for various measures on the trapezius are revealed.

The use of EMG feedback and progressive relaxation in the treatment of a woman with chronic back pain

A 71-year-old white female with chronic back pain and paravertebral muscle spasm was treated with 17 sessions of electromyographic feedback, with recording site just below the right inferior scapular angle.

Treating Chronic Low Back Pain

A patient with chronic back pain was selected in order to study the effects of EMG biofeedback training to his low back musculature during stationary positions (standing and sitting) and trunk movements.

The effectiveness of EMG biofeedback training in low back pain

Pain scores of patients with high pain decrements during training showed further improvement during follow-up, which was not the case with patients showing less substantial improvement, but the importance of cognitions was discussed.

SYMPTOMS OF ANXIETY AND TENSION AND THE ACCOMPANYING PHYSIOLOGICAL CHANGES IN THE MUSCULAR SYSTEM

The hypotheses were that an increase in innervation of the skeletal muscles accompanies anxiety so that in anxious patients attempting to relax not only will muscle tension be greater than in healthy subjects, but those patients with most clinical evidence of anxiety and " tension" will have the most muscle tension.

Electromyography of deep back muscles in man.

The experimental evidence confirms the anatomical hypothesis that the multifidi are stabilizers rather than prime movers of the whole vertebral column, and suggests that the transversospinal muscles adjust the motion between individual vertebrae.

EMG Biofeedback and Tension Headache: A Controlled Outcome Study

A three‐month follow-up questionnaire revealed a greatly decreased medication usage in the experimental group, and a pseudofeedback control group and a no‐treatment control group failed to show significant reductions.
