A controlled study on the outcome of inpatient and outpatient treatment of low back pain. Part II. Effects on physical measurements three months after treatment.

Inpatient and outpatient treatments were compared with a control intervention in 288 men and 168 women, aged 35-54, who were at work, but suffered from chronic or recurrent low back pain. Physical measurements and back pain assessments were carried out before the intervention and at a 3-month follow-up. Physical fitness improved most in the inpatients, but the outpatients did not differ from the controls. Correlations between back pain and physical measurements indicated that increase of lumbar and hip mobility was more important than increase of trunk strength for subjective progress in these patients. Increased trunk extension strength correlated significantly with subjective progress in women, who also had higher correlations between improved physical fitness and progress than men.

Spinal mobility and posture and their correlations with growth velocity in structurally normal boys and girls aged 13 to 14.

Spinal mobility and posture were measured and their correlations with growth velocity were calculated in 30 boys and 30 girls aged 13 to 14. The spinal measurements were carried out by noninvasive goniometric methods. In the thoracic spine kyphosis (P less than 0.01), forward flexion (P less than 0.01) and the sum of lateral flexions (P less than 0.05) were reduced in the girls compared with the boys. In the boys and girls alike, thoracic rotation to the left was smaller than to the right, but the difference was statistically significant (P less than 0.05) only for the girls. In the girls, thoracic forward flexion and rotation to the left had negative correlations (r = -0.38 and -0.39, P less than 0.05) with growth velocity. The hypothetical significance of the results for the explanation of the development of adolescent idiopathic scoliosis is discussed.

Correlations of hip mobility with degree of back pain and lumbar spinal mobility in chronic low-back pain patients.

Mobility of hips and lumbar spine were measured in 301 men and 175 women who were in employment but suffered from chronic or recurrent low-back pain. The degree of low-back pain (LBP) was assessed with a questionnaire. Hip flexion, extension, internal rotation, and hamstring flexibility in the men, and hip flexion and extension in the women had statistically significant negative correlations with LBP. Among the correlations between hip and lumbar spinal mobility, hip flexion and extension with lumbar rotation were strongest.

Correlations of spinal mobility with degree of chronic low back pain after correction for age and anthropometric factors.

Correlations of age, height, weight, lordosis, and kyphosis with noninvasive spinal mobility measurements were studied in 301 men and 175 women, aged 35-55 years, who suffered from chronic or recurrent low back pain (LBP). Correlations of the different spinal movements with the degree of LBP were analyzed, with corrections for these relationships. Age had significant indirect correlations with most of the mobility measurements, but the effect of height was minor. Weight had considerable negative correlations with the mobility measurements, except lateral flexion. Lordosis and kyphosis had significant relationships with mobility in the sagittal and frontal planes. Correction for the factors analyzed only slightly reduced the correlations between spinal mobility and LPB. Thoracolumbar mobility had higher correlations with LBP than mobility of the lumbar spine. Thoracal spinal mobility alone also correlated with LBP. Lateral flexion and rotation, except for rotation in women, had stronger relationships than forward flexion and extension with LBP.

Lung function in relation to thoracic spinal mobility and kyphosis.

Mobility and kyphosis of the thoracic spine were correlated with lung function in 185 men and 87 women not suffering from respiratory disease. Curvatures of the spine were measured goniometrically with inclinometers and a compass, and lung function by spirometry. Vital capacity and forced expiratory volume in 1 sec had significant positive correlations only with forward and lateral flexion. The strongest correlations were with forward flexion (r = 0.16 to 0.24, p less than 0.05). The results and possible advantages of mobilizing the thoracic spine in pathological conditions of the lungs and the spine are discussed.

Chronic low back pain in men 54-63 years of age. Correlations of physical measurements with the degree of trouble and progress after treatment.

Conservative treatment for chronic low back pain was given to 151 men aged 54-63 years. Pretreatment back trouble and progress were assessed by subjective ratings in questionnaires before the treatment and at 2-, 6- and 12-month follow-up examinations. Physical measurements were made before the treatment and at the 2-month follow-up. Pretreatment low back trouble correlated significantly and positively with lumbar disc degeneration and negatively with spinal lateral flexion and rotation, hip flexion and extension, capacity for dynamic exercises, trunk isometric extension and flexion strength, and intraindividual trunk extension/flexion strength ratio. Progress was significantly associated with follow-up increases of spinal lateral flexion and rotation, hip flexion and lateral rotation, and trunk extension and flexion strength. Combinations of variables did not substantially improve their correlative power as indicators of low back trouble and progress.

Physical therapy for chronic low back pain: correlations between spinal mobility and treatment outcome.

Chronic low back pain in 151 men aged 54 to 63 years was treated for three weeks in a rehabilitation centre or as outpatients at a health centre. Spinal mobility of forward and lateral flexion, and rotation, were measured before and two months after treatment. The effects of the treatment on low back pain were recorded from questionnaires answered before and 2, 6 and 12 months after treatment. A favourable outcome correlated significantly with an increase of spinal lateral flexion (p less than 0.01) and rotation (p less than 0.05). The hypothetical utility of mobilizing lateral flexion and rotation exercises as part of the rehabilitation of patients with chronic low back pain is discussed.

Treatment of patients with chronic low back pain. Comparison between rehabilitation centre and outpatient care.

The results of three weeks' treatment for low back pain were studied in 88 patients at a rehabilitation centre and in 63 outpatients. All the patients were male, and between 54 and 63 years of age. Physical measurements of spinal function were made before and two months after treatment; a questionnaire on back-pain symptoms was filled in before treatment and 2, 6 and 12 months after treatment. A back-pain index based on the replies to the questionnaires was used for evaluating the effects of the treatment. The average results showed that the effects of the treatment lasted six months but disappeared almost completely within a year. The material studied revealed no substantial difference between the results of the rehabilitation centre and outpatient treatment according to the physical measurements or the pain index.

Method and instrument for noninvasive measurements of thoracolumbar rotation.

An objective method of measuring thoracolumbar vertebral rotation by using a suitable compass attached to an auxiliary tool is described. The jugular notch and xiphisternum are used ventrally and the spinous process on the same horizontal planes is used dorsally as reference points for spinal rotation. The method was tested on 39 adults. The mean of intratester and intertester correlation coefficients for the measurements was 0.79 (SD 0.11), with no essential difference between intratester and intertester reproducibility. The results also showed that the method is of considerable validity and, thus, is a supplement to noninvasive goniometric measurements of thoracolumbar mobility in the sagittal and frontal planes.
