Randomized Controlled Trial Comparative Study Clinical Trial
Active therapy for chronic low back pain part 1. Effects on back muscle activation, fatigability, and strength.
Randomized prospective study of the effects of three types of active therapy on back muscle function in chronic low back pain patients. ⋯ Significant changes in muscle performance were observed in all three active therapy groups post-therapy, which appeared to be mainly due to changes in neural activation of the lumbar muscles and psychological changes concerning, for example, motivation or pain tolerance.

Randomized Controlled Trial Clinical Trial
Active therapy for chronic low back pain: part 2. Effects on paraspinal muscle cross-sectional area, fiber type size, and distribution.
Randomized prospective study to compare the effects of three types of active therapy on the back muscle structure of chronic low back pain patients. ⋯ Three months active therapy is not sufficient to reverse the typical "glycolytic" profile of the muscles of cLBP patients or to effect major changes in backmuscle size. The alterations in muscle performance observed (increased strength and endurance; Part 1) werenot explainable on the basis of structural changes within the muscle.

Randomized Controlled Trial Clinical Trial
A randomized clinical trial of exercise and spinal manipulation for patients with chronic neck pain.
A randomized, parallel-group, single-blinded clinical trial was performed. After a 1-week baseline period, patients were randomized to 11 weeks of therapy, with posttreatment follow-up assessment 3, 6, and 12 months later. ⋯ For chronic neck pain, the use of strengthening exercise, whether in combination with spinal manipulation or in the form of a high-technology MedX program, appears to be more beneficial to patients with chronic neck pain than the use of spinal manipulation alone. The effect of low-technology exercise or spinal manipulative therapy alone, as compared with no treatment or placebo, and the optimal dose and relative cost effectiveness of these therapies, need to be evaluated in future studies.

Randomized Controlled Trial Clinical Trial
The impact of physical function and pain on work status at 1-year follow-up in patients with back pain.
A randomized, controlled trial. ⋯ Return to work was related to physical function and pain. More importance seemed to be attributed to physical performance in the intervention group than in the controls as a basis for returning patients to work.

Randomized Controlled Trial Clinical Trial
Prospective randomization of parenteral hyperalimentation for long fusions with spinal deformity: its effect on complications and recovery from postoperative malnutrition.
A prospective randomized study of total parenteral nutrition for long spinal deformity fusions as well as its effect on complications and recovery from postoperative malnutrition was performed. ⋯ The administration of postoperative total parenteral nutrition to patients with spinal deformity is safe. No statistical reduction in complications occurred in the total parenteral nutrition group despite a trend toward more rapid normalization of nutritional parameters and a decrease in postoperative nutritional depletion. The anterior/posterior-staged group with the administration of total parenteral nutrition had a lower overall complication rate and a decreased incidence of postoperative nutritional depletion than the one-stage reconstruction group. The difference in the complication rates between the two groups may relate as much to the staging as to the administration of total parenteral nutrition per se. For certain cases it may be more advisable to stage patients and deliver total parenteral nutrition than to manage the cases in a continuous (i.e., same-day) fashion.
