The prescription of exercise as a conservative treatment for lumbar pain is frequent and seems effective for the chronic cases of nonspecific low back pain. However, there is no evidence favoring one type of exercise over another. Often, exercise programs are prescribed without adequate evaluation of the individual characteristics like posture, muscular force, and extensibility. Patients with totally different causes of low back pain will often be given the same type of exercises.
                Our objective was to compare the effectiveness of 2 home exercise programs in decreasing disability and pain related to subacute and chronic nonspecific low back pain. To do so we compared a specific (individualized) exercise program with a program of commonly prescribed exercises for low back pain.
                In a control group study, 20 patients with chronic or subacute nonspecific low back pain participated after giving their informed consent. All subjects were evaluated (physical evaluation of lumbar and pelvic muscles [1] force and [2] extensibility, [3] trunk range of motion) and then divided in 2 groups: 10 patients received specific exercises (experimental group) based on their evaluation, and 10 patients received a commonly prescribed exercise program for low back pain (control group). Six weeks later a second physical evaluation was conducted. Pain (visual analog pain scale) and disability (modified Oswestry) questionnaires were also completed by each subject at both evaluations.
                This was a randomized experimental study.
                Both groups had similar age, weight, and sex characteristics. The experimental group showed significant improvements for some components targeted by the program. The control group significantly had improvement of some physical characteristics not related to their initial deficits. Even if both groups showed some improvements in muscular force and extensibility, only the members of the group who received specific exercises significantly reduced their level of pain and disability. Both groups showed a similar rate of participation in the program.
                The results of this study suggest that applying a specific physical evaluation and exercise prescription is an appropriate treatment for people having subacute or chronic nonspecific pain. Thus clinicians should prescribe exercise programs based on individual muscular deficits rather than most commonly prescribed exercise programs. Patients with nonspecific mechanical low back pain (n = 103), examined by an orthopaedic surgeon and a social worker, were randomized to an activity group (n = 51) and a control group (n = 52). Patients with defined orthopaedic, medical, or psychiatric diagnoses were excluded before randomization. No patients were excluded due to place of birth or difficulties in speaking or understanding the Swedish language. The purpose of the study was to compare mobility, strength and fitness after traditional care and after traditional care plus a graded activity program with a behavioral therapy approach. A graded activity program, with a behavioral therapy approach was given under the guidance of a physical therapist. The endpoint of the graded activity program was return to work. This program significantly increased mobility, strength, and fitness more than could be explained by only a time recovery effect, especially in males. The patients in the activity group returned to work earlier than did the patients in the control group. Spinal rotation, abdominal muscle endurance time and lifting capacity were significantly correlated to rate of return to work. Traditional care plus a graded activity program were superior to only traditional care, evaluated in terms of mobility, strength and fitness. The graded activity program proved to be a successful method of restoring occupational function and facilitating return to work in subacute low back pain patients. The patients in the graded activity program learned that it is safe to move, while regaining function. To evaluate the short-term effect of physical exercise and a cognitive intervention in low back pain.
                Randomized controlled trial.
                Ninety-three patients sick-listed for 8-12 weeks for sub-acute low back pain were randomized to an exercise regime (n = 30), a cognitive intervention (n = 34) or a control group (n = 29).
                Primary outcome measures were pain, disability, sick-listing and satisfaction with care. Secondary outcome measures were self-efficacy for pain and for function, fear-avoidance beliefs, emotional distress, generic health status and life satisfaction.
                Eighteen percent of subjects dropped out. Drop-out was most frequent in the exercise group. At 18 weeks after inclusion fear-avoidance beliefs were reduced in both intervention groups. The cognitive group demonstrated significant improvement in disability, self-efficacy for pain, emotional distress, general health and life satisfaction. Patients in the exercise group were significantly more satisfied with the treatment, and patients following the exercise protocol reduced pain significantly. No effect on sick-listing was seen.
                Cognitive intervention improved disability and may be feasible for most patients sick-listed in the sub-acute phase. Physical exercise reduced patients' symptoms, but requires high motivation by patients. Despite positive effects in intervention groups on variables considered as negative prognostic factors for long-term disability and sickness absence, interventions had no effect on sick-listing. This article examines the effectiveness of manual therapy with specific adjuvant exercise for treating chronic low back pain and disability.
                A single blind, randomized, controlled trial was employed. Patients were prescribed an exercise program that was tailored to treat their musculoskeletal dysfunctions or given a nonspecific program of general stretching and aerobic conditioning. In addition, patients received manual therapy or sham manual therapy. Participants were seen for 6 weekly sessions and were asked to perform their exercise program twice daily.
                Seventy-two out of 100 patients completed the study. Multivariate tests conducted for measures of pain and disability revealed a significant group by time interaction (P = 0.04 and P = 0.05, respectively), indicating differential change in these measures pretreatment to posttreatment as a function of the treatment received. When controlling for pretreatment scores, patients receiving manual therapy with specific adjuvant exercise reported significant reductions in pain. No change in perceived disability was observed, with the exception that patients receiving sham manual therapy with specific adjuvant exercise reported significantly greater disability at posttreatment.
                Manual therapy with specific adjuvant exercise appears to be beneficial in treating chronic low back pain. Despite changes in pain, perceived function did not improve. It is possible that impacting chronic low back pain alone does not address psychosocial or other factors that may contribute to disability. Further studies are needed to examine the long-term effects of these interventions and to address what adjuncts are beneficial in improving function in this population. Low back pain is a common medical and social problem frequently associated with disability and absence from work. However, data on effective return to work after interventions for low back pain are scarce.
                To determine the effectiveness of a behavior-oriented graded activity program compared with usual care.
                Randomized, controlled trial.
                Occupational health services department of an airline company in the Netherlands.
                134 workers who were absent from work because of low back pain were randomly assigned to either graded activity (n = 67) or usual care (n = 67).
                Graded activity, a physical exercise program based on operant-conditioning behavioral principles, to stimulate a rapid return to work.
                Outcomes were the number of days of absence from work because of low back pain, functional status (Roland Disability Questionnaire), and severity of pain (11-point numerical scale).
                The median number of days of absence from work over 6 months of follow-up was 58 days in the graded activity group and 87 days in the usual care group. From randomization onward, graded activity was effective after 50 days of absence from work (hazard ratio, 1.9 [95% CI, 1.2 to 3.2]; P = 0.009). The graded activity group was more effective in improving functional status and pain than the usual care group. The effects, however, were small and not statistically significant.
                Graded activity was more effective than usual care in reducing the number of days of absence from work because of low back pain. To compare the short-term outcomes of active individual therapy (AIT) with those of a functional restoration program (FRP).
                Prospective randomized controlled study.
                Two rehabilitation centers and private ambulatory physiotherapy facilities.
                One hundred thirty-two adults with chronic low back pain. Fifty-one percent of patients on sick leave or out of work (mean duration, 180d in the 2y before treatment).
                For 5 weeks, FRP (at 25h/wk) or AIT (at 3h/wk).
                Trunk flexibility, back flexor, and extensor endurance (Ito and Sorensen tests), general endurance, pain intensity, Dallas Pain Questionnaire (DPQ) scores, daily activities, anxiety depression, social interest, and work and leisure activities, and self-reported improvement (work ability, resumption of sport and leisure activities).
                All outcome measures improved after treatment except endurance in AIT. There was no between-group difference for pain intensity or DPQ daily activities or work and leisure activities scores. Better results were observed in FRP for all other outcome measures. There was a significant effect of treatment and the initial value for the gain of the Sorensen score with a treatment or initial value interaction; a significant effect of treatment and initial value on the gains of Ito, endurance, and DPQ social interest and anxiety depression scores, with no treatment or initial value interaction; and a significant effect of initial value but not treatment for the gains of DPQ daily activities and work and leisure activities scores.
                Low-cost ambulatory AIT is effective. The main advantage of FRP is improved endurance. We speculate that this may be linked to better self-reported work ability and more frequent resumption of sports and leisure activities. To evaluate effectiveness of an exercise programme in a community setting for patients with low back pain to encourage a return to normal activities.
                Randomised controlled trial of progressive exercise programme compared with usual primary care management. Patients' preferences for type of management were elicited independently of randomisation.
                187 patients aged 18-60 years with mechanical low back pain of 4 weeks to 6 months' duration.
                Exercise classes led by a physiotherapist that included strengthening exercises for all main muscle groups, stretching exercises, relaxation session, and brief education on back care. A cognitive-behavioural approach was used.
                Assessments of debilitating effects of back pain before and after intervention and at 6 months and 1 year later. Measures included Roland disability questionnaire, Aberdeen back pain scale, pain diaries, and use of healthcare services.
                At 6 weeks after randomisation, the intervention group improved marginally more than the control group on the disability questionnaire and reported less distressing pain. At 6 months and 1 year, the intervention group showed significantly greater improvement in the disability questionnaire score (mean difference in changes 1.35, 95% confidence interval 0.13 to 2.57). At 1 year, the intervention group also showed significantly greater improvement in the Aberdeen back pain scale (4.44, 1.01 to 7.87) and reported only 378 days off work compared with 607 in the control group. The intervention group used fewer healthcare resources. Outcome was not influenced by patients' preferences.
                The exercise class was more clinically effective than traditional general practitioner management, regardless of patient preference, and was cost effective. To assess the efficacy of exercise therapy for acute low back pain, a randomized, placebo-controlled trial was performed in 40 Dutch general practices. Patients received either exercise instruction with advice for daily life by a physiotherapist; placebo ultrasound therapy by a physiotherapist; or usual care by the general practitioner. All patients received analgesic agents and information on low back pain before randomization. Four hundred seventy-three patients were included. No differences in number of recurrences, functional health status, or medical care usage could be found among the three groups. In the exercise group, duration of recurrences was shorter and patients were less tired during the first 3 months than in the usual care group, but no differences were found between the exercise and placebo groups. It was concluded that exercise therapy for patients with acute low back pain has no advantage over usual care from the general practitioner. Back extension exercises are commonly recommended to treat acute low back pain. Evidence of their beneficial effect is, however, weak.
                We aimed to demonstrate a benefit of teaching back extension exercises in addition to usual GP care for acute low back pain.
                Patients with acute simple low back pain of less than 28 days duration, presenting to a GP, were randomized either to attend a back class or to receive conventional management. Outcome was measured using changes in the Oswestry disability score and visual analogue pain scale (VAS) on six occasions during 1 year and also a VAS and patient assessment of degree of disability during the previous 6 months at 1 year.
                Seventy-five patients were recruited. The principal outcome measures showed no difference between the two groups. The treatment group reported less chronic disability at 1 year (50% versus 14%, P < 0.007).
                A treatment effect has not been demonstrated, but some patients who would otherwise have reported mild pain were pain free after 1 year. This approach to treating back pain has not been shown to be effective. More much larger studies, with more intensive treatment, are required in order to decide whether physical therapy in primary care is beneficial as treatment for acute back pain.
Exercise therapy appears to be slightly effective at decreasing pain and improving function in adults with chronic low-back pain, particularly in healthcare populations. In subacute low-back pain there is some evidence that a graded activity program improves absenteeism outcomes, though evidence for other types of exercise is unclear. In acute low-back pain, exercise therapy is as effective as either no treatment or other conservative treatments.
