Effect of long-term neck muscle training on pressure pain threshold: a randomized controlled trial.

Muscle tenderness has been measured in several studies to evaluate effectiveness of treatment methods, but only short-term results have been reported so far. The aim of the present study was to evaluate the long-term effects of two different muscle training methods on the pressure pain threshold of neck muscles in women with neck pain. Altogether 180 woman with chronic, non-specific neck pain were randomized into three groups: neck muscle endurance training, neck muscle strength training and control groups. The main outcome measures included pressure pain threshold measurement at six muscle sites and on the sternum. Neck pain was assessed by a visual analogue scale (VAS). At the 12-month follow-up statistically significantly higher pressure pain threshold values were obtained in both training groups at all muscle sites compared to the baseline, while no significant change occurred in the controls. Significantly higher changes in pressure pain threshold were detected at all six sites in the strength training group and at four out of six sites in the endurance training group compared to the control group. This is the first study to show an increase in pressure pain thresholds as a result of long-term muscle training. A decrease in neck pain was associated with reduced pressure pain sensitivity in neck muscles, showing that the pressure pain threshold may be a useful outcome measure of the effectiveness of neck muscle rehabilitation.

Mini-intervention for subacute low back pain: two-year follow-up and modifiers of effectiveness.

STUDY DESIGN: Randomized controlled trial. OBJECTIVES: To Investigate the long-term effectiveness, costs, and effect modifiers of a mini-intervention, provided in addition to the usual care, and the incremental effect of a worksite visit for patients with subacute disabling low back pain (LBP). SUMMARY OF BACKGROUND DATA: A mini-intervention was earlier proved to be an effective treatment for subacute LBP. Whether the beneficial effect is sustained is not known. Furthermore, modifiers of a treatment effect are largely unknown. METHODS: A total of 164 patients with subacute LBP randomized into a mini-intervention (A, n = 56), a mini-intervention plus a worksite visit (B, n = 51), or the usual care (C, n = 57). Mini-intervention consisted of a detailed assessment of the patients' history, beliefs, and physical findings by a physician and a physiotherapist, followed by recommendations and advice. The usual care patients received the conventional care. Pain, disability, health-related quality of life, satisfaction with care, days on sick leave, and health care consumption and costs were measured during a 24-month follow-up. Thirteen candidate modifiers were tested for each outcome. RESULTS: There were no differences between the three treatment arms regarding the intensity of pain, the perceived disability, or the health-related quality of life. However, mini-intervention decreased occurrence of daily (A vs., C, P = 0.01) and bothersome (A vs. C, P < 0.05) pain and increased treatment satisfaction. Costs resulting from LBP were lower in the intervention groups (A 4670 Euros, B 5990 Euros) than in C (C 9510 Euros) (A vs. C, P = 0.04; and B vs. C, not significant). The average number of days on sick leave was 30 in A, 45 in B, and 62 in C (A vs. C, P = 0.03; B vs. C, not significant). The perceived risk for not recovering was the strongest modifier of treatment effect. Mental and mental-physical workers in A and B were less often on sick leave than those in C. CONCLUSIONS: Mini-intervention is an effective treatment for subacute LBP. Despite lack of a significant effect on intensity of low back pain and perceived disability, mini-intervention, including proper recommendations and advice, according to the "active approach," is able to reduce LBP-related costs. The perceived risk of not recovering was the strongest modifier of treatment effect. In alleviating pain, the intervention was most effective among the patients with a high perceived risk of not recovering.

Association of neck pain, disability and neck pain during maximal effort with neck muscle strength and range of movement in women with chronic non-specific neck pain.

Several studies have reported lower neck muscle strength in patients with chronic neck pain compared to healthy controls. The aim of the present study was to evaluate the association between the severity of neck pain and disability with neck strength and range of movement in women suffering from chronic neck pain. One hundred and seventy-nine female office workers with chronic neck pain were selected to the study. The outcome was assessed by the self-rating questionnaires on neck pain (visual analogue scale, Vernon's disability index, Neck pain and disability index) and by measures of the passive range of movement (ROM) and maximal isometric neck muscle strength. No statistically significant correlation was found between perceived neck pain and the disability indices and the maximal isometric neck strength and ROM measures. However, the pain values reported during the strength tests were inversely correlated with the results of strength tests (r=-0.24 to -0.46), showing that pain was associated with decreased force production. About two-thirds of the patients felt pain during test efforts. Pain may prevent full effort during strength tests and hence the production of maximal force. Thus in patients with chronic neck pain the results do not always describe true maximal strength, but rather the patients' ability to bear strain, which may be considerably influenced by their painful condition. The results of the present study suggest that rehabilitation in cases of chronic neck pain should aim at raising tolerance to mechanical strain.

Outcome determinants of subacute low back pain.

STUDY DESIGN: Descriptive prognostic study. OBJECTIVES: To identify outcome determinants of subacute low back pain. SUMMARY OF BACKGROUND DATA: The factors predicting recovery from prolonged back pain among working adults are largely unknown. MATERIALS AND METHODS: One hundred sixty-four employed patients with subacute (duration of pain 4-12 weeks) daily low back pain were recruited from primary health care to a randomized study. Data on potential predictive factors were collected before randomization. In multiple regressions using repeated measures analysis, the treatment received was adjusted when determining the impact of the predictive factors. Dependent outcome variables used were pain, perceived functional disability, generic health-related quality of life, satisfaction with care, days on sick leave, use of health care, and costs of health care consumption measured, at 3-, 6-, and 12-month follow-ups. RESULTS: Age and intensity of pain at baseline predicted most of the outcomes. The perceived risk of not recovering was a stronger determinant of outcome than gender, education, or self-rated health status (which did not have any predictive value) or body mass index, expectations of treatment effect, satisfaction with work, or the presence of radicular symptoms below the knee (only slight predictive value). The only factors predicting the duration of sick leave were the duration of sick leave at baseline and the type of occupation. CONCLUSION: Age and intensity of pain are the strongest predictors of outcome. Accumulation of days on sick leave is predicted by the duration of sick leave at entry and the type of work, but not by pain, perceived disability, or satisfaction with work.

Active neck muscle training in the treatment of chronic neck pain in women: a randomized controlled trial.

CONTEXT: Active physical training is commonly recommended for patients with chronic neck pain; however, its efficacy has not been demonstrated in randomized studies. OBJECTIVE: To evaluate the efficacy of intensive isometric neck strength training and lighter endurance training of neck muscles on pain and disability in women with chronic, nonspecific neck pain. DESIGN: Examiner-blinded randomized controlled trial conducted between February 2000 and March 2002. SETTING: Participants were recruited from occupational health care systems in southern and eastern Finland. PATIENTS: A total of 180 female office workers between the ages of 25 and 53 years with chronic, nonspecific neck pain. INTERVENTIONS: Patients were randomly assigned to either 2 training groups or to a control group, with 60 patients in each group. The endurance training group performed dynamic neck exercises, which included lifting the head up from the supine and prone positions. The strength training group performed high-intensity isometric neck strengthening and stabilization exercises with an elastic band. Both training groups performed dynamic exercises for the shoulders and upper extremities with dumbbells. All groups were advised to do aerobic and stretching exercises regularly 3 times a week. MAIN OUTCOME MEASURES: Neck pain and disability were assessed by a visual analog scale, the neck and shoulder pain and disability index, and the Vernon neck disability index. Intermediate outcome measures included mood assessed by a short depression inventory and by maximal isometric neck strength and range of motion measures. RESULTS: At the 12-month follow-up visit, both neck pain and disability had decreased in both training groups compared with the control group (P<.001). Maximal isometric neck strength had improved flexion by 110%, rotation by 76%, and extension by 69% in the strength training group. The respective improvements in the endurance training group were 28%, 29%, and 16% and in the control group were 10%, 10%, and 7%. Range of motion had also improved statistically significantly in both training groups compared with the control group in rotation, but only the strength training group had statistically significant improvements in lateral flexion and in flexion and extension. CONCLUSIONS: Both strength and endurance training for 12 months were effective methods for decreasing pain and disability in women with chronic, nonspecific neck pain. Stretching and fitness training are commonly advised for patients with chronic neck pain, but stretching and aerobic exercising alone proved to be a much less effective form of training than strength training.

Mini-intervention for subacute low back pain: a randomized controlled trial.

STUDY DESIGN: Randomized controlled trial. OBJECTIVES: To investigate the effectiveness and costs of a mini-intervention, provided in addition to the usual care, and the incremental effect of a work site visit for patients with subacute disabling low back pain. SUMMARY OF BACKGROUND DATA: There is lack of data on cost-effectiveness of brief interventions for patients with prolonged low back pain. METHODS: A total of 164 patients with subacute low back pain were randomized to a mini-intervention group (A), a work site visit group (B), or a usual care group (C). Groups A (n = 56) and B (n = 51) underwent one assessment by a physician plus a physiotherapist. Group B received a work site visit in addition. Group C served as controls (n = 57) and was treated in municipal primary health care. All patients received a leaflet on back pain. Pain, disability, specific and generic health-related quality of life, satisfaction with care, days on sick leave, and use and costs of health care consumption were measured at 3-, 6-, and 12-month follow-ups. RESULTS: During follow-up, fewer subjects had daily pain in Groups A and B than in Group C (Group A Group C, = 0.002; Group B Group C, = 0.030). In Group A, pain was less bothersome (Group A Group C, = 0.032) and interfered less with daily life (Group A Group C, = 0.040) than among controls. Average days on sick leave were 19 in Group A, 28 in Group B, and 41 in Group C (Group A Group C, = 0.019). Treatment satisfaction was better in the intervention groups than among the controls, and costs were lowest in the mini-intervention group. CONCLUSIONS: Mini-intervention reduced daily back pain symptoms and sickness absence, improved adaptation to pain and patient satisfaction among patients with subacute low back pain, without increasing health care costs. A work site visit did not increase effectiveness.
