[Rehabilitation of patients with chronic obstructive lung disease. Are two exercise sessions per week sufficient?].

Several studies of patients with chronic obstructive pulmonary disease (COPD) have shown that pulmonary rehabilitation three to seven times a week improves exercise performance and well being. This study investigates feasibility, effect and economic aspects of a programme consisting of two sessions a week. Twenty-four patients were randomized to rehabilitation and twenty-one to placebo. In an outpatient setting patients were assigned to an eight-week programme of exercise plus education twice a week (Exercise group) or conventional community cares (Placebo group). Seven patients did not complete the rehabilitation. The characteristics of the thirty-eight COPD patients at baseline (mean +/- SD): forced expiratory volume in one second (FEV-1) 1.1 +/- 0.4 L, six-minute walk distance (6MWD) 413 +/- 75 m. Rehabilitation resulted in an insignificant improvement in well being and the 6MWD (29 m ¿95% confidence interval: -8-66 m¿. Rehabilitation session twice a week for eight weeks had no effect in patients with moderate COPD.

Rehabilitation of patients with chronic obstructive pulmonary disease. Exercise twice a week is not sufficient!

Several studies of chronic obstructive pulmonary disease (COPD) have shown that pulmonary rehabilitation, consisting of at least three training sessions a week, improves exercise performance and health status. This study investigates feasibility, effect and economic aspects of a rehabilitation programme consisting of two sessions a week for 8 weeks. Twenty-four patients with moderate COPD were randomized to rehabilitation and 21 to placebo. Patients were assigned to an 8-week programme of exercise plus education (Exercise group) or conventional community care (Placebo group). The rehabilitation program was carried out in a hospital outpatient setting and consisted of 16 h exercise and 13.5 h of education. The exercise group received physiotherapy and education twice a week. Seven patients did not complete the programme. The characteristics of the 38 COPD-patients at baseline were the following: (mean +/- SD) forced expiratory volume in 1 sec (FEV1) 1.1+/-0.4 1 (47% of predicted), 6-min walking distance (6MWD) 413+/-75 m, score of St. George's Respiratory Questionnaire (SGRQ) 44+/-21. Health-status, assessed by SGRQ and The Psychological General Well-being (PGWB) Index, did not improve. Rehabilitation resulted in an insignificant improvement in the 6MWD [29 m (95% confidence interval: -8 -66 m)]. We conclude that a rehabilitation program consisting of exercise and education twice a week for 8 weeks had no effect on exercise performance and well being in patients with moderate COPD.

Exercises for chronic low back pain: a clinical trial.

Different training models are effective for the treatment of chronic low back pain, but no consensus has been found. Earlier studies have emphasized training of spinal mobility and back strength. To evaluate if other physiological parameters, such as coordination, are of equal importance, we performed a randomized trial on 40 consecutive patients with chronic low back pain. Two training models were compared: 1) intensive training of muscle endurance and 2) muscle training, including coordination. In both groups, training was performed 1 hour twice a week for 3 months. Pain score, disability score, and spinal mobility improved in both training groups without differences between the two groups. Only intensive training of muscle endurance improved isokinetic back muscle strength. At study entry, we found a significant correlation between spinal mobility and dysfunction, but after the training, no correlation was found between improvement of spinal mobility or isokinetic back extension strength and improvement of function or pain level. We conclude that coordination training for patients with chronic low back pain is as equally effective as endurance training.

Supervised endurance exercise training compared to home training after first lumbar diskectomy: a clinical trial.

OBJECTIVE: We performed a randomised trial to evaluate if intensive supervised training of the back should be offered to all patients after a first lumbar diskectomy. METHODS: Forty consecutive patients were, after a first lumbar diskectomy, randomly allocated to 2 groups undergoing "supervised training" twice a week for 3 months in an outpatient clinic or "home training" after 2 hours of instruction. RESULTS: The two rehabilitation models both showed a significant effect on spinal mobility, isokinetic trunk flexion strength, isokinetic trunk extension strength and daily function. These improvements were unchanged at follow up 3 months later. The pain score remained unchanged, however, throughout the trial in both groups. No differences in effect between the two rehabilitation models could be found for any of the assessed parameters. Thirteen patients did not complete the trial, including 9 from the supervised endurance trained group, mainly because of increased pain and reprolaps (n = 4). Four patients dropped out of the home trained group, only one because of increased pain. The differences in drop-out rate and training side effects were, however, not statistically significant. CONCLUSION: We conclude that it is not worthwhile to implement 3 months of supervised intensive endurance training as opposed to home training in all cases of first lumbar diskectomy, although a beneficial effect and better compliance might be found for a selected group of such patients.
