Continuation of group physical therapy is necessary in ankylosing spondylitis: results of a randomized controlled trial.

PURPOSE: Group physical therapy in patients with ankylosing spondylitis was studied to determine whether beneficial effects persisted after cessation of the intervention. METHODS: After a 9-month period of supervised group physical therapy, 68 patients were randomized for another 9 months to unsupervised daily exercises at home (discontinuation group) or continuation of weekly sessions of supervised group physical therapy (continuation group). Endpoints were spinal mobility (thoraco-lumbar flexion and extension, chest expansion, cervical rotation), fitness (maximum work capacity), functioning (Sickness Impact Profile (SIP), Health Assessment Questionnaire for the Spondylarthropathies [HAQ-S], Functional Index [FI]), and patient's global health assessment on a visual analogue scale. RESULTS: Time for exercises at home was significantly higher in the continuation than in the discontinuation group (mean duration 1.9 versus 1.2 hr per week, P < 0.05). The continuation group improved in global health (mean improvement 1.6; 32%) and in SIP score. Scores for thoraco-lumbar mobility and HAQ-S did not change very much, whereas chest expansion, cervical rotation, fitness, and FI deteriorated. The average attendance for group therapy sessions was 62%. The discontinuation group improved only marginally (0.2; 4%) in global health, whereas all other endpoints decreased. Only for global health and HAQ-S were the differences statistically significant in favor of the continuation group. CONCLUSIONS: Global health and functioning are sustained or even improved further if group physical therapy is continued. Spinal mobility decreased slightly in both groups.

Is group physical therapy superior to individualized therapy in ankylosing spondylitis? A randomized controlled trial.

PURPOSE: To study the effects of adding supervised group physical therapy to unsupervised individualized therapy in ankylosing spondylitis. METHODS: One hundred forty-four patients were randomized to exercises at home, or the same plus weekly group physical therapy for 9 months. Endpoints were spinal mobility, fitness (maximum work capacity by ergometry), functioning (Sickness Impact Profile, Health Assessment Questionnaire for the Spondylarthropathies, and Functional Index), and patient's global assessment of change on a 10-cm visual analogue scale. RESULTS: Thoracolumbar flexion and extension increased by an average of 0.5 cm (9%) after home exercises, and by 0.9 cm (16%) after group therapy. Maximum load in ergometry decreased by 2 W (1%) after home exercises, but increased by 7 W (4%) after group therapy. Global assessment improved by 0.3 (6%) after home exercises, and by 1.7 (34%) after group therapy. These three differences were statistically significant. There were no significant differences in chest expansion, cervical rotation, or the self-assessments of functioning. CONCLUSIONS: Group physical therapy proved superior to individualized therapy in improving thoracolumbar mobility and fitness, and had an important effect on global health reported by the patients.
