A randomized controlled trial of intra-articular triamcinolone and/or physiotherapy in shoulder capsulitis.

OBJECTIVE: To assess the effectiveness of intra-articular triamcinolone injection and physiotherapy singly or combined in the treatment of adhesive capsulitis of the shoulder. METHODS: Eighty patients with adhesive capsulitis of less than 6 months duration were randomized to one of four groups: Group A, injection of triamcinolone 20 mg and eight sessions of standardized physiotherapy; Group B, injection of triamcinolone 20 mg alone; Group C, placebo injection and eight sessions of standardized physiotherapy; or Group D, placebo injection alone. All subjects were given an identical home exercise programme. Outcome measures were assessed at 6 weeks and 16 weeks. The primary outcome measure was Shoulder Disability Questionnaire (SDQ) score. Secondary outcomes were measurement of pain using a visual analogue scale (VAS), global disability using VAS and range of passive external rotation. A two-way analysis of variance was used to explore the effects of corticosteroid injection and physiotherapy. RESULTS: At 6 weeks, the SDQ had improved significantly more in the groups receiving corticosteroid injection (P = 0.004). Physiotherapy improved passive external rotation at 6 weeks (P = 0.02) and corticosteroid injection improved self-assessment of global disability at 6 weeks (P = 0.04). There was no interaction effect between injection and physiotherapy. At 16 weeks, all groups had improved to a similar degree with respect to all outcome measures. CONCLUSION: Corticosteroid injection is effective in improving shoulder-related disability, and physiotherapy is effective in improving the range of movement in external rotation 6 weeks after treatment.

A randomised study of two training programmes for general practitioners in the techniques of shoulder injection.

OBJECTIVES: To evaluate the impact of two different modes of shoulder injection training on the level of confidence and number of injections performed by general practitioners (GPs) METHODS: Demographic details, and information on referrals for shoulder problems, shoulder joint injection activity, and confidence in the six months before training were obtained for 40 GP principals at baseline. Standardised training in the techniques of shoulder joint injection using rubber mannequins was given to all GPs. Twenty of these GPs were randomly allocated to receive additional training on patients in hospital joint injection clinics. Six months after both forms of training the shoulder injection and referral activities of all GPs were reassessed. RESULTS: Both training groups had comparable demographic characteristics and baseline clinical activity. GPs who had additional training with patients reported a marked increase in their level of confidence in performing shoulder injections and the number performed. The number of shoulder referrals did not differ between the groups CONCLUSION: Training on patients in addition to conventional training on mannequins increased GPs' shoulder injection activity and their level of confidence. Hospital injection clinics may provide a suitable setting in which to train GPs interested in developing their shoulder joint injection skills.
