A blinded, randomized, controlled trial assessing conservative management strategies for frozen shoulder

BACKGROUND: There is little evidence for the optimal form of nonoperative treatment in the management of frozen shoulder. This study assesses the efficacy of current physiotherapy strategies. METHODS: All primary care referrals of frozen shoulder to our physiotherapy department were included during a 12-month period. Of these referrals, 17% met the inclusion criteria for primary idiopathic frozen shoulder. The 75 patients were randomly assigned to 1 of 3 groups: group exercise class, individual physiotherapy, and home exercises alone. A single independent physiotherapist, who was blinded to the treatment groups, made all assessments. Range of motion, Constant score, Oxford Shoulder Score, Short Form 36, and Hospital Anxiety and Disability Scale (HADS) outcome measures were performed at baseline, 6 weeks, 6 months, and 1 year. RESULTS: The exercise class group improved from a mean Constant score of 39.8 at baseline to 71.4 at 6 weeks and 88.1 at 1 year. There was a significant improvement in shoulder symptoms on Oxford and Constant scores (P < .001). This improvement was greater than with individual physiotherapy or home exercises alone (P < .001). The improvement in range of motion was significantly greater in both physiotherapy groups over home exercises (P < .001). HADS scores significantly improved during the course of treatment (P < .001). The improvement in HADS anxiety score was significantly greater in both physiotherapy intervention groups than in home exercises alone. CONCLUSIONS: A hospital-based exercise class can produce a rapid recovery from a frozen shoulder with a minimum number of visits to the hospital and is more effective than individual physiotherapy or a home exercise program

Adult-Age Inflammatory Pain Experience Enhances Long-Term Pain Vigilance in Rats

Background: Previous animal studies have illustrated a modulatory effect of neonatal pain experience on subsequent painrelated behaviors. However, the relationship between chronic pain status in adulthood and future pain perception remains unclear. Methodology/Principal Findings: In the current study, we investigated the effects of inflammatory pain experience on subsequent formalin-evoked pain behaviors and fear conditioning induced by noxious stimulation in adult rats. Our results demonstrated an increase of the second but not the first phase of formalin-induced pain behaviors in animals with a history of inflammatory pain that have recovered. Similarly, rats with persistent pain experience displayed facilitated acquisition and prolonged retention of pain-related conditioning. These effects of prior pain experience on subsequent behavior were prevented by repeated morphine administration at an early stage of inflammatory pain. Conclusions/Significance: These results suggest that chronic pain diseases, if not properly and promptly treated, may have a long-lasting impact on processing and perception of environmental threats. This may increase the susceptibility of patients to subsequent pain-related disorders, even when chronic pain develops in adulthood. These data highlight th

Acute Pain and a Motivational Pathway in Adult Rats: Influence of Early Life Pain Experience

The importance of neonatal experience upon behaviour in later life is increasingly recognised. The overlap between pain and reward pathways led us to hypothesise that neonatal pain experience influences reward-related pathways and behaviours in adulthood

Bispectral index-guided management of anaesthesia in permanent vegetative state.

A patient in a permanent vegetative state required general anaesthesia for dental surgery. Because of the uncertainties involved in the appropriate monitoring and assessment of the conscious level of patients in a permanent vegetative state, it was decided to use the bispectral index to help guide the anaesthetic depth during surgery. We found that the bispectral index profile during anaesthesia and surgery was similar to that of a normal subject. The findings raise the possibility that patients in permanent vegetative states might sense noxious stimuli at a cortical level
