Randomized Controlled Trial Multicenter Study Clinical Trial
Pain and quality of life in patients with critical limb ischaemia: results of a randomized controlled multicentre study on the effect of spinal cord stimulation. ESES study group.
We carried out an assessment of pain and quality of life of patients with critical limb ischaemia during the follow-up of a multicentre randomized trial in more detail than previously reported. In a multicentre clinical trial 120 patients were randomized between medical treatment and medical treatment plus spinal cord stimulation. Patients were selected on the basis of clinical symptoms and macrocirculatory data as described in the European consensus document on critical limb ischaemia. ⋯ Amputation had a negative effect on mobility, resulting in a difficult rehabilitation but relieved pain substantially (p<0. 05). In contrast to the existing literature, the randomized trial revealed no major difference in overall pain and quality of life assessment between treatment groups. The effect on energy and mobility was significantly better in patients treated with SCS, who also used substantially fewer analgesics.

Stroke is a common disease often requiring rehabilitation, which may be prolonged by shoulder pain. The true incidence of post stroke shoulder pain has not been fully evaluated. In order to establish this, we undertook a prospective study of 123 consecutive patients with a diagnosis of acute stroke during a 6-month period. ⋯ We conclude that post stroke shoulder pain is more common than previously realized and in addition to abnormal shoulder joint examination may also be associated with upper limb sensory impairment. Thorough neurological examination is required to detect sensory loss and hence establish patients at risk. This is probably best done by a structured proforma.

Randomized Controlled Trial Clinical Trial
The analgesic efficacy of topical capsaicin is enhanced by glyceryl trinitrate in painful osteoarthritis: a randomized, double blind, placebo controlled study.
The aim of this study was to assess if the pain of osteoarthritis is reduced by topical capsaicin and to determine whether addition of glyceryl trinitrate has an effect on analgesic efficacy and tolerability of capsaicin. A randomized, double blind, placebo controlled study was carried out on 200 adult patients attending a Pain Clinic with osteoarthritis pain. Patients applied one of four creams topically over the affected joint over a 6 week period. ⋯ The study showed that topical capsaicin and glyceryl trinitrate have an analgesic effect in painful osteoarthritis. When used together this effect is increased with the combination being more tolerable than capsaicin alone. Analgesic consumption is decreased by capsaicin, glyceryl trinitrate and to a greater extent by both combined.

Randomized Controlled Trial Comparative Study Clinical Trial
Plasma levels after peroral and topical ibuprofen and effects upon low pH-induced cutaneous and muscle pain.
Cutaneous applications are gaining popularity in the treatment of cutaneous pain and of painful disorders in joints and muscle. The low pH-pain model in human skin has previously been able to demonstrate the effects of NSAIDs in dose-dependent manner and to establish time-effect relationships. We examined the analgesic action of ibuprofen after cutaneous application and compared the effects with oral administration. ⋯ In the muscle model, the commercial ibuprofen gel did not reduce the pain in the acidic muscle. The peroral ibuprofen was less effective in the muscle compared to the skin pain model, although there was a significant progressive pain reduction within 55 min. Reasons for the differential susceptibility of cutaneous vs muscular acidosis pain to ibuprofen remain to be established.

Clinical studies have demonstrated that osteoarthritic pain is strongly linked to disability and quality of life. Pain relief enables patients to regain their mobility and is therefore a key goal in the management of osteoarthritis (OA). Osteoarthritis pain is of multifactorial origin, and inflammatory mechanisms play only a partial role. ⋯ However, the choice of analgesic treatment in OA must be highly individual. No guidelines can rigidly define a treatment regimen for such a condition as OA. Simple hints are given how to best use tramadol by selecting the right patients and choosing the right dosing strategy.
