Pain in the forearm is relatively common in the community. In the workplace forearm pain is associated with work involving frequent repetition, high forces, and prolonged abnormal postures. Nevertheless, other factors are involved in the presentation and the continuation of the pain. Notable among these factors are psychosocial issues and the workplace environment-the attitude to workers and their welfare, the physical conditions, and design of the job. Primary prevention may be effective but active surveillance is important with early intervention and an active management approach. Physical treatments have not been extensively evaluated. In the established case, management should be multidisciplinary, addressing physical aspects of the job but also addressing the "yellow, blue, and black flags" which should be viewed as obstacles to recovery. For the worker "on sick" a dialogue should be established between the worker, the primary care physician, and the workplace. Return to work should be encouraged and facilitated by medical interventions and light duty options. Rehabilitation programmes may be of use in chronic cases. 相似文献

The semimechanized and repetitive nature of industry, the greater use of keyboards, and the need to boost production during an economic recession have led to a huge increase in repetitive strain injuries. The types of injury, their diagnosis and their treatment are discussed. 相似文献

Repetition strain injury: a review of current understanding 总被引:3,自引:0,他引:3

"Repetition strain injury" (RSI) is a controversial condition and has become a major occupational health problem in Australia. It seems to be a disorder that is consequent to the introduction of new technology without due concern for human performance. The introduction of mechanized and partly automated processes apparently has made physical workloads lighter but has resulted in an increased regularity of physical movement with workloads that frequently are concentrated locally. Mechanization and automation have also produced an increased rate of work. A combination of several factors, each of which in itself is seemingly tolerable, may lead to this occupational hazard. Physical, psychological and ergonomic aspects may contribute to the condition but there are no useful diagnostic investigations. The pathology is unknown. Management of the condition requires carefully supervised treatment of the patient and his or her environment. The prevention of RSI necessitates improved organizational and ergonomic control in the work environment. Fundamental research into its causes, natural history and pathophysiology is essential for the development of scientifically based preventive strategies and patient therapy. 相似文献

An epidemic of "repetition strain injury" ("RSI") in Telecom Australia is described. In the years 1981-1985, there have been 3976 reports of "RSI". The occupation that was most affected was that of telephonist, with 1886 reports and a rate of 343 per 1000 keyboard staff members over five years; among other occupations that were affected were clerical workers (1421 reports; rate, 284 per 1000 keyboard staff members); telegraphists (17 reports; rate, 34 per 1000 staff members); and process workers (235 reports; rate, 116 per 1000 staff members). Women accounted for 3330 (83%) of all reports; in the telephonist group, 27% of female and 20% of male staff members were affected (P less than 0.001); for women, younger staff members were more affected. There was a significant difference among states in the prevalence of "RSI" in telephonists. There was a high morbidity, and 644 (16%) subjects were affected for more than 26 weeks; the cost-effectiveness of treatment and rehabilitation varied appreciably among state administrations. The costs of the epidemic exceed $15 million, including $1.8 million in medical costs. Reasons for the rise and decline of the epidemic are discussed. 相似文献

目的 研究不同平台压参数设置下,急性肺损伤(acute lung injury, ALI)家猪的跨肺压(transpulmonary pressure)等呼吸力学参数,明确平台压30cmH2O能否全面准确反应ARDS呼吸力学情况。方法 将6只健康家猪麻醉、进行外科手术后,按照以下不同实验状态进行机械通气: A组平台压<30cmH2O、B组平台压>30cmH2O伴腹内高压(intra-abdominal hypertension, IAH)。观察不同分组通气参数设置下,肺应力、平台压等呼吸力学标。结果呼吸力学: A组肺应力为(15.07±1.47)cmH2O高于 B组(10.92±1.28)cmH2O;B组胸壁弹性阻力与呼吸系统弹性阻力之比(Ecw/Ers)为(0.36±0.06)高于A组(0.24±0.05);B组肺顺应性(Cdyn)为(13.38±2.79)ml/cmH2O,明显高于A组(10.26±1.18)ml/cmH2O ;差异均有统计学意义(P<0.01)。B组胸壁顺应性(Ccw)为(43.12±8.00)ml/cmH2O,低于A组(63.28±36.71)ml/cmH2O,差异均有统计学意义(P<0.01)。结论 单纯以平台压30cmH2O作为机械通气的标准,不能准确地反映ARDS患者肺部的呼吸力学。腹内高压时,需要更高的平台压来改善氧合状况。肺应力和应变是真正反应ARDS肺呼吸力学的指标,将肺应力和应变理论引入临床,有利于为ARDS患者制定更加安全、合理的通气策略。 相似文献

Pseudoseizures should be considered in the differential diagnosis of intractable seizures. Incorrect diagnosis may result in incorrect management, with the patient unnecessarily exposed to side effects of drugs. The authors report on three patients who presented with uncontrolled seizures originally diagnosed and managed as status epilepticus. Electroencephalography performed during provoked attacks led to a diagnosis of pseudoseizures. Psychiatric assessment revealed psychologic disorders. The patients received supportive therapy, and the pseudoseizures stopped. 相似文献

目的研究重复神经刺激技术(RNS)对重症肌无力(MG)疾病的诊断价值。方法分别对我院诊治的36例MG患的面神经、腋神经及尺神经进行RNS检查,共检查108条神经。结果108条神经中RNS阳性率为60.2%(65条),其中以腋神经对应的三角肌阳性率最高,为77.8%(28/36),尺神经对应的小指展肌阳性率最低,为41.7%(15/36)。同一患有一条或多条神经RNS阳性的病例数为总例数的86.1%(31/36)。所有RNS阳性的MG患在低频刺激即可获得阳性结果,最佳刺激频率为3~5Hz。结论对MG患同时进行腋神经、面神经和尺神经的重频刺激,可提高RNS的阳性率。 相似文献
