The intradiscal lumbar pressure was measured in 10 patients with para- or tetraplegia and in one normal subject. The pressure was registered both in the horizontal position and during tilting on a table, during the performance of a standardized exercise program for the upper extremities, as well as during cough, during abdominal strain and while the subjects were being turned from the supine to the lateral position. The increase in pressure during the tilting to an angle of +30 degrees, and mostly to +50 degrees was less than the maximum pressure change during the exercises to which an immobilized patient with acute unstable fracture of the spine, was exposed daily, such as being turned, performing respiratory exercises and muscular training for the upper extremities. Provided fixation was secured with a belt, patients with unstable fractures of the thoracic and lumbar spine maybe treated with a "more active immobilization" tilting them in the bed even during the acute stage. Forward flexion exercises in the shoulder joints with hand weights produced a greater increase of the intradiscal pressure than did abduction exercises with the corresponding load. Spasticity produced a considerable increase in intradiscal pressure.

To study sudden unexplained death syndrome (SUDS) in north-east Thailand, a mailed screening questionnaire and direct retrospective interview of relatives or witnesses of the incident was carried out in four administrative districts of Khon Kaen Province, north-east Thailand. Healthy villagers, 20-49 years, who died suddenly without explanation were identified as cases. Live healthy villagers who were age- and sex-matched with the dead served as controls. The study showed that all but one case were male with a mean age of 38 +/- 8 years. The incidence of SUDS was 38 per 100,000 men 20-49 years old per year. The peak risk was at 45-49 years. About 75% of SUDS cases had an annual income per household of less than the mean per capita income in Thailand. There were more SUDS cases in the hot season than any other season. The onset was nocturnal in 84% of cases. Presence of SUDS in family members was more frequently found in cases than in controls (P < 0.001). A history of muscle soreness, malaise and recent hard labour were seen as frequently in SUDS victims as in controls. In witnessed cases, symptoms usually lasted for a few minutes prior to death. Common symptoms or signs were respiratory (groaning, choking or coughing) and muscular spasticity or paralysis. The most consistent but yet unexplained finding in this study is the association between the onset of SUDS and the rest period.

The results of numerous studies of occupational bronchial asthma proved that bronchial spasticity and nonspecific bronchial hyperreactivity persists after cessation of occupational exposure. The aim of the study was to evaluate the condition of patients with bronchial asthma after cessation of occupational exposure. A group of 23 patients with bronchial asthma had been observed twice: 1-6 months after cessation of occupational exposure and then 36 or 48 months later. An analysis of the clinical progress, both during the diagnostic process and the control examination, was based on a questionnaire including questions on cough intensity, dysponca, mean daily use of aerosol beta-mimetics and daily oral and inhalatory doses of corticosteroids. The analysis covered the month during the year proceeding the examination in which patients found themselves in the best psychosomatic condition. During both periods considered by patients themselves as the best ones from the clinical point of view, respiratory function tests and allergological tests were performed. The majority of patients with occupational bronchial asthma had reported, 2-3 years after cessation of occupational exposure, subjective complaints which indicated the improvement of their clinical condition. In those patients, the decrease in the intensity of specific allergic reactions was not observed. In the majority of patients with occupational bronchial asthma nonspecific bronchial hyperreactivity has not diminished despite a two-year break in occupational exposure.

Patients with developmental disorders, including adolescents, comprise a large and heterogeneous group of individuals who vary in underlying diagnosis and degree of disability. The largest numbers of patients are those with cerebral palsy and with traumatic brain injury. While these conditions themselves do not directly cause airway or parenchymal lung dysfunction, consequences of neuromuscular dysfunction, especially aspiration and ineffective cough, may lead to lung damage. Poor nutritional status, impairment of airway clearance by muscular weakness or incoordination and poor pulmonary reserve (due to chest wall or spine deformity) increase the risk of significant morbidity and mortality from respiratory infections. Individuals who were premature infants or who had prolonged neonatal courses may also have residual chronic lung disease (bronchopulmonary dysplasia) contributing to their pulmonary problems. This review discusses conditions that have adverse effects on the airway and lung (drooling, feeding problems, gastroesophageal reflux, aspiration, spasticity, scoliosis) and some of the consequences of these insults (disordered airway clearance, pneumonia, sleep apnea). Also discussed are issues important to the prevention or amelioration of respiratory difficulties, including preventive care, the effects of exercise, dental hygiene, and surgical intervention.

Multiple Sclerosis (MS) is a disabling chronic neurological disorder with multiple motor impairments and its progressive course leads to severe disability. The question of the value of exercises program and physiotherapy to reduce these motor disorders and their consequences was raised. This literature overview is based on data from common database: Medline, Embase, Cochrane Library. Were selected articles corresponding to open studies and especially clinical controlled randomised trials. To be analysed, each article should correspond with inclusion criteria: confirmed diagnosis according to Poser's criteria, secondary or primary progressive form of MS without relapse for the study period, randomisation according to severity assessed by the Expanded Disability Status Scale (EDSS), no change in symptomatic drugs along the study period, and a simple blind assessor. Impairment, disabilities, handicap and quality of life had to be measured. Five clinical controlled randomised trials were consistent with these criteria. They demonstrated the effectiveness of comprehensive programs on motor function in the less severe forms of MS, but also their inability to change the course of the most severely affected forms. However, the effects on disability, handicap and quality of life were significant in comparison with control patients. These trials emphasised the value of multidisciplinary programs including physiotherapy and occupational therapy, carried out daily or 3 times a week by specialised staffs. The effects lasted only few weeks or months, requiring to propose them again after this period. Other controlled randomised studies also stressed the value of specific programs: temporary alleviation of spasticity and fatigue with cooling techniques; aerobic endurance training for less severely affected patients to prevent disuse consequences and improve fitness and quality of life; expiratory training to enhance coughing capacity and prevent pulmonary infections in very disabled patients. From this overview study, it seems that multidisciplinary comprehensive programs clearly provide benefits to those patients and contribute to reduce disability and improve quality of life at each stage of MS.

The use of electricity to stimulate nerves or muscles is nothing new. In the 18th century Galvani recognized that electricity could be converted into "nerve force". Numerous applications of electrical stimulation have been explored, most notably cardiac pacing, cochlear implants or transcutaneous electrical nerve stimulation (TENS) units for pain control. Spinal cord injury (SCI), with its "transecting lesion" that leaves intact nervous system below the injury completely disconnected from the centers that exert motor control provides the ideal opportunity for electrical stimulation use. Multiple applications are being investigated, including those for aerobic conditioning/cardiovascular exercise, cough and breathing assistance, improving bowel and bladder control, erection and ejaculation, hand grasp, spasticity management, neuro-muscular reeducation, standing and walking, etc. This review will focus on innovative and technologically advanced applications of electrical stimulation in the management of patients with spinal cord injury.

Patients with amyotrophic lateral sclerosis (ALS) have symptoms of progressive muscle weakness, of disturbed speech and swallowing, and in the terminal phase those of respiratory weakness. Treatment options, in particular those for excessive weight loss and respiratory weakness, should be introduced to the patients and their families when the patient is emotionally capable and before dysarthria severely hampers communication. Special equipment for keeping the patient as mobile as possible should be made available much earlier than in the case of other diseases of the muscles as in ALS progression is much faster. Cramps, pathological crying or laughter, spasms, and spasticity can all be treated by medication. When speech can no longer be understood, adaptive strategies such as sign language, mime, posture and communication apparatus varying from a note pad to advanced computer systems can be used. Sialorrhoea, caused by difficulty swallowing with its accompanying danger of aspiration can be halted by the use of medication, by radiotherapy and by the injection into the salivary glands of botulin A toxin. Weight loss, also a result of dysphagia, can be avoided by eating frequent small meals or if necessary performing a percutaneous endoscopic or radiological gastroscopy. Excess mucus in the respiratory tract can be treated with anticholinergics. Difficulty in coughing up thick and sticky mucus cannot always be adequately helped. Respiratory weakness is treatable by external respiratory supportive therapy using a nasal mask, as well as invasive respiratory support via a trachcostoma and by treating the symptoms of respiratory weakness. The latter form of treatment is palliative and forms part of terminal care. During the terminal phase restlessness, anxiety, pain, and dyspnoea require the most attention. Treatment requires careful multidisciplinary cooperation.

During the last one-half century, electrical stimulation has become clinically significant for improving health and restoring useful function after spinal cord injury. Short-term stimulation can be provided by electrodes on the skin or percutaneous fine wires, but implanted systems are preferable for long-term use. Electrical stimulation of intact lower motor neurons can exercise paralyzed muscles and reverse wasting; improve strength, endurance, and cardiovascular fitness; and may reduce the progression of osteoporosis. Other potential therapeutic uses being investigated include reduction of spasticity, prevention of deep vein thrombosis, and improvement of tissue health. Pacing of intact phrenic nerves in high tetraplegia can produce effective respiration without mechanical ventilation, allowing improved speech, increased mobility, and increased sense of well-being. Improvement of cough has also been demonstrated. Stimulation of intact sacral nerves can produce effective micturition and reduce urinary tract infection; it can also improve bowel function and erection. It is usually combined with posterior sacral rhizotomy to improve continence and bladder capacity, and the combination has been shown to reduce costs of care. Electroejaculation can now produce semen in most men with spinal cord injury. Significant achievements have also been made in restoring limb function. Useful hand grasp can be provided in C5 and C6 tetraplegia, reducing dependence on adapted equipment and assistants. Standing, assistance with transfers, and walking for short distances can be provided to selected persons with paraplegia, improving their access to objects, places, and opportunities that are inaccessible from a wheelchair. This review summarizes the current state of therapeutic and neuroprosthetic applications of electrical stimulation after spinal cord injury and identifies some future directions of research and clinical and commercial development.

The objective of this study was to identify prognostic factors for survival in amyotrophic lateral sclerosis from a large prospective observational study performed in France. The study included a cohort of 2069 patients fulfilling broad entry criteria treated with riluzole. Over 100 demographic, biological, clinical and quality-of-life variables were monitored and assessed for their effect on survival. Patients were randomized post hoc into two groups: one group (two-thirds of the patients) to generate the prognostic models and one group (one-third of the patients) to validate the resulting models. Thirteen variables were found to affect survival independently and were used to construct a survival prediction score, RL401. These included age, disease duration, slow vital capacity, intensity of tiredness (visual analogue scale), number of body levels with spasticity, atrophy and/or fasciculations, cough, distal muscle strength, household income, depression and two biological parameters, plasma creatinine levels and neutrophil counts. A simplified score, RL401S, was constructed, designed to be easy to use and interpret. The predictive powers of the two scores were similar.

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease. No treatment is currently able to stop the disease process. In the absence of new active compounds there is an urgent need to develop new strategies based on the neuroprotective activity of available drugs. ALS is a heterogeneous disease. To build up these therapeutic trials, we need to have a better understanding of the prognostic factors in this disease. During the Phase IV Rilutek Trial in France, we developed in a large population of patients a prognostic score based on clinical parameters available at the bedside. The most significant variables are vital capacity, spasticity, fasciculations, swallowing, cough and creatininemia. This score proved to be very useful in daily use in the clinic and for planning disease management in ALS as in the design of therapeutic trials. In ALS clinical trials, efficacy can be evaluated using survival or functional parameters. In phase II trials, function remains the most commonly used. In phase III trials, the gold standard endpoint remains the survival rate at month 18. We analyzed the most recent ALS trials published in the literature. This review suggests that in these trials there is a discrepancy between drug effects on survival versus function. These results suggest that a reappraisal of strategies to identify therapeutic targets for ALS is required.
