Enhancing rehabilitation of motor deficits with peripheral nerve stimulation

A number of different neurorehabilitation strategies include manipulation of the somatosensory system, e.g. in the form of training by passive movement. Recently, peripheral electrical nerve stimulation has been proposed as a simple, painless method of enhancing rehabilitation of motor deficits. Several physiological studies both in animals and in humans indicate that a prolonged period of patterned peripheral electrical stimulation induces short-term plasticity at multiple levels of the motor system. Small-scale studies in humans indicate that these plastic changes are linked with improvement in motor function, particularly in patients with chronic motor deficits after stroke. Somatosensory-mediated disinhibition of motor pathways is a possible underlying mechanism and might explain why peripheral electrical stimulation is more effective when combined with active training. Further large-scale studies are needed to identify the optimal stimulation protocol and the patient groups that stand to benefit the most from this technique.

Gender differences in cardiac rehabilitation outcomes: do women benefit equally in psychological health?

BACKGROUND: Psychological factors are important in the etiology and prognosis of coronary heart disease (CHD). Cardiac rehabilitation (CR) aims to reduce psychological distress, besides other somatic risk factors. Studies have shown that CR is effective in reducing psychological distress, but little is known about gender-specific outcome differences. Our objective was to examine whether women and men benefit equally from outpatient CR in terms of reduction in psychological distress and whether women show more impaired psychological health at baseline of CR than do men. METHODS: We enrolled 441 CHD patients (mean age 58+/-11 years, 79.8% men) who underwent a 12-week outpatient CR program. Psychological dimensions, namely, anxiety, depression, vital exhaustion, social inhibition, and negative affect, were assessed at baseline and post-CR. Multivariate analysis of variance (MANOVA), controlling for age, disease severity, and exercise capacity, was applied to test for gender-specific differences at baseline and change between baseline and post-CR. In addition, gender-specific effect sizes were calculated for the change on psychological dimensions. RESULTS: Women and men did not differ on any psychological measure at baseline of CR. The effect sizes show small to moderate treatment effects on the psychological dimensions assessed. Gender had a significant impact on change on the dimensions vital exhaustion (F=5.040(df=1), p<0.05) and social inhibition (F=5.74(df=1), p<0.05). Women showed larger change on social inhibition and smaller change on vital exhaustion than men. CONCLUSIONS: Women and men do not differ in the extent of psychological distress at baseline of CR, which could be explained also by the exclusion of highly distressed women from treatment. CR is less effective among women with regard to vital exhaustion and more effective with regard to social inhibition compared with men in a sample of low distressed patients.

[Implementation of a routine gradual psycho-diagnostic programme in somatic rehabilitation centres - results of a pilot study]

STUDY AIM: A pilot study was conducted to implement and evaluate a routine gradual psycho-diagnostic programme to improve diagnostics and treatment of mental disorders in somatic rehabilitation centres. First of all, implementation strategies were acquired in trainings together with psychologists and physicians. The psycho-diagnostic programme consists of a screening instrument (PHQ-9) designed to permit time-effective detection of comorbid mental disorders. Besides evaluation of the training, the aim of the study was to analyze the extent to which it is possible to implement the routine gradual psycho-diagnostic programme in practice. Additionally, it was intended to identify beneficial and obstructive conditions for implementation. METHODOLOGY: The pilot study was conducted in two orthopaedic and one cardiological rehabilitation centre. The training was evaluated directly after its completion using a questionnaire. Three months after its implementation, the introduction of the psycho-diagnostic programme was evaluated using interviews with n=11 physicians and psychologists. RESULTS: The training was rated positively by the participants . Implementation of the entire gradual psycho-diagnostic programme was possible in one centre and to some degree in the other two. Beneficial for implementation were a frank organisational climate, sufficient time resources, and physicians' biopsychosocial understanding of disease. A dismissive attitude towards psycho-diagnostics, little communication between staff members, little perceived advantage for one's own work and fear to stigmatise patients by psychiatric diagnoses were obstructive. CONCLUSION: Essential for a successful implementation are sufficient time and personal resources, a motivation for change in staff and centre management, and a positive attitude regarding psycho-diagnostics in clinic staff. Furthermore, flexibility in implementation strategies and the opportunity to participate in the implementation process are important.

Fixed mandibular and maxillary implant rehabilitation in a fully edentulous patient: a case report

The complete dental rehabilitation of a patient with a failing dentition using fixed implant-supported prostheses requires carefully planned and well-sequenced treatment. This case report presents the treatment steps and sequencing for a patient in whom removable provisional prostheses were not an option. While an immediate loading protocol was used in the mandible, a staged approach featuring strategic extractions and implant placement in several phases was applied in the maxilla. The major advantage of this treatment protocol was that the patient was maintained in fixed prostheses throughout the treatment.

[Rehabilitation of a periodontally compromised dentition with implant-supported zirconia bridges. Case report]

Clinical aspects of reconstruction with fix prosthesis and dental implants in a patient with a history of periodontitis is shown. A successful stabilization and rehabilitation of the periodontally involved dentition can be achieved with tooth-worn crown and bridge reconstructions. From a functional and aesthetic point of view the result may not be satisfying due to mobility and overlength of the teeth and open approximal spaces. Today, dentist and patient have often to weigh if teeth shall be maintained or replaced by dental implants. Thereby, both must be aware of the fact that in complex cases long-term success and aesthetic outcome may be difficult to predict. An intense discussion with the patient on his expectations, invasive treatment, risks with regard to biologic and prosthetic aspects is mandatory and must be based on the best scientific evidence available. The present case report shows different considerations and describes a radical solution which meets the patient's needs and is based on modern CAD-CAM technology.

Three-year cost analysis of function-centred versus pain-centred inpatient rehabilitation in patients with chronic non-specific low back pain

OBJECTIVE: To compare costs of function- and pain-centred inpatient treatment in patients with chronic low back pain over 3 years of follow-up. DESIGN: Cost analysis of a randomized controlled trial. PATIENTS: A total of 174 patients with chronic low back pain were randomized to function- or pain-centred inpatient treatment. METHODS: Data on direct and indirect costs were gathered by questionnaires sent to patients, health insurance providers, employers, and the Swiss Disability Insurance Company. RESULTS: There was a non-significant difference in total medical costs after 3 years' follow-up. Total costs were 77,305 Euros in the function-centred inpatient treatment group and 83,085 Euros in the pain-centred inpatient treatment group. Likewise, indirect costs after 3 years from lost work days were non-significantly lower in the function-centred in-patient treatment group (6354 Euros; 95% confidence interval -20,892, 8392) and direct medical costs were non-significantly higher in the function-centred inpatient treatment group (574 Euros; 95% confidence interval -862, 2011). CONCLUSION: The total costs of function-centred and pain-centred inpatient treatment were similar over the whole 3-year follow-up.
