A study of 589 consecutive implants supporting complete fixed prostheses. Part I: Periodontal aspects.

Ninety-one consecutive edentulous patients who had been treated by means of fixed prostheses (n = 103) supported by Br?nemark implants (n = 589) were examined. Eighteen fixtures (3%) failed to integrate. After a mean loading time of 32 (range 6 to 80) and 38 months (range 5 to 83) for fixtures in the maxilla and mandible, respectively, an additional 12 fixtures lost integration. The cumulative failure rate for individual fixtures after 6 years was 8.4% and 5% for maxillae and mandibles, respectively. Only one patient had to revert to complete dentures. For fixtures in the maxillae, the mean marginal bone loss was 0.7, 0.1, and 0.2 mm for each of the first 3 years of loading, respectively; for fixtures in mandibles, the corresponding values were 0.7, 0.2, and 0.1 mm. The loss in marginal bone height was equal in both jaws and was not related to bleeding on probing or to the preoperative resorption anatomy.     

Poststroke fatigue: course and its relation to personal and stroke-related factors

OBJECTIVES: To describe the course of fatigue during the first year poststroke and to determine the relation between fatigue at 1 year poststroke and personal characteristics, stroke characteristics, and poststroke impairments. DESIGN: Inception cohort. SETTING: Rehabilitation center. PARTICIPANTS: Patients (N=167) with a first-ever supratentorial stroke admitted for inpatient rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: The Fatigue Severity Scale measured the presence and impact of fatigue at admittance for inpatient rehabilitation, as well as at 6 months and 1 year poststroke. RESULTS: At admission, 6 months and 1 year poststroke, fatigue was present in 51.5%, 64.1%, and 69.5% of the patients, respectively. Fatigue impact 1 year poststroke was greater among patients with more depressive symptoms, higher age, women, and patients with a locus of control more directed to powerful others. CONCLUSIONS: Because fatigue impact is an increasing problem during the first year poststroke, it deserves more attention in clinical practice and scientific research. Locus of control and depression are related to poststroke fatigue and might be important foci for future interventions.     

Effects of exercise training programs on walking competency after stroke: a systematic review

To determine the effectiveness of training programs that focus on lower-limb strengthening, cardiorespiratory fitness, or gait-oriented tasks in improving gait, gait-related activities, and health-related quality of life after stroke. Randomized controlled trials (RCTs) were searched for in the databases of Pubmed, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, DARE, Physiotherapy Evidence Database (PEDro), EMBASE, Database of the Dutch Institute of Allied Health Care, and CINAHL. Databases were systematically searched by two independent researchers. The following inclusion criteria were applied: (1) participants were people with stroke, older than 18 yrs; (2) one of the outcomes focused on gait-related activities; (3) the studies evaluated the effectiveness of therapy programs focusing on lower-limb strengthening, cardiorespiratory fitness, or gait-oriented training; and (4) the study was published in English, German, or Dutch. Studies were collected up to November 2005, and their methodological quality was assessed using the PEDro scale. Studies were pooled and summarized effect sizes were calculated. Best-evidence synthesis was applied if pooling was impossible. Twenty-one RCTs were included, of which five focused on lower-limb strengthening, two on cardiorespiratory fitness training (e.g., cycling exercises), and 14 on gait-oriented training. Median PEDro score was 7. Meta-analysis showed a significant medium effect of gait-oriented training interventions on both gait speed and walking distance, whereas a small, nonsignificant effect size was found on balance. Cardiorespiratory fitness programs had a nonsignificant medium effect size on gait speed. No significant effects were found for programs targeting lower-limb strengthening. In the best-evidence synthesis, strong evidence was found to support cardiorespiratory training for stair-climbing performance. Although functional mobility was positively affected, no evidence was found that activities of daily living, instrumental activities of daily living, or health-related quality of life were significantly affected by gait-oriented training. This review shows that gait-oriented training is effective in improving walking competency after stroke.     

Rehabilitation of stroke patients needs a family-centred approach

Purpose. To highlight the importance of the spouse in stroke rehabilitation. Stroke not only affects the patients, but also their families, but rehabilitation practice is still primarily focused on the patient only.

Method. Analysis of the position of the spouse and possible consequences of stroke for the spouse, based on the literature.

Results. Three roles of spouses are described: (i) the role of caregiver, as the spouse often provides extensive and comprehensive care for the patient; (ii) the role of client, as this informal care may lead to physical and emotional strain; and (iii) the role of family member, as the stroke affects the interpersonal relationships within the family system, not least the emotional and sexual relationship between the partners. This analysis provides an understanding of problems experienced by spouses as roles conflict and identifies topics for assessment and interventions directed at the spouse in the acute phase, rehabilitation phase and chronic phase of stroke.

Conclusion. We support a family-centred approach in which the strengths and needs of all family members, the patient with stroke included, are considered throughout all phases of the rehabilitation process.     

Prediction of social activity 1 year poststroke

OBJECTIVE: To develop an easy-to-use prediction rule for social activity 1 year poststroke that can identify patients at risk for social inactivity. DESIGN: Inception cohort. SETTING: Rehabilitation center. PARTICIPANTS: Patients with a first-ever supratentorial stroke were selected in 4 Dutch rehabilitation centers. Data of 250 patients were available for analysis. Potential prognostic factors measured at admission were sex, age, marital status, prestroke employment status, educational level, type of stroke, hemisphere, motor impairment, trunk control, communication, and activities of daily living (ADL) dependency. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Social activity measured by the Frenchay Activities Index (FAI) at 1 year poststroke. RESULTS: Multivariate backward linear regression analysis identified sex, age, marital status, motor impairment, communication, and ADL dependency as important predictors of the FAI score 1 year poststroke. An easy-to-use score chart was constructed that could identify patients at risk for social inactivity. The score chart proved to be well able to discriminate poor social functioning from moderate to good social functioning (area under the curve = .85). CONCLUSIONS: Identifying patients at risk enables health care professionals to focus on the social activity of this patient subgroup at an early stage in the care process.
