“Stops walking when talking” as a predictor of falls in elderly people

It was our clinical experience that some frail elderly patients stop walking when they start a conversation with a walking companion, presumably because walking demands attention and they stop when they are expected to do two things at once. We therefore investigated the usefulness of the sign “stops walking when talking” in predicting falls. 58 residents in sheltered accommodation in Umea, Sweden, were included. All were able to walk with or without aids and able to follow simple instructions (mean age [SD] 80·1 [6·1] years; 72% women). The most common diagnoses (some had more than one) were dementia (n=26), depression (25), and previous stroke (20). The median score (inter-quartile range) of the Mini-Mental State Examination 1 was 21·5 (18‐26) and the score of activities of daily living was 17 (14‐19) as measured by the Barthel Index. 2 Participants were observed by a physiotherapist while they were accompanied from their home to an assessment room, and whether or not they stopped walking when a conversation started was recorded. Furthermore, their ability to walk safely was rated and basic functional mobility was measured. 3 The staff registered falls indoors during a followup of 6 months. Neither participants nor staff were aware of the physiotherapist’s observations. 12 people stopped walking when a conversation started and ten of them fell during the 6-month follow-up. 21 people fell at least once. Kaplan-Meier distributions of falls differed significantly between those who stopped walking and those who continued to walk (figure, log-rank test 17·46, p0·001). The positive predictive value of “stops walking when talking” was 83% (10/12) and the negative predictive value was 76% (35/46). The specificity was high (95%; 35/37) but the sensitivity was low (48%; 10/21). Those who stopped walking had a significantly less safe gait (p<0·001), Myocardial contrast

Acute Confusional States in Elderly Patients Treated for Femoral Neck Fracture

The aims of this study were to estimate the incidence of acute confusional state (ACS), its predisposing factors and consequences in 111 consecutive patients operated for fractured neck of the femur. The incidence of ACS was 61 percent and the predicting factors were old age and dementia. Drugs with anticholinergic effect, depression, and previous stroke were factors that seemed to be associated with the development of ACS. Ninety‐two percent of the patients who had severe perioperative blood pressure drops developed ACS. The consequences of ACS were prolonged ward‐stay at the orthopedic department, a greater need for long‐term care after discharge, and poor walking ability at discharge and six months after surgery. The confused patients also had more complications, such as urinary problems, feeding problems and decubital ulcers, as compared with the nonconfused patients.

Resilience, sense of coherence, purpose in life and self-transcendence in relation to perceived physical and mental health among the oldest old.

Different concepts have been presented which denote driving forces and strengths that contribute to a persons ability to meet and handle adversities, and keep or regain health. The aim of this study, which is a part of The Umeå 85+ study, was to describe resilience, sense of coherence, purpose in life and self-transcendence in relation to perceived physical and mental health in a sample of the oldest old. The study sample consisted of 125 participants 85 years of age or older, who ranked themselves on the Resilience Scale, Sense of Coherence Scale, Purpose in Life Scale and Self-Transcendence Scale and answered the SF-36 Health Survey questionnaire. The findings showed significant correlations between scores on the Resilience Scale, the Sense of Coherence Scale, the Purpose in Life Test, and the Self-Transcendence Scale. Significant correlations were also found between these scales and the SF-36 Mental Health Summary among women but not among men. There was no significant correlation between perceived physical and mental health. The mean values of the different scales showed that the oldest old have the same or higher scores than younger age groups. Regression analyses also revealed sex differences regarding mental health. The conclusions are that, the correlation between scores on the different scales suggests that the scales measure some dimension of inner strength and that the oldest old have this strength at least in the same extent as younger adults. Another conclusion is that the dimensions that constitute mental health differ between women and men.

Patient Falls in Stroke Rehabilitation A Challenge to Rehabilitation Strategies

BACKGROUND AND PURPOSE The risk of falls is very high among stroke patients, and falling is a major complication in stroke rehabilitation. This study aimed to investigate the incidence, characteristics, and consequences of falls in an inpatient stroke rehabilitation setting. METHODS One hundred sixty-one patients consecutively admitted to a geriatric stroke rehabilitation unit were studied. Falls that occurred during their rehabilitation stay were prospectively registered and analyzed. RESULTS Sixty-two of the patients (39%) suffered falls. The total number of falls was 153, which corresponds to an incidence rate of 159 falls per 10,000 patient-days. Most falls occurred during transfers or from sitting in a wheelchair or on some other kind of furniture. Seventeen falls (11%) were classified as the result of extrinsic mechanisms, 49 (32%) were intrinsic falls, 39 (25%) occurred in a nonbipedal position (while sitting or lying), and 48 falls (31%) remained unclassified. No injury was observed in 109 of 153 incidents (71%), whereas 6 falls (4%) involved fractures or other serious injury. CONCLUSIONS Since falls are so frequent, they must be considered a significant problem in stroke rehabilitation. Fall prevention strategies should therefore be developed and included in rehabilitation programs.

Fractures After Stroke

Abstract. Fractures are a serious complication after stroke. Among patients with femoral neck fractures, a large subgroup have had a previous stroke. This study aimed to investigate the incidence of fractures after stroke. Included in the study were 1139 patients consecutively admitted for acute stroke. Fractures occurring from stroke onset until the end of the study or death were registered retrospectively. Hip fracture incidence was compared with corresponding rates from the general population. Patients were followed up for a total of 4132 patient-years (median 2.9 years). There were 154 fractures in 120 patients and median time between the onset of stroke and the first fracture was 24 months. Women had significantly more fractures than men (χ2 = 15.6; p < 0.001). In patients with paresis most of the fractures affected the paretic side (χ2 = 22.5; p < 0.001) and 84% of the fractures were cause by falls. Hip fracture was the most frequent fracture and the incidence was 2–4 times higher in stroke patients compared with the reference population. Fractures are thus a common complication after stroke. They are usually caused by falls and affect the paretic side. It is necessary to focus on the prevention of post-stroke fractures, including the prevention of both falls and osteoporosis.

Attention, frailty, and falls : the effect of a manual task on basic mobility

OBJECTIVE: To investigate the effect of a second task on balance and gait maneuvers used in everyday life. Our hypothesis was that those who were more distracted by a familiar manual task performed concurrently with functional maneuvers were more frail and more prone to falls.

A Geriatric-Anesthesiologic Program To Reduce Acute Confusional States in Elderly Patients Treated for Femoral Neck Fractures

The aim of this study was to evaluate the effect of a geriatrk‐anesthesiologic intervention program for the prevention and treatment of acute confusional states (ACS) in elderly patients treated for femoral neck fractures. The intervention program was based on the results of previous prospective studies in similar patient populations. The outcome of the intervention, comprising 103 patients, was compared with that of an earlier study comprising 111 patients. The intervention program consisted of pre‐ and post‐operative geriatric assessments, oxygen therapy, early surgery, prevention and treatment of peri‐operative blood pressure falls and treatment of post‐operative complications. The incidence of ACS was lower, 47.6%, in the intervention study compared with 61.3% (P < 0.05) in the control study. Furthermore, the ACS that occurred in the intervention study was less severe and of shorter duration than that in the control study. The incidence of post‐operative decubital ulcers, severe falls, and urinary retention was also lower. The mean duration of orthopedic ward stay was 17.4 days in the control study and 11.6 days in the intervention study (P < 0.001). It can be concluded that the intervention program reduced the incidence, severity, and duration of ACS which resulted in a shortened orthopedic ward stay.

Obstructive Sleep Apnea Is a Risk Factor for Death in Patients With Stroke: A 10-Year Follow-up

BACKGROUND Sleep apnea occurs frequently among patients with stroke, but it is still unknown whether a diagnosis of sleep apnea is an independent risk factor for mortality. We aimed to investigate whether obstructive or central sleep apnea was related to reduced long-term survival among patients with stroke. METHODS Of 151 patients admitted for in-hospital stroke rehabilitation in the catchment area of Umeå from April 1, 1995, to May 1, 1997, 132 underwent overnight sleep apnea recordings at a mean (SD) of 23 (8) days after the onset of stroke. All patients were followed up prospectively for a mean (SD) of 10.0 (0.6) years, with death as the primary outcome; no one was lost to follow-up. Obstructive sleep apnea was defined when the obstructive apnea-hypopnea index was 15 or greater, and central sleep apnea was defined when the central apnea-hypopnea index was 15 or greater. Patients with obstructive and central apnea-hypopnea indexes of less than 15 served as control subjects. RESULTS Of 132 enrolled patients, 116 had died at follow-up. The risk of death was higher among the 23 patients with obstructive sleep apnea than controls (adjusted hazard ratio, 1.76; 95% confidence interval, 1.05-2.95; P = .03), independent of age, sex, body mass index, smoking, hypertension, diabetes mellitus, atrial fibrillation, Mini-Mental State Examination score, and Barthel index of activities of daily living. There was no difference in mortality between the 28 patients with central sleep apnea and controls (adjusted hazard ratio, 1.07; 95% confidence interval, 0.65-1.76; P = .80). CONCLUSIONS Patients with stroke and obstructive sleep apnea have an increased risk of early death. Central sleep apnea was not related to early death among the present patients.

Stroke, a Major and Increasing Risk Factor for Femoral Neck Fracture

BACKGROUND AND PURPOSE Patients with stroke have up to a 4-fold increased risk of hip fracture because of their high incidence of falls and loss of bone mass in the paretic side, ie, hemiosteoporosis. The purpose of this study was to investigate the prevalence of previous stroke among patients with femoral neck fracture. METHODS The study included all 568 patients, aged >/=65 years, who underwent surgery for femoral neck fracture in 1980, 1983, 1987, 1993, and 1997 at the orthopedic clinic of Umeå University Hospital, Umeå, Sweden. RESULTS The prevalence of previous strokes ranged from 16.4% to 38.5% (P<0.001); this finding is only partly explained by the increased incidence of stroke in the corresponding population, and there was no significant increase in the overall incidence of femoral neck fracture. Fractures occurred 5.4+/-6.4 years after stroke (median 2.9 years, range 0 to 33 years). In stroke patients with unilateral stroke and persisting paresis at the time of fracture, 62.5% had their fracture on the paretic side (P=0. 034). Survival was significantly reduced in patients with previous stroke (P<0.001). In patients previously independently mobile, 69.2% with no previous stroke and 38.1% with previous stroke were still mobile at discharge from the orthopedic unit (P<0.001). CONCLUSIONS Attention must be focused on stroke as a major and increasing risk factor for femoral neck fracture and also on the poor postfracture outcome and reduced survival of these patients. Prevention of poststroke fractures is necessary and is aimed at reducing the risk of poststroke fall and preventing the development of hemiosteoporosis.
