Assessment of quality of life in stroke patients with hemiplegia

Stroke is a major public health issue. Even though most hemiplegic stroke patients may obtain a good functional outcome, many remain dissatisfied with their lives. Indeed, quality of life and subjective well-being should be taken into account in any assessment of stroke survival.

OBJECTIVE

To assess long-term quality of life in stroke patients (compared with healthy controls) and the corresponding determinants and predictive factors.

METHOD

The patient population consisted of 80 of the 217 first-stroke survivors treated between January and June 2005 in the Clinical Neurosciences Department at Bordeaux University Hospital. After a mean follow-up period of 2 years, 24 patients were interviewed in their homes and data from the 56 others were obtained in a telephone interview. Demographic information, clinical status on admission and functional status (as assessed by Barthel Index) and depression (on the ADRS) at the time of the study visit were recorded. Quality of life was assessed by using the Sickness Impact Profile (SIP-65) and Bränholm and Fugl-Meyer's Satisfaction with Life Scale (LiSat 11). The patients' data were compared with those from 149 healthy controls.

RESULTS

Life satisfaction and quality of life were significantly impaired in stroke patients, compared with controls. All life domains were impaired. The worst scores were observed for independence and health-related items in the LiSat 11 and the physical and communication items in the SIP-65. Quality of life was strongly correlated with functional independence, the persistence of hemiplegia and depressive mood, which is in agreement with literature findings. Neither gender nor the initial Rankin score had a significant impact on these parameters.

DISCUSSION-CONCLUSION

Quality of life at 2 years is significantly impaired in stroke survivors and seems more difficult to predict than functional independence. However, in addition to these objective results, our interviews suggest that receiving adequate social support might be as important to patients as recovering independence.

A randomized controlled trial on early physiotherapy intervention versus usual care in acute care unit for elderly: potential benefits in light of dietary intakes

OBJECTIVE

To evaluate effects of early intensive physiotherapy during acute illness on post hospitalization activity daily living autonomy (ADL).

DESIGN

Prospective randomized controlled trial of intensive physiotherapy rehabilitation on day 1 to 2 after admission until clinical stability or usual care.

SETTING

acute care geriatric medicine ward.

PATIENTS

A total of 76 acutely ill patients, acutely bedridden or with reduced mobility but who were autonomous for mobility within the previous 3 months. Patients in palliative care or with limiting mobility pathology were excluded. Mean age was 85.4 (SD 6.6) years.

MEASUREMENTS

At admission, at clinical stability and one month later: anthropometry, energy and protein intakes, hand grip strength, ADL scores, and baseline inflammatory parameters. An exploratory principal axis analysis was performed on the baseline characteristics and general linear models were used to explore the course of ADL and nutritional variables.

RESULTS

A 4-factor solution was found explaining 71.7% of variance with a factor "nutrition", a factor "function" (18.8% of variance) for ADL, handgrip strength, bedridden state, energy and protein intakes, serum albumin and C-reactive protein concentrations; a factor "strength" and a fourth factor . During follow-up, dietary intakes, handgrip strength, and ADL scores improved but no changes occurred for anthropometric variables. Intervention was associated only with an increase in protein intake. Better improvement in ADL was found in intervention group when model was adjusted on "function" factor items.

CONCLUSION

Physical intervention programs should be proposed according to nutritional intakes with the aim of preventing illness induced disability.

Assessment of agonist-antagonist shoulder torque ratios in individuals with paraplegia: a new interpretative approach

STUDY DESIGN

Cross-sectional study.

OBJECTIVE

To evaluate isokinetic shoulder flexor-extensor (F/E) and abductor-adductor (Ab/Ad) torque ratios in individuals with paraplegia using a new interpretative approach. We proposed to study torque ratios according to joint angle sections (15 degrees angle subgroups) over a selected range of motion.

SETTING

Pathokinesiology Laboratory, Montreal, Canada.

METHOD

Sixteen individuals with complete motor paraplegia, without shoulder pain or impairment, were included in this study. After a preloading period of 1 s, maximum isokinetic concentric contractions of all muscle groups were completed at 30, 60 and 120 degrees s(-1) over the entire tested ranges of motion (70 to -35 degrees for the flexion-extension and 15 to 60 degrees for the abduction-adduction). After the continuous torque curves were rebuilt, the mean F/E and Ab/Ad torque ratios were calculated and analyzed every 15 degrees.

RESULTS

A significant modification of the F/E (F=66.3; P<0.001) and Ab/Ad (F=100.6; P<0.001) torque ratios was observed according to the 15 degrees angle subgroup evaluated. More precisely, a progressive decline of both the F/E and Ab/Ad ratios was noted as the shoulder flexion or abduction progressed. Angular velocity did not have any influence on torque ratio values.

CONCLUSION

Angle subgroup torque ratio analysis leads to a better estimation of the balance between the agonist and antagonist muscle groups than does traditional peak torque ratio analysis. In individuals with paraplegia, this precise estimation of torque ratios may lead to the development of specific shoulder strengthening programs to prevent muscle imbalance and its consequences.

Kinematic and electromyographic analysis of rising from a chair during a "Sit-to-Walk" task in elderly subjects: role of strength

BACKGROUND

With aging, the deterioration of the ability to rise from a chair constitutes a major source of disability and a factor contributing to the loss of autonomy. The aim of this study was to describe kinematic and electromyographic characteristics of rising from a chair during a Sit-to-Walk task and to investigate the relationships between lower limb muscle strength and Sit-to-Walk characteristics.

METHODS

Twenty-four healthy elderly subjects (mean age: 73.8 (6.4) years) were included. The task analyzed consisted in standing up and taking a step. Kinematic data were obtained using a 3D motion analysis software. Surface electromyography of eight lower limb muscles was recorded. Isokinetic strength of ankle plantar flexor and knee flexors and extensors was evaluated.

FINDINGS

The Sit-to-Walk was divided into four phases. For 19 subjects, this task can be considered as a continuum with an overlap of the phases. In comparison with the Sit-to-Stand description, the Sit-to-Walk transition phase, which combined trunk flexion and knee extension, appeared longer in order to increase the body forward transfer for gait initiation. In most cases, the tibialis anterior and peroneus longus muscles were first activated. The isokinetic strength of the knee extensors was negatively correlated with the amplitude of trunk flexion and the knee flexors/extensors torque ratio was correlated with the length of this phase.

INTERPRETATION

Characterization of Sit-to-Walk movement provides information about the ability to rise from a chair. In the elderly, a better knowledge of its determinants could lead to improve strategies for rehabilitation of this critical task.

Muscle phosphocreatine post-exercise recovery rate is related to functional evaluation in hospitalized and community-living older people

OBJECTIVE

to explore muscle mitochondria function with respect to age, functional status and nutrition in community-living and recovering hospitalized older subjects.

MEASUREMENTS

subjects were assessed for nutrition, hand-grip strength, 10-meter gait time, a modified timed get-up-and-go test and activities of daily living score (ADL). 31P magnetic resonance spectroscopy (31P MRS) was used to assess the initial rate of post-exercise phosphocreatine recovery (ViPCr) for mitochondrial function evaluation in 25 hospitalized older subjects (86.1 + 5.3 y) and in 25 community-living younger ones (74.5 + 6.2 y).

RESULTS

in multiple linear regression, longer time on the get-up-and-go test was independently associated with lower values of ViPCr (p = 0.008). For all subjects and in the 8 patients unable to perform this test, ViPCr was negatively correlated with the ADL score (respectively p < 0.001 and p = 0.025).

CONCLUSION

particularly in hospitalized and frail older subjects, muscle mitochondrial function was related to the global physical functional assessment.

Disability and quality of life in elderly people with diabetes

To implement preventive policies of disability in older diabetic people, the role of diabetes in the disablement process should be investigated. Diabetes mellitus is consistently associated with a higher prevalence of disability at all states, as well as with a progression in disability states and may be considered as a brake on recovery. This association is partially explained by existing complications, associated conditions (obesity, depression, arterial hypertension) treatment burden, and other social characteristics (lower income, lower educational level). Finally, in the disablement process, the role of altered muscle metabolism due to diabetes, aging, nutrition and sedentary lifestyle may represent a major target for interventions to improve functions and potentially activities in elderly people.
