French cross-cultural adaptation of the Organizational Readiness for Implementing Change (ORIC). BMC Health Serv Res 2019; 19:535. [PMID: 31366390 PMCID: PMC6668068 DOI: 10.1186/s12913-019-4361-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2019] [Accepted: 07/19/2019] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Organizational readiness is a factor known to influence the predisposition of individuals within an organization to change. Based on Weiner's organizational theory, the "Organizational Readiness for Implementing Change" (ORIC) questionnaire was developed and validated to measure organizational readiness in healthcare contexts. However, no such tools allow French-speaking organizations to measure this concept. The objectives of this study were to (1) conduct a French cultural adaptation of the ORIC questionnaire, and (2) initiate the study of its psychometric properties. METHODS (1) Cross-cultural adaptation and translation processes were first conducted with the methodologies of Beaton, Vallerand and Massoubre. (2) Subsequently, internal consistency was documented by calculating Cronbach's alpha and inter-item and item-to-scale correlations. The study of construct validity was initiated with a confirmatory factor analysis. RESULTS A French 10-item scale named the Réceptivité organisationnelle à l'implantation d'un changement (ROIC) was developed and pretested by 125 occupational therapists working in Quebec homecare services. Cronbach's alpha values for the 2 item subscales show satisfactory internal consistency (Commitment: α = 0.84 and Efficacy: α = 0.86). Inter-item correlations revealed that the ROIC's items are moderately related to each other while item-to-total scale correlations pinpoint items that accounts for variance and influence internal consistency. Confirmatory factor analysis allowed the initiation of a substantial documentation of ROIC's model fit with the original version (CFI = 0.89, TLI = 0.85, SRMR = 0.08, and RMSEA = 0.12). CONCLUSIONS The ROIC is a new theory-based and translated questionnaire that can be used to rigorously document the organizational readiness of French organizations. The ROIC has the potential to support members of different organizations in the identification of subsequent efforts for the implementation of a change.

Abstract
Little is known about the cost of home-based rehabilitation programs in Quebec, Canada. The objective of this pilot project was to test a cost estimation methodology in the context of rehabilitation services delivered at home and to provide preliminary data on the costs for lower limb orthopedic surgery patients. This pilot study examined a short-term home care program for adults, aged 65 and over who returned home after lower limb surgery and required rehabilitation services. Efficacy was determined as the functional autonomy changes between admission and discharge from home rehabilitation program, as measured by the functional autonomy measurement system (SMAF). Costs of professionals, including direct and indirect time related to the intervention, were also determined in order to document cost-effectiveness of the program. Eighteen subjects were recruited. From those, 14 had complete data available for the analysis. The result shows that costs related to the combined natural improvement and the effect of the home-based rehabilitation program were CAN dollars 419 per unit of change of functional autonomy. The results of this pilot study confirm the feasibility of the cost estimation methodology for a home-based rehabilitation program.

Abstract
The purpose of this study was to develop a subscale assessing social functioning for the functional autonomy measurement system (SMAF). The development of this new dimension was based on consultations (focus groups and nominal groups) of experts from different health care disciplines in Quebec, Canada, and France. Two interrater reliability studies were carried out with older people presenting a loss of functional autonomy and living either in an institution or at home. With the focus groups, the experts clarified the definition of social functioning and identified the factors involved. The nominal groups were used to construct a subscale composed of six items. The results of the first interrater reliability study showed a mean agreement percentage of 60% for the subscale and an intraclass correlation coefficient (ICC) of 0.70 (CI: 0.57-0.80). The results of the second interrater reliability study showed higher coefficients with an agreement percentage of 74% for the subscale and an ICC of 0.83 (CI: 0.61-0.93). These preliminary results demonstrate that the new social functioning subscale has good reliability, but more studies are needed to show its validity. The new SMAF, including the social functioning subscale, should help clinicians and researchers to obtain a comprehensive profile of functional autonomy. It could also contribute to the improvement of health care for older people.

Abstract
PURPOSE Many stroke survivors have to cope with impairments and disabilities that may result in the occurrence of handicap situations. The purpose of the study was to explore bio-psycho-social predictors of handicap situations six months after discharge from an intensive rehabilitation programme. METHODS At discharge from a rehabilitation programme, participants were evaluated with instruments measuring motor, sensory, cognitive, perceptual, affective and psychosocial impairments and disabilities that may play a role in the development of handicap. Some other demographic and clinical variables, and those related to rehabilitation, were also collected. Six months later, they were re-assessed in their own environment in order to document their handicap level with the Assessment of Life Habits (LIFE-H). RESULTS One hundred and thirty-two stroke patients participated in the discharge evaluation and 102 of them also participated in the handicap measurement. Relationships between handicap level and impairments and disabilities were all statistically significant. Multiple regression analyses indicated that affect, lower extremity co-ordination, length of stay in rehabilitation, balance, age and comorbidity at the end of an intensive rehabilitation programme are the best predictors of handicap situations six months later (adjusted R(2): 68.1%). CONCLUSIONS In spite of its exploratory nature, this study revealed that, among a substantial number of personal characteristics, some were more related to a handicap measure and have greater predictive value. Other studies should be carried out to validate these findings and to consider more environmental factors in order to better understand factors related to the development of handicap situations.

Abstract
BACKGROUND AND PURPOSE Having a stroke constitutes a major life event which engenders some types of adaptation in order to try to resume to a "normal" life. The objectives of this study were (1) to explore the type of coping strategies used following a stroke; (2) to verify if coping strategies change over time, and (3) to verify if the coping strategies used are related to age, gender, actualization of potential, handicap level and depression. METHODS A convenience sample of 76 participants who had had a stroke was recruited upon discharge from a functional intensive rehabilitation unit. Data were collected 2 weeks later and 6 months later in their own home. Coping strategies were measured using a modified version of the Ways of Coping Questionnaire. Actualization of potential was measured using the Measure of the Actualization of Potential and handicap level was quantified with the LIFE-H. Finally, the Beck Depression Inventory was used to evaluate the presence of depressive symptoms. CONCLUSION The results suggest that long after the end of an intensive rehabilitation programme, some coping strategies might be more effective in dealing with the consequences of a stroke whereas others might be related to some form of inadaptation. However, the results should be treated with caution. More research on coping following a stroke using mixed methodologies is needed.

Abstract
It is increasingly recognized that research is necessary to advance the practice of occupational therapy. The objective of this study was to determine whether occupational therapy departments in Quebec were commonly involved in research, and whether participation varied with the size of department and type of work setting. Secondly, enablers and barriers to participation in research were identified. A random sample of occupational therapy departments, stratified by size, were surveyed by mail. Participation rate was 74.8% (107/143). Participation in research was noted in half of the departments surveyed (51/107), most frequently as collaborator. Involvement in research was associated (p < .001) with a greater number of therapists in the department. Furthermore, occupational therapy departments in rehabilitation centres and in university hospitals were more likely to participate in research (79% and 90% respectively), whereas participation was lower for long-term care facilities (29%) and community health clinics (38%). When asked to rank factors that may facilitate participation in research, the highest rankings were given to: time allotted to research, research as a priority for administration, adequate financial support, and presence of an occupational therapy researcher and a research centre on site. This survey demonstrates that a number of factors can promote or prevent the realization of research activities within the clinical setting. Strategies are proposed to enhance the integration of research into clinical practice.

Abstract
Clozapine remains the most effective agent for diminishing or eliminating psychotic symptoms in treatment-resistant patients. However, among such patients, a small percentage (<3.0%) develops clozapine-induced granulocytopenia (CIG). In spite of the fact that lithium and granulocyte colony stimulating factor (G-CSF) have been shown to reverse CIG, many such patients are consigned to treatment with antipsychotic agents that have failed in the past. Apparently, their physicians are not aware that these patients can be salvaged for ongoing clozapine treatment. We report the effectiveness of lithium in reversing CIG in a young man with preexisting mild granulocytopenia. The rapidity of onset of leukocyte depletion is discussed in light of previously hypothesized autoimmune mechanisms of CIG. This case dramatizes the importance of lithium (or G-CSF) augmentation in those patients to maintain clozapine treatment so that their neutropenia can be reversed, and they can continue to benefit from the unique antipsychotic qualities of clozapine.

Abstract
BACKGROUND AND PURPOSE Little is known about the potential role of environmental factors in the handicap creation process following a stroke. The objective of this study was to explore the presence of a relationship between environmental factors and the occurrence of handicap following a stroke, taking into consideration age and the level of impairments and disabilities. METHODS This is a cross-sectional study where data were collected 6 months after discharge from an intensive functional rehabilitation unit. A convenience sample of 51 participants was recruited at the time of their admission to the rehabilitation unit for rehabilitation post-stroke. Perceived influence of environmental factors was measured using the Measure of the Quality of the Environment (MQE). Handicap situations were measured with the Assessment of Life Habits (LIFE-H). Impairments and disabilities comprised six domains (cognition, perception. depression, communication, sensorimotor function and comorbidity) assessed using a variety of measuring tools from which a composite score was derived. RESULTS Fifty-one participants aged 40-97 years old took part in this study. Perceived obstacles in the environment, together with age and the level of impairments and disabilities, explained 58.9% of the variation in the LIFE-H (handicap level). Taken alone, the perceived obstacles (total score) explained 6.2%. The perceived facilitators (total score) in the environment were not found to be related to the presence of handicap situations. CONCLUSION Increased level of impairments and disabilities. advanced age and perceived barriers in the physical and social environment contribute to the handicap creation process following a stroke.

Abstract
AIMS/HYPOTHESIS Healthy elderly people can have difficulties in precisely terminating gait due to age-related decline. Diabetes mellitus accelerates the neurodegenerative process, which results in an additional decline in motor control. This biomechanical study investigated goal-oriented gait termination in healthy elderly and elderly diabetic subjects. The trajectories of the centre of pressure and the centre of mass during the gait termination process were analysed in particular. It was hypothesised that the pathology results in an unstable gait termination, expressed in larger overshoots of the centre of pressure and the centre of mass than in healthy control subjects. METHODS A total of 15 subjects with Type II (non-insulin-dependent) diabetes mellitus with impaired foot sensitivity due to polyneuropathy (median, 66 years) were matched according to age, gender and body mass index with 15 healthy elderly subjects (median, 67 years). The participants walked at their own pace along the walkway and stopped in front of a marked stopping line while kinetic and kinematic data were recorded. RESULTS The diabetic subjects approached the stopping line more slowly (p = 0.002) than the healthy elderly subjects. They also exhibited a weaker maximal braking force (p = 0.011) and a prolonged relative time to develop this force (p = 0.023). Despite this slower motion, the centre of pressure overshoots were larger in the diabetic subjects than in the healthy elderly (p = 0.027). CONCLUSION/INTERPRETATION The results show differences between healthy elderly and diabetic subjects during easy goal-oriented stopping tasks. Changes in gait termination parameters and the increased overshoots in particular document the pathology-related decline in postural stability.

Abstract
OBJECTIVE The goal of this study was to determine the impact of a group activity program on the level of functioning of a person in instrumental activities of daily living (IADL). This program was specifically designed for people with mild cognitive deficiencies living at home and attending a day centre. METHOD Using a single subject design of AB type, eleven persons were assigned randomly to a experimental group (n = 7) and to a control group (n = 4). Their cognitive functioning was found to be between the 5th and the 25th percentile on the Modified Mini-Mental State Examination (3MS), which corresponds to stage 3 on the Reisberg Scale. The 18 week long multi-strategic program consisted of two weekly meetings of one and a half hours each. This program included physical exercises, psychomusical techniques, cognitive games and tasks related to IADL. The level of functioning of the subjects in their IADL was measured six times at home using the Assessment of Motor and Process Skills (AMPS), before, during and after the program. FINDINGS The data derived from each subject were presented as a graphical analysis. Following the application of the program, more of the participants, as compared to the control subjects, improved their functioning in terms of IADL. CONCLUSION The findings of this study suggest that it would be possible to use coping strategies in the early stages of cognitive deficits.

Abstract
The goal of prosthetic rehabilitation is to compensate for the loss of a limb by amputation by, in the case of a lower limb, encouraging walking, and to achieve the same level of autonomy as prior to the amputation. However, because of difficulties walking, elderly amputees may use their prosthesis to a greater or lesser degree or simply stop using it during the rehabilitation period. The objective of this research was to study factors such as physical and mental health, rehabilitation, physical independence and satisfaction with the prosthesis to understand why amputees use their prosthesis or not. The sample was composed of 65 unilateral vascular amputees 60 years old or over living at home. The information was collected from medical records, by telephone interview and by mail questionnaire. Prosthesis use was measured by a questionnaire on amputee activities developed by Day (1981). Eighty-one per cent (81%) of the subjects wore their prosthesis every day and 89% of this group wore it 6 hours or more per day. Less use of the prosthesis was significantly related to age, female gender, possession of a wheelchair, level of physical disability, cognitive impairment, poorer self-perceived health and the amputee's dissatisfaction. A multiple regression analysis showed that satisfaction, not possessing a wheelchair and cognitive integrity explained 46% of the variance in prosthesis use.

Abstract
The authors have studied the ability of glial cell line-derived neurotrophic factor (GDNF) to promote survival of human fetal dopaminergic tissue after a storage period of 6 days and subsequent implantation into the human putamen. The results indicate that GDNF promotes survival of stored dopaminergic cells. Cells stored without GDNF had a 30.1% decrease in survival time compared with those exposed to GDNF. Two patients with Parkinson's disease received bilateral putaminal implants of fetal dopaminergic cells exposed to GDNF for 6 days and showed enhancement of graft survival as assessed by positron emission tomography scanning. A mean increase of 107% in putaminal fluorodopa uptake from baseline values was observed 12 months postgrafting.

Abstract
The authors present a simple, reliable, and safe system for performing neural transplantation in the human brain. The device consists of a transplantation cannula and microinjector system that has been specifically designed to reduce implantation-related trauma and to maximize the number of graft deposits per injection. The system was evaluated first in an experimental rat model of Parkinson's disease (PD). Animals in which transplantation with this system had been performed showed excellent graft survival with minimal trauma to the brain. Following this experimental stage, the cannula and microinjector system were used in eight patients with PD enrolled in the Halifax Neural Transplantation Program who received bilateral putaminal transplants of fetal ventral mesencephalic tissue. A total of 16 transplantation operations and 64 trajectories were performed in the eight patients, and there were no intraoperative or perioperative complications. Magnetic resonance imaging studies obtained 24 hours after surgery revealed no evidence of tissue damage or hemorrhage. Transplant survival was confirmed by fluorodopa positron emission tomography scans obtained 6 and 12 months after surgery. As neural transplantation procedures for the treatment of neurological conditions evolve, the ability to deliver viable grafts safely will become critically important. The device presented here has proved to be of value in maximizing the number of graft deposits while minimizing implantation-related trauma to the host brain.

Abstract
This article presents the results of a study conducted to verify the test-retest and inter-rater reliability of the French version of the Ontario Society of Occupational Therapy (OSOT) Perceptual Evaluation. Designed to evaluate the perceptual deficits in patients with brain injuries, this tool uses a 5-points scale (0-4) to measure 18 different tasks. The scores obtained for each task are added to establish a total score. In the early 90s, the instruction manual of the OSOT Perceptual Evaluation was translated in French by a group of occupational therapists from l'Institut universitaire en gériatrie de Sherbrooke. To ensure the reliability of this version, a study was conducted to determine the test-retest reliability and the simultaneous inter-rater reliability. Thirty-two francophone subjects with brain injuries were each evaluated twice by the same therapist to determine the test-retest reliability of this tool. At one of the two encounters, a second therapist completed the score sheet to verify the simultaneous inter-rater reliability. The results show that, despite a few weak kappas' scores for certain tasks, the test-retest reliability and the inter-rater reliability of the total score were excellent (test-retest reliability: intra-class correlation coefficient = 0.93, with a confidence interval of 0.87 to 0.97; and inter-observer reliability: = 0.98, with a confidence interval of 0.97 to 0.99). The findings of this study show that the French version of the OSOT Perceptual Evaluation can therefore be used confidently by francophone occupational therapists.

Abstract
The objective of this research was to study age-related changes in the upper extremity performance of healthy community-dwelling elderly people, by using a longitudinal design. In 1995-1996. gross and fine manual dexterity, global performance, motor coordination, grip strength, tactile recognition, two-point discrimination, touch/pressure threshold, and tactile localization of 264 of the 360 subjects initially evaluated in 1992-1993 were reevaluated by using the same upper extremity measuring instruments. Those who did not participate (n = 96) were found to be significantly different from those who participated in the longitudinal study. Although the survivors were younger, more active, and perceived themselves in better health than the nonparticipants, their upper extremity performance significantly decreased in the 3-year period, with a few exceptions. In general, the decline was related to the initial score but not to age.

Abstract
The satisfaction of persons with lower-limb amputations towards their prosthesis constitutes a critical factor in the use of the prosthesis. In order to evaluate a person's satisfaction, the SAT-PRO, a self-administrated questionnaire was developed. The questionnaire includes 15 items developed on the basis of the most significant criteria used by the person when selecting a technical aid. These criteria were measured using an ordinal categorical four-level scale. The validation of the SAT-PRO was established from a sample consisting of 61 people with below-knee or above-knee amputations, aging from 60 years and older. The internal consistency of the instrument is high (Cronback's alpha coefficient is 0.90) and the test-retest reliability coefficient (0.97) indicates a very good consistency of the questionnaire over time. Simple and multiple correlations were used to evaluate construct validity. The degree of use of the prosthesis and the feelings of depression, amongst the measured variables, are the best indicators of the satisfaction of the amputees toward their prosthesis.

Abstract
The purpose of the study was to compare two research designs, namely the cross-sectional design and the longitudinal design, in the context of upper extremity performance and age-related changes. Upper extremity performance of 360 randomly recruited healthy, community-dwelling elderly persons was evaluated with reliable and valid sensori-motor tests. Three years later, survivors (n = 264) were reevaluated with the same tests. In many tests, cross-sectional and longitudinal designs were comparable for estimating the changes in upper extremity performance with age. However, in some tests, the decline with age using a cross-sectional design was underestimated. The upper extremity performance decline observed with the longitudinal design was larger than the decline predicted with the cross-sectional design. The withdrawal and survivor biases related to the longitudinal design and the cohort bias associated with the cross-sectional design may, in part, explain these results.

Abstract
Grip endurance is one of the important prerequisites for good performance of the upper extremity and hence it is important to evaluate it correctly. However, we know little about normal grip endurance, especially for elderly people. The main objective of this study was to examine the age-related changes in grip isometric endurance of healthy community-dwelling elderly people. Two-hundred and eighty-six subjects aged between 60 and 90, were randomly selected from the electoral list of the city of Sherbrooke, Quebec, Canada. Grip relative isometric endurance was evaluated using the Jamar dynamometer. Isometric grip endurance was estimated by the number of seconds a subject could sustain 50% of his/her maximal voluntary grip strength. Contrary to other upper extremity sensorimotor parameters, no grip isometric endurance difference was found with age, in spite of a slight tendency towards a decrease. The women tended to have better scores than the men and endurance of dominant hand is better than the non-dominant. The stability with age could be explained by muscle fiber composition modifications.

Abstract
BACKGROUND AND PURPOSE The main objective of this study was to compare the sensorimotor performance of the unaffected upper extremity (UE) of elderly stroke patients with that of healthy elderly people. METHODS The group of stroke patients was composed of 43 hemiplegic/paretic subjects who had had a cerebrovascular accident at least 6 months earlier. They were > or = 60 years old, were right-handed before the stroke, had visual perception within normal limits, and showed no major cognitive impairments. A group of 43 healthy subjects matched for dominance, age, and sex was used for comparison. The main parameters of the performance of the unaffected UE of the stroke subjects and of the same side of the healthy subjects were measured with valid, reliable instruments. Some variables potentially related to the unaffected UE were also measured: affected UE motor function, functional independence, length of time since the stroke, self-perceived health status, activity level, and hand anthropometry. RESULTS Statistical analyses showed significant deficits in the unaffected UE of hemiplegic/paretic subjects compared with normal subjects with regard to the following parameters: gross manual dexterity, fine manual dexterity, motor coordination, global performance, and kinesthesia (P < .01 to P < .0001). No significant clinical or statistical difference was found for grip strength (P < .81), static and moving two-point discrimination (P = .21 and P = .12), or touch/pressure threshold (P < .91). CONCLUSIONS Many factors (frequency of use of the unaffected hand, sensorimotor interaction tasks, severity of the deficits in corticifugal projections, and deficits in postural stabilization) could interact to provide the clinical picture obtained in the present study.

Abstract
OBJECTIVE To develop normative data for four hand sensibility modalities in older subjects. DESIGN Cross-sectional. SETTING AND PARTICIPANTS Three hundred and sixty community-dwelling subjects of both sexes, aged 60 to 94, randomly selected from the electoral list of the city of Sherbrooke, Quebec, Canada. MEASUREMENTS Touch/pressure threshold (Semmes-Weinstein monofilaments), static and moving two-point discrimination (Mackinnon-Dellon Disk-Criminator), tactile recognition (Modified Pick-up test), and thumb kinesthesia. RESULTS A reduction with age was found in the performance of the study subjects, with the exception of the kinesthesia test. The values obtained in this study are clearly lower than the norms proposed for adults, underlining the importance of using reference values developed for the target clientele. CONCLUSION The norms will help clinicians to differentiate better between normal and pathological changes in sensibility with age.

Abstract
OBJECTIVES Objectives of this study were to develop normative data for the Test d'Evaluation des Membres Supérieurs de Personnes Agées (TEMPA) and determine its relation to upper extremity sensorimotor parameters such as fine and gross dexterity, coordination, strength, endurance, range of motion, and several types of sensibility. DESIGN Cross-sectional study. SETTING Community-dwelling subjects. PARTICIPANTS Three hundred sixty healthy subjects randomly recruited by age and sex strata (60 to 69, 70 to 79, and 80 or older). MAIN OUTCOME MEASURES Length of execution of the tasks in the TEMPA. RESULTS Normative data are reported by gender and age group. The time taken to execute the tasks increased significantly with age. The women were faster on the tasks requiring a higher degree of fine dexterity, whereas the task requiring a lesser degree of fine dexterity and sensibility and more grip strength was accomplished faster by the men. Subjects who were more active and described themselves as being in excellent or good health performed better. CONCLUSION The norms will help clinicians differentiate better between normal and pathological aging in upper extremity performance.

Abstract
The Functional Autonomy Measurement System (SMAF) is an instrument designed to assess disabilities related to 29 functions with a four-point scale (from 0: independent to -3: dependent). For epidemiological studies, a total score and five sub-scores can be obtained. A revised version was developed adding a -0.5 level to many items to indicate an activity accomplished independently but with difficulty. The objective of the study was to verify the test-retest and inter-rater reliability of the total score and sub-scores of the SMAF. Ninety subjects were randomly recruited in nine different residential settings ranging from home to long-term-care hospitals. Half of the subjects were assessed by the same nurse within a 2-week interval (test-retest) and the other half were assessed twice by two different nurses within the same interval (inter-rater). Results show intra-class correlation coefficients (ICC) of 0.95 and 0.96 for the total scores on test-retest and inter-rater reliability, respectively. The ICC were over 0.74 for all sub-scores for both types of reliability. A small systematic bias was present for two SMAF subscores on the inter-rater reliability. The addition of a new level did not modify the reliability of the scale.

Comparison of the Jamar dynamometer and the Martin vigorimeter for grip strength measurements in a healthy elderly population. SCANDINAVIAN JOURNAL OF REHABILITATION MEDICINE 1995; 27:137-43.

Abstract
Grip strength is considered to be a good indicator of upper limb strength. The Jamar dynamometer and the Martin vigorimeter are two instruments frequently used to assess grip strength in clinical and research settings. The purpose of this study was to compare these instruments for assessing grip strength in 360 people aged 60 to 94 years, randomly selected from the electoral list. Anthropometric data were also collected. Data analyses were done using the maximum value on 3 trials with each instrument. Although the Martin vigorimeter is a pressure measure implying a dynamic movement as opposed to the static strength measure of the Jamar dynamometer, results indicate a very high correlation between the two measures. Grip strength measured by the Jamar dynamometer is even more dependent on hand anthropometry than measurements with the Martin vigorimeter.

Abstract
Manual dexterity is frequently evaluated in rehabilitation services to estimate hand function. Several tests have been developed for this purpose, including the Purdue Pegboard, which measures fine manual dexterity. The goals of the study were to verify the test-retest reliability with subjects aged 60 and over without upper limb impairment, and to develop normative data based on a random sample of healthy older community-living individuals. The results show that the test-retest reliability is good (intra-class correlation coefficients from 0.66 to 0.90, depending on the subtest). Norms are presented to help clinicians involved in rehabilitation services to better differentiate real dexterity deficits from those that may be attributed to normal ageing.

Abstract
OBJECTIVES Grip strength is an important prerequisite for good performance of the upper limb, hence it is important to evaluate it correctly. However, one of the main difficulties in evaluating the grip strength of elderly patients is the absence of valid norms. Therefore, the objective of this study was to develop normative data for maximum grip strength of persons aged 60 years and older. METHOD The grip strength of 360 subjects aged 60 years and older, randomly recruited by age and gender strata, was evaluated with the Jamar dynamometer and the Martin vigorimeter according to the protocol of the American Society of Hand Therapists. RESULTS Grip strength diminishes curvilinearly with age, and men are consistently stronger than women. The data are presented by the means, standard deviations, and range, and as predictive equations obtained by regression analysis. In addition to age and gender, hand circumference and body height proved to be the best indicators of grip strength for this population of elderly subjects. CONCLUSION The random recruitment of subjects, the high participation rate in the study, and the comparability of the subjects who agreed to participate and those who refused give this study the high external validity that is essential to any norm study. The predictive equations will help occupational therapists to better estimate the expected grip strength of elderly patients than they could if using only age and gender.

Abstract
Motor co-ordination is an important prerequisite to adequate upper-extremity performance. With the ageing of the population, more and more elderly people are at risk of acquiring upper-extremity motor inco-ordination following sensorimotor deficit. The main objective of the study was to develop normative data on upper-extremity motor co-ordination for elderly people. Three hundred and sixty subjects aged 60 and over were randomly selected and evaluated with the Finger-Nose Test. The results revealed a linear decline in the performance of this test with age. Younger, more active and subjectively healthier subjects presented better motor co-ordination. Some differences were found between sexes and sides. The normative data will help clinicians to identify pathological reduction in motor co-ordination in an elderly population.

Abstract
Grip strength is frequently measured in rehabilitation settings in order to monitor patient progress. Many factors influence grip strength measurements, including body segment positions and particularly elbow position. The objective of this study was to compare grip strength measurements obtained with two different elbow positions: full extension and 90 degrees of flexion. Forty-nine healthy right-handed men aged 60 to 84 years were tested with a Jamar dynamometer. Results indicated that left grip strength was significantly higher when the elbow was flexed to 90 degrees compared with when it was fully extended. No statistical difference between the two elbow positions was found for the dominant hand.

Abstract
Manual dexterity is a skill frequently evaluated in rehabilitation to estimate hand function. Several tests have been developed for this purpose, including the Box and Block Test (BBT) that measures gross manual dexterity. The goal of the present study was to verify the test-retest reliability and construct validity of the BBT with subjects aged 60 and over with upper limb impairment. The second objective of this research was to develop normative data based on a random sample of healthy elderly community-living individuals. The results show that the test-retest reliability is high (intraclass correlations coefficients of 0.89 to 0.97) and the validity of the test is shown by significant correlations between the BBT, an upper limb performance measurement and a functional independence measurement. The norms will help rehabilitation clinicians to differentiate better between real difficulties and those that may be attributed to normal aging.

Abstract
OBJECTIVES Dementia is the disease most frequently leading to admission in long-term care institutions, primarily because persons with this disease exhibit several behavioral problems. The objective of this study was to measure the efficacy of the sensory integration program developed by Ross and Burdick in improving the functioning of persons with dementia. METHOD Forty subjects with dementia (28 women, 12 men, mean age of 78.4 years) in three different institutional settings in Quebec City, Canada, were randomly assigned to the study (n = 22) or control (n = 18) group. Subjects in the study group participated in three 45-min sessions of a sensory integration program per week for 10 weeks. Outcomes were measured using the Revised Memory and Behavior Problems Checklist and the Psychogeriatric Scale of Basic Activities of Daily Living. RESULTS The sensory integration program had no significant effect on the behaviors of the study group. CONCLUSION Before this type of program is labeled inefficacious, other studies are necessary to determine whether modifying the frequency of sessions, the number of subjects, and the measuring instruments would lead to similar results.

Abstract
The aim of our study is to analyze the clinical features and outcome of digestive surgery in the aged. From Jan. 1979 to Dec. 1981, 1,389 operations under general anesthesia were performed on patients 75 years old and more. From this group, 163 patients (111 females and 52 males, mean age: 79 +/- 0.7 years) underwent surgery of the alimentary tract. The procedures were divided in: colorectal (48%), biliary (32%), gastric (10%), small bowel (6%), esophagus (1%) and others (3%). An operation for cancer was performed in 63 patients: palliative (69%), curative (31%). The mean length of hospital stay is 23 days (pre-op 7 days, post-op 16 days). Only 16% of the patients needed intensive care. Postoperative complications occurred in 43 patients (26%); cardiovascular (47%), psychiatric (26%), pulmonary (23%) and others (4%). The overall mortality rate is 10%: 6% for elective cases and 24% for urgent cases (49 patients). The mortality is related to: sepsis and peritonitis (53%), cardiopulmonary disease (23%), hemorrhage (12%), cachexia (12%). At discharge, 62% of the patients returned home directly, 18% to convalescent homes, 10% to unknown places and 10% in nursing homes. Our data supports the benefit of surgery in the aged.
