Abstract
This study examined the short-, mid-, and long-term effects of a motor and multisensory care-based approach on (i) the behavior of institutionalized residents with dementia and (ii) care practices according to staff perspective. In all, 6 residents with moderate to severe dementia (mean age 80.83 ± 10.87 years) and 6 staff members (40 ± 10.87 years old) were recruited. Motor and multisensory stimulation strategies were implemented in residents’ morning care. Data were collected with video recordings and focus-group interviews before, immediately after, at 3 months and 6 months after the intervention. The frequency and duration of each resident’s behavior were analyzed. Content analysis was also performed. Results showed short-term improvements in residents’ communication and engagement, followed by a sustained decline over time. Staff reported to change their practices; however, difficulties related to the institution organization were identified. There is a need to implement long-term strategies and involve institutions at different organizational levels to sustain the results.

Introduction
Dementia is associated with a progressive deterioration of cognitive functions, changes in behavior and communication problems, 1 , 2 and restrictions in mobility and self-care activities. 3 , 4 As the disease progresses, caring for these patients at home becomes an overwhelming task and care home placement tends to occur. 3 , 5
In residential care homes, the care provided to people with dementia is commonly task oriented, focusing on the instrumental activities of daily living (ADLs) and pharmacological treatment. 6 Currently, good care is associated with person-centered approaches, 6 which in the case of dementia care should include motor, social and multisensory stimulation (often neglected) tailored to each patient’s preferences and needs, 4 , 7 since it promotes psychosocial and physical activity, contributing to delay functional, cognitive and social decline.6–9
Multisensory stimulation (MSS) consists of actively stimulating the primary senses without the involvement of higher cognition processes. 10 This intervention has been found to decrease the frequency of behavioral problems and apathy, 11 , 12 improve residents’ communication 13 and interactions with staff, 10 , 14 and increase residents’ functional performance 15 and attentiveness to the environment. 16 Motor Stimulation (MS) is characterized by structured exercises known to stimulate mobility, improve balance and cognition, reduce falls and functional decline, 17 and delay the progression of the performance decline of ADLs in residents with dementia. 18
These stimulation-oriented approaches (MSS and MS) have been provided to people with dementia, 13 , 17–21 mostly by qualified staff and confined to specialized wards or nursing homes, 2 , 20 , 22 , 23 being scarce in the context of more traditional care homes (where in Portugal most people with dementia are institutionalized), with nonqualified staff. Furthermore, these studies did not examine the long-term effects.
Overall, care staff, who maintain the most direct contact with people with dementia, 24 have insufficient specialized training for providing them care. 25 , 26 Therefore, training care staff to meet specific competencies on dementia has been recommended to (i) improve staff knowledge and skills regarding dementia care 25 , 26 ; (ii) increase residents’ well-being, 27 and (iii) create opportunities for people with dementia to use their resources and abilities in their everyday lives. 28
There are still few research studies which have trained care staff with basic skills to implement MSS 29 or MS 13 in daily care provision to residents with dementia. Furthermore, a scarce number of studies have assessed the impacts of the interventions directly on the residents’ behaviors and on care practices considering staff’s opinions. Therefore, this study aimed to examine the short- (after the intervention), mid- (3 months), and long-term (6 months) effects of a motor and multisensory care-based approach on (i) the behavior of residents with moderate to severe dementia living in a residential care home and (ii) care practices according to staff perspective.
Methods
Design and Setting
A single-group repeated measures design was conducted in a residential care home, in the central region of Portugal. The care home met the following requirements: willingness and agreement to participate in the study, no substantial organizational changes during the study period, and no simultaneous participation in similar studies. The facility included 53 licensed beds for older people and, before the study began, there were 21 residents with a clinical diagnosis of dementia.
Participants
Residents with dementia
In all, 13 residents with dementia were identified by the physician of the residential care home to participate in the study, according to the following inclusion criteria: (1) presenting a clinical diagnosis of moderate to severe dementia, according to the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition; DSM-IV criteria) 30 ; (2) living in the care home for at least 2 months, so adjustments to the new people and environment had been performed; (3) requiring staff assistance during daily care activities; and (4) having no other psychiatric diagnosis. The legal guardian of each resident was contacted, informed about the study, and asked to sign the informed consent. In all, 8 legal guardians signed the written informed consent. However, 1 resident died during the implementation period and other was excluded for refusing to be assessed by video recordings. A total of 6 residents were thus recruited.
Residents (4 females) with a mean age of 80.83 ± 10.87 years (age ranged from 66 to 93 years old) and a clinical diagnosis of moderate to severe dementia participated in the study (Table 1). All participants had moderate to severe cognitive impairment, according to the cutoff scores of the Portuguese version of the Cognitive Impairment Test of the EASYcare. 31 The assessment of global functional ability with the Barthel Index 32 showed that 3 presented high levels of dependency in the ADLs performance, whereas the other 3 revealed moderate to slight dependency (Table 1).

Care staff
The service manager identified 10 eligible staff participants who maintained direct contact with the residents with dementia during daily care provision. Staff members who were only working at night were excluded as they were not involved in providing morning care. Potential participants were individually informed about the study purposes and invited to participate. Nine agreed to participate. Written informed consent was obtained. Prior to the start of the program, 3 members had to abandon the study (1 due to health problems, 1 for personal reasons, and 1 quitted the job). Thus, 6 staff members, all females with a mean age of 40 ± 11.91 years, ranging from 23 to 51 years participated in the study. Their academic qualifications were primary school (n = 1), 5 to 6 school years (n = 1), 7 to 9 school years (n = 1), secondary school (n = 1), and higher education (n = 2). Half of the sample was working at the care home for more than 3 years (on average 5 ± 5.99 years).
Motor and Multisensory Care-Based Approach
A training program was developed to provide staff with knowledge and skills to introduce MSS and MS to residents’ morning care routines. Morning care was chosen as the recent literature indicates that this is the period of the day where more interaction between staff and resident occurs
33
and problematic behaviors are more frequent.

Morning care was defined as the period of time between 07:00
Staff participants received eight 60-minute training sessions, 1 every other week, over a 4-month period. The training was performed in the care home by a multidisciplinary team, which included a gerontologist, a physiotherapist, and a psychologist. The topics of the sessions comprised myths and misconceptions related to dementia syndrome; staff-resident relationships and the importance of understanding the effects of dementia on social and self-care abilities of residents; the relevance of maintaining the remaining abilities and integrate MSS and MS strategies during the provision of personal care according to residents’ sensory stimuli preferences (which were collected by the research team dialoguing with the family and care staff); and verbal and nonverbal communication and other facilitative interaction aspects. The intervention has been presented and described in detail elsewhere. 35 All participants were given handouts which summarized the most relevant information and emphasized the person-centered care.
In the following 3 days after each session, the gerontologist and the physiotherapist assisted staff during the provision of morning care, clarifying doubts and making suggestions to help them implement the MSS (eg, using a fragranced shower gel or playing a relaxing music during the resident’s bath) and the MS strategies (encouraging the person to perform 1 task, or a part of it, eg, washing the arms, removing the foam from the body, by giving him or her small and simple instructions or physical guidance), according to what has been described in Cruz et al. 35 The individual assistance was provided as it has been considered essential to promote practice change 36 and sustain implementation of new knowledge. 2 , 26 , 37
Data Collection
Data were collected at baseline, immediately after, at 3 months, and 6 months after the training program.
Residents’ behavior
The short-, mid-, and long-term effects of the motor and multisensory care-based approach on the behavior of residents with moderate to severe dementia were studied through video recordings of morning care routines. In all, 24 video recordings were collected, 6 in each period of data collection. Prior to data collection, several video recordings were performed to minimize the effects of the camera in the behavior of staff and residents. 38 Furthermore, a rigorous protocol for data collection was defined in advance to minimize reactivity effects, the video camera was fastened to a top of a tripod, placed in the bathroom, and turned on before the resident entered the room; all staff members were instructed to inform the resident about the camera and to ask permission to record; staff members were also instructed to stop or remove the video camera if they noticed any resident’s negative reaction caused by the device presence.
Staff opinions about the motor and multisensory care-based approach
Focus group interviews were also conducted with 5 staff participants at 2 weeks, 3 months, and 6 months after the intervention. One participant missed all the interviews due to personal medical reasons. These interviews were semi-structured and aimed to obtain in-depth staff participants’ opinions about their care practices implementing a motor and multisensory care-based approach (ie, impacts on the care provided, suggestions for future interventions, and difficulties in implementing it into practice). Each interview lasted for approximately 2 hours and was audio-recorded and transcribed.
Data Analysis
Residents’ behavior was studied by analyzing the frequency and duration of a list of behaviors (ethogram). The ethogram was obtained from the previous research 29 , 39 , 40 and preliminary observations of the video recordings. The list comprised 4 categories (Table 2), caregiver-direct gaze, verbal communication, and task engagement (voluntary and solicited).
Categories of the Residents’ Behavior List.
The video footage was then selected for analysis. It was predefined that the observation time started when both resident and staff member appeared on the screen and it ended when they were both out of reach of the camera. Thus, to follow this criterion and to be able to compare the observational variables between the different participants and across the different phases of the intervention, the video recordings were cut so that all would have the length of the smallest video recording (211 seconds [3 minutes and 31 seconds]). In the longer video recordings it was pre-established that the start of the video recording analyzes would be the beginning of the observation time.
The video recordings were then analyzed by 2 independent observers. The observers rated the residents’ behaviors according to the ethogram using specialized software, Noldus The Observer XT 7.0 (Noldus International Technology, Wageningen, the Netherlands). They were previously trained to use the software by analyzing the video recordings obtained before data collection, and were blinded to the phase of the data collection (baseline, immediately after, 3 months, and 6 months after). The frequency and duration of the categories were measured for each resident in different phases.
Reliability of the observations
One of the major challenges to observational data is collecting reliable information. 41 Therefore, the study of the interobserver reliability was performed for the frequency and duration of each behavior in each phase, using the methods recommended for conducting reliability studies with continuous data, 42 that is, intraclass correlation coefficient (ICC) 43 using Equation (2.1), and the Bland and Altman method for assessing the agreement. 44
The ICC (2.1) values (Table 3) ranged between 1.00 and 0.444 for all categories except 2, indicating excellent to moderate reliability. 43 The lower ICC values, 0.283 and 0.377, were found for the frequency of the category voluntary engagement in the task (baseline) and for the frequency of caregiver-direct gaze (3-month follow-up), respectively.

Bland and Altman 95% limits of agreement were measured and the scatter plots were analyzed for all categories. A good agreement between the observers was found and no systematic bias was seen (see Table 3).
Effects of the motor and multisensory care-based approach on residents’ behavior
Descriptive and inferential analyses of the behavior categories were carried out using the PASW Statistics version 18.0 for Windows (SPSS Inc, Chicago, Illinois). The mean frequency and duration of each behavior category was calculated for the descriptive analysis. Differences between the phases of the data collection were analyzed using the nonparametric Friedman test (repeated measures for paired samples). A P value below .05 was considered statistically significant. To be able to measure effect size for each behavior category, Wilcoxon signed-ranks tests were calculated to compare each phase of data collection with the baseline. The equation used was r = |Z|/√N. 45 According to Cohen, 46 a cutoff of r ≥ .1 indicates a small effect, r ≥ .3 a medium, and r ≥ .5 a large effect.
Focus-group interviews
The transcripts were analyzed using qualitative content analysis. The texts were read repeatedly by 2 authors (second and third authors) who acted as independent judges to (i) construct a sense of the text as a whole, (ii) identify meaning units according to the aim of the study, and (iii) condensed the meaning units and clustered them into major categories. Thereafter, a formal meeting was held to compare individual analysis and to agree on final categories and subcategories. Critical feedback was performed by the other authors.
Results
Video Recording Findings
Table 4 presents the changes in residents’ behavior during morning care routines, in the 4 moments of data collection. It is possible to observe an increase in both frequency and duration of caregiver-direct gaze immediately after the intervention and at 3-month follow-up, with a medium effect size for both frequency and duration (r values ranged from .27 to .46); however, this interaction decreased almost to baseline levels after 6 months (r = .28). On the topic of verbal communication, there was a small increase in its frequency immediately after the implementation of the motor and multisensory care-based approach (r = .21), which was maintained 3 months after (r = .15). Nevertheless, the number returned to baseline levels after 6 months (r = .03). As regards to the duration of that behavior, it is possible to observe a sustained decline from baseline to 6-month follow-up (r values ranged from .04 to .21).

In terms of engagement, the results revealed an increase in residents’ involvement in morning care tasks immediately after the intervention, showing a moderate effect of the intervention (r frequency = .37; r duration = .35). However, this involvement was not maintained over time (r frequency = .27 and r duration = .15 3 months after the intervention; r frequency = .27 and r duration = .27 6 months after). Regarding the category solicited engagement in the task, it is noticeable a great increase in the frequency of that behavior in the post-intervention phase ( r = .35), with a similar decrease 3 months after the intervention (r = .28) which was sustained at 6-month follow-up (r = .19). Still, the duration of that behavior was improved after the intervention and maintained at 3-month follow-up (r = .27 and r = .21 immediately after and 3 months after the intervention, respectively). Nevertheless, the improvement was not observed 6 months after the end of the motor and multisensory-based approach (r = .27). With regard to the residents’ voluntary engagement, it found an improvement in both frequency and duration at the post-intervention phase; a large effect size was found for the duration, r = .53, but not for the frequency, r = .11. Although, a sudden decline was found at 3-month and 6-month follow-up to lower values than the observed at baseline (r values ranged from .23 to .43), no statistically significant differences between the phases were found for any behavior category.
Figure 1 provides information about the percentage of the duration of residents’ engagement in the total observation time of each video recording (ie, 211 seconds). It is possible to observe a considerable increase in the overall engagement in morning care tasks immediately after the intervention (nearly to 10%). However, the 3-month and 6-month follow-up revealed a reduction in residents’ involvement into the values below the baseline levels (from 19.70% at the baseline to 14.30% at 6-month follow-up).

Focus-Group Interviews Findings
From the analyzes of the focus-group interviews several subcategories emerged from the major categories established a priori (ie, impacts of the motor and multisensory care-based approach on the staff care practices, suggestions for future programs, and difficulties in implementing it into practice). An overview of these analyzes over time with examples of staff’s reports can be seen in Table 5.

a The gray shade shows when each category emerged.
Impacts of the Motor and Multisensory Care-Based Approach on Staff Care Practices
Some impacts were sustained over time. The staff perceived that the training program allowed them to: (i) demystify preexistent beliefs associated with dementia; (ii) be more conscious to person-centered care, and (iii) be able to implement the new acquired knowledge into practice (eg, active participation, multisensory stimulation, and communication skills). However, only in the focus group conducted 2 weeks after the program, participants reported to be (i) more aware of the impact of implementing the acquired skills on all residents’ well-being (not only those with dementia), (ii) able to reflect about their practice, and (iii) motivated to improve their practice.
Suggestions
Grief was suggested as a new theme to be explored in the future programs. Staff also considered that it would be important to conduct the program with the new admitted colleagues. This was mentioned at 3 and 6 months after the program.
Difficulties
The lack of time and human resources were identified in all focus groups as the major barriers to implement the strategies. In addition, the lack of availability to help was also mentioned at 6 months. In the last focus group, the lack of managers’ support was highlighted as a considerable constraint to the implementation of the intervention.
Discussion
The results showed a trend toward positive short-term effects of the motor and multisensory care-based approach on residents’ behaviors; however, no statistical significant differences were found. The frequency and duration of all behavioral categories increased immediately after the program, with the exception of verbal communication duration. An increase of almost 10% was observed for the duration and frequency of the total engagement of residents in the morning tasks at this point of time. Therefore, this study shows that it is very likely that staff has a significant role in stimulating residents’ verbal and non- verbal communication as well as their engagement in tasks. Similar findings have been found previously. 29 The exception found for verbal communication duration might be explained by the fact that, during the training, staff was encouraged to stimulate residents’ engagement in daily tasks and be aware of the nonverbal communication as an effective way to communicate with these residents. The increase in the frequency and duration of caregiver-direct gaze and residents’ engagement in the task also supports the idea that residents were receptive to the staff’s orientations and were engaging with the environment and therefore, their verbal communication decreased. Engaging residents with dementia in constructive and meaningful activities (eg, brushing their hair, dressing their clothes) has been shown to be beneficial in increasing positive emotions for preventing loneliness, boredom, and problematic behaviors associated with dementia, and improving ADLs and daily function. 47 These promising results may ultimately be translated in residents’ increased mobility and improvements of psychosocial aspects 6 and general quality of life 47 , 48 on day-to-day basis.
However, the duration and frequency of all behavior categories analyzed decreased over time. The declines were already observed at 3 months and levels equal or even below baseline were observed at 6 months. The results from the focus-group interviews might help to interpret these findings. Staff reported to continue to demystify preexistent beliefs associated with dementia, implement the new acquired knowledge, and be aware for the person-centered care. However, simultaneously the lack of: (i) time and resources, (ii) availability to help, and (iii) managers’ support; were identified as the main difficulties to implement the motor and multisensory care-based approach. The time commitment during the morning care to implement this type of interventions has already been raised. 29 However, in dementia care there are only a few moments where real individual contact between residents and staff can occur 29 and morning care is probably the longest and the most important in traditional care homes. In this study, this was not objectively quantified; however, staff were questioned about this aspect and did not perceive that the time needed for morning care had increased due to the intervention. Furthermore, staff reports to continue to implement the new acquired knowledge; however, the results from the video recordings do not confirm this finding. Social desirability might explain this discrepancy.
Therefore, managers should be aware that, although it is important that the staff access formal training on dementia, training alone cannot transform staff’s practices. If the training is to make any sustained impact, it needs to consider care staff experiences 49 and be supported by managers. 50 Managers can, for example, give clear and constructive feedback on care practice, or make sure that staff have enough time to support residents to maximize the use of their own abilities in personal care tasks, 50 which will contribute to sustain results over time. In sum, achievements will only be consolidated if other hierarchical levels besides staff are also involved as they will be the ones to legitimate the introduction of new practices.
Developing the intervention with the new colleagues and adding the theme “grief” were the 2 aspects suggested for future training programs. These suggestions lead us to interpret that the high turnover problematic and the importance to manage emotions should be considered and dealt directly in the training programs. These aspects are well described in the literature, however, often neglected in the design of training programs.
Strengths and Limitations
In this study the effects of the motor and multisensory care-based approach were examined directly on the residents’ behaviors; however, staff opinions were also considered to interpret the findings and inform the development and implementation of future training programs. This leads to a more complete, authentic, and rich exploratory data. 51 This is particularly important as in moderate/severe dementia, the only viable alternative (to measure residents’ well-being) is the direct observation of behavior 39 , 52 and ultimately, the goal of staff training is to improve the care provided to residents with dementia, helping staff translating learning into practice. 49 Therefore, care staff opinions are crucial for the development and implementation of innovative approaches and change in care practices.
Furthermore, few studies have implemented MSS and MS interventions in the residents’ natural contexts 29 but, have used instead special snoezelen rooms 53 , 54 or specific exercises to improve cognitive or physical function, 17 which were added as extras to the residents’ daily routine. This research supports that MSS and MS interventions can be implemented by trained care staff, on a daily routine (bedside, bathroom, etc) and in meaningful activities (brushing the teeth, showering), which facilitates its implementation in institutions with little resources and potentiates its routine use.
Our findings suggest that if MSS and MS are implemented by staff on a daily basis, 29 , 55 according to a person-centered care, considering resident’s preferences (which in this study was obtained dialoguing with the family and staff), it is possible to encourage and improve resident’s communication and engagement.
The few studies that have trained staff to implement MSS 29 MS 13 in daily care provision to residents with dementia had very different durations and yet all reported short-term positive benefits for the residents and/or staff. However, the long-term effects were not examined or in this study were found to deteriorate over time. Therefore, it can be hypothesized that it is not so much the intensity of the intervention (as long as a structured and organized training is provided) that will make a difference, but other strategies need to be explored to help to sustain results such as frequent close follow-up sessions, which will probably need to be a part of each institution policy. This emphasizes the need of involving the organizations as a key element for changing practices, also in dementia care. The role of education and training in care homes and the complexity of promoting and sustaining change has been thoroughly approached by Nolan and his coworkers, 56 however, relatively ignored in the clinical practice. Therefore, not involving the whole organization at its different levels has been a limitation which needs to be acknowledged in this study. Future research should consider this aspect carefully.
Other limitations have to be acknowledged. Given the small sample size, sufficient power was lacking to statistically confirm the differences between the phases; however, effect size for each variable was calculated. Future research with a larger sample, with a control group to provide comparisons, monitoring the organizations, and providing close follow-up sessions is recommended.
