Stroke is among the leading causes of morbidity and long-term disability in high-income countries. In Russia, the incidence of stroke is 3–4 cases per 1,000 population. Survival has improved to 85% in the past few years; currently, there are over 1,000,000 stroke survivors living in Russia, of whom 80 percent are disabled. So, post-stroke rehabilitation is becoming increasingly important for economy and society [1–6].
Stroke is a life-changing event both at the individual and community levels. Its sequelae prevent the patient from returning to work, lead to social isolation and are a heavy burden for economy [3, 5, 7, 8].
It is known that stroke can have a long-lasting impact on personal, familial and social well-being that persists after primary rehabilitation. Patients and their caregivers need access to rehabilitation resources and services [9–14]. Medical and social care is provided by healthcare specialists, social workers and volunteers [7, 8]. Highly-skilled medical professionals provide effective care in the early rehabilitation period. Then, other rehabilitation specialists step in to assist patients in social adaptation and relearning self-care skills.
What is known about the needs of stroke survivors and their caregivers is usually known from clinical data and observational studies which analyze a number of parameters using mostly non-standardized methods. That said, such data are sufficient to highlight some important problems, including social and emotional consequences of stroke that persist for many years after the initial event [15–20].
Considering the recent initiatives of public health agencies aimed at fighting the effects of stroke on individual and public health, it would be interesting to analyze the outcomes of social rehabilitation programs for stroke survivors through the medical and social lens and to estimate the sensitivity of the methods used to assess the functional state of stroke patients.
The aim of this study was to demonstrate the effectiveness of standardized post-stroke rehabilitation for patients with moderate impairments.
METHODS
This prospective randomized controlled parallel-group study was conducted at Kamyshin City Hospital № 1, Volgograd region, between 2016 and 2020. The study enrolled 122 stroke survivors with moderate impairments: 71 women (58.2%) and 51 men (41.8%). The mean age of the participants was 66.5 ± 12.8 years.
The following inclusion criteria were applied: both sexes, age between 18 and 85 years, moderate stroke within 6 previous months. Patients with severe stroke, brain tumors, somatic pathology, or psychiatric disorders were excluded from the study.
The patients were divided into 2 groups based on the type of rehabilitation program:
- group 1 (the comparison group) consisted of 59 patients undergoing standard rehabilitation;
- group 2 (the main group) consisted of 63 patients participating in the rehabilitation program proposed by the authors of this paper.
Patients included in the study were moderate stroke survivors in the late rehabilitation period. The average NIHSS score was 11.75 points. During the study, both groups received 10 sessions of physical exercise, 10 sessions of massage, 10 sessions of physiotherapy, 2 sessions of occupational therapy, and 1 session of social adaptation. Additionally, the main group received 5 sessions of occupational therapy, 5 sessions of social adaptation and 5 sessions of self-care skills.
Progress was evaluated using assessment scales for measuring functional, cognitive, psychoemotional status and social activity. Assessments were made before rehabilitation, after discharge from the hospital, i.e. 12–14 days after admission, and then at 1,3 and 6 months.
Before rehabilitation, all patients underwent a medical checkup and a neurological examination. The following assessment tools were used in the study: the Barthel Index, the Rivermead Mobility Index, the DASH questionnaire, the Beck Depression Inventory, the MMSE questionnaire, and the SSQoL score (Stroke Specific Quality of Life).
Social and medical rehabilitation of stroke survivors
For the purpose of this study, we designed a social rehabilitation program for stroke survivors. Unlike standard rehabilitation, the amount and type of interventions included in our program varied depending on the stroke sequelae experienced by the patient. The program was designed to fulfill the needs of stroke survivors with moderate impairments. The rehabilitation plan included social adaptation sessions conducted once a month, followed by the analysis of goal achievements. During the session, the patients were tested using the assessment tools listed above. Once every 2 weeks, we called the patients on the phone to check their adherence to the program and modify the tasks if necessary.
Each patient received a detailed written description of the rehabilitation program, with a daily planner for ticking the tasks performed during the day. The following skills were trained: using the bathroom and doing morning hygiene (independently, daily), taking a bath with minimal assistance, getting dressed with minimal assistance, doing up the buttons, tying shoelaces (independently). As part of their rehabilitation, the patients were asked to do simple cooking (make a sandwich or fried eggs) or try more challenging dishes (salad, soup) and do the dishwashing.
Physical activities included in the rehabilitation program were as follows: indoor walking over 200 m, going up and down the stairs, taking a walk outside, doing easy chores (bed making, dusting) or more difficult chores (mopping), gardening, taking care of indoor plants. Social activities included in the program were as follows: visiting family and friends, going to the cinema or theater, and hobbies (drawing, playing chess). We called the patients twice a month to evaluate their progress.
Statistical analysis was carried out in STATISTICA 10 (Statsoft; USA). Mean values and the standard error of the mean were calculated for quantitative parameters. Intergroup comparisons were done using the nonparametric MannWhitney U test, accounting for the specific character of the analyzed parameters. Differences were considered significant at p > 0.05.
RESULTS
The Barthel Index (independence) measured immediately after hospital treatment was higher than on admission. However, there were no significant differences between the groups: 72.7 ± 4.1 vs 72.1 ± 5.5 points for groups 1 and 2, respectively. BI dynamics were positive in both groups after discharge home and at 1, 3, and 6 months, with no significant difference between the groups (fig. 1). Before rehabilitation, the NIHSS score was 11.4 ± 4.0 in group 1 and 12.1 ± 5.0 points in group 2, with no significant difference between the groups.
Three months after the rehabilitation program was commenced, the Rivermead Mobility Index increased to 8.4 ± 0.4 in the main group (p = 0.011); at 6 months, it was 8.4 ± 0.5 (fig. 2). At both time points, the main group scored significantly higher than the comparison group (p < 0.05).
At 3 months, the DASH score declined to 68.1 ± 2.9 points in the main group and was statistically lower (p < 0.001) than in the comparison group (80.1 ± 5.2). At 6 months, the situation was the same: 81.4 ± 6.4 points in group 1 vs 66.2 ± 3.1 points in group 2 (p = 0.015) (fig. 3).
In the comparison group, the Beck Depression Inventory score declined to 15.3 ± 1.8 points at 3 months. The score was significantly lower in the main group (p = 0.008), equaling 12.7 ± 1.6 points. At 6 months, the situation was the same: group 1 scored 15.8 ± 1.4 points, group 2 scored 13.1 ± 0.9 points (p < 0.001) (fig. 4).
Before rehabilitation, the total MMSE (cognition) score was 20.5 ± 1.5 points in group 1 vs 20.0 ± 1.8 points in group 2. During the follow-up period, this parameter was slightly increasing slightly, with no significant difference between the groups (fig. 5).
Before rehabilitation, both groups were comparable in terms of all SS-QoL (quality of life) domain scores (table). At 6 months, the main group scored higher on most domains than the comparison group. For example, group 1 scored an average of 2.60 ± 0.17 points on the “energy” domain, whereas group 2 scored 3.07 ± 0.15 points, which was a significantly higher value (p < 0.05). The main group scored significantly higher on the “family roles” domain than the comparison group, but the “language” score did not differ significantly between the groups. The “mobility” score was significantly higher in group 2 than in group 1 (4.31 ± 0.29 vs 2.92 ± 0.37 points; p < 0.05).
The following scores were significantly higher in the main group than in the comparison group (p < 0.05): mood (4.34 ± 0.41 vs 2.85 ± 0.28), self-care (4.70 ± 0.19 vs 3.82 ± 0.20), social roles (3.82 ± 0.25 vs 2.74 ± 0.17), work, productivity (3.20 ± 0.28 vs 2.41 ± 0.15), upper extremity function (4.03 ± 0.19 vs 4.74 ± 0.21).
Vision, thinking and personality scores did not change in comparison with the baseline values in both groups.
The analysis shows that the proposed rehabilitation program was effective in helping stroke survivors recover important social skills: families started paying more attention to their stroke-affected members, patients became less dependent on their families. Repetitive self-care training makes the patient more active, reduces functional dependency on family members, and restores the patient’s role in the family. Regular meetups with friends and social activities improve social integration. As part of the rehabilitation program, we spoke with our patients on the phone once every two weeks over the course of 6 months and had social adaptation sessions once a month, which allowed us to control adherence to the program and task performance (going for a walk, meeting friends, gardening, hobbies). Regular control and active involvement of relatives in rehabilitation improved social activity of the patients indicated by increased SS-Qol scores.
At 6 months, the dynamics of the studied parameters were more pronounced in the main group than in the comparison group, as seen from the significantly higher Rivermead Mobility Index, higher SS-QoL scores and lower DASH and Beck scores.
DISCUSSION
Today, most experts hold the opinion that recovery of functions affected by the stroke, adaptation to the loss of such functions and social integration should be a top-priority in the rehabilitation of stroke survivors [20–23]. Therefore, it is essential to understand the needs of stroke survivors and challenges they face in order to develop effective approaches involving high-quality medical care and social work services [24–27]. When evaluating the quality of care, it is important to receive a feedback from the patient and their caregiver about the quality of care and to clarify what could be improved.
Our findings are consistent with the results of other studies reporting the mitigating effect of social work services on stress levels and the consequences of stress in stroke survivors [25, 26]. In spite of almost zero gains in functional independence, participation of stroke survivors in social activities increases their subjective satisfaction and quality of life [27, 28].
Effective post-stroke rehabilitation requires a multifaceted multidisciplinary approach. According to the literature, rehabilitation is more effective when the patient’s experience and feedback are taken into account. Active participation of the patient is important for establishing positive relationship between the patient and the therapist and for ensuring that there is no breach of ethics, especially in patient-oriented rehabilitation programs [26, 28].
In Russia, many rehabilitation facilities for neurology patients provide social rehabilitation services. They offer complex rehabilitation programs for the disabled that include social integration; this improves social adaptation, allows them to take vocational training and find a new job [14, 21].
CONCLUSION
The standardized program for medical and social rehabilitation of stroke survivors with moderate impairments was effective in terms of its clinical, psychological and social outcomes. The scales and inventories used in the study (specifically the Rivermead Mobility Index, DASH and the SS-QoL questionnaire) are sensitive to changes in the functional state of stroke patients with moderate impairments. More initiatives are needed to raise awareness and provide consultations on post-stroke adaptation, organize social, cultural, sports and educational events. It is important to conduct studies that provide the rationale for and refine the systemic approach to planning and implementing social support services for stroke survivors. Using such approaches in rehabilitation practice will increase the level of social support for stroke survivors, help them to recover the affected functions, encourage patients to actively participate in social activities and thus improve patient outcomes.
