RESNA position on the application of dynamic seating

Dynamic Seating is an intervention used as a part of a manual or power wheelchair to provide movement against resistance in response to client force. This technology can be used for various clinical applications including preventing client injury and equipment breakage; dissipating extensor forces; providing movement for sensory input, calming, and increased alertness; increasing muscle strength, trunk and head control; and other medical benefits. The purpose of this RESNA Position Paper is to provide a definition for this technology in relation to other seating and wheeled mobility technologies as well as present clinical indicators for this seating intervention including literature to substantiate these claims. Although more recent and stronger evidence is needed, existing research does support the application of dynamic seating in numerous clinical scenarios.

Clinical changes as a result of dynamic seating in a young adult with cerebral palsy

PURPOSE

This case study follows a single participant with cerebral palsy through 15 years of wheelchair seating interventions. Positioning challenges within the wheelchair seating system included significantly increased muscle tone, extension patterns, extraneous movement, loss of body position in relation to the seating system, loss of alignment with other assistive technologies, high energy expenditure, client injury and pain, and equipment damage. The purpose of this article is to present clinical changes seen in this participant during a progression of dynamic seating interventions.

CASE DESCRIPTION

includes four separate seating and wheeled mobility evaluations over an eight-year time frame and subsequent equipment recommendations. A key intervention was the application of dynamic seating. No standardized assessments for wheeled seating and mobility evaluation are available, at this time.

OUTCOMES

the recommended interventions resulted in reduced extension patterns, extraneous movement, loss of position and alignment with other assistive technologies, energy expenditure, client injury and pain, and equipment damage. Further, functional gains and increased seating tolerance were noted.

CONCLUSION

dynamic seating may address numerous positioning challenges in clients with increased muscle tone in conjunction with an appropriate seating system and mobility base.IMPLICATIONS FOR REHABILITATIONDynamic seating may:•Dissipate client forces to reduce active extension.•Protect a client from injury by reducing intermittent and sustained forces.•Protect wheelchair seating, mounting hardware, and the frame from loss of alignment and damage.•Provide movement to decrease agitation and increase alertness.

Effect of Nordic Sensi® Chair on Behavioral and Psychological Symptoms of Dementia in Nursing Homes Residents: A Randomized Controlled Trial

BACKGROUND

Behavioral and psychological symptoms of dementia (BPSD) are present in most people with dementia (PwD), including Alzheimer's disease. There is consensus that non-pharmacological therapies represent the first line of treatment to address BPSD.

OBJECTIVE

We explore the efficacy of the use of a rocking chair (Nordic Sensi® Chair, NSC) in the treatment of BPSD in nursing home residents with moderate and severe dementia.

METHODS

We carried out a 16-week randomized, single-blind, controlled, clinical trial with PwD admitted to nursing homes. Participants were assigned to a treatment group (n = 40) that received three times a week one session per day of 20 minutes in the NSC and a control group (n = 37). The Neuropsychiatric Inventory-Nursing Home (NPI-NH) was used as primary efficacy outcome. Occupational distress for the staff was evaluated using the NPI-NH Occupational Disruptiveness subscale (NPI-NH-OD). Statistical analyses were conducted by means of a Mixed Effects Model Analysis.

RESULTS

Treatment with the NSC was associated with a beneficial effect in most of BPSD, as reflected by differences between the treatment and control group on the NPI-NH total score (mean change score -18.87±5.56 versus -1.74±0.67, p = 0.004), agitation (mean change score -2.32±2.02 versus -0.78±1.44, p = 0.003) and irritability (mean change score -3.35±2.93 versus -1.42±1.31, p = 0.004). The NPI-NH-OD total score also improved the most in the treatment group (mean change score -9.67±7.67 versus -7.66±6.08, p = 0.003).

CONCLUSIONS

The reduction in overall BPSD along with decreased caregiver occupational disruptiveness represent encouraging findings, adding to the potential of nonpharmacological interventions for nursing home residents living with dementia.

Complex Clinical Intersection: Palliative Care in Patients with Dementia

Because of the rapidly growing older population and increases in longevity, rates of dementia have been rising. Clinical challenges of treating dementia include limited resources and lack of curative therapies. Palliative care approaches improve quality of life and alleviate suffering for dementia patients at the end of life, although implementation may be limited by societal acceptance and feasibility. This review examines the published literature on pain assessments, pain and behavior interventions, tools for advanced care planning, and clinical concerns in dementia patients. Ultimately, modification of the traditional palliative care model may improve outcomes and functioning for dementia patients at all stages of their illness.

Implementation of Rocking Chair Therapy for Veterans in Residential Substance Use Disorder Treatment [Formula: see text]

BACKGROUND

Substance use disorder (SUD) and mental health diagnosis negatively affect Veteran homelessness.

OBJECTIVE

Assess the acceptance and feasibility of rocking chair therapy as a self-implemented intervention for mood and substance cravings.

PICOT

For homeless Veterans in SUD treatment, how does adding vestibular stimulation by use of a rocking chair compared with treatment as usual affect levels of anxiety and substance cravings?

RESULTS

Two significant findings were observed. First, a greater number of minutes spent rocking was associated with significantly greater scores on the Expectancy scale of the Alcohol Craving Questionnaire (ACQ; p = .05), suggesting participants experiencing higher urges and desires to drink rocked to self-soothe. Second, a significant association was observed between a greater number of minutes spent rocking and lower scores on the ACQ Purposefulness subscale ( p = .03), indicating greater time rocking was associated with fewer urges and desires that are connected with the intent and plan to drink.

CONCLUSION

Vestibular stimulation by rocking in a rocking chair may increase the ability to self-regulate mood and substance cravings, thereby potentially reducing risk of relapse and recurrent chronic homelessness.

Interventions targeting pain or behaviour in dementia: a systematic review

BACKGROUND

Both pain and challenging behaviour are highly prevalent in dementia, and multiple studies show that some of these behaviours may be correlated. Pain, especially in non-communicative patients, can cause challenging behaviour, and treatment of pain therefore may have an effect on behaviour. This review aims to provide a comprehensive overview of the current state of evidence regarding the effectiveness of interventions targeting pain on the outcome behaviour, and interventions targeting behaviour on pain, in dementia.

METHOD

PubMed (MEDLINE), EMBASE, COCHRANE, CINAHL, PsychINFO and Web of Science were searched systematically. Studies were included if they focused on an intervention targeting a reduction in the person's distress, pain, and/or behaviour, and included adults with a main diagnosis of dementia.

RESULTS

Of a total of 893 potentially relevant publications that were identified, 16 publications met the inclusion criteria and were eligible for further analysis; 6 studies focused on a pain intervention targeting behaviour, 1 study focused on a behavioural intervention targeting pain, and 9 studies focused on an intervention targeting both pain and behaviour.

CONCLUSION

Available evidence suggests that (pain) interventions targeting behaviour, and (behavioural) interventions targeting pain are effective in reducing pain and behavioural symptoms in dementia.

Influence of Seated Rocking on Blood Pressure in the Elderly: A Pilot Clinical Study

Patients with Alzheimer’s disease (AD) who rock for 1—2 hr per day in a rocking chair demonstrate significant improvements in depression, anxiety, and balance and a decrease in pain medication usage; however, the underlying basis for their responses remains unclear. Rocking with plantar flexion uses the calf muscles, enhancing lower limb fluid return to the heart, which should increase blood pressure (BP) and may, then, also increase cerebral perfusion. Accordingly, we tested the efficacy of rocking activity for increasing BP in healthy, older persons. In a pilot laboratory study of 24 healthy, White men and women aged 55—87 years, we observed that 30 min of steady rocking led to an average 12 mmHg increase in systolic blood pressure (SBP, p < .001) and a 3.6 mmHg average increase in diastolic blood pressure (DBP, p < .001). To determine the effect of using this intervention in a nonclinical setting, we tested a similar group of 7 participants at a senior center. In this setting, we observed an average increase in SBP of 27 mmHg (p < .001) and in DBP of 2.5 mmHg (p < .001) after 30 min of rocking. In a subgroup (n = 8) of hypotensive individuals (SBP < 110 mmHg after sitting quietly for 30 min) extracted from both settings, rocking raised the average SBP from <100 mmHg to approximately 120 mmHg. These results are consistent with the hypothesis that rocking can increase BP and, therefore, may enhance cerebral perfusion. This observation may play a fundamental role in designing nursing interventions focused on improvement of symptoms associated with AD.

Psychosocial treatments of psychological symptoms in dementia: a systematic review of reports meeting quality standards

BACKGROUND

This paper provides a systematic review of selected experimental studies of the effectiveness of psychosocial treatments in reducing psychological symptoms in dementia (e.g. anxiety, depression, irritability and social withdrawal).

METHOD

English language reports published or in press by February 2008 were identified by means of database searches and checks of previous reviews. Reports were appraised with respect to study design, participants' characteristics and reporting details. Because people with dementia often respond positively to personal contact, studies were included only if control conditions entailed similar levels of social attention or if one treatment was compared with another.

RESULTS

Only 12 of 48 relevant papers met every specification. Treatments proved more effective in reducing psychological symptoms than an attention control condition or another treatment in only six of the 12 selected studies. Interventions with moderate effect sizes included music and recreation therapy.

CONCLUSIONS

Some psychosocial interventions appear to have specific therapeutic properties, over and above those due to the benefits of participating in a clinical trial. Their effects were generally modest with an unknown duration of action. This limited efficacy suggests that treatments will work best in specific, time-limited situations, tailored to individuals' requirements. There is no preferred method to rate psychological symptoms.

Overview of Alzheimer's disease

In conclusion, many researchers from multiple disciplines are addressing AD at many levels, ranging from prevention, to cellular alterations, to treatment modalities, and coping and care giving with the consequences of the ravages left by the disease. Although much has been learned in the last several decades of active research, much remains to be learned. In its current status, AD is a chronic disease without a cure, which provides ample opportunities for nursing management throughout the course progression.

Effects of behavioral interventions on disruptive behavior and affect in demented nursing home residents

BACKGROUND

Disruptive behaviors are prevalent in nursing home residents with dementia and often have negative consequences for the resident, caregiver, and others in the environment. Behavioral interventions might ameliorate them and have a positive effect on residents' mood (affect).

OBJECTIVES

This study tested two interventions-an activities of daily living and a psychosocial activity intervention-and a combination of the two to determine their efficacy in reducing disruptive behaviors and improving affect in nursing home residents with dementia.

METHODS

The study had three treatment groups (activities of daily living, psychosocial activity, and a combination) and two control groups (placebo and no intervention). Nursing assistants hired specifically for this study enacted the interventions under the direction of a master's prepared gerontological clinical nurse specialist. Nursing assistants employed at the nursing homes recorded the occurrence of disruptive behaviors. Raters analyzed videotapes filmed during the study to determine the interventions' influence on affect.

RESULTS

Findings indicated significantly more positive affect but not reduced disruptive behaviors in treatment groups compared to control groups.

CONCLUSIONS

The treatments did not specifically address the factors that may have been triggering disruptive behaviors. Interventions much more precisely designed than those employed in this study require development to quell disruptive behaviors. Nontargeted interventions might increase positive affect. Treatments that produce even a brief improvement in affect indicate improved quality of mental health as mandated by federal law.

AD-venture program: therapeutic biking for the treatment of depression in long-term care residents with dementia

This project tested an innovative intervention in a controlled clinical investigation of a nonpharmacological treatment of depression in long-term care residents with dementia. This treatment utilized a wheelchair bicycle in a recreation therapy protocol, which combined small group activity therapy and one-to-one bike rides with a staff member. Depression levels were significantly reduced in the two-week portion of the study with levels maintained in the 10-week maintenance period. Improvements were also found in sleep and levels of activity engagement.

Easy rider wheelchair biking. A nursing-recreation therapy clinical trial for the treatment of depression

Depression is a common condition among long-term care residents with limited treatment options available. There are few nonpharmacological interventions available to this population. This study examined the use of a prescribed, therapeutic recreation-nursing intervention, wheelchair biking, for treatment of symptoms of depression in older adults in a long-term care setting. A classical experimental design was used and was guided by the Roy Adaptation Model. Forty residents were pretested for depression and randomly assigned to two groups. A 2-week trial of biking therapy was provided to the treatment group. All participants were posttested. Findings indicated there was a statistically significant improvement in depression scores for the treatment group and no significant change for the control group. This study contributes to the body of knowledge of nursing regarding options for the treatment of depression in older adults, and is an encouraging indicator that psychosocial interventions may be effective in reducing depression.

A glider swing intervention for people with dementia

The soothing, repetitive movement of rocking and swinging is well known to anyone who has enjoyed a porch swing or rocking chair. Positive effects of rocking have been reported. However, investigations on its effect in people with dementia are limited. The purposes of this quasi-experimental, repeated-measures design study were to measure the effects of a glider swing on emotions, relaxation, and aggressive behaviors in a group of nursing home residents with dementia (n = 30). Data were obtained during a 5-day baseline phase, a 10-day intervention phase, and a 5-day posttreatment phase. Subjects were placed on the glider for 20 minutes each day during the intervention phase. The results of the study indicate that the glider intervention significantly improved emotions and relaxation. The most noted changes were found after 10 minutes of swinging. However, no differences were found in aggressive behaviors.

Challenges of implementing intervention research in persons with dementia: example of a glider swing intervention

Intervention studies for persons with dementia present many challenges. This article describes challenges encountered in conducting a glider swing intervention study for persons with dementia and the strategies used to manage the problems encountered. The overall purpose of a quasi-experimental study was to explore the effects of a glider swing intervention on emotions, relaxation, and aggressive behaviors in nursing home residents with dementia. Suggestions for investigators conducting intervention studies for persons with dementia are provided.
