Impact of the Chin-Down Posture on Temporal Measures of Patients With Dysphagia: A Pilot Study

The effectiveness of chin-down manoeuvre in patients with dysphagia: A systematic review and meta-analysis

AIM

The chin-down posture is a widely used compensatory manoeuvre for patients with dysphagia. The aim of this study was designed to systematically measure the effectiveness of chin-down manoeuvre application.

METHODOLOGY

We retrieved the PubMed, Web of Science, Embase, Cochrane Library, EBSCO, Medline, CNKI, WANFANG, VIP and SinoMed databases from inception to 30 August 2022. Raters independently screened literature according to inclusion and exclusion criteria. The quality of the included literature was evaluated, and data were extracted. The software Review Manager software 5.3 was used for statistical analysis.

RESULTS

Fourteen studies with a total of 571 patients were included in this meta-analysis. The meta-analysis indicated that chin-down manoeuvre could significantly reduce the risk of aspiration (MD = -1.35, 95% CI [-2.25, -0.44], Z = 2.92, p < .01), decrease the chin angle (MD = -12.20, 95% CI [-14.61, -9.79], Z = 9.91, p < .001), shorten oral transit time (MD = -0.81, 95% CI [-1.20, -0.43], Z = 4.17, p < .001), reduce the maximum swallowing pressure at upper oesophageal sphincter (MD = -82.07, 95% CI [-112.77, -51.37], Z = 5.24, p < .001) and decrease pharyngeal residue.

CONCLUSIONS

Existing evidence indicated that chin-down manoeuvre could reduce the risk of aspiration and pharyngeal residue, decrease the maximum swallowing pressure at UES. More large-sample, high-quality clinical trials are still needed in the future to further ascertain the results of this research.

Qualifications, professional roles and service practices of nurses, occupational therapists and speech-language pathologists in the management of adults with oropharyngeal dysphagia: a Nordic survey

PURPOSE

To identify the qualifications, professional roles and service practices of nurses, occupational therapists (OTs) and speech-language pathologists (SLPs) in the management of adults with oropharyngeal dysphagia (OD) in the Nordic countries.

METHODS

A web-based survey was developed that consisted of 50 questions on respondent demographics, education, experience, roles and service practices provided for adults with OD. The survey was distributed to practicing nurses, OTs, and SLPs in five Nordic countries via professional associations, social media, online networks and snowballing.

RESULTS

Data from 396 nurses, OTs and SLPs whom provided services for adults with OD revealed that the majority of respondents worked in acute care and inpatient rehabilitation facilities. Most respondents had minimal undergraduate education and practical clinical training in OD. Notable variances in roles and service practices in OD between professions and countries were found. OTs were the primary service provider for OD management in Denmark, while SLPs had this role in the other Nordic countries. Nurses were mainly involved in screening and some compensatory treatments in most Nordic countries. Limited use of evidence-based screening, non-instrumental or instrumental clinical assessments and rehabilitative therapeutic methods was evident.

CONCLUSIONS

Study results highlight challenges in education and training of professionals responsible for the management of adults with OD in the Nordic countries. Increased use of evidence-based assessment and exercise-based treatments to improve swallowing are warranted. Adherence to European and international clinical practice guidelines for the management of adults with OD is recommended.

Association between swallowing function, malnutrition and frailty in community dwelling older people

BACKGROUND & AIMS

Swallowing function decreases with age and impacts nutritional state and frailty. The aim of the study was to test the relationship between swallowing function, dysphagia, frailty, malnutrition and depression in community dwelling older participants.

METHODS

Community dwelling older participants (n = 180), were enrolled (74 men aged 75.9 ± 7.8, 65-91 years, and 107 women aged 75.9 ± 8.0, 65-95 years). Swallowing function was assessed by the Test of Mastication and Swallowing Solids (TOMASS) and the Timed Water Swallow Test (TWST). Dysphagia was identified using Hebrew 10-Item Eating Assessment Tool (H-EAT-10). Frailty was assessed by grip strength and the FRAIL Questionnaire. The Mini Nutritional Assessment - Short Form (MNA-SF) was used to identify nutritional status. Depression was screened with the Geriatric Depression Scale - Short Form (GDS-SF).

RESULTS

18.3% of the participants had a score of 3 or above in H-EAT-10, indicating suspected dysphagia. 17.8% of the participants were malnourished or at risk of malnutrition, and 48.3% were defined as frail or pre-frail. The odds of being malnourished/at risk of malnutrition were 3 times greater in those with suspected dysphagia. The odds of being frail/pre-frail were also 3 times greater in those with suspected dysphagia. Moreover, suspected dysphagia and frail/pre-frail health status coincided in 69.7% of participants. Participants that were malnourished/at risk of malnutrition required more masticatory cycles (p < .05) and more time (p < .05) to eat a cracker and drink 150 mL of water (p < .05), and had reduced swallowing capacity (volume/sec) in the TWST (p < .05) than those who were at normal nutritional statues. Similar results were found for frail/pre-frail participants versus robust health status. A decrease in grip strength was associated with increased (worse) frailty score, decreased nutritional score, decreased chewing function in TOMASS and decreased water drinking function in TWST (p < .05). MNA-SF score, age, GDS-SF score and EAT-10 were the best predictors of FRAIL score.

CONCLUSION

A simple multi-dimensional screen should be employed by trained allied health professionals, nurses and their assistants to improve early identification and early referral to relevant health providers in order to provide preventive intervention for dysphagia, nutrition, frailty and depression.
