dietetic practice

Jane McClinchyPrincipal Lecturer

University of Hertfordshire

Content

• The equipment and methods used to assess hand grip strength

• The research relating to the use of hand grip strength and the

assessment of nutritional status

• Relate this to dietetic practice

Introduction

• Handgrip strength is useful as a test of skeletal function

• The test was developed by hand therapists

Indicator of concurrent and future status

The use of hand grip strength as a predictor of nutritional status in hospital patients

Recommended use in dietetics?

• For diagnosing ‘severe’ malnutrition (White et al 2012)

• Screening for malnutrition in patients with renal disease (Wright and Jones, 2010)

• Nutritional status and disease severity in adults with cystic fibrosis (Mead et al., 2014) (Mead et al., 2014)

• Prognostic predictor in: • Haemodialysis patients (Isoyama et al., 2012)

• Alcoholic liver disease (Plauth et al., 2006)

• Liver disease (Alvares-da-Silva and Reverbel da Silveira., 2005)

• Potential to show impact of intervention (Gandy, 2014)

Application to dietetics

• Where changes in fluid status make BMI unreliable

• For auditing the outcome of our clinics

• Would like to use it more frequently

• Plan to review the values being used

Specialist areas

• Liver patients

• Haemodialysis patients

• Children and adults with cystic fibrosis

• GI Clinic

• Malnutrition in the elderly

Measurement top tips

• Calibrate the equipment

• Set to kg

• Use the same method

• Standing or sitting does not seem to matter (see Dodds et al 2014)

• Dominant vs non dominant –studies vary • Dominant vs non dominant –studies vary

• Aiming to get the maximal grip strength

• Give patients time to get used to the equipment

• Compare to normative values for your population

Grip strength varies with different population groups

Standards in use in practice

Gandy (2014) Page 54

Todorovic and Micklewright(2011) page 2.21

Technique: Squeeze as hard as possible on three occasions using the non-dominant arm. The highest reading should be taken.

Dodds et al 2014

Clinical application

• Klidjian et al 1980 propose 85% of normative value by age which is equivalent to 1 SD

• Having grip strength comparable to younger adults is more desirable than having grip strength comparable to other older adults whose strength has also declined with age’ (Bohannon 2015)

• Dodds et al 2014 propose -2.5 SD from the maximal value to define a • Dodds et al 2014 propose -2.5 SD from the maximal value to define a weak grip

Conclusion

• Standard method

• Normative values for your community

• Use 1 SD to define weak grip

• Simple ‘bedside’ / clinical parameter

• Useful in dietetics as a tool to monitor nutritional status• Useful in dietetics as a tool to monitor nutritional status

• Alongside other methods
