Do Heberden and Bouchard nodes affect finger dexterity in elderly?
Rheumatology International, 10/12/09

Kitisomprayoonkul W et al. – Elderly often have Heberden nodes (HN) and Bouchard nodes (BN) that may affect finger dexterity. The aim of this cross-sectional study was to assess an effect of HN and BN on finger dexterity of the elderly. . It was found that HN and BN in elderly hands do not affect finger dexterity. Therapist may use the same training program to prevent deterioration of finger dexterity in elderly with or without nodes.

Methods

9-hole peg test used for dexterity measurement
200 elderly with HN and/or BN
Mean age 68.6 ± 5.39 years
Average performance of each hand compared between elderly with or without nodes

Results

HN and BN found in 75 right hands and 73 left hands
Nodes found in females more often than males
Average right hand dexterity in elderly with and without nodes 21.6 ± 3.16 and 21.4 ± 3.16 s
Average left hand dexterity in elderly with and without nodes 23.3 ± 3.13 and 23.3 ± 3.67 s
No significant difference between elderly with or without nodes
