Do Heberden and Bouchard nodes affect finger dexterity in elderly?

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. The nine-hole peg test was used for dexterity measurement in 200 elderly with HN and/or BN. Mean age was 68.6 +/- 5.39 years. Average performance of each hand was compared between elderly with or without nodes. HN and BN were found in 75 right hands (37.5%) and 73 left hands (36.5%). Nodes were found in females more often than males (p < 0.001). Average right hand dexterity in elderly with and without nodes was 21.6 +/- 3.16 and 21.4 +/- 3.16 s. Average left hand dexterity in elderly with and without nodes was 23.3 +/- 3.13 and 23.3 +/- 3.67 s. There was no significant difference between elderly with or without nodes (p >/= 0.05). In conclusion, 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.
