The influence of age and exercise on the mobility of hand joints: 3. thumb joints.

Following our previous study about mobility of the three-phalangeal fingers we have measured flexion in the interphalangeal (IPP) and metacarpophalangeal (MPP) thumb joints as well as thumb opposition (hyperadduction) in university students (52 males and 49 females), seniors (30 males and 30 females) and pianists (21 males and 31 females). In the student control group we did not find difference between males and females or right and left hand, unlike in the previous study of three-phalangeal fingers. The MPP has greater flexion variability than the IPP joint. We have recorded greater limitation in all measured movements in seniors, in the thumb opposition significantly greater in males than in females. Pianists, on the other hand, always show greater thumb opposition, while greater flexion was significant only in the MPP joint in males. We did not record a difference between right and left hand in seniors or pianists.

The effect of age and exercise on wrist mobility.

Wrist mobility was evaluated in university students (52 males and 49 females), seniors (30 males and 30 females) and pianists (21 males and 31 females). We consider the student group as a control with normal mobility. In students we did not notice differences between the right and left wrist motion; however, flexion, radial duction, and range of dorsovolar as well as radioulnar movements were greater in females compared to males. In comparison to students, seniors show limitation of all types of excursions, which is smaller in females than in males (in ulnar duction of females it is insignificant). Differences in mobility between right and left wrist in seniors were not found, while better mobility in females applies to all excursions except flexion. Pianists, compared to students, have greater ulnar duction, and in the case of males also flexion. Hyperextension and radial duction are the same as in the control group. No differences between sides or sexes are apparent. Compared to the control group, the range of dorsovolar and in particular radioulnar motion is greater only in pianist males, while in females the difference is minimal.

The influence of age and exercise on the mobility of hand joints: 1: Metacarpophalangeal joints of the three-phalangeal fingers.

Mobility of metacarpophalangeal joints (MP) of the three-phalangeal fingers was measured in university students (52 males and 49 females), senior citizens (30 males and 30 females), and pianists (21 males and 31 females). We consider the student data file to be a control group with hand mobility unchanged by external influence. Extension, flexion, and total abduction in this group are greater in the left than the right hand. Only extensions were greater in females compared to males. In seniors, all types of studied movements are, with the exception of total abduction in females, lesser that in the control group. The difference is more apparent in males than in females. Intersexual difference showing better MP joint mobility in females than males is thus greater in seniors than in students; however, greater mobility of MP joints in left compared to right hand is less noticeable. Compared to students, pianists show greater finger abduction, and--less markedly--also passive and active extensions, while we did not notice difference in finger flexion. Intersexual difference in MP joint mobility in pianists were not recorded, and better mobility on the left hand compared to the right hand was evident only in dorso-palmar movements in males (the exception was total finger abduction, which is greater for the left hand in males as well as in females). In the three studied series we did not register differences in interfinger abduction between the left and right hand or between sexes. Active dorso-palmar MP joint range of motion is greatest in the little finger and smallest in the index finger, smallest in seniors and greatest in pianists. In all three groups, the range is greater in the left than the right hand and in females compared to males.

The influence of age and exercise on the mobility of hand joints: 2: Interphalangeal joints of the three phalangeal fingers.

This report is a continuation of the study about mobility of the metacarpophalangeal (MP) joints of the three-phalangeal fingers. We measured flexion of proximal (PIP) and distal (DIP) interphalangeal joints in university students (52 males and 49 females), senior citizens (30 males and 30 females), and pianists (21 males and 31 females). Students were considered as a control group characterized by normal mobility of hand joints. In all three groups, the smallest flexion in the PIP joints is in the little finger, in the DIP joints in the index and ring fingers. In the control group the flexion in the PIP joints is greater in females compared to males, in the DIP joints it is greater on the left side compared to the right. With the exception of DIP joints in females, the situation is also similar in seniors. In pianists, however, the gender and lateral differences are less pronounced, due to exercise. Seniors of both genders show significant limitation of flexion in all PIP as well as DIP joints, as compared to students, while pianists have the same range of flexion compared to students, which also corresponds to the situation in MP joints. The previous study, however, showed that pianists have a greater ability to abduct and hyperextend fingers.
