Although information on the range of motion (ROM) required to perform activities is
important when setting ROM goals to enable patients to engage in them, there are few studies reporting
the required ROM of fingers.
Purpose of the study: To analyze the range of joint motion required of the finger MCP joint to perform
activities and to compare the maximum flexion and maximum extension angle required of the finger
MCP joints in the individual fingers.
Methods: We used an electrogoniometer to measure the ROM of four finger MCP joints in the dominant
hand in healthy adults (n?20) performing 19 activities. FingerMCP joint angles were analyzed throughout
each of the 19 tasks.
Results: The mean ROMof fingerMCP joints of the index, middle, ring, and little fingers required to perform
all 19 activities ranged from 10 to 60, 10 to 75, 10 to 80, and 10 to 85, respectively. The mean
maximum flexion angle of the finger MCP joints gradually increased as the finger MCP joints were
compared moving from the radial to the ulnar side.
Conclusion: The data obtained in this study on MCP joint motions that are required to perform activities
may be beneficial in setting ROM goals for patients with finger MCP joint impairment.
Level of evidence: NA.
