Calculate finger range of motion with TAM and Strickland
Enter active flexion and extension deficit values measured with a goniometer; see total active motion, the ratio to the uninjured side and the Strickland score.
Affected finger
MCP
PIP
DIP
Uninjured side (optional)
MCP
PIP
DIP
Result
Enter at least the PIP and DIP values of the affected finger.
Strickland JW, Glogovac SV. J Hand Surg Am. 1980;5(6):537–543. Grading: 85–100% excellent, 70–84% good, 50–69% fair, <50% poor.
Measurement consistency
Goniometer readings should be taken in the same position and, if possible, by the same person. Treatment decisions belong to the hand surgeon and hand therapist.

Run this measurement automatically from a scan in your clinic
In a 30-minute demo we'll show the same calculation on a 3D scan, with your own case. Your result is added to the form automatically.

Frequently asked questions
How is TAM (total active motion) calculated?
TAM = (sum of MCP + PIP + DIP active flexion) − (sum of the extension deficits of the three joints). If the same calculation is made for the uninjured finger, the injured finger's ratio to the uninjured side is obtained as a percentage.
What is the Strickland score?
It is the measure defined by Strickland and Glogovac (J Hand Surg Am, 1980) for outcome after flexor tendon repair: (PIP + DIP active flexion − PIP and DIP extension deficit) ÷ 175 × 100. Results of 85–100% are excellent, 70–84% good, 50–69% fair and below 50% poor.
How do I enter an extension deficit?
If a joint cannot fully straighten, enter the missing angle as a positive number of degrees (for example 20 if the PIP stays flexed by 20°). Enter 0 for hyperextension.
