Objective:
To provide distribution-based estimates of the minimal clinical important difference (MCID) after slow release fampridine treatment on cognition and functional capacity in people with MS (PwMS).
Method:
MCID values were determined after SR-Fampridine treatment in 105 PwMS. Testing included the Timed 25 Foot Walk (T25FW), the Symbol Digit Modalities Test (SDMT), the Six Spot Step Test (SSST), the 9-Hole-Peg-Test (9-HPT), and the 5-Time-Sit-To-Stand test (5-STS).
Results:
MCID values: T25FW 17.8% (9.1-17.8), SDMT 17.1% (9.2-17.1), SSST 16.7% (8.5-16.7), 9-HPT 15.3% (0-15.3), and 5-STS 34.6% (16.9-34.6).
Conclusion:
This study presents distribution-based estimates of MCID values for the SSST, the 9-HPT, and the 5-STS and confirms MCID estimates for the T25FW and the SDMT.
