Table 3.

Prevalence and distribution of MAS and MMT scores for the muscles around the hip, knee, and ankle joint in the selected limbs (N = 446) from the patient population.

MAS score [N (%)]
0 1 1+ 2 3 4
Hip 93 (20.9) 123 (27.6) 130 (29.1) 98 (22.0) 2 (0.4) 0 (0.0)
Knee 22 (4.9) 118 (26.5) 153 (34.3) 142 (31.8) 11 (2.5) 0 (0.0)
Ankle 9 (2.0) 46 (10.3) 196 (43.9) 164 (36.8) 26 (5.8) 5 (1.1)
MMT score [N (%)]
0 1 2 3 4 5
Hip 0 (0.0) 7 (1.6) 33 (7.4) 231 (51.8) 162 (36.3) 13 (2.9)
Knee 0 (0.0) 0 (0.0) 14 (3.1) 191 (42.8) 221 (49.6) 20 (4.5)
Ankle 5 (1.1) 68 (15.2) 85 (19.1) 189 (42.4) 83 (18.6) 16 (3.6)

The muscles around the hip, knee, and ankle joint are summed following the approach described in section Clinical examination of weakness and spasticity. If less than 50 limbs were classified in a particular category of the MMT or MAS scale, the expected frequencies in the cross-tables were generally too low to allow a valid interpretation of χ2, especially for analyses in combination with joints that have a high number of patterns [e.g., knee during stance (n = 7)]. Therefore, darker shaded categories were merged at the level of each joint, all indicating a lower level of spasticity or a higher level of muscle weakness. Lightly shaded areas were merged at the level of each joint, indicating a higher level of spasticity and a lower level of muscle weakness.
