Minimal Detectable Changes of the Berg Balance Scale, Fugl-Meyer Assessment Scale, Timed Up & Go Test, Gait Speeds, and 2-Minute Walk Test in Individuals With Chronic Stroke With Different Degrees of Ankle Plantarflexor Tone

Hiengkaew V et al. – The Berg Balance Scale (BBS), Fugl–Meyer Assessment (FMA–LE), Timed “Up & Go” test (TUG), comfortable gait speed (CGS), fast gait speed (FGS), and 2–minute walk test (2MWT) are reliable measures to detect postural balance and lower limb movements in individuals with chronic stroke who have differences in ankle plantarflexor tone. The absolute and relative MDC95 of each measure are dissimilar in those with differences in ankle plantarflexor tone. The relative MDC95 seems more useful than the absolute MDC95 because the relative value can be used for a single individual.Methods
- Data were collected on 2 occasions, about 6 days apart.
- Outpatientphysicaltherapy clinics.
- Volunteers (N=61) with chronic stroke who were able to walk and had differences in ankle plantarflexor tone: no increase in ankle plantarflexor tone (n=12), a slight increase in ankle plantarflexor tone (n=32), and a marked increase in ankle plantarflexor tone (n=17).
- Reliability and absolute and relative MDC95 of the Berg Balance Scale (BBS), the lower limb subscale of Fugl-Meyer Assessment (FMA-LE), the Timed “Up & Go” test (TUG), the comfortable gait speed (CGS), the fast gait speed (FGS), and the 2-minute walk test (2MWT).
- Excellent reliability of the BBS, FMA-LE, TUG, CGS, FGS, and 2MWT for all the participants combined and for the subgroups was shown.
- All the participants combined showed the absolute and relative MDC95 in the BBS of 5 points and 10%, FMA-LE of 4 points and 16%, TUG of 8 seconds and 28%, CGS of 0.2m/s and 34%, FGS of 0.1m/s and 21%, and 2MWT of 13m and 23%.
- The absolute and relative MDC95 of the subgroups were varied based on ankle plantarflexor tone.
