The effects of trunk repositioning errors on trunk and extremity functions in stroke.

AIM

The aim of this study was to analyze the TRE in three directions including forward flexion, lateral flexion to the hemiparetic side, and rotation to the hemiparetic side in patients with stroke and to compare the errors with age- and sex-matched healthy subjects. In addition, it was investigated which functional outcomes were explanatory for TRE in patients with stroke.

METHODS

Forty-one patients with subacute/chronic stroke (age 59 ± 14.5 years) and 41 healthy subjects (age 57 ± 12.8 years) were included in the study. Demographic and clinical data were collected. TREs were measured using an inclinometer. The Trunk Impairment Scale (TIS), Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT), Timed Up and Go Test, and 10-m walk test (10MWT) were also used to assess trunk control, motor impairment, upper extremity function, and lower extremity function, respectively, in patients with stroke.

RESULTS

TRE scores in three directions were higher in patients with stroke than in healthy subjects ( < 0.001). TREs in three directions were significantly strongly correlated with all functional outcomes (ρ > 0.60,  < 0.001). Multiple regression analysis determined 10MWT, WMFT-Performance, TIS, and FMA-Upper Extremity as explanatory factors for TRE.

CONCLUSION

The model presented in this study could help clinicians and researchers to predict the TRE in patients with stroke. Gait speed, upper extremity motor ability, upper extremity motor impairment, and trunk control should be considered for TRE after a stroke.
