Relationship between Trunk Performance and the Stair Ascending and Descending in Post Stroke Subjects
Keywords:Stroke, trunk impairments, trunk control, anticipatory postural adjustments, trunk scales, stair ascend and descend test.
Purpose and Objective:- Trunk being the central keypoint of the body, good trunk stability is essential
for reaching and grasping and proximal trunk control is a prerequisite for distal lower limb movement
control in functional activities like walking and stair climbing. There are several clinical tools to measure
trunk performance such as The sitting balance item of the Motor assessment scale, The trunk control
test, leg and trunk scale of the Rivermead Motor Assessment Scale. The Trunk Impairment Scale (TIS)
a new tool to measure motor impairment of trunk after stroke was developed in 2004 by G Verheyden
et al. Studies were conducted to correlate the TIS with Tinette, TUG test, 10 min walk test. However
studies were not conducted to show the relationship between the trunk impairment and stair climbing in
stroke subject. Design:- Correlational study Settings:-HOSMAT Hospital, BangaloreSubjects:-A total
of 32 stroke subjects with a mean (SD) age of 53.90 ± 13.07 yrs. 21 males and 11 females participated.
Method:-All the 32 subjects were administered with TIS and then followed by stair ascend and
descend test. Outcome measures:- TIS, Stair ascend and descend test.Results:-The median scores of
static, dynamic sitting balance and coordination ( 5, 6, 1) respectively. Mean score of stair ascend -
18.87±11.05 and for stair descend - 20.60±12.43.There was a moderate negative correlation between
TIS and stair ascend with rs
= -0.54 (P=0.001), moderate negative correlation between TIS and stair
descend with rs
=-0.63(P=0.001) and also moderate negative correlation between TIS and stair ascend +
= 0.58(P=0.001).Conclusion:-The Trunk impairment scale shows moderate correlation with
the stair ascend and descend test, which suggests that a person scoring less on the Trunk Impairment
Scale (TIS ) takes more time to ascend and descend the stairs.
