Abstract

BACKGROUND&OBJECTIVE:This studywas executed to find out correlation between postural alignment in sitting measured through photogrammetry and postural control in sitting following stroke. METHODS: A cross-sectional study with convenient sampling consisting of 45 subjects with acute and sub-acute stroke. Postural alignment in sittingwas measured through photogrammetry and relevant angles were obtained through softwareMBRuler (version 5.0). Seated postural control was measured through Function in Sitting Test (FIST). Correlation was obtained using Spearman’s Rank Correlation co-efficient in SPSS software (version 17.0). RESULTS: Moderate positive correlation (r = 0.385; p < 0.01) was found between angle of lordosis and angle between acromion, lateral epicondyle and point between radius and ulna. Strong negative correlation (r =−0.435; p < 0.01)was found between craniovertebral angle and kyphosis. FIST showed moderate positive correlation (r = 0.3446; p < 0.05) with cranio-vertebral angle and strong positive correlation (r = 0.4336; p < 0.01) with Brunnstrom’s stage of recovery in upper extremity. CONCLUSION: Degree of forward head posture in sitting correlates directly with seated postural control and inversely with degree of kyphosis in sitting post-stroke. Postural control in sitting post-stroke is directly related with Brunnstrom’s stage of recovery in affected upper extremity in sitting.
