Sensori-motor Recovery In Post-stroke Shoulder Subluxation: A Non Invasive Correlation Study

ABSTRACT

Background: Stroke is the most common neurological condition causing long term disabilities in various ways.Post-stroke shoulder subluxation, mainly the Gleno-humeral Subluxation (GHS) of the affected side is oftendetected as a complication. Numerous theories exist to explain the pathomechanics of developing GHS,butstudies regarding its relationship with the sensori-motor recovery of the affected limb is still controversial.Aim of Study To ascertain the correlation between Gleno-humeral subluxation with sensori-motor recovery ofthe affected upper limb following stroke.Method: This correlation study was conducted on 30 patients of both sexes within the age group of 45-65 yearswith post-stroke (duration < 6weeks) Gleno-humeral subluxation( GHS). Screening of GHS was done by palpationand degree of GHS was quantified by High resolution USG by measuring the Acromion - Greater TuberosityDistance difference (AGTDD) between two shoulders. Sensorimotor recovey of the affected limb was assessed byFugl - Meyer Assessment Scale of Upper Extremity (FMA-UE). Data collected at the baseline (visit1), at 6 weeks(visit 2), 12 weeks (visit 3) and at the end of the study i.e 24 weeks (visit 4).Results: Pearson Correlation (r) in all visits (V1 r=-0.926, p=0.000. V2 r=- 0.947, p=0.000. V3 r=- 0.912, p=0.000.V4 r=- 0.924, p=0.000) established a statistically significant negative correlation between degree of shouldersubluxation and sensory-motor recovery.Conclusion: Post-stroke GHS is a significant complication which undoubtedly plays a cardinal negative roleduring sensori-motor recovery of the affected upper limb.KEY WORDS Gleno-humeral subluxation (GHS), Acromion-Greater Tuberosity Distance difference (AGTDD),
