  • Title: Proprioception deficits in chronic stroke-Upper extremity function and daily living.
    Author: Rand D.
    Journal: PLoS One; 2018; 13(3):e0195043. PubMed ID: 29601594.
    Abstract:
    BACKGROUND: Proprioception deficits are common post-stroke and predict poor functional outcome. It is unknown if the presence of proprioception deficits is negatively associated with the motor and functional ability of the affected upper extremity and daily living at the chronic stage post-stroke. AIMS: 1) To describe proprioception deficits of individuals with chronic stroke, 2) to correlate the severity of proprioception deficits with the motor and functional ability of the upper extremity, and 3) to compare independence in basic and instrumental activities in daily living (BADL, IADL), upper extremity motor and functional abilities between individuals with and without proprioception deficits. METHODS: 102 adults aged 29-85 years with chronic stroke participated in this cross sectional study. The upper extremity was assessed for proprioception (Thumb localization Test), motor [Fugl-Meyer Motor Assessment (FMA)] and functional ability [Action Research Arm Test (ARAT), Box and Block Test (BBT)], grip strength and daily use [Motor Activity Log (MAL)]. Independence in BADL and IADL was also assessed. RESULTS: 71 participants had intact proprioception, 31 participants had mild-moderate proprioception deficits. Negative significant (p<.001) correlations were found between the severity of proprioception deficits to the motor ability (FMA) (r = -.41), functional ability (ARAT) (r = -.48), dexterity (BBT) (r = -.43), grip strength (r = -.41) and daily-use (MAL amount and quality) (r = -.55 and r = -.54, respectively) of the affected upper extremity. Significant between-group differences were found for BADL, IADL and upper extremity measures. CONCLUSION: Proprioception deficits of individuals with chronic stroke are negatively associated with upper extremity motor and functional abilities and independence in daily living. Therefore, proprioception should be assessed at the chronic stage post-stroke.
