The effect of spasticity, sense and walking aids in falls of people after chronic stroke

Objective. To study the effects of spasticity, sensory impairment, and type of walking aid on falls in community dwellers with chronic stroke. Methods. Functional Independence Measure (FIM) Instrument, Joint Position Sense Evaluation (JPS), the Rivermead motor assessment scale (RMA), Ashworth Scale, Tinetti Assessment Tool were used to assess 100 cases. Results. Fifty-three of the cases were grouped as nonfallers, 36 as one-time fallers and 11 as repeat fallers. These 3 groups were found to be different from each other in respect to FIM, Tinetti test and RMA (p < 0.001). In respect to knee JPS, nonfallers and one-time faller groups were found to be different from repeat fallers (p = 0.001). There is a difference among the groups in respect to Ashworth assessment (p < 0.001), use of walking aid (p = 0.01) and type of walking aid (p = 0.01). Some 43% of the cases use a walking aid (58.1% cane, 41.9% high cane). According to Ordinal logistic regression analysis, it was found that the possibility of fall increased (p < 0.01), as the value of spasticity increased while the possibility of the fall of the individuals with stroke decreased (p < 0.00 – 0.01) as Tinetti, RMA and FIM variables increased. Conclusions. In respect to falls, spasticity is also an indicator for chronic stroke patients, as is motor impairment, functional situation, impairment of balance and walking. Sensory impairment, using a walking aid and the type were found to be ineffective.
