Abstract:
Objective:To explore vibration, position and motion proprioception of the ankle joints after a stroke.Methods:Twenty-eight stroke survivors with impaired ankle proprioception were divided into a right-side stroke group ( n=18) and a left-side stroke group ( n=8). Twenty-two healthy volunteers constituted a control group. Vibration perception thresholds, passive and active joint angle resetting, and motion minimum thresholds were quantified among the stroke survivors on both the healthy and the affected side. With the controls the dominant and non-dominant sides were used. The differences in proprioception between the healthy volunteers and the stroke patients, between the affected side and the healthy side of the stroke patients, and between left- and right-side stroke patients were analyzed and compared. Results:Among the stroke survivors the vibration perception threshold on the affected side averaged (28.91±22.53)μm. The absolute difference in the perception of passive positioning was (5.49±5.39)° for 15° of plantar flexion and (4.48±3.89)° for 5° of dorsal extension. In active positioning plantar flexion was (5.23±4.34)° and for 30° of plantar flexion it was (3.26±1.73)°. The 5° dorsal extension error was (4.97±3.48)°. The motion perception thresholds between 20° of plantar flexion, 10° of plantar flexion and the neutral position were significantly higher, on average, than among the control group. The stroke group also had significantly higher motion perception thresholds than the control group.Conclusion:The vibration, position, and motion sense of the ankle joint on a stroke survivor′s affected side tend to be impaired, with the impairment of vibration and motion sensing tend to be more substantial. After stroke, there is also mild impairment of vibration, position and motion sensing in the healthy ankle joint. The impairment of proprioception caused by right cerebral hemisphere injury may be more serious than that caused by injury on the left.
