Abstract:
Objective:To evaluate the influence of manual digitorum sensory stimulation (MDSS) of hemiplegic fingers in median nerve F-wave in stroke patients.Methods:Thirty patients with hemiplegia after stroke, admitted to Department of Rehabilitation Medicine, Second Affiliated Hospital of Anhui Medical University from June 2019 to October 2022 were selected; all patients had thumb flexor modified Ashworth scale (MAS) grading≥1. Hemiplegic MDSS was given; bilateral median nerve F-wave before MDSS and median nerve F-wave at the hemiplegic side immediately after MDSS were recorded.Results:Compared with that at the healthy side before MDSS, amplitude of median nerve F-wave at the hemiplegic side was significantly increased ( P<0.05). Compared with that before MDSS, amplitude of F-wave at the hemiplegic side after MDSS in patients with thumb flexor MAS grading≤2 were significantly decreased ( P<0.05), while that in patients with thumb flexor MAS grading≥3 was significantly increased ( P<0.05). Conclusion:Amplitudes of median nerve F-wave at the hemiplegic side in patients with different thumb flexor MAS grading show that MDSS can not only inhibit the excitability of tonic motor unit related to muscle spasm, but also enhance the excitability of kinetic-motor unit mainly related to explosive power in severe muscle spasm.
