Özet

ObjectiveThis study aims to reveal the effect of low-frequency local vibration applied to the forearm extensor muscles on stroke patients' muscle activation and hand functions.MethodsTwenty-four stroke patients were randomized to the vibration group (n = 12) or control group (n = 12). The vibration was applied at a 30 Hz frequency to the forearm extensor muscles with a local vibration device three days a week after the routine, conventional physical therapy sessions for four weeks. Six vibration sets were applied, including one vibration for one minute and a rest for 2 min. Routine, traditional physical therapy was used for the control group in 60-min sessions for 4 weeks. Patients were assessed for muscle activation with surface electromyography (MVC) and The Wolf Motor Function Test (WMFT), Functional Independent Test (FIM) was applied to all patients before and after treatment.ResultsAs a result of our study, MVC measurement, WMFT and FIM scores of the vibration group showed more improvement than the control group. Measurement results of vibration group; While MVC measurement increased from 10.21 to 13.79, WMFT-Functional Ability score increased from 42 to 50, WMFT-Performance Time duration increased from 68.78 to 61.83, and FIM score increased from 74.5 to 83. and the measurement results of the control group; MVC measurement increased from 12.28 to 12.22, WMFT-Functional Ability score increased from 48.5 to 51, WMFT-Performance Time duration increased from 70.39 to 70.61, and FIM score increased from 72.5 to 80.5.ConclusionIt was concluded that low-frequency local vibration applied to the forearm extensor muscles improve forearm extensor muscle activation and hand motor function.
