The purpose of this study was to assess the effectiveness of myofascial release(MFR) technique and Taping therapy on the pain level in whiplash injury patients. Pain level were assessed prior treatment, after first treatment, after second treatment, after third treatment, after fourth treatment, and after fifth treatment. All 6 times were calculated pain level. To find out the effectiveness of MFR and Taping therapy, we were divide two groups. The one group was consisted of 25 patients that were treated with H/P, electrical therapy and MFR, and the other group was consisted of 25 patients that were treated with H/P, electrical therapy, and Taping therapy. The results were as follow: 1. There were statistical significance on the pain level in MFR group during all treatment periods(p<0.05). 2. There were statistical significance on the pain level in Taping group all during treatment periods(p<0.05). 3. Taping group had more statistical significance than MFR group on the pain level during all treatment periods(p<0.05). Consequently, this study suggest that Taping therapy has a very effectiveness to the whiplash injury patients.
