The aim of this study was to determine the effect of using the Powerball gyroscope as a treatment device on pain and change in endurance in nonspecific wrist pain.
This study was a within-participants pre- and postintervention study consisting of 40 participants between ages 18 and 35 with an equal male-to-female ratio. The participants used the Powerball gyroscope for 5 minutes per treatment session. Treatment comprised 12 sessions carried out 3 × per week over a 4-week period. Participants completed objective and subjective data before the first, seventh, and 12th sessions. Objective data were recorded using the Jamar dynamometer to measure grip strength. Subjective data were gathered using the Patient-Rated Wrist Evaluation Questionnaire. Participants then used the Powerball gyroscope in the hand with the affected wrist. The Wilcoxon signed rank test and 1-way repeated-measures analysis of variance were used to analyze the changes.
A significant decrease in pain was noted throughout the study, but the most significant changes occurred between the seventh and 12th treatment sessions (P < .01). A significant increase in grip strength was also noted throughout the study, with the greater increase in grip strength occurring during the first 7 treatments (P < .02).
The Powerball gyroscope showed a change in outcome regarding nonspecific wrist pain and grip strength.
本研究旨在确定使用 Powerball 陀螺仪作为治疗设备对非特异性腕痛的疼痛和耐力变化的影响。
这是一项参与者内的干预前后研究，共纳入 40 名年龄在 18 至 35 岁之间、男女比例相等的参与者。参与者使用 Powerball 陀螺仪进行 5 分钟的治疗。治疗包括 12 次治疗，每周 3 次，持续 4 周。参与者在第一次、第七次和第十二次治疗前完成客观和主观数据的记录。客观数据使用 Jamar 握力计测量握力。主观数据通过患者腕部评估问卷收集。参与者随后在受影响手腕的手中使用 Powerball 陀螺仪。使用 Wilcoxon 符号秩检验和单向重复测量方差分析来分析变化。
研究过程中疼痛明显减轻，但在第七和第十二次治疗之间变化最显著（P <.01）。握力也明显增加，在最初的 7 次治疗中增加幅度更大（P <.02）。
Powerball 陀螺仪在非特异性腕痛和握力方面显示出了治疗效果的变化。
