Abstract [en]

Introduction: Muscle strength, endurance and proprioceptive input are important for stability of the wrist and to perform powerful and precise movements of the hand. Common exercises for handgrip involve strength and coordination training with stable or unstable equipment to improve grip strength, proprioception and hand functioning, but little is known about different effects of these methods. Aim: The aim of this study was to compare the effects on grip force and force sense by training with either unstable (Powerball®) or stable (power grip) exercise tool. Method: Twenty healthy participants were recruited and randomized into two intervention groups; one training dominant hand with Powerball® and one with power grip. Intervention included three training sessions per week during six weeks. Assessments were performed immediately before and after the intervention period and included maximum grip strength and force sense tests of both dominant and non-dominant hand, measured with a grip dynamometer. Due to drop out 9 participants from Powerball® group and 8 from power grip group completed the study. Results: Grip strength increased in both hands and in both groups but did not show any significant effects. Absolute error of the force sense increased significantly in dominant hand in the Powerball® group, but there were no significant group differences. Conclusion: Grip strength training was not improved significantly which was possibly due to low power (few participants). The fact that force sense was deteriorated immediately after Powerball® training was unexpected and need further investigation. Overall there were no significant differences between groups in this pilot study.
