Abstract

Background contextThere has been no research into the short term effects of self-cavitation of the metacarpal phalangeal joints (MCP) on grip strength. PurposeTo identify the effects (if any) of MCP self-cavitation on grip strength. Study design/settingUniversity based randomised controlled trial. Patient sample61 asymptomatic participants. Outcome measuresOutcome was evaluated with a grip strength dynamometer before and after intervention. Methods61 asymptomatic subjects were randomised into each of the three groups; control, high velocity low amplitude cavitation (HVLAT) or placebo (SHAM). Participants were asked to perform 3 grip strength readings on each hand, before and after the intervention. Grip strength readings were averaged, the difference between pre intervention and post intervention averages was then taken, and the average for each intervention evaluated by two way ANOVA for significant difference. ResultsFor the left hand, there was a significant decrease in average grip strength between interventions; HVT and Control groups (M=2.502,t=2.357, p=0.044) and HVT and Sham groups M=3.935, t= 3.707, p= 0.002) . Hours playing sport showed a statistically significant post intervention decrease in grip strength (p=0.045), compared to those who did not play sport. No significant difference was found between control and sham group (M= 1.43, t=1.36, P=0.177). There was no statistical difference between hand dominance (P= 0.303), height (P= 0.840), weight (P= 0.982) and number of knuckles cavitated (P=0.45). For the right hand there was no statistical significance for any of the values affecting grip strength, regardless of intervention (P= 0.109) , gender (P= 0.20), hand dominance (P= 0.629), height (P=0.856), weight (P= 0.711), sporting hours (P = 0.451) and number of knuckles cavitated (P=0.81). ConclusionMCP cavitation was found to have an immediate effect of reducing the grip strength of the subject’s left hand. Therefore further research into effects of cavitation on grip strength, and its interaction with hand dominance, sham intervention, sporting hours and autonomic dysregulation on grip strength are recommended with a larger sample size.
