Abstract
Objective
The main objective of this pilot study was to explore the effect of chiropractic high-velocity,
low-amplitude (HVLA) manipulation on vertical jump height in young female athletes
with talocrural joint dysfunction.
Methods
This was a randomized assessor-blind clinical pilot trial. Twenty-two female handball
players with talocrural joint dysfunction were randomized to receive either HVLA manipulation
(n = 11) or sham treatment (n = 11) once a week during a 3-week period. The main outcome
was change in vertical jump height from baseline to follow-up within and between groups
after 3 weeks.
Results
Nineteen athletes completed the study. After 3 weeks, the group receiving HVLA manipulation
(n = 11) had a statistically significant mean (SD) improvement in vertical jump height
of 1.07 (1.23) cm (P = .017). The sham treatment group (n = 8) improved their vertical jump height by
0.59 (2.03) cm (P = .436). The between groups' change was 0.47 cm (95% confidence interval, −1.31 to 2.26; P = .571) in favor of the group receiving HVLA manipulation. Blinding and sham procedures
were feasible, and there were no reported adverse events.
Conclusion
The results of this pilot study show that a larger-scale study is feasible. Preliminary
results suggest that chiropractic HVLA manipulation may increase vertical jump height
in young female athletes with talocrural joint dysfunction. However, the clinical
result in favor of HVLA manipulation compared with sham treatment needs statistical
confirmation in a larger randomized clinical trial.
