Abstract
Objective
The objective of this study was to perform an investigation evaluating if cervical
spinal manipulative therapy (SMT) can increase grip strength on judo athletes in a
top 10 national-ranked team.
Methods
A single-blinded, prospective, comparative, pilot, randomized, clinical trial was
performed with 18 athletes of both sexes from a judo team currently competing on a
national level. The athletes were randomly assigned to 2 groups: chiropractic SMT
and sham. Three interventions were performed on each of the athletes at different
time points. Force measurements were obtained by a hydraulic dynamometer immediately
before and after each intervention at the same period before training up to 3 weeks
with at least 36 hours between interventions.
Results
Analysis of grip strength data revealed a statistically significant increase in strength
within the treatment group after the first intervention (6.95% right, 12.61% left)
as compared with the second (11.53% right, 17.02% left) and the third interventions
(10.53% right, 16.81% left). No statistically significant differences were found in
grip strength comparison within the sham group. Overall differences in strength were
consistently significant between the study groups (P = .0025).
Conclusion
The present study suggests that the grip strength of national level judo athletes
receiving chiropractic SMT improved compared to those receiving sham.
