A jury rendered a verdict in favor of Rick G. Hawkes (plaintiff) and against Casino Queen,Inc. (defendant), for injuries sustained by plaintiff while using the restroom aboard defendant'scasino cruise ship. Defendant now appeals. The issues for review are as follows: (1) whether thecircuit court erred in prohibiting defendant from performing a psychiatric examination upon plaintiff,(2) whether the court erred in granting plaintiff's motion in limine, which prevented the admissionof evidence of plaintiff's prior injuries, (3) whether the circuit court erred in denying defendant'smotion for a directed verdict at the close of plaintiff's case, (4) whether the circuit court erred insubmitting certain jury instructions, (5) whether the jury's award of damages was against the manifestweight of the evidence, and (6) whether the circuit court erred in denying defendant's motion for ajudgment notwithstanding the verdict. We affirm.

On November 12, 1994, plaintiff boarded defendant's casino for an afternoon cruise. Duringhis visit plaintiff entered the men's restroom. While in the restroom, plaintiff tripped and fell to thefloor, sustaining injuries to his head, neck, and back. Plaintiff was later taken by ambulance to St.John's Mercy Hospital for medical treatment. After being released from the hospital, plaintiffreceived medical care from Dr. David Schreiber for head, neck, and shoulder pain, as well as forweakness in his arms and inability to grip. Dr. Schreiber eventually referred plaintiff to Dr. GeorgeSchoedinger, an orthopedic surgeon. Dr. Schoedinger diagnosed plaintiff as suffering from aruptured disc at the C5-C6 level and later performed an anterior cervical discectomy and fusion uponhim. Dr. Schoedinger believed that plaintiff's ruptured disc, or the symptoms he experienced thatnecessitated his surgery, had been caused by his November 12, 1994, fall. Plaintiff also received asubmuscular ulnar nerve transposition, performed by Dr. David Haueisen, to cure cubital tunnelsyndrome also caused by the fall.
