PER CURIAM.
      Following an adverse jury verdict on battery and negligence claims, Stacy
Kellar appeals the district court’s1 sua sponte pre-trial dismissal of her claims of false
imprisonment and intentional infliction of emotional distress (IIED) against several
employees (defendants) at the Mountain Park Boarding Academy (MPBA).

        The district court dismissed Kellar’s false-imprisonment and IIED claims at a
hearing on defendants’ motions in limine to bar evidence crucial to those claims.
Because the court considered evidence outside the pleadings, we view the dismissals
as effectively a sua sponte grant of partial summary judgment. See Kuhn v. Nat'l
Ass’n of Letter Carriers, Branch 5, 

, 770 n.4 (8th Cir. 1976) (treating
dismissal as summary judgment because matters outside pleadings were considered).
Kellar had notice and an opportunity to oppose the dismissal of her claims because she
was aware of defendants’ affirmative defenses to the claims, she fully responded to
defendants’ motions in limine, and she argued the viability of her claims at the pre-
trial hearing. We therefore hold that it was not reversible error for the court to grant
summary judgment sua sponte. See Hubbard v. Parker, 

, 531 (8th Cir.
1993) (district court may sua sponte grant summary judgment under Fed. R. Civ. P.
56 as long as party against whom judgment was entered was given sufficient advance
notice and adequate opportunity to show why summary judgment should not be
granted); cf. Madewell v. Downs, 

, 1048 (8th Cir. 1995) (where court
converted defendant’s request for dismissal into motion for summary judgment, lack
of formal notice was harmless because nonmoving party had adequate opportunity to
respond to motion, and material facts were neither disputed nor missing from record;
plaintiff had constructive notice that right of defendants to judgment as a matter of law
was at issue).




      1
        The Honorable Charles A. Shaw, United States District Judge for the Eastern
District of Missouri.

                                           -2-
       We conclude that, even when the record is viewed in the light most favorable
to Kellar, defendants are entitled to judgment as a matter of law on her false-
imprisonment claim because Kellar cannot genuinely dispute the fact that her mother
consented to her enrollment at MPBA with full knowledge of MPBA’s programs and
restrictions. See Blair v. Wills, 

, 828-29 (8th Cir. 2005) (de novo review
of grant of summary judgment; false imprisonment occurs under Missouri law when
plaintiff is confined without his consent and without legal justification; although
Missouri courts have not addressed specifically whether private school may be liable
for false imprisonment when custodial parent consents to child’s enrollment and
attendance at school, plaintiff cannot maintain an action when parents consented to
enrollment at boarding school with full knowledge of school’s programs and
restrictions, because under Missouri statutory law, parents exercise authority over
custody, care, and management of their children, and may delegate that authority on
behalf of their minor children), cert. denied, 

(2006); Dairy Farmers
of Am., Inc. v. Travelers Ins. Co., 

, 572 (8th Cir. 2002) (applying Erie
doctrine).

       To the extent Kellar asserts that her mother was defrauded by MPBA officials
and would not have consented to enrolling Kellar at MPBA had she been aware of
how Kellar would be treated, we conclude that the issue was not properly before the
district court because it was a new theory of liability, not asserted in her complaint.
See Woods v. Wills, 

, 1186 (E.D. Mo. 2005) (party cannot assert
new theory of case in defending summary judgment motion or expand claim in
attempt to create material issue of fact where none existed before).

       Regarding Kellar’s IIED claim, her expert witness, Dr. Jeffrey Kline, Ph.D.,
conceded that he is a psychologist, not a medical doctor, and does nothing related to
the practice of medicine. Therefore, we conclude that the court did not abuse its
discretion in excluding his non-medical testimony concerning Kellar's alleged
emotional distress. See United States v. Radtke, 

, 840 (8th Cir. 2005)

                                         -3-
(court reviews exclusion of evidence for abuse of discretion); United States v. Malik,

, 1001 (8th Cir. 2003) (citing Fed. R. Evid. 103(a) (2000)) (once district
court makes definitive ruling excluding evidence, party does not need to renew
objection to preserve claim of error for appeal); Gordon v. City of Kansas City, Mo.,

, 1004 (8th Cir. 2001) (under Missouri law, to recover for emotional
distress where no physical injury is involved there must be expert medical testimony
that emotional distress or mental injury was medically significant).

       We further hold that the district court did not commit reversible error in
granting summary judgment for defendants on Kellar’s IIED claim because, without
Dr. Kline’s testimony, Kellar could not create a genuine issue of fact as to whether she
suffered a medically diagnosable and medically significant emotional injury. See Bass
v. Nooney Co., 

, 772-73 (Mo. banc 1983) (absent allegation of
physical injury, plaintiff cannot prevail on IIED claim unless she demonstrates
“emotional distress or mental injury” which “must be medically diagnosable and must
be of sufficient severity so as to be medically significant”).

      Accordingly, we affirm.
