No, at trial, the parties cannot speak to each other. Doing so can result in a contempt of court. The parties can only speak when asked to by the attorneys, while giving sworn testimony, or the judge.
If the question is directed to the time in the divorce case prior to the actual trial, the answer is yes, the parties may always speak to one another directly. This is done sometimes when parties get tired of the litigation and wish to speak to one another about reconciling their differences be they emotional or financial. The lawyers will probably advise against it, but they have no power to prevent it.
The state in which the alleged incident occurred.
Yes
In a criminal law case there are 6 parties involved. These parties include the victim, the defendant or suspect, the defense attorney, the prosecutor, the judge, and the jury.
Regardless of the situation the person(s) who bring the lawsuit (plaintiff(s)) are the ones who have to prove their case. (In the instance cited by the question that would be the patient.).
civil case
A defendant that is associated by charges that support the charges against the primary defendant(s) but, in and of themselves not part of the case directly. Meaning a charge unrelated to the primary case. For example, a trucking company distributing drugs would be a peripheral defendant against the manufacturing case of their supplier.
The state or prosecutor bears the burden of proof. You are legally innocent until proven guilty.
Plantiff
It depends on the laws of the jurisdiction and the facts of the case. Judges who preside over a divorce case can take and redistribute a defendant's interest in property, can take a portion of the defendant's income for child support, can take the defendant's right to visit with their children under certain circumstances and can also take the defendant's liberty if they refuse to pay child support. Child Support Enforcement can take such things as a tax refund, the right to drive a vehicle and can garnish wages.

Well, the plantiff in a criminal case is (are) the people. So depending on the circumstances the case could be delayed or dismissed, at the perrogative of the judge.
There is no plaintiff in a criminal case. The state prosecutes.
