From the video, shot by Elizabeth Willmann, it is clear Martha neither resisted arrest or assaulted an officer. You can then hear her shout, "You're hurting me" as she appeared ready to stand as the arresting DPS officer grabbed her arm and lifted her out of her seat. After being dragged up the stairs she was then shoved into the gallery wall and handcuffed. The crowd immediately reacted and begun yelling at the officers to let her go but you can still hear her say, "I will walk." But by then it was too late on this night. Fortunately I can report she is out of jail.
The woman was sitting quietly observing the proceedings. When the video shows troopers approach her, speak to her for a moment in which she gathers her possessions. The next thing you see is the officer forcibly lifting the woman as she tried to stand. You can hear her tell him he is hurting her. She was charged with assaulting an officer for the crime of being a participating citizen in democracy.
