Coaching and Therapist Attitude
The first, and most important thing for a therapist to determine about coaching, is whether a patient wants and could benefit from coaching. This is truly idiosyncratic. There are three general situations during EMG biofeedback that you have to be prepared for:
Situation 1 - The patient has decreased forehead muscle tension levels. Possible responses are:
a) Thats fantastic! Keep up the good work. I want you to remember what you are doing now so you can tell me at the end of the session. Real good! Try to get it even lower. Situation 2 - The patient has not been able to decrease forehead muscle tension levels. Possible responses are: Thats OK. Its as important to find out what makes it go up as it is to find out what makes it go down. I want you to remember what youre doing now so you can tell me at the end of the session. Thats OK. You can only go up so far before you have to start going down. You seem to be going up; you might want to switch to a different strategy. Situation 3 - The patient seems frustrated or appears to be trying too hard. Possible responses are: Thats to be expected. Remember, I told you that this is a very difficult response to get. If it was easy, you wouldnt need me or the machines. Lets take a break. Sometimes all you need is a few minutes to clear your mind and then you come back like gangbusters. You may want to think of yourself as a scientist, who dispassionately tests theories and tosses them in or out depending on whether or not they work. As a rule, we would suggest that coaching be done in a limited basis, as this will help to generalize the response to the real world, for in everyday situations patients do not have a therapist accompanying them. It is imperative for the therapist to convey as enthusiastically as possible to the patient that he or she is doing well in the biofeedback session.
Home practice has traditionally been considered an essential aspect of all psychophysiological interventions for chronic tension headache(8,12). Home practice can be conducted in many ways: The simplest form of homework is to instruct the patient to practice the office strategy that seemed to work the best at home and in other real world locations such as the job, supermarket, etc. (we usually instruct them to do so at least four times a day). The use of a home practice EMG unit, such as the MyoTrac(TM), is also quite helpful. An important application for the MyoTrac(TM) EMG is to use it in situations which generally initiate headaches. For example, computer operators might monitor muscle activity while typing, using the delayed threshold function (internal switch positions at OFF/ON/ABV/WIDE) which provides a tonal warning only when the threshold level has been exceeded for more than 4 seconds. In this way, maintained muscle tension is minimized, while appropriate low levels of muscle activity is reinforced.
Generalization involves preparing the patient to carry the learning that may have occurred during the biofeedback session into the real world. The most common method, by far, is a self control condition which is interspersed between a baseline and a feedback condition. The self control condition involves asking the patient to control the desired psychophysiological response (e.g., "Please try to lower your forehead muscle tension") without any feedback. If the patient can control the response, the clinician may assume that there has been between-session learning (i.e., generalization). Another method of testing for generalization is to present a pre- and post-treatment stressor to the patient and, if there is less arousal during and after a stressor in the post treatment, the clinician may infer that generalization has occurred. A third way of preparing the patient to generalize the biofeedback response is to try to make the office biofeedback training as close to real world situations as possible, such as switching to an uncomfortable chair or standing during the session.
Biofeedback for tension headache in the elderly
Based upon the research (4,5,6) and our clinical experience we would suggest the following when working with the elderly tension headache patient: First, to be certain that the patient understands the therapists instructions, we would suggest requesting each patient to verbally repeat each sessions instructions. Second, therapists should talk at a somewhat slower rate than usual to insure that rationale and instructions are comprehended. Third, the therapist should make every attempt to simplify the instructions and, especially, to avoid the use of sophisticated language or jargon. Fourth, a brief summary of previously imparted information should be given at subsequent sessions to aid patients in retaining details. Fifth, turn up the biofeedback auditory feedback volume to ensure the patient can hear it, or use an earphone. We would also suggest moving the visual feedback monitor closer to ensure that the patient does not have to strain to see it. Finally, be patient with the elderly headache sufferer. Spend some extra time listening; do not communicate a desire to hurry the session. Schedule appointments for 10 minutes longer than usual.
A biofeedback - behavioral program to assist headache patients to decrease both the severity and frequency of headaches has been described. The program includes in-clinic training as well as the inclusion of EMG portable home trainers to provide reinforcement of behavioral and muscle control strategies in the real world.
