Prescriptive & PragmaticPrescriptive Mobilization Versus a Pragmatic Mobilization

The prescriptively applied non-thrust manipulation will be involve a central lumbar posterior-anterior directed at L4 and L5. "The therapist will place the hypothenar eminence of 1 hand over the spinous process of L4. With the elbows remaining extended, the therapist will deliver a low-velocity, high amplitude oscillatory force (at approximately 2 Hz) directed at L4 for a total 60 seconds (Figure 1)". Following a 30-second rest the therapist will perform a similar set of oscillations directed at L5. A second set of oscillations will then be performed in a similar manner at L4 and L5. Patients will be seen for 4 visits.

The pragmatically applied non-thrust manipulation will be based on the original concepts outlined by Maitland and will of consist of passive, low velocity, oscillatory movements within the physiological range of the joint, applied to the comparable spinal level of the patient (defined as the spinal level that reproduced the patient's familiar pain). The techniques will be modified based on clinician assessment and patient feedback and consist of Grade I through Grade IV movements. Since the pragmatic approach is clinician-driven, no time limit will be placed on the application and the number of mobilizations used will depend on the patient feedback (the exact definition of a pragmatic treatment). Patients will be seen for 4 visits.

Although not described in the original article, we'll target Grade III mobilizations. The procedure will be completed during a session after 2 sets of 60 seconds of non-thrust oscillatory manipulations will be performed over L4 and L5." Patients will be seen for 4 visits.

The techniques will of consist of passive, low velocity, oscillatory movements within the physiological range of the joint, applied to the comparable spinal level of the patient (defined as the spinal level that reproduced the patient's familiar pain). The techniques will be modified based on clinician assessment and patient feedback and consist of Grade I through Grade IV movements. Common techniques used may include unilateral posterior-anterior movements, central posterior-anterior movements, and sidelying rotations (without thrust). Since the pragmatic approach is clinician-driven, no time limit will be placed on the application and the number of mobilizations used will depend on the patient feedback (the exact definition of a pragmatic treatment).
