Baseline attenuated muscle (BAM) method

Abstract

In a method of strengthening pathological muscles, the patient is subjected to a therapeutic strengthening exercise for strengthening a target muscle. The method begins at the start of the strengthening exercise in response to exacerbation of symptoms exhibited by patient. The symptoms exhibited by the patient during the strengthening exercise are minimized by a series of steps including adjusting an intensity of the strengthening exercise, limiting a range of motion of the strengthening exercise, dividing evenly a prescribed number of sets and repetitions corresponding to the strengthening exercise, dividing unevenly the prescribed number of sets and repetitions corresponding to the strengthening exercise, varying a speed at which the patient is subjected to the strengthening exercise, modifying a position of the patient for the strengthening exercise, matching a mode of the strengthening exercise to the modified patient's position, and switching between primary, secondary and tertiary actions of the patient's target muscle.

(14) 8. Switch to the target muscle's secondary or tertiary action or the target action's secondary or tertiary movers (Step 8). If symptomatic, return to Step 1, otherwise continue to next step (Go to FIG. 4 and continue).

(15) Referring to FIG. 4, upon successful completion of any step, go to Stage I and continue with exercise until completion at Stage II. However, if symptoms arise after the successful modification during the exercise, go to Stage III, increase rest periods and or decrease speed at which the exercise is performed. Continue until the exercise is completed at Stage II or stop exercise as not to overwork the BAM muscle (Stage IIIa). If symptoms do not resolve exercise prescription is complete for session. Any further exercise will be intolerable for patient. Record successful sets and repetitions (Stage IIIb).

(16) Stages I, II, III, IIIa and IIIb shown in FIG. 4 are further described below:

(17) Stage I: Symptoms after successful completion. Upon successful completion of any step,

(18) Stage II: Complete exercise until completion.

(19) Stage III: However, if symptoms arise during the exercise increase rest periods and or decrease speed at which the exercise is performed.

(20) Stage IIIa: Stop exercise as not to overwork the BAM muscle. If symptoms do not resolve exercise prescription is complete for session. Any further exercise will be intolerable for patient.

(21) Stage IIIb: Record successful sets and repetitions.

(22) Examples of the BAM Method are presented below using Patient A and Patient B. In the examples, Patient A will achieve success at step 4 while Patient B will achieve success at step 7. In addition, Patient B will be given an alternate scenario in which step 7 is unsuccessful. Patient B will then proceed to step 8.

(23) In the following procedural example, Patient A is receiving a prescription of therapeutic exercise from a physical therapist for his shoulder. The prescribed exercise is standing shoulder flexion with a dumbbell 0-90 degrees range of motion. In this example Patient A will move through Steps 1-4, where Patient A will achieve success at Step 4.

(24) Start the Strengthening Exercise

(25) 1. In Step 1, the therapist adjusts the prescription by increasing or decreasing the intensity or weight using a perceived rating of exertion scale where 100% is maximum effort and 0% is no effort at rest. The target progressive resistive exercise without exacerbation of signs or symptoms should be 60%-70% perceived rating of exertion. Patient A is using a 1 pound dumbbell at a 60%-70% perceived rating of exertion, however, the exercise is painful in the upper half of the range of motion. 2. For Step 2, patient A achieves symptom free shoulder flexion in a fraction of the 0-90 degree range of motion. The exercised range of motion is equal to 54 degrees (60%-70% of the exercises full range), which is rounded to 55 degrees. Patient A proceeds to next step. 3. In Step 3, patient A performs shoulder flexion without symptoms, yet the symptoms exacerbate after 5 repetitions. The prescribed number of sets and repetitions (6×5), which can be performed without the exacerbation of any symptoms. However, Patient A can only complete 4 sets of 5 repetitions without pain. Patient A proceeds to next step. 4. In Step 4, patient A is prescribed 4 sets of 5 repetitions, 2 sets of 3 repetitions and 2 sets of 2 repetitions (Any multiples to reach the target work volume of 30 repetitions). During the unevenly distributed sets and repetitions, Patient A requires increased rest periods to complete the exercise without exacerbation of symptoms. Patient A is successful.

(26) Upon successful completion of any step, go to Stage I and continue with exercise until completion at Stage II. However, if symptoms arise after the successful modification during the exercise, go to Stage III, increase rest periods and or decrease speed at which the exercise is performed. Continue until the exercise is completed at Stage II or stop exercise as not to overwork the BAM muscle (Stage IIIa). If symptoms do not resolve exercise prescription is complete for session. Any further exercise will be intolerable for patient. Record successful sets and repetitions (Stage IIIb).

(27) In the next procedural example, Patient B is receiving a prescription of therapeutic exercise from a physical therapist for her hip. The target progressive resistive exercise without exacerbation of signs or symptoms should be 60%-70% perceived rating of exertion. Patient B, is using a plate loaded isokinetic pulley machine set to 20 pounds to perform standing hip extension at 0-15 degrees range of motion at a 60%-70% perceived rating of exertion. The exercise is painful throughout the whole range of motion. In the example, Patient B will proceed through steps 1-7. Patient B will achieve success by step 7. In addition, an alternate scenario at step 7 will be given where Patient B must proceed to step 8 to achieve success.

(28) Start the Strengthening Exercise

(29) 1. In Step 1, adjust by increasing or decreasing the intensity or weight using a perceived rating of exertion scale where 100% is maximum effort and 0% is no effort at rest. The target progressive resistive exercise without exacerbation of signs or symptoms should be 60%-70%. Patient B, is using 20 pounds at 60%-70% perceived rating of exertion, but the exercise is painful in the whole range of motion of 0-15. The physical therapist adjusts the exercise prescription by decreasing the weight to 10 pounds, without success. Patient B proceeds to next step. 2. For Step 2, Patient B is unable to achieve symptom free resistive hip extension despite any modifications of range of motion. Patient B proceeds to next step. 3. For Step 3, Patient B is unable to achieve symptom free resistive hip extension despite any modifications of dividing the prescribed number of sets and repetitions evenly. Symptoms are still present. Patient B proceeds to next step. 4. For Step 4, Patient B is unable to achieve symptom free resistive hip extension despite any modifications of dividing the prescribed number of sets and repetitions unevenly. Step 4 is not successful. Symptoms are still present. Patient B proceeds to next step. 5. For Step 5, Patient B is unable to achieve symptom free resistive hip extension despite any modifications of changing the speed from 90 degrees per second to 60 degrees per second. Other multiple variations of speed are also unsuccessful. Symptoms are still present. Patient B proceeds to next step. 6. In Step 6, the physical therapist adjusts the exercise prescription to perform the exercise supine. 7. In Step 7, the physical therapist then matches the appropriate exercise mode for the position adjustment. Exercise tubing is attached to the patient's ankle. The patient performs hip extension by pulling on the band with his leg starting at 50 degrees of flexion range of motion to 0 degrees range of motion (neutral). The patient is successful. In an alternate scenario, Patient B is unsuccessful at step 7. Patient B proceeds to step 8. 8. In Step 8, if hip extension elicits pain from the primary action of the gluteus maximus, then switch to external rotation the secondary action of the gluteus maximus. Patient B proceeds back to step 1.

(30) Upon successful completion of any step, go to Stage I and continue with exercise until completion at Stage II. However, if symptoms arise after the successful modification during the exercise, go to Stage III, increase rest periods and or decrease speed at which the exercise is performed. Continue until the exercise is completed at Stage II or stop exercise as not to overwork the BAM muscle (Stage IIIa). If symptoms do not resolve exercise prescription is complete for session. Any further exercise will be intolerable for patient. Record successful sets and repetitions (Stage IIIb).

(31) The BAM Method Achieves the Following Benefits: Maximizes strengthening benefits: The BAM Method maximizes strengthening benefits by allowing an increased tolerance for therapeutic exercise. Improves patient compliance: A treatment's effectiveness is directly related to tolerance and compliance of the treatment. By minimizing the symptoms, especially pain, it attenuates the inhibitory effects of pain. Improves rates of success: If a patient is able to tolerate and is compliant with the treatment, the treatment's rate of success will increase.
