Q. What is the SLINGPROM®?
The SLINGPROM® is the only patented device shoulder pulley system that allows the pulley to provide Passive Range of Motion (PROM).
Q. What is Passive Range of Motion and why is it Important?
Passive Range of Motion is when the joint(in this case the shoulder) is moved with minimal muscle activation.
(PROM) is an important phase of Rehab that provides joint lubrication and nutrition while helping to elongate collagen fibers necessary for proper joint motion.
While most (PROM) is provided by the patient's therapist manually, it often difficult for the patient to relax. When a patient is in pain, he or she often subconsciously "Guards" the injured area.
This guarding actually INCREASES activation of the very shoulder muscles we are trying Not to activate. This leads to more pain and then more guarding.
The SLINGPROM® was developed to alleviate this problem by giving control back to the patient.
Because the patient is in control, and the injured arm is well protected, the patient relaxes and (PROM) increases without an increase in pain!
Q. Why would you need a SLINGPROM®?
A typical shoulder pulley is traditionally utilized for Active Assisted Range of Motion (AAROM). However, there are many therapists and physicians who use a standard pulley for (PROM).
This is controversial, and evidence does not support its use in this manner. Dockery ET al, found that the use of standard shoulder pulleys activated 17.6% of the supraspinatus muscle vs 8.7% using (AAROM) with a bar and 5% with manual (PROM) or CPM use.*
PLEASE NOTE that this study was performed on healthy, non injured individuals: NO PAIN = No GUARDING.
Q. How is the SLINGPROM® different than a standard shoulder pulley ?
With a standard shoulder pulley, you must grip the handle. As you grip you contract the muscles in your forearm, then upper arm and then the muscles in your shoulder. At best, this is Active Assisted Range of Motion (AAROM), at worst, it's Active Range of Motion (AROM). For many surgeries, and Frozen shoulder, early (AAROM) or (AROM) is not ideal.
Q. Why would therapists or physicans use standard pulleys?
Some don't. They rely on standard cane exercises (AAROM) to minimize (AROM). Therapists/physicians that use standard pulleys for (PROM) probably feel that it is their best option. Standard shoulder pulleys are very valuable for (AAROM) and (AROM).
Q. How is The SLINGPROM® different than standard shoulder pulleys?
Traditional shoulder pulleys provide only Active range of motion (AROM) or Active assisted range of motion (AAROM).

Q. What kind of shoulder problems does the SLINGPROM® help**?
Any Shoulder condition that would benefit from (PROM) such as:
Rotator Cuff Repairs
Post Mastectomy ROM loss
Total Shoulder Replacements
