Adjunctive ROM Therapy: Home-Based Rehab

The Problem: When Joint Stiffness Persists

Persistent range of motion (ROM) loss following injury, surgery or illness is a challenging problem affecting many patients. Adjunctive ROM therapy devices are commonly added to a traditional course of hands-on therapy for patients who demonstrate delays in gaining ROM or persistent joint stiffness following injury or surgery.

The Solution: More Dosage of Stretch

When adequate ROM gains are not being made with standard  physical or occupational therapy, more dosage of therapeutic end range stretch is the solution. ROM therapy devices are designed to provide the necessary dosage of low intensity, prolonged duration stretch to shortened connective tissues [at their end range] to achieve permanent tissue elongation. The physiologic basis of using ROM therapy devices to increase joint ROM is supported by the biomechanical principle that low load, prolonged stress applied at end range [of motion] will remodel and lengthen shortened tissue.

Static Progressive Stretch (SPS) and Dynamic Splinting (DS) devices provide effective home-based stretch therapy to treat joint stiffness, and are best used to augment in-clinic therapy.

SPS and DS are time honored and proven treatment techniques, used to permanently stretch shortened connective tissues and restore joint mobility. Both SPS and DS work by applying low intensity, long duration stretch to achieve physiologic remodeling of affected joint tissues. However each does so with differing stretch forces and treatment protocols.

What is Static Progressive Stretch?

SPS devices use inelastic components (static line, screws, and gears) to apply stress-relaxation (SR) loading to stiff tissues. SR loading utilizes a low-intensity force to position a joint at its end range [of motion] and hold joint tissues at their maximal therapeutic length. As tissues lengthen in response to the applied stress, the SPS device is adjusted to position the joint tissues at their new maximal therapeutic length. This process of stretching and holding is repeated several times during a treatment session, and sessions are performed daily to achieve steady increases in joint ROM. Stress-relaxation is the very same force load that forms the basis for manual therapy stretching techniques and turnbuckle orthosis therapy.

JAS SPS requires less device wear time. Shorter treatment time means better patient compliance – and more time for active living! Biomechanical studies show SR loading as the most efficient way to produce a permanent elongation of soft tissue. Numerous published peer reviewed studies support a JAS SPS device wearing protocol of three 30-minute sessions per day for optimal results.

JAS SPS is proven effective. Over 30 published, peer-reviewed studies show successful rehab outcomes with JAS SPS device therapy – including preventing the need for manipulation under anesthesia or surgery to correct joint contracture.

What is Dynamic Splinting?

Dynamic splinting uses an integrated tension spring to apply creep-based (CB) loading to stiff tissues in order to achieve tissue remodeling or lengthening. CB loading refers to the lengthening that occurs when the joint tissues are held under a constant load over time. Dynamic splints apply a constant, low-intensity force to tissues at their therapeutic end range (of motion) for a prolonged treatment session. As tissues lengthen in response to the applied stress during DS therapy sessions, the spring of the DS continuously adjusts to seek the new therapeutic end range.

Suggested wearing protocols for Dynamic splints, such as the JAS Dynamic and JAS Advance Dynamic ROM product lines, range from 3-12 hours of continuous use per day, per direction of motion loss. This wearing schedule has been recommended to achieve optimal and permanent gains in ROM, and is supported by multiple scientific and clinical studies for over 30 years.
