RangeMaster BlueRanger Shoulder Pulley

Six-dimension breakdown

Why this scored 62/100

RangeMaster (OPTP-adjacent PT-channel brand) BlueRanger Shoulder Pulley is a classic post-surgical and rehabilitation tool used for passive-range-of-motion (PROM) and active-assisted-range-of-motion (AAROM) shoulder work — the standard intervention for post-rotator-cuff-repair, post-shoulder-arthroplasty, adhesive-capsulitis (frozen shoulder), and chronic shoulder-mobility limitations. The door-mounted pulley system uses the uninvolved arm to assist the involved arm through elevation, flexion, and abduction ranges, with the pulley bracket providing mechanical advantage and controlled range. Evidence base for pulley-assisted shoulder mobility is solid within its clinical role: multiple post-operative rehab protocols and RCTs include pulley work as a core PROM/AAROM component in the early rehabilitation phase, particularly for frozen shoulder where progressive mobility work is the primary intervention (Diercks 2004, Neviaser 2011 review). Effect is directly on range of motion, and improved ROM is a clinically meaningful outcome for the target users. Build quality on RangeMaster is institutional-PT-grade with metal bracket and nylon strap options for door mounting. Standard 62 reflects legitimate clinical tool used correctly, with the practical caveat that home use without PT-directed progression can produce diminishing returns or provoke pain if pushed too hard. Would move to Verified 70+ with a companion progression protocol, extended warranty, and published clinical-outcome data for home-use variants.

Evidence & sources

The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.

Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

How to read the Evidence dimension

• 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
• 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
• 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
• 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
• 0–19: No credible evidence base or unverifiable claims.
