Six-week sling immobilization,
does it really help with Reduced 12-month ultrasound retear versus early pain-limited active motion?
research showsThe grade is D with 30 points. In a 206-participant randomized trial, full-thickness retear among the 165 who completed 12-month ultrasound was 30% with early motion versus 33% with strict immobilization, P>0.8. Imaging retear was not a registered primary outcome, and 20% lacked ultrasound follow-up.
ads claimRestricting motion and reducing certain movements across a repair are physical facts. They do not automatically establish better tendon healing or fewer retears.
Useful facts when choosing a product
- The standard group wore a sling for six weeks and avoided active range of motion.
- The early group self-weaned according to pain and comfort and used pain-free active motion.
- Repair status was assessed by ultrasound at 12 months, completed by 165/206.

What the research actually shows
Sheps and colleagues with SURGE randomized 206 full-thickness rotator cuff repair patients, 103 per group. Early participants self-weaned from the sling and performed pain-free active motion in the first six weeks; standard participants wore a sling for six weeks with no active motion. Assessors were masked and analysis followed assignment, but ultrasound was completed by only 79 versus 86 participants. NCT01333527 lists WORC and range of motion as primary outcomes.
Why this is classified as D (30)
A null imaging surrogate, 20% missing ultrasound, and no counted independent replication of the exact six-week active-motion comparison give D with 30 points.
Counterpoint. Smaller tears, different repairs, passive-only protocols, and four-week immobilization are different interventions and were not counted as direct replication.

| Endpoint | S | Surrogate marker - laboratory or imaging measures |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |

Stored derived and displayed grades match; this is not a current recalculation or validity check (D).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Six weeks of strict sling immobilization reduces 12-month ultrasound retear | D | Rates were 30% versus 33%, P>0.8. |
| Early active motion worsens long-term pain or function | D | Pain, strength, and quality of life did not differ through 24 months. |
