PMID 33094667WHAT IT FOUND
Early functional rehabilitation exercises for Achilles tendon ruptures are poorly described in research.
Most studies omit critical dosage details like load and repetitions, making it nearly impossible for therapists to replicate proven protocols or compare outcomes across different treatments.
Key findings
01The majority of resistance exercise interventions lacked essential dosage details, with only a small fraction reporting load, repetitions, and sets.
02A significant portion of exercises could not be categorized due to vague descriptions, leaving clinicians unsure of the actual treatment provided.
03Reporting quality did not improve over time, with no significant association between publication year and the completeness of exercise descriptions.

What it does not show
The review excluded studies with fewer than 10 patients, which may miss emerging pilot data. The eight-week cutoff for 'early' rehabilitation was arbitrary and based on clinical experience rather than a physiological definition. Many included studies were published before modern reporting guidelines existed, which may explain poor descriptions rather than poor practice. The review focused on the description of exercises, not their efficacy, so it cannot tell you which exercises work best, only that we don't know exactly how they were performed.
Declared interests
The authors declared no conflicts of interest. The review was conducted with assistance from a research librarian, and data management software was used, but no commercial funding sources were identified in the text.
The easy way to misread this
Do not interpret the poor reporting as evidence that early functional rehabilitation is ineffective or unsafe. The study shows that researchers failed to describe what they did, not necessarily that the treatment itself was flawed. Use this finding to advocate for better documentation in your own practice and to approach published protocols with skepticism regarding their exact dosage.
