Résumé
Persistent strength deficits secondary to Achilles tendinopathy (AT) have been postulated to account for difficulty engaging in tendon-loading movements, such as running and jumping, and may contribute to the increased risk of recurrence. To date, little consensus exists on the presence of strength deficits in AT. Consequently, researchers are uncertain about the appropriate methods of assessment that may inform rehabilitation in clinical practice.

Two independent reviewers searched 9 electronic databases using an agreed-upon set of key words.

The Critical Appraisal Skills Programme Case-Control Study Checklist was used to assess the risk of bias for the included studies. A total of 19 studies were eligible.

BACKGROUND
BACKGROUND
Persistent strength deficits secondary to Achilles tendinopathy (AT) have been postulated to account for difficulty engaging in tendon-loading movements, such as running and jumping, and may contribute to the increased risk of recurrence. To date, little consensus exists on the presence of strength deficits in AT. Consequently, researchers are uncertain about the appropriate methods of assessment that may inform rehabilitation in clinical practice.
OBJECTIVE
OBJECTIVE
To evaluate and synthesize the literature investigating plantar-flexion (PF) strength in individuals with AT.
STUDY SELECTION
METHODS
Two independent reviewers searched 9 electronic databases using an agreed-upon set of key words.
DATA EXTRACTION
METHODS
Data were extracted from studies comparing strength measures (maximal, reactive, and explosive strength) between individuals with AT and healthy control participants or between the injured and uninjured sides of people with AT. The Critical Appraisal Skills Programme Case-Control Study Checklist was used to assess the risk of bias for the included studies.
DATA SYNTHESIS
RESULTS
A total of 19 studies were eligible. Pooled meta-analyses for isokinetic dynamometry demonstrated reductions in maximal strength (concentric PF peak torque [PT] slow [Hedges
CONCLUSIONS
CONCLUSIONS
Individuals with AT demonstrated strength deficits compared with the uninjured side or with asymptomatic control participants. Deficits were reported across the strength spectrum for maximal, reactive, and explosive strength. Clinicians and researchers may need to adapt their assessment of Achilles tendon function, which may ultimately help to optimize rehabilitation outcomes.
