Dosage of joint mobilization for the management of patients with rotator cuff-related shoulder pain: A scoping review.

BACKGROUND: Evidence supporting type and dosage of joint mobilizations and rationale for selecting joint mobilization dosage for patients with rotator cuff-related shoulder pain are limited.

OBJECTIVES: This scoping review aimed to systematically map the type and dosage of joint mobilizations used in previous trials for managing patients with rotator cuff-related shoulder pain; and summarize the rationale for adopting a specific joint mobilization dosage.

METHODS: We searched six databases. We included randomised controlled trials using joint mobilization for patients with rotator cuff-related shoulder pain. We extracted data regarding technique, treatment joint mobilization dosages and rationale for a specific dosage.

RESULTS: We included 32 studies. Most studies did not or partially report technique (67%) and within-session dosage (64%) of passive joint mobilization. Overall treatment was fully reported in 95% of studies. The dosage used for passive joint mobilization was heterogeneous (ranging from grade I to grade V). Most studies (85%) did not or partially report technique of mobilization with movement (MWM), whereas within-session and overall treatment dosages were fully reported in more than 85% of studies. Three sets of 10 repetitions were commonly used within-session dosage for MWM. We found very limited information on the rationale for selecting dosage of joint mobilization.

CONCLUSION: We found limited information about the dosage or the rationale for selecting joint mobilization, with a heterogeneous dosage being tested across trials. Our findings highlight the importance of detailed reporting for dosage and rationale for selecting a specific dosage of joint mobilization.
