Addressing Shoulder Weakness in Individuals With Rotator Cuff-Related Shoulder Pain: A Systematic Review With
The Journal of Orthopaedic and Sports Physical Therapy
|February 1, 2026
Summary
Rehabilitation interventions significantly improved strength in individuals with rotator cuff-related shoulder pain (RCRSP). Programs incorporating active exercises or strength training yielded the best results for addressing strength deficits.
Area of Science:
- Orthopedics
- Sports Medicine
- Physical Therapy
Background:
- Rotator cuff-related shoulder pain (RCRSP) is a common condition affecting shoulder function.
- Strength deficits are a key component of RCRSP, impacting daily activities and athletic performance.
- Effective rehabilitation strategies are crucial for managing RCRSP and restoring shoulder strength.
Purpose of the Study:
- To systematically review and meta-analyze the effects of rehabilitation interventions on objective strength outcomes in adults with RCRSP.
- To determine the impact of different types of rehabilitation exercises on various shoulder strength measures.
- To provide evidence-based recommendations for optimizing strength recovery in RCRSP patients.
Main Methods:
- Systematic review and meta-analysis of 28 clinical trials and cohort studies.
- Inclusion criteria: interventions lasting ≥6 weeks, objective strength outcomes, adults with RCRSP (excluding other pathologies or post-surgery).
- Meta-analyses used standardized mean difference (SMD) from baseline to primary follow-up, grouped by strength test direction.
Main Results:
- Rehabilitation interventions demonstrated moderate effects on external rotation strength (SMD=0.56) and small-to-moderate effects on abduction, internal rotation, flexion, and scaption strength.
- Interventions including strength training or active exercises showed significant improvements across all strength outcomes.
- Rehabilitation programs without exercises or strength training yielded no discernible effects on strength.
Conclusions:
- Rehabilitation interventions are effective in improving strength for individuals experiencing rotator cuff-related shoulder pain.
- Active exercises and strength training components are essential for successful rehabilitation and addressing strength deficits in RCRSP.
- Clinicians should prioritize incorporating these elements into treatment plans for RCRSP patients.

01:23Muscles of the Shoulder
9.1K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially and so are classified as weak bases. These types of compounds are also abundant in nature and important commodities in various technologies. For example, global production of the weak base ammonia is typically well over 100 metric tons annually, being widely used as an agricultural fertilizer, a raw material for chemical synthesis of other...

Few compounds act as strong acids. A far greater number of compounds behave as weak acids and only partially react with water, leaving a large majority of dissolved molecules in their original form and generating a relatively small amount of hydronium ions. Weak acids are commonly encountered in nature, being the substances partly responsible for the tangy taste of citrus fruits, the stinging sensation of insect bites, and the unpleasant smells associated with body odor. A familiar example of a...

01:08Titration of a Weak Acid with a Weak Base
4.9K
Weak acids and bases do not undergo dissociation completely, and titrations between these two are rarely studied. When such studies are performed, say, for the titration of a weak acid with a weak base, the titration curve plots the change in pH as a function of the volume of base added. Take the titration of acetic acid with ammonia, for instance. During the titration, these two species form ammonium acetate and water, but the pH change is slow and gradual.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...
