Risk and associated factors for hemiplegic shoulder pain in people with stroke: a systematic literature review

An investigation of upper extremity function, sleep quality, and functional independence in patients with poststroke shoulder pain: a cross-sectional study

BACKGROUND

Poststroke shoulder pain (PSSP) is a common poststroke complication. Even though it is a common phenomenon, it is unclear how it impacts the patient's life.

OBJECTIVE

To investigate the differences in upper extremity function, sleep quality, and functional independence between patients with and without PSSP.

METHODS

This cross-sectional study included 63 participants with stroke (32 patients with PSSP and 31 patients without PSSP). Shoulder pain was evaluated with a Visual Analog Scale and the participants were divided into two groups as those with and without PSSP. The upper extremity function was assessed with the Disabilities of the Arm, Shoulder, and Hand Questionnaire, the Arm Motor Ability Test, and the Nine Hole Peg Test. Sleep quality was assessed with Pittsburgh Sleep Quality Index and the functional independence was assessed with the Functional Independence Measure. All data were analyzed using the program IBM SPSS Statistics 22.0. The Mann-Whitney U test was used to compare the non-normally distributed parameters, and the Chi-square test was used to compare the ordinal variables. The Spearman correlation test was used for the relationship and a linear regression test was used for regression.

RESULTS

Upper extremity function decreased (p < .05), only the sleep disturbance sub-parameter of sleep quality increased (p = .01), and functional independence increased in patients with PSSP (p < .001). There was a moderate relationship between pain and upper extremity function and a fair relationship between pain and sleep quality (use of sleep medications, daytime dysfunction sub-parameters) (p < .05).

CONCLUSIONS

PSSP impairs upper extremity functions, which play an important role in activities of daily living, and reduces functional independence. These results suggest that it is important to evaluate shoulder pain and examine the factors affecting pain in the rehabilitation of patients with stroke.

Prevalence of Hemiplegic Shoulder Pain in Iran: A Systematic Review and Meta-analysis

Context

Hemiplegic shoulder pain (HSP) is one of the complications of a stroke.

Objectives

This study aimed to determine shoulder pain prevalence in cerebrovascular accident (CVA) patients.

Methods

This meta-analysis study searched English and Persian descriptive or descriptive-analytical full-text studies on CVA patients. The search was carried out in all databases by two researchers using keywords such as stroke, pain, CVA, hemiplegic, and shoulder pain. Data analysis was done with the software CMA3.

Results

In the initial search, 109 articles were found, and finally, the data from four articles were analyzed. The prevalence of HSP was 23% (confidence interval (CI) = 10.3% - 43.5%).

Conclusions

Considering the HSP prevalence (28.1%) among CVA patients, it is necessary to carry out rehabilitation interventions to prevent such pain in these patients. It is also suggested that rehabilitation interventions be included in the patient education of the healthcare system.

A Combination of Long-Duration Electrical Stimulation with External Shoulder Support during Routine Daily Activities in Patients with Post-Hemiplegic Shoulder Subluxation: A Randomized Controlled Study

The study objective was to determine the effect of long-duration neuromuscular electric stimulation (NMES) on shoulder subluxation and upper-extremity function during the acute post-stroke stage. Twenty-eight subjects (mean age ± standard deviation -70.0 ± 14.0 years) were randomly assigned to an experimental or to a control group receiving NMES to the supraspinatus and posterior deltoid muscles or sham treatment for 6 weeks. All the subjects continued standard rehabilitation and external shoulder support (EST). Assessments were conducted pre- and post-intervention and at a 2 week follow-up session by an assessor blind to group allocation. Outcome measures included the degree of shoulder subluxation, Fugl-Meyer assessment-upper extremity (FMA-UE) test, FMA-hand and finger subscales, Functional Independence Measure (FIM), and shoulder pain (using the Numeric Pain Rate Scale). Shoulder subluxation was significantly lower, while the FMA-UE and FMA-hand and finger subscales were significantly improved in the experimental group post-intervention and at follow-up compared to the control group. FIM at follow-up improved more in the experimental group. No change was observed in pain level in both groups. Supplementing NMES to standard rehabilitation and EST is beneficial in reducing shoulder subluxation and improving upper-extremity function. Further research is necessary to determine effect of longer treatment duration and longer follow-up periods.
