Pain management in the rehabilitation of stiff shoulder: prospective multicenter comparative study of 193 cases

Prognostic factors of nonsurgical intervention outcomes for patients with frozen shoulder: a retrospective study

PURPOSE

This study aimed to investigate the correlation between mental and physical health-related quality of life and the outcomes of conservative treatment in patients with frozen shoulder (FS).

METHODS

This was a two-center retrospective study. It included 84 consecutive patients who underwent a 3-month treatment comprising education, physical therapy, and corticosteroid-anesthetic injections. Changes in range of motion (ROM) and Shoulder Pain and Disability Index (SPADI) scores, measured at baseline and after 3 months, were selected as dependent variables. Data on age, sex, Body Mass Index, duration of symptoms, dominant affected limb, and Short Form-36 (SF-36) subscales were gathered at baseline and investigated as prognostic factors. Backward stepwise regression models were used to identify significant associations.

RESULTS

At 3-month follow-up, all the patients showed significant improvement. Higher SF-36 General Health, Mental Health and Social Functioning scores at baseline were associated with a greater beneficial change in ROM and SPADI. In contrast, lower SF-36 Bodily Pain and Role Emotional scores were found to be associated with greater improvement.

CONCLUSION

The study findings indicate that the self-perceived mental and physical health of patients have a significant impact on both subjective and objective clinical outcomes and healthcare professionals should take these aspects into account.

Effectiveness of electrophysical agents in subjects with frozen shoulder: a systematic review and meta-analysis

PURPOSE

This systematic review with meta-analysis aimed to assess the effectiveness of electrophysical agents in improving pain, function, disability, range of motion, quality of life, perceived stiffness, and time to recovery in subjects with frozen shoulder (FS).

METHODS

A thorough search of MEDLINE, Cochrane Library, PEDro, and EMBASE yielded 1143 articles, of which 23 randomized controlled trials were included. Risk of bias (RoB) was assessed through Cochrane Risk of Bias 2 tool. The certainty of evidence was evaluated through the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE).

RESULTS

The analysis included a total of 1073 subjects. None of the studies were judged as low RoB. Potentially clinically significant differences were observed in pain at 6 weeks and 5 months after extracorporeal shockwave therapy (ESWT), and in disability up to 3 months with laser therapy, albeit with uncertain results due to the high RoB and to the study heterogeneity. Ultrasound (US) therapy did not yield significant differences in any outcomes. The certainty of evidence was very low.

CONCLUSIONS

Based on the high heterogeneity and low quality and certainty of evidence, ESWT, laser, and US cannot be recommended for FS treatment. Caution should be exercised in interpreting the findings.

Positive Effect of Manipulated Virtual Kinematic Intervention in Individuals with Traumatic Stiff Shoulder: A Pilot Study

Virtual reality enables the manipulation of a patient’s perception, providing additional motivation to real-time biofeedback exercises. We aimed to test the effect of manipulated virtual kinematic intervention on measures of active and passive range of motion (ROM), pain, and disability level in individuals with traumatic stiff shoulder. In a double-blinded study, patients with stiff shoulder following proximal humerus fracture and non-operative treatment were randomly divided into a non-manipulated feedback group (NM-group; n = 6) and a manipulated feedback group (M-group; n = 7). The shoulder ROM, pain, and disabilities of the arm, shoulder and hand (DASH) scores were tested at baseline and after 6 sessions, during which the subjects performed shoulder flexion and abduction in front of a graphic visualization of the shoulder angle. The biofeedback provided to the NM-group was the actual shoulder angle while the feedback provided to the M-group was manipulated so that 10° were constantly subtracted from the actual angle detected by the motion capture system. The M-group showed greater improvement in the active flexion ROM (p = 0.046) and DASH scores (p = 0.022). While both groups improved following the real-time virtual feedback intervention, the manipulated intervention provided to the M-group was more beneficial in individuals with traumatic stiff shoulder and should be further tested in other populations with orthopedic injuries.

Effectiveness of translational manipulation under interscalene block for the treatment of adhesive capsulitis of the shoulder: A nonrandomized clinical trial

Study Design: Nonrandomized controlled trial. Objective: To determine whether translational manipulation under anesthesia/local block (TMUA) adds to the benefit of mobilization and range of motion exercise for improving pain and functional status among patients with adhesive capsulitis of the shoulder (AC). Background: TMUA has been shown to improve pain and dysfunction in patients with AC. This intervention has not been directly compared to physical therapy treatment without TMUA in a prospective trial. Methods: Sixteen consecutive patients with a primary diagnosis of AC were divided into two groups. Patients in the first (TMUA) group received a session of translational manipulation under interscalene block, followed by six sessions of manipulation and exercise. Patients in the comparison group received seven sessions of manipulation and exercise. Outcome measures taken at baseline and 3, 6, 12 months and 4 years included Shoulder Pain and Disability Index (SPADI) scores. Four-year outcomes included percent of normal ratings, medication use, and activity limitations. Results: Both groups showed improved SPADI scores across all follow-up times compared to baseline. The TMUA group showed a greater improvement in SPADI scores than the comparison group at 3 weeks, with no significant differences in SPADI scores at other time points. However, at 4 years, significantly more subjects in the comparison group (5 of 8) had activity limitations versus subjects in the TMUA group (1 of 8). No subject experienced a complication from either intervention protocol. Conclusion: Physical therapy consisting of manual therapy and exercise provides benefit for patients with AC. Translational manipulation under local block may be a useful adjunct to manual therapy and exercise for patients with AC.

Pain, depression and the postoperative stiff shoulder

Background

The surgical repair of shoulder pathologies, including rotator cuff disease and acromio-clavicular joint arthritis, have undergone many technical advances. However the debilitating postoperative stiff shoulder remains a common and significant complication of these surgeries, occurring in 4.9 to 23.2 % of patients undergoing rotator cuff repairs.

The pathology of the pathological postoperative stiff shoulder and its associated condition “frozen shoulder” are poorly understood and both lack formal objective clinical diagnostic criteria. Additionally, although factors associated with the development of idiopathic frozen shoulder have been well described, multiple studies looking at predictors of postoperative stiff shoulder have produced conflicting results. It has been hypothesised that increased pain in the postoperative period, and depression may be predictors of the development of postoperative stiff shoulder.

Method

A prospective cohort study involving 132 consecutive participants. Preoperatively, participants undergoing arthroscopic subacromial decompression and/or excision of the distal clavicle and/or rotator cuff repair will complete questionnaires about their levels of shoulder pain using a numerical rating scale from 0 to 10, and answer a Patient Health Questionnaire – 9 depression questionnaire. Postoperatively, the participants’ pain levels will be self-assessed at two, five and seven days and weeks four, seven and ten. They will complete the depression questionnaire twice, at the time of their routine first and final postoperative appointments with the treating surgeon. At the final appointment, approximately three months postoperatively, the treating surgeon will clinically diagnose participants as having a postoperative stiff shoulder or not. Their shoulders’ range of motion will be measured. The incidence of postoperative stiff shoulder will be determined, both pain and depression will be analysed as predictors for its development and incidences determined by different objective criteria will be compared.

Discussion

This trial will add to clinical understanding of the postoperative stiff shoulder by providing further insight into the incidence of this condition following shoulder surgery and assessing whether perioperative pain and depression can be used as clinical predictors of postoperative stiff shoulder or markers for possible early intervention. This study will also allow the comparison of incidences determined by different objective criteria in the same cohort.
