Posterior Shoulder Tightness

Background: Posterior shoulder tightness, as demonstrated by limited internal rotation range of motion, is a suggested factor in many shoulder pathologies. Methods to increase posterior shoulder mobility may be beneficial. Hypothesis: Shoulder internal rotation range of motion will not change with either of 2 interventions: cross-body stretch alone and cross-body stretch plus posterior capsule joint mobilization. Study Design: Randomized controlled single-blinded clinical trial. Methods: The study comprised 39 college-age asymptomatic participants (7 men, 32 women) who were randomly assigned to 1 of 2 groups: stretching only (n, 20) and stretching plus posterior joint mobilizations (n, 19). All had a between-shoulder difference of internal rotation of 10° or more. Shoulder internal and external rotation was measured before and after a 4-week intervention period and 4 weeks postintervention. Participants in the stretching-only group performed the cross-body stretch on the limited side. Those in the other group (cross-body stretch plus joint mobilization) were treated with posterior joint mobilization techniques on the limited side. Results: Overall means for internal rotation of the treated shoulders significantly increased over baseline at the end of the intervention period and at 4 weeks postintervention. External rotation in all shoulders remained unchanged. By the end of intervention, total motion increased significantly from baseline but decreased significantly from the end of intervention to 4 weeks postintervention. Although not statistically significant, the second group (cross-body stretch plus joint mobilization) had greater increases in internal rotation. At 4 weeks postintervention, the second group had maintained its internal rotation gains to a greater degree than those of the stretching-only group. Conclusion: Internal rotation increased in both groups. Inclusion of joint mobilization in a rehabilitation program created trends toward increased shoulder internal rotation mobility. Clinical Relevance: Both methods—cross-body stretch and cross-body stretch plus joint mobilization—may be beneficial for those with limited internal rotation range of motion.

Context:Alterations in posture and motion patterns are thought to play a role in developing shoulder injuries in overhead athletes. Taping is widely used in the sporting population, but there are limited empirical data regarding its effectiveness.Objectives:To determine and compare the effects of rigid and kinesio taping on shoulder rotation motions, posterior shoulder tightness (PST), and posture in overhead athletes.Design:Randomized controlled trial.Setting:Athletic training rooms.Participants:Eighty-six asymptomatic elite overhead athletes.Interventions:Participants were randomly divided into 4 groups: rigid taping group (RTG) that underwent therapeutic rigid taping, kinesio taping group (KTG) that underwent therapeutic kinesio taping, placebo group that underwent placebo kinesio taping (shoulder and scapular region taping for taping groups), and control group (no taping).Main Outcome Measures:Shoulder rotation motions, PST, and head and shoulder posture were evaluated at baseline, immediately after application and 60 to 72 hours after application for all groups.Results:Glenohumeral internal rotation increased immediately (P < .001) and at 60 to 72 hours after application in the KTG (P = .01), whereas it decreased immediately after application in the RTG (P < .001). Immediately after application, total rotation range of motion increased in the KTG (P =.02) and decreased in the RTG (P < .001), and there was a difference between groups (P = .02). Immediately after application, PST increased in the RTG (P < .001); after 60 to 72 hours, it decreased in the KTG (P = .04) and increased in the RTG (P = .01). Posture outcomes did not change significantly (P > .05).Conclusions:Kinesio taping may improve and rigid taping may worsen glenohumeral internal rotation and PST in overhead athletes. For increasing total rotation range of motion, kinesio taping is superior to rigid taping. Taping did not affect posture. Short-term kinesio taping in overhead athletes may be useful to improve glenohumeral internal rotation, total rotation range of motion, and PST.

BACKGROUND: Posterior shoulder tightness as demonstrated by glenohumeral internal rotation deficit (GIRD) is a common contributor to many shoulder pathologies in overhead throwing athletes. PURPOSE: This study aimed to assess immediate effect of combining glenohumeral and scapulothoracic mobilization with stretching on improving internal rotation range of motion (ROM) in overhead athletes with GIRD METHODS: This study was a single-blind randomized controlled trial with parallel groups. The participants were 30 asymptomatic male volleyball players who had a loss of shoulder internal rotation ROM of 15 degrees or more on their dominant compared to their nondominant side. They were randomly assigned to 1 of 2 groups: stretching only (n = 15) or stretching plus joint mobilization (n = 15). Participants in the stretching group performed cross-body stretches, and those in stretching plus mobilization group were treated with both cross-body stretching and mobilization techniques for the glenohumeral and scapulothoracic joints. Both groups received the intervention every other day for 1 week. Shoulder internal and external ROM were measured before and after the intervention. RESULTS: Before the intervention, dominant-side deficits in internal rotation ROM compared to the nondominant side were 20.11±5.27 degrees in the stretching group and 21.87±8.06 degrees in the stretching plus mobilization group. After the intervention, internal rotation ROM deficit between the dominant and nondominant side decreased to 11.28±5.82 in the stretching group (P <  0.001) and 10.85±9.19 in the stretching plus mobilization group (P <  0.001). However, the between-group difference was not statistically significant (P = 0.389). External rotation ROM remained unchanged in both groups (P >  0.05). CONCLUSION: Both interventions (stretching and stretching plus mobilization) can have the same beneficial effect in decreasing GIRD in asymptomatic overhead athletes.

Throwing Motion

Context:Posterior shoulder tightness has been associated with altered shoulder range of motion (ROM) and several pathologic entities in baseball players. This tightness is hypothesized to be the result of the cumulative stress placed on the posterior shoulder during the deceleration phase of the throwing motion. The role of the posterior shoulder static restraints is to absorb this load while the glenohumeral (GH) external rotators eccentrically decelerate the arm after ball release and therefore also help dissipate this force. As such, the authors hypothesized that if the GH external rotators are weak, an excessive amount of this deceleration force is placed on the static restraints, which may lead to subsequent tightness.Objective:To compare the relationship between GH external-rotation strength and posterior shoulder tightness as measured by GH horizontal-adduction and internal-rotation ROM.Design:Descriptive study.Setting:Laboratory.Participants:45 professional baseball players.Main Outcome Measures:GH external-rotation strength and GH horizontal-adduction and internalrotation ROM.Results:GH external-rotation strength showed no relationship with either GH horizontal-adduction ROM (r2 = .02, P = .40) or GH internal-rotation ROM (r2 = .002, P = .77).Conclusion:There is little to no relationship between GH external-rotation strength and posterior shoulder tightness in professional baseball players. The posterior static restraints of the shoulder may absorb a large majority of the deceleration forces during the throwing motion. Although strengthening of the posterior shoulder dynamic restraints should not be overlooked, routine stretching of the static restraints may be more beneficial for decreasing posterior shoulder tightness and the subsequent risks associated with this tightness, although future research is warranted.

Background: Due to high training volume, competitive swimmers incur shoulder pain and injury1, but certain physical characteristics, such as shoulder ROM and endurance, and tissue adaptations such as posterior capsule thickness (PCT) and supraspinatus tendon structure may also be risk factors. Decreased endurance and ROM have been found in competitive swimmers along with being related to pain2. However, no longitudinal studies have examined pain and disability, range of motion, training volume, shoulder endurance and tendon structure over the course of a competitive season. Purpose: The purpose of this study was to: 1) to assess shoulder pain and disability, internal rotation (IR) and external rotation (ER) and horizontal adduction (HADD) ROM, and posterior shoulder endurance longitudinally over a competitive collegiate season, and 2) determine if there is a relationship between swimming yardage, supraspinatus tendon organization and posterior capsule thickness. Methods: 17 male and 13 female Division III swimmers aged 19.6 ± 1.1 years participated. Pain and disability were assessed using the Penn Shoulder Score and the Disability of Arm Shoulder Hand sports module. Internal rotation (IR), external rotation (ER), and horizontal adduction (HA) were measured using a digital inclinometer. Shoulder endurance was measured using the Posterior Shoulder Endurance Test (PSET). Anterior, center, and posterior supraspinatus tendon images were collected by locating the anterior aspect of the tendon insertion and moving posteriorly. The ultrasound images were analyzed using custom MATlab software to quantify tissue organization. All measures were found in the beginning (T1), middle (T2), and end (T3) of the season. Repeated measure ANOVAs were used to compare longitudinal changes across time.  If p-values were found to be ≤ 0.05, follow-up paired t-tests with Bonferroni corrections were used to compare T1, T2, and T3. This protocol was IRB-approved and participants signed a written consent form. Results: An increase in swimming yardage from T1 to T2 was followed by a significant decrease in yardage to finish the swimming season (Table 1). Disability decreased and endurance increased throughout the season with no observed changes in pain. IR and HA ROM decreased significantly between all timepoint comparisons. Tendon banding frequency did not change over time (Table 2). Discussion: Large amounts of IR during the pull phase and late initiation of ER during the recovery phase have been associated with a high risk of impingement4. The relationship between pain, disability, and range of motion may suggest that a reduction of IR could protect the swimmers’ shoulder by limiting impingement through the pull and recovery phases. However, further investigation is required to confirm. The lack of statistical significance longitudinally in tendon organization is not surprising since there were no changes in pain, a decrease in disability, and an increase in endurance. Conclusion/Clinical Relevance: Further research is required to understand the relationship between training volume, tendon organization, and disability. Collegiate swimmers demonstrate increased endurance and decreased disability over the course of the season. It may suggest that the loss of ROM is a positive adaptation and may be protective.

Hip Replacements

The calculation of range of motion (ROM) is a key factor during preoperative planning of total hip replacements (THR), to reduce the risk of impingement and dislocation of the artificial hip joint. To support the preoperative assessment of THR, a magnetic resonance imaging (MRI)-based computational framework was generated; this enabled the estimation of patient-specific ROM and type of impingement (bone-to-bone, implant-to-bone, and implant-to-implant) postoperatively, using a three-dimensional computer-aided design (CAD) to visualize typical clinical joint movements. Hence, patient-specific CAD models from 19 patients were generated from MRI scans and a conventional total hip system (Bicontact® hip stem and Plasmacup® SC acetabular cup with a ceramic-on-ceramic bearing) was implanted virtually. As a verification of the framework, the ROM was compared between preoperatively planned and the postoperatively reconstructed situations; this was derived based on postoperative radiographs (n = 6 patients) during different clinically relevant movements. The data analysis revealed there was no significant difference between preoperatively planned and postoperatively reconstructed ROM (∆ROM) of maximum flexion (∆ROM = 0°, p = 0.854) and internal rotation (∆ROM = 1.8°, p = 0.917). Contrarily, minor differences were observed for the ROM during maximum external rotation (∆ROM = 9°, p = 0.046). Impingement, of all three types, was in good agreement with the preoperatively planned and postoperatively reconstructed scenarios during all movements. The calculated ROM reached physiological levels during flexion and internal rotation movement; however, it exceeded physiological levels during external rotation. Patients, where implant-to-implant impingement was detected, reached higher ROMs than patients with bone-to-bone impingement. The proposed framework provides the capability to predict postoperative ROM of THRs.
