Utilizing Scapula Retraction Exercises With or Without Glenohumeral Rotational Exercises With a Gradual Progression for Subacromial Pain Syndrome.

BACKGROUND: Although exercise interventions are recommended in the management of subacromial pain syndrome (SPS), there is a lack of data regarding the exercises focusing on the principal biomechanical deficiencies that cause symptoms. HYPOTHESIS: Utilizing progressive scapula retraction exercises (SRE) and glenohumeral rotation exercises (GRE) in the scapula stabilization program may lead to more reduction in symptoms and greater acromiohumeral distance (AHD) values. STUDY DESIGN: A double-blind, randomized controlled trial. LEVEL OF EVIDENCE: Level 2. METHODS: A total of 33 patients were assigned randomly to either SRE or SRE+GRE. Both groups received a 12-week supervised rehabilitation program, including manual therapy and exercises (stretching and progressive scapula stabilization exercises). In addition, the SRE+GRE group performed GRE exercises at gradual elevation angles. From 12 to 24 weeks, patients performed exercise programs less frequently (3 times per week). Disability (shoulder pain and disability index [SPADI]), AHD (at 5 active abduction angles), pain intensity (visual analogue scale [VAS]), and patient satisfaction were recorded at baseline, 12 weeks, and 24 weeks. A total of 16 healthy individuals were recruited as a control group to compare AHD values. Data were analyzed using mixed model analyses of variance. RESULTS: A statistically significant group-by-time interaction was found for AHD values (F4,92 = 6.38; P = 0.001), a significant group-by-time interaction for SPADI-disability (F1,33 = 5.148; P = 0.01), SPADI-total (F1,32 = 4.172; P = 0.03), and for pain during activity (F2,62 = 3.204; P = 0.05). However, no significant group-by-time interaction for SPADI-pain (F1,33 = 0.533; P = 0.48), for pain at rest (F1,31 < 0.001; P = 0.99), and at night (F1,32 = 2.166; P = 0.15). Yet, a significant time effect was observed. CONCLUSION: Progressive SRE and GRE in the scapula stabilization program lessens symptoms and improves AHD values in patients with SPS. Moreover, this program could preserve outcomes and further increase AHD when applied less frequently. CLINICAL RELEVANCE: Utilizing SRE and GRE in the scapula stabilization program at gradual shoulder abduction angles provides better rehabilitation outcomes.

Effects of Different Frequencies of Physical Therapy Visits on Shoulder Function After Arthroscopic Rotator Cuff Repair.

OBJECTIVE: There is no consensus about the optimal frequency of patient visits during the rehabilitation program after arthroscopic rotator cuff repair (ARCR). This study aimed to investigate the short- and long-term effects of high-frequency (HF) and low-frequency (LF) visits of the patients in the first 12 weeks of rehabilitation after ARCR. METHODS: This was a quasi-randomized study with 2 parallel groups. Forty-seven patients with ARCR were included in 2 different patient visit frequency protocols (HF = 23, LF = 24) in 12 weeks of postoperative rehabilitation. Patients in the HF group visited the clinic twice a week, whereas patients in the LF group visited once every 2 weeks for the first 6 weeks and once a week for the following 6 weeks. Both groups performed the same exercise protocol. Outcome measurements were pain and range of motion measured at baseline; at the 3rd, 5th, 8th, 12th, and 24th weeks; and at 1-year follow-up. Shoulder function was assessed at the 12th and 24th weeks and at 1-year follow-up with an American Shoulder and Elbow Surgeons score. RESULTS: There was a significant group × time interaction in pain intensity during the activity between the groups. The activity pain intensity was higher in the LF group (4.2 points) at 8 weeks post surgery than in the HF group (2.7 points) (mean difference: 1.5 points, P < .05), whereas it was similar in both groups at other time periods. The interaction term was not significant between the groups for pain intensity during rest and night through the 1-year follow-up. No group × time interactions were observed in shoulder range of motion and American Shoulder and Elbow Surgeons score over the postoperative period. CONCLUSION: Both rehabilitation programs at different visit frequencies after ARCR showed similar clinical results in the long term. A supervised, controlled rehabilitation program with LF visits in the first 12 weeks after surgery can be sufficient to achieve optimal clinical results and reduce rehabilitation-related costs after ARCR. IMPACT: This study highlights that LF treatment protocols under the supervision of the therapist can be adopted after the arthroscopic rotator cuff repair to achieve successful results while decreasing the treatment costs. Physical therapists should plan the treatment sessions efficiently for the compliance of the patients to the exercise treatment. LAY SUMMARY: If you are a patient with arthroscopic rotator cuff repair, a supervised, controlled rehabilitation program with low-frequency visits in the first 12 weeks after surgery could help you achieve the best outcome and help lower the costs of rehabilitation. A total of 3 visits in the first 6 weeks might be sufficient (once every 2 weeks). More frequent visits (1-2 visits a week) should happen 6 to 12 weeks after the surgery.

Recovery of the shoulder kinematics after reverse shoulder arthroplasty.

BACKGROUND: There is very limited information about the changes in shoulder kinematics in patients with reverse shoulder arthroplasty. The aim of the study was to investigate the changes in the scapulohumeral rhythm and shoulder kinematics over time after the reverse shoulder procedure. METHODS: Nineteen patients with reverse shoulder arthroplasty (age: 65.8 ± 10.3 years) were included to the study. During arm elevation in the sagittal and scapular planes, operated shoulder kinematics (humerothoracic elevation, glenohumeral elevation, scapulohumeral rhythm, and scapular rotations) were assessed using an electromagnetic tracking system at the postoperative 3rd, 6th, and 18th months. Asymptomatic shoulder kinematics were also assessed at the postoperative 18th month. Shoulder function was assessed using The Disabilities of the Arm Shoulder and Hand score at the postoperative 3rd, 6th, and 18th months. FINDINGS: Maximum humerothoracic elevation increased from 98° to 109° over the postoperative period (p = 0.01). The scapulohumeral rhythm was similar on the operated and asymptomatic shoulders at the final follow-up (p = 0.11). Both the operated and asymptomatic shoulder demonstrated similar scapular kinematics at the postoperative 18th month (p > 0.05). The Disabilities of the Arm Shoulder and Hand score decreased over time in the postoperative period (p < 0.05). INTERPRETATION: Shoulder kinematics may be improved after reverse shoulder arthroplasty in the postoperative period. Focusing on scapular stabilization and deltoid muscle control in the postoperative rehabilitation program may enhance the shoulder kinematics and upper extremity function.

Effectiveness of Kinesio Taping and Night Splinting Along With Physical Therapy Intervention on Symptoms and Functionality: A Double-Blind Randomized Controlled Trial for Moderate Carpal Tunnel Syndrome.

OBJECTIVE: The aim of the study is to compare the effects of Kinesio taping and night splinting along with physical therapy intervention on symptoms in patients with moderate carpal tunnel syndrome undergoing rehabilitation. DESIGN: In this double-blind, randomized controlled trial, 45 patients with moderate carpal tunnel syndrome were included and randomly assigned to three groups: Kinesio taping group ( n = 15), night splinting group ( n = 15), and control group ( n = 15). All patients received 20 physical therapy intervention sessions. The primary outcome was self-reported disability status measured by the Boston Carpal Tunnel Questionnaire, and secondary outcomes were pain and paresthesia (rest, activity, and night) measured by the Numeric Rating Scale. Outcomes were recorded at baseline and 4 wks. RESULTS: All patients showed clinically meaningful improvements for all outcome measures over time ( P < 0.05). The intergroup analysis revealed that the Kinesio taping group demonstrated better results in all measures than the night splinting ( P < 0.05) except for pain during activity ( P = 0.054), at night ( P = 0.191), and paresthesia at rest ( P = 0.575). In addition, the Kinesio taping group showed better outcomes than the control group ( P < 0.05) except for the activity pain ( P = 0.022). However, there were negligible differences between night splinting and control group ( P > 0.05). CONCLUSION: Kinesio taping in combination with physical therapy intervention is more effective than night splinting in combination with physical therapy intervention or physical therapy intervention alone and may be recommended.

Acromiohumeral distance quantification during a variety of shoulder external and internal rotational exercises in recreationally overhead athletes.

To determine whether shoulder external (ER) and internal rotational (IR) exercises at five different shoulder abduction angles affect the acromiohumeral distance (AHD). Twenty recreational overhead athletes were included. AHD was measured using real-time ultrasound for each of the five shoulder conditions as follows: neutral shoulder rotation (active-hold) and during ER and IR exercises (isometric and concentric) at five different shoulder-abduction angles (0°, 30°, 45°, 60°, and 90° of abduction). A two-way ANOVA was used to analyze AHD values. Shoulder abduction angle × exercise interaction for AHD was found (F16,304 = 10.92; p < .001; η2 = 0.37). For both isometric and concentric conditions, AHD increased during IR exercises (p < .05) yet decreased during ER exercises (p < .05) when compared with each active-hold positions. Shoulder ER and IR exercises influence the AHD in recreational overhead athletes. A larger AHD was observed during shoulder IR exercises, whereas ER exercises failed to maintain the AHD.

Translation, cross-cultural adaptation, and validation of the Turkish version of the shoulder instability-return to sport (SI-RSI) after injury scale.

To translate and culturally adapt the shoulder instability-return to sport after injury (SI-RSI) scale into Turkish (SI-RSI-Tr) and examine the psychometric properties of the Turkish version of athletes following a traumatic shoulder instability. The SI-RSI was translated into Turkish using Beaton guidelines. Sixty-nine patients with shoulder instability completed the translated SI-RSI, Western Ontario Shoulder Instability Index (WOSI), the Tampa Scale of Kinesiophobia (TSK), and the Walch-Duplay Scores. We analysed the internal consistency, agreement, reliability, and validity of the SI-RSI-Tr. The SI-RSI-Tr demonstrated excellent internal consistency (Cronbach's alpha = 0.92), test-retest reliability (ICC = 0.95), and feasibility with no ceiling or floor effect. SI-RSI-Tr correlated with WOSI total score (r = -0.824, p < 0.001), its subscales: WOSI-physical (r = -0.683, p < 0.001), WOSI-sports (r = -0.832, p < 0.001), WOSI-lifestyle (r = -0.739, p < 0.001), and WOSI-emotions (r = -0.734, p < 0.001) respectively), Walch-Duplay (r = 0.840, p < 0.001) and TSK (r = -0.828, p < 0.001) scores. The Turkish SI-RSI is a reliable, internally consistent, and valid tool for athletes with shoulder instability. Researchers and clinicians could safely use the SIRSI-Tr to evaluate the shoulder-specific psychological factors on return to sports following an episode of shoulder instability.

Tender point examination with palpation in different shoulder pathologies: A retrospective study.

BACKGROUND: Shoulder pain is a common symptom for non-traumatic shoulder pathologies and affects 4.7-66.7% of entire population. Even with the latest technological advantages, palpation still is a cost and time efficient tool to evaluate the shoulder pathologies. Our aim was to investigate and compare palpation findings in different shoulder pathologies. METHOD: We used first assessments of impingement syndrome (IS) (n = 205), rotator cuff tear (RCT) (n = 185) and frozen shoulder (FS) (n = 210) patients who received treatment between 2010 and 2019 years. Two experienced physiotherapists palpated predefined points: long head of biceps brachii, pectoralis minor, lateral intermuscular septum, proximal tendons of extensor group. These points categorized into "proximal", "mid-proximal", "mid-distal", "distal", "irregular". We also grouped patients by their BMIs. RESULTS: We found RCT patients had higher BMI than IS and FS patients (p < 0.001, p = 0.001); more tender intermuscular septum points and night pain than IS patients (p = 0.001, p = 0.003) and more extensor group proximal tendon points than IS and FS patients (p < 0.001, p = 0.001). "No tenderness" group had lesser resting pain than distal group (p < 0.001) and lesser activity and night pain than middle-proximal, middle-distal, and distal groups (all ps < 0.002). Distal group had higher night pain than middle-proximal group (p = 0.003). Morbidly obese patients had higher night pain than normal and overweight patients (p = 0.003 and p = 0.009). CONCLUSIONS: Tender point distribution varies depending on the pathology with biceps brachii being the most common. RCT patients had higher night pain related to more distal tender points. Patients with higher night pain had increased tenderness in septum intermuscular and extensor muscles' proximal tendons.

Effect of Plyometric Training on Sport Performance in Adolescent Overhead Athletes: A Systematic Review.

CONTEXT: Plyometric training has been shown to be beneficial in adolescent overhead athletes. However, existing research on the effects of plyometrics on sport performance has been limited. OBJECTIVE: To systematically review the current literature to investigate whether plyometric training intervention improves upper- and lower-body sport performance. DATA SOURCES: Two electronic databases (MEDLINE and Web of Science) were searched using specific Medical Subject Headings (MeSH) terms up to February 2019, and hand-searching was performed by looking to relevant studies that were cited in other studies. STUDY SELECTION: A total of 932 items were identified and were further assessed for the eligibility in the systematic review. For a study to be eligible, each of the following inclusion criteria had to be met: (1) participants were aged 13 to 18 years and selected from a sports or athletic population and the study (2) involved the evaluation of a plyometric training intervention with an aim to improve sports performance; (3) must have included a control intervention and/or control group; (4) included a quantitative objective measure of sport performance variables concerning throwing, jumping, running, and sprinting; and (5) was published in English. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 3. DATA EXTRACTION: A first screening was conducted based on title and abstract of the articles. In the second screening, the full text of the remaining articles was evaluated for the fulfillment of the inclusion criteria. RESULTS: A total of 14 studies were included in this review. The methodological quality of the included studies ranged from low to moderate. There is moderate evidence that plyometric training intervention improves throwing and jumping performances. There is also preliminary evidence that plyometric training intervention improves sprint performance. CONCLUSION: The current evidence suggests that sport performance consisting of throwing capacity, jumping ability, and sprint performance significantly improved due to plyometric training interventions in adolescent overhead athletes.

The repeatability of 3-dimensional scapular kinematic analysis during bilateral upper extremity movements.

Although three-dimensional electromagnetic systems are widely used to evaluate the 3-dimensional scapular kinematics their reliability when testing bilateral upper extremity tasks is unknown. The purpose of this study was to investigate the repeatability of the scapular kinematic analyses using the Flock of Birds (FOB) system during bilateral upper extremity movements. Twenty-one volunteers without shoulder problems were included (aged 24.8 years; body mass index averaged 21.2 kg/m2) to the study. Scapular internal-external rotation, upward-downward rotation, and anterior-posterior tilt was recorded during bilateral arm elevation on sagittal, scapular and frontal planes. Measurements were repeated at 5-7 days intervals. Intra-session and inter-session repeatability were determined using intraclass correlation coefficients (ICC) scores and standard errors of measurements (SEM). The ICC scores were found to be 0.81 to 0.99 for intra-session measurements and 0.60 to 0.83 for inter-session measurements. The SEM scores were 0.8°-3.4° and 2°-7.2° for the intra and inter-session measurements respectively. The repeatability of the FOB system was excellent for the intra-session measurements, but it was weaker for the inter-session measurements. These results support the use of the FOB system for assessing scapular orientation but the analyses should be conducted more carefully when it is applied to the longitudinal measurements.

Which method for frozen shoulder mobilization: manual posterior capsule stretching or scapular mobilization?

OBJECTIVES: This study aimed to compare the superiority of scapular mobilization, manual capsule stretching, and the combination of these two techniques in the treatment of frozen shoulder patients to evaluate the acute effects of these techniques on shoulder movements. METHODS: This study designed to a single-blinded, randomized, and pre-post assessment study. This study was included 54 patients diagnosed with stage 3 frozen shoulder. Group 1 (n=27) received scapular mobilization, and Group 2 (n=27) received manual posterior capsule stretching. After the patients were assessed, the interventions were re-applied with a crossover design to obtain results for the combined application (n=54). The range of motion, active total elevation, active internal rotation, and posterior capsule tensions of the shoulder joint were recorded before and immediately after mobilization. RESULTS: Statistical analysis showed an increase in all range of motion values (p<0.05), except for shoulder internal rotation (p>0.05), without significant difference among the groups (p>0.05). The posterior capsule flexibility did not change in any group (p>0.05). CONCLUSIONS: Scapular mobilization and manual posterior capsule interventions were effective in improving the acute joint range of motion in frozen shoulder patients.

Cross-education improves quadriceps strength recovery after ACL reconstruction: a randomized controlled trial.

PURPOSE: The aim of this study was to investigate the effects of concentric and eccentric cross-education (CE) on quadriceps strength and knee function recoveries after anterior cruciate ligament (ACL) reconstruction. METHODS: Forty-eight patients (age: 29.5 ± 6.8 years, body mass index: 26.1 ± 3.2 kg/m2) who had undergone ACL reconstruction with hamstring tendon autograft were included in the study. The patients were randomly divided into three groups when they reached four weeks post surgery: (1) concentric CE (n = 16); (2) eccentric CE (n = 16); and (3) control (n = 16). All groups followed the same post-surgical rehabilitation program for their reconstructed limb. Additionally, the two experimental groups followed eight weeks of isokinetic training for the uninjured knee at 60°/s for 3 days per week. Quadriceps maximum voluntary isometric strength (MVIC) was measured during the 4th week (pre-training), 12th week (post training), and 24th week post surgery. The single-leg hop distance and International Knee Documentary Committee (IKDC) scores were also evaluated during the 24th week post surgery. Analysis of variance was used for statistical analysis. RESULTS: Group-by-time interaction was significant for quadriceps MVICs for reconstructed and healthy limbs (p = 0.02). Quadriceps strength of both knees was greater in concentric and eccentric CE groups compared to control group during the 12th- and 24th weeks post surgery (p < 0.05). Strength gain was 28% and 31% in concentric and eccentric CE groups, respectively, when compared with the control group. Concentric and eccentric CE had similar effects on quadriceps strength recovery (n.s.). IKDC score, and single-leg hop distances were not significantly different among groups (n.s.). CONCLUSIONS: Concentric and eccentric quadricep strengthening of healthy limbs in early phases of ACL rehabilitation improved post-surgical quadriceps strength recovery of the reconstructed limb. CE should be integrated into ACL reconstruction rehabilitation, especially in the early rehabilitative phases to restore quadriceps strength. LEVEL OF EVIDENCE: Randomized controlled trial, Level I.

A three-dimensional scapular motion analysis in patients with arthroscopic anterior capsulolabral repair of the shoulder: The effect of scapular stabilization taping.

BACKGROUND: The aim of this study was to investigate the scapular kinematics during dynamic humeral movements in patients with arthroscopic anterior capsulolabral repair of the shoulder along with the potential biomechanical corrective effects of scapular stabilization taping. METHODS: Twenty patients with unilateral traumatic anterior shoulder instability and arthroscopic anterior capsulolabral repair participated in the study. Dynamic shoulder kinematics were assessed during the scapular plane shoulder elevation for both the operated and non operated shoulders and also under two conditions: no-taping and taping. Statistical analysis to compare sides and conditions was performed with analysis of variance models. RESULTS: The scapula was more internally rotated position in operated shoulders than in non operated shoulders. Furthermore, the scapula was less internally rotated and more downwardly rotated at 120° of elevation in the taping condition. CONCLUSIONS: Operated shoulders demonstrated kinematics alterations when compared to non operated shoulders underwent arthroscopic anterior capsulolabral repair. Additionally, changes in the scapular orientation with the taping was very small but followed a pattern, which would be suggested to be an orientation that potentially produce more scapular stability and to increase stress on the inferior glenohumeral ligament.

Does Kinesiotaping improve pain and functionality in patients with newly diagnosed lateral epicondylitis?

PURPOSE: This study aimed to compare the short-term effects of kinesiotaping and extracorporeal shock wave therapy (ESWT) along with physiotherapy on pain, functionality, and grip strength in patients with newly diagnosed lateral epicondylitis undergoing rehabilitation. METHODS: Forty-five voluntary patients (mean age 48 years) were randomly assigned to three groups. Patients in all groups received physiotherapy consisting of a cold pack and transcutaneous electrical nerve stimulation five times per week for a total of 15 sessions and a home exercise programme including stretching and eccentric strength exercises. In the second group, patients received kinesiotaping 5 days a week for 3 weeks. In the third group, ESWT was applied three times for 3 weeks. Patients were assessed by visual analogue scale for pain intensity, pain-free grip strength using a hand dynamometer, Cyriax Resisted Muscle Test, and Patient-Rated Tennis Elbow Evaluation Scale. All measurements were collected at baseline and after treatment. RESULTS: There were no significant differences in the demographic characteristics of the patients in all groups at baseline. Intra-group analysis revealed that pain intensity decreased, whereas maximum grip strength and functionality increased in all groups at the end of the treatment (p < 0.05). Inter-group analysis revealed that the kinesiotaping group yielded better results in decreasing pain intensity than the other groups (p < 0.05). The kinesiotaping group (p < 0.001) and ESWT group (p = 0.002) yielded better results in improving functionality than the physiotherapy group. There were significant differences in recovering pain-free grip strength in the kinesiotaping group (p < 0.05). CONCLUSION: Kinesiotaping was found to be effective for decreasing pain intensity, recovering grip strength, and improving functionality in patients with lateral epicondylitis undergoing rehabilitation. LEVEL OF EVIDENCE: Therapeutic study, Level II.

Shoulder kinematics and mobility adaptations in water-polo players.

BACKGROUND: There is limited research to demonstrate how scapular kinematics and shoulder-related physical characteristics are affected in water-polo players, who undertake swimming and repetitive throwing activity. The aim of this study was to investigate possible adaptations in the three-dimensional scapular kinematics and in glenohumeral internal rotation, external rotation range of motion and shoulder posterior-capsule tightness in water-polo players. METHODS: Fourteen water-polo players and 14 asymptomatic volunteers participated in the study. The scapular kinematics were recorded using an electromagnetic tracking device during the scapular plane shoulder elevation. Additionally, shoulder range of motion and posterior-capsule tightness were evaluated. Analysis of variance models were used to make comparisons between groups. RESULTS: Although there was a trend toward increased scapular internal rotation and downward rotation in the throwing shoulders of water-polo players, comparisons revealed there was no significant differences in kinematics, shoulder internal-external range of motion and posterior-capsule tightness between the throwing shoulders of the players and dominant shoulders of the control participants. CONCLUSIONS: The throwing shoulders of water-polo players did not demonstrate alterations in shoulder kinematics and mobility parameters.

Translation and cross-cultural adaptation of the anterior cruciate ligament-return to sport after injury (ACL-RSI) scale into Turkish.

PURPOSE: To translate and culturally adapt the anterior cruciate ligament-return to sport after injury (ACL-RSI) scale into Turkish (ACL-RSI-Tr) and examine and evaluate the psychometric properties of the Turkish version in individuals who have undergone anterior cruciate ligament (ACL) reconstruction. METHODS: The ACL-RSI was forward- and back-translated, culturally adapted and validated on ninety-three Turkish individuals who had undergone ACL reconstruction (5 females, 88 males; age 28.7 ± 8.6 years; body mass 80.1 ± 13.9 kg; height 178.8 ± 6.9 cm; body mass index 25.0 ± 3.7 kg/m2). All patients completed the translated ACL-RSI, Tampa Scale of Kinesiophobia (TSK), Knee injury and Osteoarthritis Outcome Score (KOOS) and International Knee Documentary Committee (IKDC) and Lysholm questionnaires. We then analysed the internal consistency, reliability and validity of the newly formed ACL-RSI-Tr scale. RESULTS: The ACL-RSI-Tr showed good internal consistency (Cronbach's alpha 0.86) and test-retest reliability (ICC 0.92) and was significantly correlated with the KOOS 'quality of life' (r = 0.58, p < 0.002), 'symptoms and stiffness' (r = 0.35, p = 0.001), 'pain' (r = 0.49, p < 0.001), 'sports' (r = 0.44, p < 0.001) and 'daily life' (r = 0.42, p < 0.001) subscales. The ACL-RSI-Tr also correlated significantly with the TSK (r = - 0.45, p < 0.001), Lysholm (r = 0.45, p < 0.001) and IKDC (r = 0.44, p < 0.001) scores. CONCLUSIONS: The Turkish version of the ACL-RSI scale was valid, discriminant, consistent and reliable in patients who had undergone ACL reconstruction. This score could be useful to evaluate the effect of psychological factors on return to sport following ACL surgery. LEVEL OF EVIDENCE: Diagnostic study, Level I.
