Short-Term Effects of Cold Therapy and Kinesio Taping on Pain Relief and Upper Extremity Functionality in Individuals with Rotator Cuff Tendonitis: A Randomized Study. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:1188. [PMID: 39202470 PMCID: PMC11356310 DOI: 10.3390/medicina60081188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/06/2024] [Revised: 06/24/2024] [Accepted: 07/17/2024] [Indexed: 09/03/2024]
Abstract
Background and Objectives: Rotator cuff tendonitis (RCT) is one of the most common shoulder pathologies. It causes pain, limits shoulder joint movements, and impairs function. Despite various treatment methods, there are currently no specific guidelines regarding the most effective intervention for RCT. To the best of our knowledge, no studies have compared the effects of Kinesio taping (KT) and cold therapy (CT) on individuals with RCT. To this end, this study aimed to investigate and compare the short-term effects of KT and CT on pain relief and upper extremity functionality in individuals with RCT. Materials and Methods: One hundred and fourteen individuals were assessed for eligibility. Fifty-two individuals with RCT who met the inclusion criteria and agreed to participate were randomly allocated into either the KT or the CT group. A standardized home exercise program was given to all the participants. Their pain intensity, upper extremity function, shoulder range of motion (ROM), and grip strength were evaluated initially and after the three days of KT or CT applications. Results: All the assessment values significantly improved in the KT group. In the CT group, only the pain scores (except for the numerical rating scale (NRS) pain score during activity) were significantly improved in the CT group at the end of the third day of application compared to the initial values (p < 0.05). For all the measurement outcomes, the effects of time × group interactions were statistically significant (p < 0.05) in favor of the KT group, except for the resting pain (p = 0.688). Conclusions: The findings suggest that KT and CT could be used as adjunctive modalities to exercise for resting and night pain relief in patients with RCT. KT also had positive effects on the activity pain, function, ROM, and grip strength. The use of KT along with an exercise program could be a more effective therapeutic choice than the use of CT for improving night pain, activity pain, and upper extremity function during the short-term rehabilitation of RCT patients.

Preoperative handgrip strength can predict early postoperative shoulder function in patients undergoing arthroscopic rotator cuff repair. J Orthop Surg Res 2024; 19:270. [PMID: 38689328 PMCID: PMC11059705 DOI: 10.1186/s13018-024-04750-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 04/19/2024] [Indexed: 05/02/2024] Open
Abstract
BACKGROUND Rotator cuff tears (RCTs) are a common musculoskeletal disorder, and arthroscopic rotator cuff repair (ARCR) is widely performed for tendon repair. Handgrip strength correlates with rotator cuff function; however, whether preoperative grip strength can predict functional outcomes in patients undergoing ARCR remains unknown. This study aimed to investigate the correlation between preoperative grip strength and postoperative shoulder function following ARCR. METHODS A total of 52 patients with full-thickness repairable RCTs were prospectively enrolled. Baseline parameters, namely patient characteristics and intraoperative findings, were included for analysis. Postoperative shoulder functional outcomes were assessed using the Quick Disabilities of the Arm, Shoulder, and Hand (QDASH) questionnaire and Constant-Murley scores (CMSs). Patients were followed up and evaluated at three and six months after ARCR. The effects of baseline parameters on postoperative outcomes were measured using generalized estimating equations. RESULTS At three and six months postoperatively, all clinical outcomes evaluated exhibited significant improvement from baseline following ARCR. Within 6 months postoperatively, higher preoperative grip strength was significantly correlated with higher CMSs (β = 0.470, p = 0.022), whereas increased numbers of total suture anchors were significantly correlated with decreased CMSs (β = - 4.361, p = 0.03). Higher body mass index was significantly correlated with higher postoperative QDASH scores (β = 1.561, p = 0.03) during follow-up. CONCLUSIONS Higher baseline grip strength predicts more favorable postoperative shoulder function following ARCR. A preoperative grip strength test in orthopedic clinics may serve as a predictor for postoperative shoulder functional recovery in patients undergoing ARCR.

Abstract
BACKGROUND Hand injuries are common and could have an impact on all upper limb functions. Engaging shoulder muscle training during the rehabilitation protocol postoperatively could have a significant impact on regaining all upper limb function. The purpose of this study was to assess the effect of adding shoulder stabilization exercise to hand rehabilitation postoperatively. METHODS Forty patients were randomly assigned to 2 equal groups. Group A received a standard physical therapy program plus shoulder exercise protocol and group B received only a standard physical therapy protocol for hand rehabilitation. Outcome measures were pain intensity; grip strength; Arabic modified Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire; and range of motion (ROM). All outcome measures were assessed before and after treatment. RESULTS Statistical analysis revealed that both groups, the experimental and control, showed significant improvement in all outcome measures, but experimental group A showed significant improvement than the control group B posttreatment for hand grip strength, ROM, and QuickDASH questioners (P < .001). CONCLUSION Adding shoulder stabilizer muscle training to the hand rehabilitation protocol postoperatively has a significant impact on hand function outcomes.

J Shoulder Elbow Surg 2023; 32:2430-2435.

Abstract
BACKGROUND Systemic disorders including diabetes mellitus, obesity, and depression affect the outcomes of reverse shoulder arthroplasty (RSA). Sarcopenia (a general skeletal muscle disorder) is common in elderly people, but its effect on patients after RSA is not clear. We hypothesized that the preoperative sarcopenia indices of grip strength and general skeletal muscle mass would correlate with the clinical outcomes of RSA. METHODS Grip strength and general skeletal muscle mass were measured in patients scheduled (between 2016 and 2021) for primary RSA to treat cuff tear arthropathy, an unrepairable cuff tear, or osteoarthritis with a large cuff tear. Before surgery, grip strength was measured using a hydraulic dynamometer and general skeletal muscle mass was calculated from the appendicular relative skeletal muscle mass index (aRSMI) using dual-energy X-ray absorptiometry. In all, 58 patients were included; the minimal follow-up duration was 12 months. The postoperative clinical results (pain, active range of motion, shoulder strength, and functional scores) were evaluated during scheduled outpatient visits. We calculated correlations between the preoperative sarcopenia indices, and the clinical results at the final follow-up. RESULTS The mean preoperative grip strength and aRSMI were 21.6 ± 4.0 kg and 5.98 ± 0.84 kg/m2 in females and 30.6 ± 7.5 kg and 7.21 ± 0.94 kg/m2 in males, respectively; the grip strength and aRSMI were not associated with each other (P = .083). Ten females (25%) and 10 males (56%) met the criteria for sarcopenia. The postoperative abduction shoulder strength and Constant-Murley shoulder score increased significantly with higher preoperative grip strength (R = 0.420 and P = .001; and R = 0.497 and P < .001, respectively) and the American Shoulder and Elbow Surgeons score was related to the preoperative aRSMI (R = 0.320, P = .039). CONCLUSIONS The shoulder strength and functional score after RSA correlated positively with the preoperative grip strength. Measuring grip strength before RSA allows the surgeon to predict shoulder strength after RSA.

Short-Term Effects of Centralization of the Glenohumeral Joint and Dynamic Humeral Centering on Shoulder Pain, Disability, and Grip Strength in Patients with Secondary Subacromial Impingement Syndrome. Healthcare (Basel) 2023; 11:2914. [PMID: 37998406 PMCID: PMC10671653 DOI: 10.3390/healthcare11222914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 10/30/2023] [Accepted: 11/06/2023] [Indexed: 11/25/2023] Open
Abstract
Subacromial impingement syndrome (SIS) is one of the most common causes of shoulder pain in adults and is caused by muscle imbalance around the shoulder joint, which is referred to as secondary SIS. Centralization of the glenohumeral joint (CGH), one of the intervention methods for this, targets strengthening the control ability of the rotator cuff. Dynamic humeral centering (DHC) targets the learning of selective contractile function of the pectoralis major and latissimus dorsi as depressors of the humeral head. This study aims to determine the short-term effects of CGH and DHC on pain, disability, and grip strength in patients with secondary SIS. Forty-eight patients with secondary SIS participated in the study and were randomly allocated into three groups (CGH group (n = 16), DHC group (n = 16), and simple exercise group (n = 16)) and received the intervention for 50 min. The Constant-Murley score was used to assess shoulder pain and disability (primary outcome), and a hand-held dynamometer was used to assess grip strength (secondary outcome). Measurements were performed before the intervention and one day after the intervention. The results showed that the Constant-Murley score improved in the CGH and DHC groups. In addition, pain and disability (range of motion scores) improved in both the CGH and DHC groups. Improvements in disability (shoulder strength) and grip strength were seen only in the CGH group. Both CGH and DHC can be used as methods for short-term pain release and disability recovery in secondary SIS. In particular, CGH appears to be more effective in the short-term improvement in shoulder strength and grip strength.

Abstract
Introduction Digital dynamometers to assess grip strength are becoming more common in research and clinical settings. The aim of the study was to assess validity and reliability of the K-force dynamometer compared to the Jamar dynamometer. We also aimed to assess differences over the course of three measurements. Methods Twenty-seven healthy participants were included. Three trials with the K-force and Jamar dynamometers were completed. Testing order was randomised. Intraclass correlation coefficients (ICCs) with absolute agreement assessed reliability and validity. Standard error of the measurement (SEM) and minimal detectable change (MDC95) were calculated. Concurrent validity was assessed using Pearson's correlations and ICCs. Differences between the three repetitions were assessed using one-way repeated measures ANOVAs. Results Both the K-force and the Jamar presented excellent intra-rater reliability with ICCs ranging from 0.96 to 0.97. The SEM ranged from 1.7 to 2 kg and the MDC from 4.7 to 5.7 kg for both dynamometers. The concurrent validity of the K-force was high (r ≥ 0.89). However, the K-force underestimated the grip strength by 4.5-8.5 kg. There was no change in grip strength with either dynamometer over the course of three trials. Conclusions The K-force is reliable, but it underestimates grip strength by 4.5-8.5 kg compared to the Jamar dynamometer. K-force can be used to monitor progress over time but cannot be used to compare results against normative data. The use of a single measurement when assessing grip strength is sufficient when assessing healthy subjects.

Abstract
INTRODUCTION To date, there is no valid single test or battery of tests for informing return-to-play (RTP) decisions following an acute shoulder injury. The purpose of this exploratory study is to evaluate a diagnostic test battery based on a Delphi consensus at the time of unrestricted return to team training after acute shoulder injury. METHODS AND ANALYSIS Data for this prospective multicentre cohort study are collected at two measurement time points: when the respective physician clears the patient for RTP (t1) and 12 months after RTP (t2). The study participants are 18-35 years old athletes participating at a professional level in the following team sports: handball, basketball, ice hockey, soccer, volleyball and American football. Maximum comparability will be ensured via uninjured matched pair teammates. To assess the subjective assessment of shoulder functioning and the athlete's readiness to RTP, patient-reported outcome measures (Western Ontario Shoulder Instability Index, Quick-Disabilities of the Arm, Shoulder and Hand, Psychological Readiness of Injured Athlete to Return to Sport and Shoulder Instability-Return to Sport after Injury) will be completed. After a medical check-up with a range of motion and anthropometric measurements as well as clinical tests, the participants will perform a structured warm-up protocol. The functional tests comprise handgrip strength, upper quarter Y-balance test, isometric strength, closed kinetic chain upper extremity stability test, wall hop test, functional throwing performance index and the unilateral seated shot put test and isokinetic tests. ETHICS AND DISSEMINATION The results of this study will be disseminated through peer-reviewed publications and scientific presentations at national and international conferences. Ethical approval was obtained through the Institutional Review Board of Martin-Luther-University Halle-Wittenberg (reference number: 2022-016). TRIAL REGISTRATION NUMBER DRKS00028265.

Abstract
Background/Aims Shoulder pain is reported to be the third most common musculoskeletal disorder. Rotator cuff muscles play an important role in stabilising the shoulder and decreasing pain. Assessment of handgrip strength has been proposed as an indicator of rotator cuff function in healthy individuals, but not in those experiencing shoulder pain. The aim of this study was to assess the relationship between handgrip strength and shoulder rotator cuff strength in patients experiencing shoulder pain as a result of pathology or surgical intervention. A secondary aim was to identify any association between the duration of shoulder pain and handgrip strength and shoulder rotator cuff strength. Methods A total of 32 patients with shoulder pain (19 men, 13 women) were evaluated. The mean age was 52.88 (± 15.66) years, with a mean duration of shoulder pain of 13.44 (± 10.22) weeks. Handgrip strength was measured using the standard Jamar hydraulic hand dynamometer, and individual isometric rotator cuff strength was measured using the Baseline push-pull dynamometer. Results Correlation was found between handgrip strength and the abductor (r=0.58), external rotator (r=0.57), and internal rotator strength (r=0.59). A linear regression model was used to derive the equations for the association. No significant (P>0.05) correlation was found between the duration of pain and the handgrip strength or rotator cuff strength. Conclusions The strength of the correlation found indicates that handgrip strength can be used for assessment and within a rehabilitation programme to monitor rotator cuff function in patients with shoulder pain or post-surgical rehabilitation. The strength of rotator cuff muscles can be predicted by the equations derived from the regression model relating to grip strength assessment.

Abstract
Rotator cuff tear is a common cause of shoulder pain and disability. Arthroscopic rotator cuff repair (ARCR) is performed to treat a torn tendon. Postoperative joint immobilization is essential, but it is a problem that needs to be addressed in the rehabilitation process. This study aimed to evaluate the effects of radial extracorporeal shock wave therapy (rESWT) in patients who underwent ARCR and required active movement after the immobilization period. This study was an open-label, prospective, single-arm trial of 30 inpatients aged >18 years who underwent ARCR. A total of 6 rESWT sessions, along with the conventional rehabilitation program for ARCR patients, were provided at the hospital's sports rehabilitation center for 2 weeks. The application sites of rESWT are periscapular muscles (supraspinatus, infraspinatus, teres minor, and rhomboid). Evaluations were conducted 3 time points-baseline, immediately after the first session of rESWT, and after 2 weeks of intervention. The outcome measures were the numeric pain rating scale for pain, and shoulder flexion, scaption flexion, abduction, horizontal adduction, external rotation, and internal rotation for shoulder range of motion. For shoulder function, disabilities of the arm, shoulder and hand, shoulder pain and disability index, and simple shoulder test were used, and muscle strength was expressed by grip strength. supraspinatus and infraspinatus evaluated thickness, tone, and stiffness. The muscle strength (95% CI, -3.554 to -0.073) and supraspinatus tone (P = .017) showed significant changes immediately after the first session of rESWT. Further, there was significant improvement in ROM (P < .01); shoulder function (P < .01); and muscle strength (95% CI, -3.561 to -0.625), supraspinatus stiffness (95% CI, -67.455 to -26.345), and infraspinatus stiffness (P = .045) after 2 weeks of intervention. However, muscle thickness and tone were significantly improved only in supraspinatus (P = .044, P = .040). Rehabilitation with radial extracorporeal shock wave therapy additionally applied to the periscapular muscles in patients who started active movement in rehabilitation after arthroscopic rotator cuff repair is effective for shoulder function and muscle properties (muscle strength, thickness, tone, and stiffness). However, a randomized controlled trial is needed to further assess the effects of radial extracorporeal shock wave therapy alone.

Handgrip Strength Exercises Modulate Shoulder Pain, Function, and Strength of Rotator Cuff Muscles of Patients with Primary Subacromial Impingement Syndrome. BIOMED RESEARCH INTERNATIONAL 2022; 2022:9151831. [PMID: 36082154 PMCID: PMC9448609 DOI: 10.1155/2022/9151831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Revised: 08/11/2022] [Accepted: 08/17/2022] [Indexed: 12/03/2022]
Abstract
Background Impingement syndrome was shown to be associated with shoulder pain in 44–70% of patients worldwide. It usually occurs due to imbalance and insufficient activation of the rotator cuff (RC) muscles. Aim This study explores the relative effects of handgrip-strengthening exercises on shoulder function, pain, strength, and active range of motion as part of the treatment program for the patients with primary subacromial impingement syndrome. Materials and Methods A total of 58 patients aged 18-50 years with primary subacromial impingement syndrome were randomly enrolled to participate in this single-blind randomized clinical trial. Out of them, only forty patients have eligibly matched the inclusion criteria and randomly assigned to one of two groups to undergo a standardized therapeutic program consisting of two sessions a week for 8 weeks. The control group prescribed ultrasound therapy, ice, and stretching exercises, while the experimental group followed the same program with the addition of handgrip-strengthening exercises (HGSE). Both patients of conventional therapy (control) and handgrip-strengthening exercises (experimental group) were advised to adhere also to stretching and HGSE exercises once a day at home for eight weeks. The outcomes were the shoulder function, pain intensity, muscle strength, and active range of motion of the shoulder joint. Results Patients treated with conventional interventions plus handgrip-strengthening exercises showed the significant improvement over time in shoulder pain and function, strength of rotator cuff muscles, and pain-free range of motion forward flexion, abduction, and external and internal rotation through eight weeks in the experimental group compared to control patient group treated with conventional interventions. In addition, patients of both control and experimental groups showed no significant difference in the adherence to respective home-based stretching and HGSE exercises once a day at home for eight weeks. Conclusions Adding handgrip-strengthening exercises to conventional intervention increases the efficacy of treatment for patients with primary subacromial impingement syndrome in terms of shoulder function, pain, muscle strength, and active range of motion.

Supraspinatus Fatty Infiltration Correlation with Handgrip Strength, Shoulder Strength, and Validated Patient-Reported Outcome Measures in Patients with Rotator Cuff Tears. Kans J Med 2022; 15:155-159. [PMID: 35646246 PMCID: PMC9126862 DOI: 10.17161/kjm.vol15.16343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Accepted: 03/01/2022] [Indexed: 11/30/2022] Open
Abstract
Introduction The purpose of this study was to investigate the relationships between supraspinatus atrophy on magnetic resonance imaging (MRI) and other objective parameters in patients with rotator cuff tears. It was hypothesized that high-grade supraspinatus fatty infiltration would be correlated negatively with handgrip strength, shoulder strength, and patient-reported outcome measures (PROMs). Methods Patients with MRI-proven rotator cuff tears treated by a single sports medicine fellowship-trained orthopaedist at a single institution underwent comprehensive preoperative evaluation including bilateral handgrip and shoulder strength measurements with dynamometers and multiple online questionnaires from the Surgical Outcomes SystemTM (Arthrex, Naples, FL). Available shoulder MRIs were reviewed to grade supraspinatus fatty infiltration severity according to the 5-tier Goutallier system and an alternate 3-tier classification scheme. Difference analysis and Spearman (rho) rank order correlation were applied to the collected data to define the relationships between supraspinatus fatty infiltration and key variables including handgrip strength, shoulder strength, and scores derived from the shoulder PROMs. Results Ninety of the 121 patients enrolled in the study had shoulder MRIs available for review. There was no correlation found between supraspinatus fatty infiltration and handgrip strength, shoulder abduction strength, or any of the seven common shoulder PROM scores evaluated. There was statistically significant, albeit weak, correlation between MRI-derived fatty infiltration and shoulder external rotation strength. Conclusions Contrary to the hypothesis, high-grade supraspinatus fatty infiltration is largely unrelated to and should not be considered predictive of handgrip strength, shoulder strength, or common shoulder PROM scores.

Abstract
An elongation band (EB) is used to improve the physical strength of older adults. However, the evidence of its effect on the upper limb is a deficiency. This study investigated the effectiveness of EB exercises on upper limb function in the elderly. Participants were divided into two groups: EB (n=16) and control (n=14). The EB group performed exercises in a sitting position using an EB while the control group performed active stretching exercises without bands. The exercise regimen consisted of four shoulder joint movements. Each group performed the exercise for 20 min per day, 5 days per week over a period of 2 months. Measurements included upper limb muscle strength, shoulder joint range of motion, and grip strength. Measurements were performed at baseline, and 1 and 2 months after the intervention. Analysis of covariance was used to compare differences between the groups. The EB group demonstrated significant increases in muscle strength (upper trapezius, deltoid, middle trapezius muscle), shoulder joint range of motion (right shoulder flexion, internal rotation, external rotation, left shoulder joint extension), and grip strength. In conclusion, EB exercises increased upper limb muscle strength, shoulder joint range of motion, and grip strength in older adults.

Abstract
Abstract
Aim
To investigate if there is a correlation between grip strength (GS) and rotator cuff (RC) strength in patients with atraumatic shoulder instability (ASI) and to compare the relationship between these two measures with that previously published for a healthy population. Moreover, to determine if testing GS could be incorporated as a surrogate clinical assessment for RC strength in these patients.
Methods
A total of 20 subjects with ASI were included. Out of the 20 patients, eight presented with bilateral instability, which constituted a total of 28 atraumatic unstable shoulders (N = 28). GS was measured using a Jamar hand-dynamometer. External rotation (ER) and internal rotation (IR) strength was tested in inner and outer ranges using a hand-held dynamometer (HHD). Pearson’s correlation test was computed to investigate the relationship. Multiple linear regression was conducted to predict GS based on RC strength.
Results
Significant and strong positive correlations were found between GS and inner-range IR (r = 0.764, P < 0.001), inner-range ER (r = 0.611, P = 0.001), outer-range IR (r = 0.817, P < 0.001), and outer-range ER (r = 0.736, P < 0.001). A significant regression equation was found (F (4, 23) = 13.254, P < 0.001), with an R2 of 0.697 indicating that RC strength explained 69.7% of the variance in GS.
Conclusions
The results support the hypothesis showing that GS is strongly associated with RC strength in ASI patients. The simplicity of handgrip testing allows it to be used in clinical scenarios where sophisticated assessment tools are not available. GS is a convenient means to monitor patient progress during shoulder rehabilitation programs.

Abstract
Background Upper extremity musculoskeletal disorders negatively affect ability to perform activities of daily living, self-care and work. Therefore, outcome measurements that address muscle strength, fatigue resistance, functionality and work physical capacity must be defined to assess and plan specific actions to minimize them. Objective To investigate the association of upper extremity muscle strength with upper extremity fatigue resistance, work ability and upper extremity dysfunction in a sample of workers from a tertiary hospital. Methods Shoulder and elbow isokinetic strength were assessed by Biodex System 4™, isometric hand grip by JAMAR™, upper extremity fatigue resistance by Functional Impairment Test Hand and Neck/Shoulder/Arm (FIT-HaNSA), ability to work by the Work Ability Index and upper extremity dysfunction by the Quick-Disabilities of the Arm, Shoulder and Hand QuickDASH-Br questionnaire. The Nordic questionnaire and Numeric Pain Rating Scale (NPRS) were used for pain description. The associations were analysed by Spearman’s correlation coefficient (rho) (p < 0.05). Results Twenty-seven participants: 59.2% women; mean age 46 years old; 70.3% obese/overweight; 62.9% active with predominantly dynamic muscle contraction work. Besides predominance of good to moderate work ability (81.4%) and comorbidities (37%), all participants had symptoms of the upper extremities for at least 12 months, with a predominance of low-intensity in the shoulder (55.5%). In addition, 88.8% reported pain in other segments. Muscle strength of abduction (rho = 0.49), adduction (rho = 0.40), internal rotation (rho = 0.44) and hand grip (rho = 0.68) presented moderate correlation with FIT-HaNSA. Hand grip (rho = − 0.52) showed moderate correlation with upper extremity dysfunction. Conclusions The results of this preliminary study suggested the association of shoulder strength with fatigue resistance. Also, hand grip strength was associated with upper extremity dysfunction and fatigue resistance. No association was found with the Work Ability Index in this sample. So, it is suggested that hand grip and shoulder strength could be outcome measurements used for future interventions focused on upper extremity preventive exercises to improve strength and fatigue resistance of workers at risk for the development of musculoskeletal disorders. Other individual, psychosocial and organizational risk factors must also be considered as influences on upper extremity function.

Grip and shoulder strength correlation with validated outcome instruments in patients with rotator cuff tears. J Shoulder Elbow Surg 2021; 30:1088-1094.

Abstract
HYPOTHESIS/BACKGROUND The ability to better define preoperatively the extent of rotator cuff (RC) dysfunction is desired. The study's purpose was to prospectively examine the relationships between absolute and percentage loss (affected compared to unaffected) of grip and shoulder strength, and RC dysfunction. METHODS Forty-seven consecutive patients with proven RC tears participated in this study. Prior to surgery, bilateral strengths of grip, shoulder abduction, and shoulder external rotation (ER) were measured with a handheld dynamometer, and subjective outcome measures were gathered. RC tear size was determined via arthroscopy. Patient-reported outcomes were gathered on the day of the examination or via e-mail following initial evaluation. Descriptive statistics, difference analysis, and correlation coefficients (reported as either direct or negative) were used to analyze data. Grip, abduction and ER strengths, and percentage loss of grip, abduction, and ER strengths (percentage loss affected vs. unaffected), and tear size were analyzed in relation to all of the scores on selected subjective outcome measurement tools. The P value was set at .05. RESULTS Fair direct correlations were found between grip strength and the Veterans RAND 12-Item Health Survey (VR-12) mental health scores, ER strength and Simple Shoulder Test (SST), abduction strength, and both the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) function score and SST score. Abduction and ER strengths were also found to possess a fair direct correlation. Fair negative correlations were found between the ASES function score and each of the following: percentage loss of abduction strength, percentage loss of ER strength, and tear size in centimeters. Another fair negative correlation was found between the Single Assessment Numerical Evaluation (SANE) score and tear size in centimeters. DISCUSSION Our findings suggest that as shoulder strength decreases, ipsilateral shoulder RC dysfunction increases. Grip strength was not related to shoulder RC dysfunction. CONCLUSION Grip strength was not found to correlate with RC tears. Those with decreased abduction and ER strengths and low ASES scores should be considered more likely to have an RC tear.

Abstract
Background: Scapular assessment is important in examining overhead athletes, but there is
inconsistency in scapular clinical assessment and its relation to
pathology. Purpose: To determine the relationship between clinical scapular assessment and
biomechanical scapula resting position, shoulder strength, and pitching
shoulder kinematics and kinetics. Study Design: Descriptive laboratory study. Methods: Two clinicians performed scapular assessments and graded the scapula as
presence or absence of scapular dyskinesis. Shoulder external rotation (ER)
and internal rotation (IR) strength were collected. The 3-dimensional
biomechanics of the scapula resting position (upward/downward rotation,
IR/ER, and anterior/posterior tilt) were assessed while participants stood
at rest, and pitching kinematics (maximum shoulder ER, shoulder abduction,
shoulder horizontal abduction, shoulder rotation velocity) and kinetics
(maximum shoulder distraction force) were assessed when participants pitched
off the portable pitching mound that was engineered to meet major league
specifications. Results: A total of 33 high school baseball pitchers (age, 16.3 ± 1.2 years; height,
184.0 ± 6.9 cm; weight, 76.8 ± 20.8 kg; hand dominance: left, 9 [27%];
right, 24 [73%]; pitch velocity, 34.7 ± 2.3 m/s) participated in this study.
Of them, 15 participants had scapular dyskinesis, and 18 had normal
scapulothoracic rhythm. No differences were observed for upward/downward
rotation or anterior/posterior tilt, shoulder ER, shoulder abduction, or
shoulder distraction force, based on the presence of scapular dyskinesis.
Pitchers with scapular dyskinesis demonstrated significantly greater
scapular resting IR position (effect size [ES], 0.80; 95% CI, 0.06 to 1.54;
P = .020), greater nondominant shoulder ER to IR
strength ratio (ES, 0.49; 95% CI, –0.02 to 1.00; P = .018),
and decreased shoulder rotation velocity (ES, 14.66; 95% CI: 12.06 to 17.25;
P = .016). Pitchers with greater anterior tilt
demonstrated greater shoulder rotation velocity (r = –0.48;
P = .006). Conclusion: Pitchers with scapular dyskinesis had greater scapular IR, greater
nondominant shoulder ER to IR strength ratio, and reduced shoulder rotation
velocity. Clinical Relevance: Scapular assessment may be more influenced by differential IR than upward
rotation or anterior tilt. Scapular dyskinesis has no competitive
performance advantage among amateur athletes. Greater understanding is
needed to decipher the critical threshold between beneficial and maladaptive
scapular movement patterns.

Abstract
CONTEXT A baseball-specific training load may influence strength or glenohumeral range of motion, which are related to baseball injuries. Glenohumeral reach tests and grip strength are clinical assessments of shoulder range of motion and upper extremity strength, respectively. OBJECTIVE To examine changes in glenohumeral reach test performance and grip strength between dominant and nondominant limbs and high, moderate, and low baseball-specific training-load groups. DESIGN Repeated-measures study. SETTING University laboratory and satellite clinic. PATIENTS OR OTHER PARTICIPANTS Collegiate baseball athletes (n = 18, age = 20.1 ± 1.3 years, height = 185.0 ± 6.5 cm, mass = 90.9 ± 10.2 kg). MAIN OUTCOME MEASURE(S) Participants performed overhead reach tests (OHRTs), behind-the-back reach tests (BBRTs), and grip strength assessments using the dominant and nondominant limbs every 4 weeks for 16 weeks. Percentage change scores were calculated between testing times. After each training session, participants provided their duration of baseball activity, throw count, and body-specific and arm-specific ratings of perceived exertion. We classified them in the high, moderate, or low training-load group based on each training-load variable: body-specific acute:chronic workload ratio (ACWR), arm-specific ACWR, body-specific cumulative load, and arm-specific cumulative load. Mixed models were used to compare training-load groups and limbs. RESULTS The arm-specific ACWR group demonstrated as main effect for OHRT (F = 7.70, P = .001), BBRT (F = 4.01, P = .029), and grip strength (F = 8.89, P < .001). For the OHRT, the moderate training-load group demonstrated a 10.8% greater increase than the high group (P = .004) and a 13.2% greater increase than the low group (P < .001). For the BBRT, the low training-load group had a 10.1% greater increase than the moderate group (P = .011). For grip strength, the low training-load group demonstrated a 12.1% greater increase than the high group (P = .006) and a 17.7% greater increase than the moderate group (P < .001). CONCLUSIONS Arm-specific ACWR was related to changes in clinical assessments of range of motion and strength. Clinicians may use arm-specific ACWR to indicate when a baseball athlete's physical health is changing.

Abstract
CONTEXT Shoulder pain is the main cause of missed or modified training in competitive swimmers. Shoulder musculoskeletal maladaptations occur to some extent as a consequence of training loads during swimming that may increase the risk of shoulder injury. Further evidence is needed to understand the training intensities at which these maladaptations occur. OBJECTIVE To determine the acute effect of training intensity on the shoulder musculoskeletal physical qualities associated with shoulder injury in competitive swimmers. DESIGN Cross-sectional study. SETTING Indoor swimming pool. PATIENTS OR OTHER PARTICIPANTS Sixteen asymptomatic national- and regional-level swimmers (7 females, 9 males; age = 14.6 ± 3.9 years, height = 160.5 ± 12.7 cm, mass = 55.3 ± 12.5 kg). MAIN OUTCOME MEASURE(S) Bilateral active shoulder-rotation range of motion (ROM), joint position sense, latissimus dorsi length, combined elevation test, and shoulder-rotation isometric peak torque and handgrip peak force normalized to body weight were measured before and immediately after low- and high-intensity swim-training sessions. The intensity of the sessions was determined by the distance swum over or at the pace threshold and confirmed by the swimmer's rating of perceived exertion. RESULTS After the high-intensity training session, shoulder external-rotation ROM (dominant side: P < .001, change = -7.8°; d = 1.10; nondominant side: P = .002, change = -6.5°, d = 1.02), internal-rotator isometric peak torque (dominant side: P < .001, change = -11.4%, d = 0.42; nondominant side: P = .03, change = -6.6%, d = 0.20), and external-rotator isometric peak torque (dominant side: P = .004, change = -8.7%, d = 0.27; nondominant side: P = .02, change = -7.6%, d = 0.25) were reduced. No changes were found in any of the outcome measures after the low-intensity session. CONCLUSIONS Shoulder active external-rotation ROM and rotation isometric peak torque were decreased immediately after a high-intensity training session, possibly increasing the risk of injury during subsequent training. Monitoring these variables may help practitioners adjust and manage training loads to decrease the risk of shoulder injury.

Abstract
The aim of this study was to examine the relationships between isometric handgrip (HG) strength and isokinetic strength data of the glenohumeral rotator muscles. Twelve (Female = 50%) Brazilian Sitting Volleyball (SV) national team players volunteered. Measures of maximal grip strength were obtained by a HG dynamometer Jamar® and isokinetic measures of peak torque (PT) and total work (TW) during shoulder rotations movements were obtained with a Biodex isokinetic dynamometer at speed of 60°/s and 180°/s. Pearson correlation coefficients between isometric HG and isokinetic strength data ranged between 0.23 and 0.72 for the PT and between 0.3 and 0.76 for the isokinetic TW. Results presented positive relationships between HG isometric strength and isokinetic strength of external rotators of the shoulder in SV players. We can suggest that in the absence of isokinetic dynamometers, HG isometric strength measurements could be used to measure strength levels of the external rotator muscles of elite SV players' shoulder, particularly in the TW values.

Abstract
OBJECTIVES To determine the concurrent validity of a sphygmomanometer for assessing shoulder strength in the I, Y and T positions during the athletic shoulder test (ASH test). Force platforms were used as the gold standard measurement tool for this purpose. DESIGN Shoulder strength was assessed using force platforms and a sphygmomanometer, both placed on the floor and the participant positioned prone. One rater assessed strength, taking three measurements in each of the I, Y and T positions, using the sphygmomanometer and force platforms. Concurrent validity was calculated using the force platforms as the gold standard device. SETTING Data was collected within the treatment room of an amateur rugby club. PARTICIPANTS Twenty male amateur rugby players (25.15 years old ± 3.27 years) were recruited for this study. MAIN OUTCOME MEASURES Peak force across the shoulder girdle was assessed using the force platforms and sphygmomanometer which provided values in Newtons (N) and millimetres of mercury (mmHg) respectively. RESULTS Results showed high concurrent validity (Pearsons r = 0.76-0.81) between the sphygmomanometer and the force platform. Coefficient of determination (r2 = 0.59-0.67) showed the sphygmomanometer to have a valid predictive model in the I, Y and T positions. CONCLUSIONS The sphygmomanometer is suitable for monitoring force transfer across the shoulder during the ASH test, and is able to quantify peak force in mmHg. The sphygmomanometer enables coaches and clinicians to accurately quantify force production across the shoulder girdle in order to screen and monitor players at a low cost.

Abstract
Background
Forward head and rounded shoulder posture (FHRSP) is a common clinical postural misalignment. It leads to flexion posture of the spine which increases the amount of tension on the nerve roots, which inversely affects muscle strength and function of the upper extremity. So, this study was conducted to examine the effect of FHRSP on hand grip strength in asymptomatic young adults and to explore the relationship between the craniovertebral angle (CVA) and hand grip strength.
Results
There was no significant difference in hand grip strength between the groups (p = 0.812). There was no correlation between the CVA and right and left hand grip of the normal group (p = 0.840, 0.816 respectively), rounded shoulder posture (RSP) group (p = 0.523, 0.650 respectively), and FHRSP group (p = 0.855, 0.736 respectively). Regarding the right and left hand grip strength, there was no significant difference between the groups (p = 0.798, 0.826 respectively). The right hand grip strength was significantly higher than the left hand for all groups (p = 0.001).
Conclusion
This study displayed that hand grip strength was not affected by FHRSP nor RSP in asymptomatic young adults. Moreover, the degree of the CVA was not associated with an inverse effect on hand grip strength.

J Manipulative Physiol Ther 2019; 41:252-257. [PMID: 29549892 DOI: 10.1016/j.jmpt.2017.09.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2016] [Revised: 07/30/2017] [Accepted: 09/08/2017] [Indexed: 11/19/2022]
Abstract
OBJECTIVE The purpose of this study was to investigate the degree of test-retest reliability of grip strength measurement using a hand dynamometer in patients with shoulder impingement syndrome. METHODS A total of 19 patients (10 women and 9 men; mean ± standard deviation age, 33.2 ± 12.9 years; range 18-59 years) with shoulder impingement syndrome were measured using a hand dynamometer by the same data collector in 2 different testing sessions with a 7-day interval. During each session, patients were encouraged to exert 3 maximal isometric contractions on the affected hand and the mean value of the 3 efforts (measured in kilogram-force [Kgf]) was used for data analysis. The intraclass correlation coefficient (ICC2,1) as well as the standard error of measurement (SEM) and Bland-Altman plot were used to estimate the degree of test-retest reliability and the measurement error, respectively. RESULTS Grip strength data analysis revealed an ICC2,1 score of 0.94, which, based on the Shrout classification, is considered as excellent test-retest reliability of grip strength measurement. The small values of SEMs reported in both sessions (SEM1, 2.55 Kgf; SEM2, 2.39 Kgf) and the small width of the 95% limits of agreement in the Bland-Altman plot (ranging from -7.39 Kgf to 7.03 Kgf) reflected the measurement precision and the narrow variation of the differences during the 2 testing sessions. CONCLUSIONS Results from this study identified excellent test-retest reliability of grip strength measurement in shoulder impingement syndrome, indicating its potential use as an outcome measure in clinical practice.

Abstract
INTRODUCTION The rationale for this case report was to identify the strengths and weaknesses associated with prescribing the Turkish Get-Up as an isometric shoulder and neck exercise. The Turkish getup is an effective tool for isometrically loading the cervical spine and shoulder and can be used with minimal space and equipment. DISCUSSION The Turkish Get-Up was selectively applied as a therapeutic corrective intervention to a patient suffering a mild to moderate cervical, acromio-clavicular and sterno-clavicular joint sprain with associated facet syndrome and muscle spasm. There were concerns that initially gave a guarded prognosis with the realization that further imaging may be warranted after an initial trial. CONCLUSION The Turkish getup is an effective tool for isometrically loading the cervical spine and shoulder and can be used with minimal space and equipment. This exercise allowed the injured patient to integrate full body movement and conditioning with an emphasis on pain free isometric shoulder and cervical spine contractions to re-establish strength and motor control. The patient now has the ability to add to his training and rehabilitation an exercise that can be endlessly progressed to build continuous strength, endurance and motor control.

Abstract
Background: Shoulder impingement syndrome (SIS) is the second most common musculoskeletal condition that causes shoulder pain in the general population. Shoulder girdle muscle imbalance and posterior capsule tightness have been implicated as contributing factors. Objective: The purpose of this study was to investigate the effect of shoulder stability exercises (SSEs) on hand grip strength in patients with unilateral SIS. Methods: A total of 16 patients with a mean age of 32 ± 9.3 years diagnosed with stage II unilateral SIS participated in this study. A standardized SSE programme was conducted in the clinic under the direct 1-to-1 supervision of a physical therapist thrice weekly for 4 weeks for a total of 12 sessions on the affected and non-affected shoulders. The effect of the SSE programme on isometric hand grip strength was analysed. Results: A significant difference (p = .016) was observed in the hand grip strength of the affected shoulder side before and after the intervention, but no significant difference (p = 1.0) was found in the hand grip strength of the non-affected shoulder side post-intervention. Conclusion: The reduction in isometric hand grip strength of the affected shoulder side compared to that of the non-affected shoulder side in the same subject before the intervention shows that SIS significantly affects the hand grip strength of the affected side. SSEs significantly affect the isometric hand grip strength of SIS patients.

Abstract
BACKGROUND Hyperkyphosis is a common postural defect with high prevalence in the 20 to 50 year old population. It appears to compromise proximal scapular stability. Grip and pinch strength are used to evaluate general upper extremity function. OBJECTIVE The aim of this study was to compare pinch and grip strength between young women with and without hyperkyphosis. METHODS Thirty young women (18-40 years old) with hyperkyphosis and 30 healthy women matched for age and body mass index participated in the study. Hyperkyphosis was confirmed by measuring the kyphosis angle with a flexible ruler. Grip strength was measured with the Waisa method and a dynamometer. Pinch strength was assessed with a pinch meter. RESULTS Grip (P= 0.03) and pinch strength (P= 0.04) were significantly lower in women with hyperkyphosis compared to the control group. Kyphosis angle correlated weakly with grip (r= 0.26) and pinch strength (r= 0.23). CONCLUSIONS Hyperkyphotic posture has led to decreased grip and pinch strength compared to people without hyperkyphosis.
