“…This finding may be related to overcompensation during handgrip strength testing on the affected side, but there were no data to support this hypothesis. Although ipsilateral handgrip strength and shoulder strength have been correlated in other previous studies, 40,41 including our own, 13 there was no correlation between fatty infiltration and absolute handgrip strength in the present study.…”

“…In a previous study, we examined the correlation of handgrip and shoulder strength with patient-reported outcomes measures (PROMs) in patients with rotator cuff tears. 13 Herein, the earlier study was extended to include fatty infiltration in the rotator cuff musculature. Historically, Goutallier et al 14 showed on computed tomography (CT) scans that patients undergoing rotator cuff repair had greater fatty tissue infiltration within the rotator cuff compared to their normal asymptomatic counterparts.…”

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. We hypothesized that high-grade supraspinatus fatty infiltration would be negatively correlated 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. We found no correlation between supraspinatus fatty infiltration and handgrip strength, shoulder abduction strength or any of the 7 common shoulder PROM scores we evaluated. There was statistically significant albeit weak correlation between MRI-derived fatty infiltration and shoulder external rotation strength. Conclusions. Contrary to our 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.

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.

“…The main outcome measures used for evaluation of hand motor function recovery after RC tears were the following: Disabilities of the Arm, Shoulder and Hand score (DASH), which is a comprehensive self-administered questionnaire about the symptoms and functioning of the entire upper extremity [ 20 ]; manual muscle testing (MMT), used as a method of measuring upper extremity muscle strength [ 21 , 22 ]; hand grip muscle strength, tested by hydraulic hand dynamometry (HD, in kg) to obtain kinematic parameters of requested movements; and active ROM of the shoulder and elbow were measured [ 13 ]. As a psychometric response scale and measurement instrument for the subjective states of intensity, severity, and nature of experienced pain was used VAS scale [ 2 ].…”

“…Higher levels of psychological distress are also correlated with decreased patient-reported outcomes after surgical intervention. Greater levels of pre- or postoperative psychological distress and subjective well-being (SWB) were not associated with clinically important differences in outcome scores (visual analogue scale (VAS) for pain, hand functionality-evaluated scores) one year after arthroscopic RC repair; similarly, higher levels of distress were not associated with less interval improvement in outcome scores at one year [ 19 , 20 ]. RC tears are a quite common condition that is often incapacitating.…”

Background: Rotator cuff tears are common causes of functional shoulder instability and often lead to arthroscopic rotator cuff repair. A well-programmed rehabilitation leads to successful tendon healing, positive functional recovery and subjective well-being (SWB). Objective: To evaluate the changes in shoulder functioning and SWB pre-, post-outpatient rehabilitation and after one-month follow-up. Materials and Methods: A total of 44 patients were assessed three times: at the beginning (six weeks’ post-surgery), at the end of outpatient rehabilitation (2–3 weeks) and one month after rehabilitation. The outcome measures were the Disabilities of the Arm, Shoulder and Hand score (DASH), active range of motion (ROM), manual muscle testing (MMT), hand dynamometry (HD) and pain level by a Visual Analogue Scale (VAS). SWB was assessed by Rosenberg self-esteem scale (RSES), Positive and Negative Affect Schedule (PANAS) and the Lithuanian Psychological Well-Being Scale (LPWBS). Results are presented as a difference between periods. Results: Affected shoulder motor function (MMT, HD and ROM) significantly improved in three periods (p < 0.05); however, major recovery was observed in the follow-up period. VAS scores meaningfully decreased over all stages and negatively correlated with motor function recovery (p < 0.05). DASH rates exhibited significant retrieval in all phases, especially in follow-up. SWB results demonstrated the larger effects of self-evaluation in follow-up, improved daily functions and psychological wellness, then negative emotions significantly decreased (p < 0.05). Conclusions: The experienced pain and psychosocial factors significantly influence functional recovery of the shoulder during rehabilitation. The improvement in motor function, ability and pain relief during rehabilitation increases level of SWB, psychological wellness and positive emotional affect in long-term context.
