Background: Intact sensory-motor system provides kinesthesia for maintaining joint stability. Joint proprioception or joint kinesthetic sensation is often used alternately to describe a deep sensation of joint motion and joint position sense. Mechanoreceptors located in superficial layer of joint capsule, muscle spindle, golgi tendon organ complex and ligaments around joint provides joint kinesthetic sensation. Frozen shoulder or adhesive capsulitis is one of the common musculoskeletal disorders encountered in Indian population with a prevalence of almost 50% older patients with diabetes and 2-10% in non-diabetic patients. This study assessed joint kinesthetic sensation during shoulder movements in people with frozen shoulder and healthy controls which may be affected due to presence of disease process or pain. Authors hypothesized that pain and alterations in non-contractile tissues (mainly capsule) around shoulder joint due to frozen shoulder may interfere with the joint kinesthetic sensation.Methods: Case group consisted of 41 participants with frozen shoulder and 41 healthy participants without shoulder pathology. Joint kinesthesia was assessed in frozen shoulders and dominant shoulders using angle reproduction test by actively reproducing the target angle placed passively by the therapist during flexion, abduction, medial and lateral rotation movements. The angle reproduced was measured using universal goniometer by the same therapist and 3 readings were recorded.Results: Results indicate significant differences between the mean difference of angle reproduction test during shoulder movements in cases of frozen shoulder and healthy group (p value <0.05).Conclusions: Significant shoulder kinesthetic deficits were observed in patients with unilateral frozen shoulder. Therefore, clinicians should consider rehabilitation of kinesthesia in treatment of patients with frozen shoulder.

<p><strong>BACKGROUND</strong><strong>: </strong>Proprioception plays an integral role in the neuromotor control of the knee joint. The objective of this study was to evaluate the relationship of knee joint proprioception deficit and regular exercise activities with obesity.</p><p><strong>MATERIAL/METHOD</strong><strong>: </strong>In this case control study, we had 60 participants, aged 18 to 35 in four groups (15 athletes obese; 15 athletes with normal weight; 15 non-athletes obese; 15 non-athletes with normal weight). The average Body Mass Index for the obese groups was 33.50±(3.10) kg/m<sup>2</sup> and for the normal weight groups was 23.77±(2.94) kg/m<sup>2</sup>. We used a Biodex Multi-Joint System 4 Isokinetic Dynamometer to examine proprioception acuity as the amount of a subject's error when trying to reproduce a test knee extension angle (a measure of the joint position sense). We tested proprioception actively (active reproduction test; AAR) and passively (passive reproduction test; PAR) in the right leg.</p><p><strong>RESULTS: </strong>The non-athlete obese group had significantly poorer proprioception acuity in the knee extension movement compared to the normal weight groups and also compared to the athlete obese group. For knee active angle reproduction test AAR, a significant difference was found (p=0.011). The results for passive angle reproduction test PAR, revealed no significant differences between the four groups (p=0.596).</p><p><strong>CONCLUSIONS:</strong> The obese groups showed a deficit in the proprioception function in knee extension movement. Furthermore, the findings suggest that doing regular weight bearing training is associated with better proprioceptive function, even in obese groups. It could manifest that the deleterious effect of obesity on the knee joint proprioception might be stronger than the beneficial influence of exercise training.</p>

Abstract. The current study investigated individual differences in the flexibility of peripersonal space (i.e., representational space near the body), specifically in relation to trait claustrophobic fear (i.e., fear of suffocating or being physically restricted). Participants completed a line bisection task with either a laser pointer (Laser condition), allowing for a baseline measure of the size of one’s peripersonal space, or a stick (Stick condition), which produces expansion of one’s peripersonal space. Our results revealed that individuals high in claustrophobic fear had larger peripersonal spaces than those lower in claustrophobic fear, replicating previous research. We also found that, whereas individuals low in claustrophobic fear demonstrated the expected expansion of peripersonal space in the Stick condition, individuals high in claustrophobic fear showed less expansion, suggesting decreased flexibility. We discuss these findings in relation to the defensive function of peripersonal space and reduced attentional flexibility associated with trait anxieties.

OBJECTIVEThe decision-making in neonatal brachial plexus palsy (NBPP) treatment continues to have many areas in need of clarification. Graft repair was the gold standard until the introduction of nerve transfer strategies. Currently, there is conflicting evidence regarding outcomes in patients with nerve grafts versus nerve transfers in relation to shoulder function. The objective of this study was to further define the outcomes for reconstruction strategies in NBPP with a specific focus on the shoulder.METHODSA cohort of patients with NBPP and surgical repairs from a single center were reviewed. Demographic and standard clinical data, including imaging and electrodiagnostics, were gathered from a clinical database. Clinical data from physical therapy evaluations, including active and passive range of motion, were examined. Statistical analysis was performed on the available data.RESULTSForty-five patients met the inclusion criteria for this study, 19 with graft repair and 26 with nerve transfers. There were no significant differences in demographics between the two groups. Understandably, there were no patients in the nerve grafting group with preganglionic lesions, resulting in a difference in lesion type between the cohorts. There were no differences in preoperative shoulder function between the cohorts. Both groups reached statistically significant improvements in shoulder flexion and shoulder abduction. The nerve transfer group experienced a significant improvement in shoulder external rotation, from −78° to −28° (p = 0.0001), whereas a significant difference was not reached in the graft group. When compared between groups, there appeared to be a trend favoring nerve transfer in shoulder external rotation, with the graft patients improving by 17° and the transfer patients improving by 49° (p = 0.07).CONCLUSIONSIn NBPP, patients with shoulder weakness experience statistically significant improvements in shoulder flexion and abduction after graft repair or nerve transfer, and patients with nerve transfers additionally experience significant improvement in external rotation. With regard to shoulder external rotation, there appear to be some data supporting the use of nerve transfers.

Abstract Background The deltoid is a large triangular muscle at the shoulder. It attaches proximally to the clavicle, acromion and scapula, while distally it attaches to the lateral deltoid tuberosity. Ruptures are rare, and the literature only reports cases of proximal detachment. In this article, we report the first case of distal traumatic deltoid muscle detachment and its successful management. Case A young female sustained a traumatic injury following a Jet Ski accident with loss of consciousness. A complete distal rupture of the deltoid muscle was diagnosed after the basic functions were regained and a thorough musculoskeletal examination could be conducted. A conservative approach helped her to regain an acceptable shoulder function, but there was persistent pain upon activity and cosmetic scarring. The patient underwent surgical reconstruction. Postoperatively, she recovered satisfactorily. Discussion Distal detachment of the deltoid muscle is rare. The choice for surgical treatment may be undertaken based on several factors including functional status and patient-based assessment.

Background: While platelet-rich plasma (PRP) has been widely studied for musculoskeletal disorders, few studies to date have reported its use for adhesive capsulitis (AC). Fully characterized and standardized allogenic PRP may provide clues to solve the underlying mechanism of PRP with respect to synovial inflammation and thus may clarify its clinical indications. Purpose: To clinically evaluate the safety and efficacy of a fully characterized pure PRP injection in patients with AC and to assess the effects of pure PRP on synoviocytes with or without inflammation in vitro. Study Design: Controlled laboratory study and cohort study; Level of evidence, 3. Methods: For the clinical analysis, a total of 15 patients with AC received an ultrasonography-guided intra-articular PRP injection and were observed for 6 months. Pain, range of motion (ROM), muscle strength, shoulder function, and overall satisfaction in the patients were evaluated using questionnaires at 1 week as well as at 1, 3, and 6 months after the PRP injection and results were compared with the results of a propensity score−matched control group that received a corticosteroid injection (40 mg triamcinolone acetonide). For the in vitro analysis, synoviocytes were cultured with or without interleukin-1β (IL-1β) and PRP. The gene expression of proinflammatory and anti-inflammatory cytokines as well as matrix enzymes and their inhibitors was evaluated. Results: At 6-month follow-up, pure PRP significantly decreased pain and improved ROM, muscle strength, and shoulder function to levels comparable with those after a corticosteroid injection. All pain values, strength measurements, and functional scores significantly improved up to 6 months in the PRP group, but these measures improved up to 3 months and then were decreased at 6 months in the corticosteroid group. ROM was significantly improved in the 2 groups at 6 months compared with baseline. Allogenic PRP did not cause adverse events. For the in vitro findings, PRP induced inflammation but significantly improved the IL 1β−induced synovial inflammatory condition by decreasing proinflammatory cytokines such as IL-1β, tumor necrosis factor−α, IL-6, cyclooxygenase-2, and microsomal prostaglandin E synthase−1 and decreased matrix enzymes (matrix metalloproteinase−1, −3, and −13 as well as a disintegrin and metalloproteinase with thrombospondin motifs−4 and −5) and further increasing anti-inflammatory cytokines such as vasoactive intestinal peptide. Conclusion: This study showed that PRP decreased pain and improved shoulder ROM and function to an extent comparable with that of a corticosteroid in patients with AC. Allogenic pure PRP acted in a pleiotropic manner and decreased proinflammatory cytokines only in the inflammatory condition. Clinical Relevance: Allogenic PRP could be a treatment option for the inflammatory stage of AC.

Background and Objectives: The purpose of this study was to investigate the effects of microcurrent stimulation on pain, shoulder function, and grip strength in patients with rotator cuff repair. Materials and Methods: This randomized single-blind controlled trial was conducted on inpatients of the rehabilitation department, and included 28 patients who underwent rotator cuff repair. Participants were randomly assigned to the experimental group (n = 14), treated with microcurrent stimulation, and the control group (n = 14), treated with false microcurrent stimulation. The microcurrent stimulation administered to the experimental group underwent general physical therapy and microcurrent stimulation three times a week for 4 weeks. Results: Changes in pain, range of motion in shoulder, simple shoulder test, and grip strength were assessed before and after the intervention. Both groups showed a significant decrease in pain and shoulder function (t = 27.412, 22.079, 19.079, and 18.561; p < 0.001), and grip strength showed a significant increase (t = −8.251 and −9.946; p < 0.001). The experimental group that underwent microcurrent stimulation exhibited a significant effect on pain, shoulder function, and grip strength compared with the control group that underwent false microcurrent stimulation (t = −2.17, −2.22, and 2.213; p = 0.039, 0.035, and 0.036). Conclusions: This study confirmed that microcurrent stimulation is effective for the treatment of rotator cuff repair patients.
