Assessment of Upper Extremity Function.

Assessment of upper extremity function either before or after surgical treatment has been a rapidly evolving field. A reproducible, accurate, and valid assessment tool provides the ability to compare surgical interventions, evaluate physical therapy regimens, and assess novel assistive and restorative technologies. The purpose of this article is to detail the various upper extremity assessment tools and introduce the concept of real-world data acquisition of upper extremity function.

Rationale and design of the ARCUS: Effects of trAnsRadial perCUtaneouS coronary intervention on upper extremity function.

OBJECTIVE: The aim of this study is to provide a complete insight in the access-site morbidity and upper extremity function after Transradial Percutaneous Coronary Intervention (TR-PCI). BACKGROUND: In percutaneous coronary intervention the Transradial Approach (TRA) is gaining popularity as a default technique. It is a very promising technique with respect to post-procedure complications, but the exact effects of TRA on upper extremity function are unknown. METHODS AND RESULTS: The effects of trAnsRadial perCUtaneouS coronary intervention on upper extremity function (ARCUS) trial is a multicenter prospective cohort study that will be conducted in all patients admitted for TR-PCI. Clinical outcomes will be monitored during a follow-up of 6 months, with its primary endpoint at two weeks of follow-up. To investigate the complete upper extremity function, a combination of physical examinations and validated questionnaires will be used to provide information on anatomical integrity, strength, range of motion (ROM), coordination, sensibility, pain, and functioning in everyday life. Procedural and material specifications will be registered in order to include all possible aspects influencing upper extremity function. CONCLUSIONS: Results from this study will elucidate the effect of TR-PCI on upper extremity function. This creates the opportunity to further optimize TR-PCI, to make improvements in functional outcome and to prevent morbidity regarding full upper extremity function. © 2016 Wiley Periodicals, Inc.

Revealing the impact of local access-site complications and upper extremity dysfunction post transradial percutaneous coronary procedures.

OBJECTIVES: Little is known about local access-site complications and upper extremity dysfunction after transradial percutaneous coronary procedures (TR-PCP). This systematic review study aimed to summarise the current knowledge on the incidences of access-site complications and upper extremity dysfunction after TR-PCP. METHODS: Two independent, trained investigators searched MEDLINE, EMBASE and CENTRAL for eligible studies published before 1 January 2015. Also, they hand-searched the conference proceedings of the annual scientific sessions of the American College of Cardiology, the American Heart Association, European Society of Cardiology, and the Trans-catheter Cardiovascular Therapeutics. Inclusion criteria were cohort studies and clinical trials discussing the incidence of access-site complications and upper extremity function after transradial percutaneous coronary intervention (TR-PCI) and/or transradial coronary angiography (TR-CAG) as endpoints. RESULTS: 176 articles described access-site complications. The incidence is up to 9.6 %. Fourteen articles described upper extremity dysfunction, with an incidence of up to 1.7 %. Upper extremity dysfunction was rarely investigated, hardly ever as primary endpoint, and if investigated not thoroughly enough. CONCLUSION: Upper extremity dysfunction in TR-PCP has never been properly investigated and is therefore underestimated. Further studies are needed to investigate the magnitude, prevention and best treatment of upper extremity dysfunction. Optimising TR-PCP might be achieved by using slender techniques, detection of upper extremity dysfunction and early referral to a hand rehabilitation centre.

The influence of axillary surgery and radiotherapeutic strategy on the risk of lymphedema and upper extremity dysfunction in early breast cancer patients.

PURPOSE: To explore the risk factors for breast cancer-related lymphedema (BCRL) and upper extremity dysfunction (UED) in patients with early breast cancer after modern comprehensive treatment and to compare the toxicity of different treatment strategies. METHODS: From 2017 to 2020, a total of 1369 female patients with pT1-3N0-1M0 breast cancer who underwent adjuvant radiotherapy in our centre were retrospectively reviewed. BCRL and UED were identified by the Norman and QuickDASH questionnaires. The incidence, severity and risk factors for BCRL and UED were evaluated. RESULTS: After a median follow-up of 25 months, a total of 249 patients developed BCRL; axillary lymph node dissection (ALND), increased number of dissected nodes, right-sided and hypofractionated radiotherapy containing RNI were found to be significant risk factors (all p values < 0.05). The sentinel lymph node biopsy (SLNB)+ regional nodal irradiation (RNI) group had a significantly lower BCRL risk than the ALND + RNI group (10.8% vs. 32.5%, HR = 0.426, p = 0.020), while there was no significant difference between ALND vs. ALND + RNI or SLNB vs. SLNB + RNI. A total of 193 patients developed UED, and ALND (p = 0.02) was the only significant risk factor. The SLNB + RNI group had a significantly decreased risk of UED compared with the ALND + RNI group (7.5% vs. 23.9%, HR = 0.260, p = 0.001), and there was no significant difference between SLNB vs. SLNB + RNI or ALND vs. ALND + RNI. CONCLUSION: Aggressive ALND remains the primary risk factor for BCRL and UED while RNI does not. Thus, replacing ALND with tailored radiotherapy would be an effective preventive strategy in early breast cancer patients.

Differences in neural pathways are related to the short- or long-term benefits of constraint-induced movement therapy in patients with chronic stroke and hemiparesis: a pilot cohort study.

Background No previous studies have determined how the post-stroke integrity of non-corticospinal neural pathways relates to the efficacy of constraint-induced movement therapy (CIMT). Objectives We aimed to clarify the relationship between several non-corticospinal neural pathway integrities and the short- and long-term benefits of CIMT. Methods This was a pilot cohort study (UMIN registration number: R00027136UMIN000023566), for which we enrolled 13 patients with chronic stroke and hemiparesis who had undergone CIMT. We assessed patients' motor function improvement by comparing the Fugl-Meyer Assessment (FMA) scores, as well as the Amount of Use (AOU) and Quality of Movement (QOM) scales of the Motor Activity Log before, immediately after (short-term), and 6 months after (long-term) CIMT. We assessed neural pathway integrity by calculating fractional anisotropy (FA) in diffusion tensor images acquired before CIMT. We then assessed correlations between FA and short- and long-term post-CIMT motor function improvements. Results The patients showed significant improvements in all functional assessments at both short- and long-term follow-ups. Immediate FMA score improvements were significantly correlated with FA of the affected anterior limb of the internal capsule (ALIC), body of the corpus callosum, column and body of the fornix (CBF), cingulate cortex (CgC), cerebral peduncle (CP), and posterior limb of the internal capsule. Six-month FMA score improvements were significantly correlated with FA of the affected ALIC, CgC, CBF, CP, and superior frontooccipital fasciculus. Conclusions The integrity of the affected corticospinal and non-corticospinal motor pathways was associated with CIMT-induced motor learning at least 6 months after CIMT.

Mechanisms, Treatment, and Patient Outcome of Iatrogenic Injury to the Brachial Plexus-A Retrospective Single-Center Study.

BACKGROUND: Injury to the brachial plexus is a devastating condition, with severe impairment of upper extremity function resulting in distinct disability. There are no systematic reports on epidemiology, causative mechanisms, treatment strategies. or outcomes of iatrogenic brachial plexus injury (iBPI). METHODS: We screened all cases of iatrogenic nerve injuries recorded between 2007 and 2017 at a single specialized institution. Mechanism of iBPI, type of previous causative intervention, location and type of the lesion as well as the type of revision surgery and functional patient outcome were analyzed. RESULTS: We identified 14 cases of iBPI, which all presented with significant impairment of upper extremity motor function (at least 1 muscle Medical Research Council grade 0). Neuropathic pain was present in most patients (11/14). Orthopedic shoulder procedures such as rotator cuff fixation, arthroplasty, and repositioning of a clavicle fracture accounted for iBPI in 7 of 14 patients. Other reasons for iBPI were resection or biopsy of a peripheral nerve sheath tumor in 3 patients or lymph node situated at the cervicomediastinal area in 2 patients. Mechanisms also included transaxillary rib resection in one and sternotomy in another patient. The treatment of iBPI was conducted according to each individual's needs and included neurolysis in 4, nerve grafting in 9, and nerve transfers in 1 patient. We found improved symptoms after treatment in most patients (11/14). CONCLUSIONS: Most common causes for iBPI were shoulder surgery and resection or biopsy of peripheral nerve sheath tumor and lymph nodes. Early referral to specialized peripheral nerve centers may help to improve functional patient outcome.

Does pectoralis major flap harvesting induce upper extremity dysfunction?

OBJECTIVE: To evaluate the effect of pectoralis major myocutaneous (PMM) flap reconstruction on upper extremity dysfunction. METHODS: Patients undergoing PMM flap reconstruction following head and neck cancer resection were enrolled. The control group comprised age-, sex- and clinical characteristic-matched patients undergoing non-PMM flap reconstruction. All patients completed the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire preoperatively and >1 year postoperatively. RESULTS: There was no significant difference between pre- and postoperative DASH scores in the control group (n = 46; 2.38 ± 3.33 and 2.99 ± 4.21, respectively). In the PMM flap group (n = 46), the postoperative DASH score was significantly higher than the preoperative score (7.00 ± 9.13 and 2.44 ± 3.50, respectively). In the PMM flap group, flap size was significantly associated with postoperative DASH score. CONCLUSION: PMM flap reconstruction has a small but significant negative effect on upper extremity dysfunction.
