Extremity Dysfunction After Large‐Bore Radial and Femoral Arterial Access

Background The use of large‐bore (LB) arterial access and guiding catheters has been advocated for complex percutaneous coronary intervention. However, the impact of LB transradial access (TRA) and transfemoral access (TFA) on extremity dysfunction is currently unknown. Methods and Results The predefined substudy of the COLOR (Complex Large‐Bore Radial PCI) trial aimed to assess upper and lower‐extremity dysfunction after LB radial and femoral access. Upper‐extremity function was assessed in LB TRA‐treated patients by the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire and lower‐extremity function in LB TFA‐treated patients by the Lower Extremity Functional Scale questionnaire. Extremity pain and effect of access site complications and risk factors on extremity dysfunction was also analyzed. There were 343 patients who completed analyzable questionnaires. Overall, upper and lower‐extremity function did not decrease over time when LB TRA and TFA were used for complex percutaneous coronary intervention, as represented by the median Quick Disabilities of the Arm, Shoulder, and Hand score (6.8 at baseline and 2.1 at follow‐up, higher is worse) and Lower Extremity Functional Scale score (56 at baseline and 58 at follow‐up, lower is worse). Clinically relevant extremity dysfunction occurred in 6% after TRA and 9% after TFA. A trend for more pronounced upper‐limb dysfunction was present in female patients after LB TRA ( P =0.05). Lower‐extremity pain at discharge was significantly higher in patients with femoral access site complications ( P =0.02). Conclusions Following LB TRA and TFA, self‐reported upper and lower‐limb function did not decrease over time in the majority of patients. Clinically relevant limb dysfunction occurs in a small minority of patients regardless of radial or femoral access. Registration URL: https://www.clinicaltrials.gov ; Unique identifier: NCT03846752.

Effectiveness of a Novel Contralaterally Controlled Neuromuscular Electrical Stimulation for Restoring Lower Limb Motor Performance and Activities of Daily Living in Stroke Survivors: A Randomized Controlled Trial

Background. Contralaterally controlled neuromuscular electrical stimulation (CCNMES) is a novel electrical stimulation treatment for stroke; however, reports on the efficacy of CCNMES on lower extremity function after stroke are scarce. Objective. To compare the effects of CCNMES versus NMES on lower extremity function and activities of daily living (ADL) in subacute stroke patients. Methods. Forty-four patients with a history of subacute stroke were randomly assigned to a CCNMES group and a NMES group ( n = 22 per group). Twenty-one patients in each group completed the study per protocol, with one subject lost in follow-up in each group. The CCNMES group received CCNMES to the tibialis anterior (TA) and the peroneus longus and brevis muscles to induce ankle dorsiflexion motion, whereas the NMES group received NMES. The stimulus current was a biphasic waveform with a pulse duration of 200 μs and a frequency of 60 Hz. Patients in both groups underwent five 15 min sessions of electrical stimulation per week for three weeks. Indicators of motor function and ADL were measured pre- and posttreatment, including the Fugl–Meyer assessment of the lower extremity (FMA-LE) and modified Barthel index (MBI). Surface electromyography (sEMG) assessments included average electromyography (aEMG), integrated electromyography (iEMG), and root mean square (RMS) of the paretic TA muscle. Results. Values for the FMA-LE, MBI, aEMG, iEMG, and RMS of the affected TA muscle were significantly increased in both groups after treatment ( p < 0.01 ). Patients in the CCNMES group showed significant improvements in all the measurements compared with the NMES group after treatment. Within-group differences in all post- and pretreatment indicators were significantly greater in the CCNMES group than in the NMES group ( p < 0.05 ). Conclusion. CCNMES improved motor function and ADL ability to a greater extent than the conventional NMES in subacute stroke patients.

Effect of Scapular Kinesiotaping as an Adjunct to Dynamic Neuromuscular Stabilization Exercises on Upper Extremity Functions in Stroke Patients

Background and Purpose: Stroke is one of the leading causes of death and disability in India. Upper extremities get more affected in Middle cerebral artery syndrome. Stroke patients have lack of functional ability of upper extremity due to scapular malalignment resulting from paralysis of the scapular muscles. Kinesiotape helps to realign the muscles and thus it becomes easy to activate or inhibit them. We hypothesised that Dynamic Neuromuscular Stabilisation exercises along with kinesiotape could improve upper extremity function. Methodology: Ethical clearance was obtained. Informed consent was taken. 30 patients were selected according to inclusion and exclusion criteria. 15 subjects were randomly divided into experimental and control group. Subjects were given Dynamic neuromuscular stabilisation exercises for scapular strengthening. The experimental group was given Kinesiotaping to the scapula using muscle technique. Pre and post treatment assessment was done using Upper Extremity Function Index, grip strength and scapular abduction position with MB ruler. Result: The intergroup comparison revealed a highly significant difference for upper extremity function index and grip strength whereas scapular abduction was not significant. Conclusion: The Scapular Kinesiotaping as an adjunct to Dynamic Neuromuscular Stabilization Exercises is significantly effective to improve upper extremity functions and grip strength in post stroke patients. Key words: Stroke, Upper Extremity Functions, Dynamic Neuromuscular Stabilization Exercises, Scapular Kinesiotaping.

Examining the effects of upper extremity function and arm sling type on balance, gait and fall risk in patients with hemiparesis

Background/aims Previous studies have reported conflicting results on the effects of arm slings on the balance and gait of patients with hemiparesis. These previous studies did not consider the ability to control the upper extremity on the affected side as a factor that could affect the patient's balance or gait when an arm sling was applied. Hence, the aim of this study was to investigate the effect of upper extremity function in the affected side and arm position according to the sling type on balance, gait and fall. Methods A total of 31 stroke patients participated in the study and were assigned to two groups according to upper extremity function (low-score group and high-score group). Under three conditions (no sling, forearm sling and shoulder sling), a fall risk test, postural stability test and limits of stability test were performed and speed, stride duration, step length and total time were measured. Results When the high-score group wore forearm slings, the static and dynamic balance ability decreased and the fall risk increased. When the low-score group wore forearm slings and shoulder slings, the static and dynamic balance ability increased and the fall risk decreased. The high-score group had a shorter gait time when wearing shoulder slings. When the low-score group wore forearm slings, the speed and step length increased and the total time decreased, enhancing the overall gait ability. Conclusions For stroke patients with better upper extremity control ability, shoulder slings are more appropriate. For patients with poor upper extremity control ability, forearm slings are more appropriate. Using the appropriate sling according to the upper extremity function can improve balance and gait ability and fall risk can be reduced.

Feasibility of Using a Commercial Board Game to Assess Upper Extremity Function in Older Adults

Upper extremity function, particularly the hand, declines with aging and is predictive of executive ability and independence. Standard assessments typically focus on strength partly due to a lack of easily administered functional tasks requiring multi-joint coordination and precision grasp. This study aimed to determine the feasibility of using an inexpensive board game to assess upper extremity function in older adults. Six healthy older adults (77 +/- 5.1 years) completed reaching tasks using the Connect4® game that requires grasping and placing small discs into a vertical board. Tasks included different hand configurations (unilateral, bilateral), and two dual-task conditions (serial subtraction by 7s and placing colored discs to match specific color patterns). The time to complete each task was recorded. For comparison purposes, participants completed a standardized pegboard test (Purdue Pegboard) using one or both hands. Connect4 results were similar to age-normative findings reported for the Purdue Pegboard. Dominant versus non-dominant hand performance did not differ while bilateral coordination tasks were slower than unilateral tasks for both the Purdue Pegboard (p&lt;0.05) and Connect4 (p&lt;0.01). Pegboard and Connect4 times were moderately to strongly correlated for all hand configurations. Dual-task conditions using Connect4 led to longer completion times (p&lt;0.05). Preliminary results support the use of Connect4 as a functional upper extremity assessment tool for older adults. It is inexpensive, engaging, easy to use, and allows for cognitive-motor assessment using dual-task protocols, a critical factor in maintaining functional independence in older individuals. Further research will include a formal validation study across a wider age range.

Relationship between Trunk Impairment and Upper Extremity Function, and Its Impact on Activities of Daily Living in Chronic Stroke Survivors

Background: Stroke often leads to significant impairment of trunk and upper extremity functions, which is associated with decreased quality of life and functional performance in all domains. Trunk stability and control is considered to be a prerequisite for upper extremity function in stroke survivors. Therefore, it is important to evaluate the relationship between trunk impairment and upper extremity function in stroke survivors which may help in improving their ADL’s by giving proper treatment. Methods: 20 chronic stroke survivors with age group between 40 – 80 years were included in this study. Trunk impairment, upper extremity function and activities of daily living of all the participants were determined using trunk impairment scale, Chedoke arm and hand activity inventory scale (version 8) and functional independence measure – motor scoring scale. Results: Using Karl Pearson’s Correlation coefficient, moderate positive correlation was observed between TIS and CAHAI-8. Strong positive correlation was noted between TIS and FIM-M, whereas, moderate positive correlation was noted between CAHAI-8 and FIM-M which was found to be highly statistically significant. Conclusion: Our study concludes that, a moderate positive correlation exists between trunk impairment and upper extremity function in chronic stroke survivors. The study also reveals that, both trunk impairment and upper extremity function has strong and moderate correlation on their activities of daily living. Keywords: Stroke, trunk function, paretic arm, functional performance, stroke rehabilitation.

A Novel Virtual Reality Training Strategy for Poststroke Patients: A Randomized Clinical Trial

Stroke patients suffer impairments including sensory, motor, visual, and cognitive areas, as well as gait and balance manifestations making activities of daily living difficult. In such conditions, virtual reality training can be a potential rehabilitation tool in comparison to conventional physical therapy to cater to the burden of this disability; hence, this randomized clinical trial compared the effects of virtual reality training and conventional physical therapy on balance and lower extremity function in stroke patients. The sample of 68 poststroke participants from Kanaan Physical Therapy and Spine Clinic, Lahore, Pakistan, were divided into N = 34 cases each using the lottery method with one group given virtual reality training and the other received conventional physical therapy. Each group received 60 minutes intervention, 3 days per week for 6 weeks. The Berg balance scale and the Fugl-Meyer assessment-lower extremity scale were employed for data collection preintervention, immediate postintervention, and 6 weeks postintervention. The statistically significant differences between virtual reality and conventional physical therapy groups for the Berg Balance score ( p < 0.001 ), Fugl-Meyer assessment (FMA)-lower extremity domains of FMA-motor function ( p < 0.001 ), FMA-joint pain, and joint range ( p < 0.001 ); however, there is no significant difference p = 0.202 for time vs. group interaction and significant ( p < 0.001 ) for the time main effect for FMA sensation. Hence, virtual reality training is more effective to restore balance and lower extremity function compared to conventional physical therapy in stroke patients. The results of the study have significant implications for the clinicians with better case management enhancing quality of life of patients along with the dearth of local literature, thus providing base for future research from a developing country’s perspective.
