This study aimed to determine the effects of electromyography (EMG)-triggered pedaling training to improve motor functions in the lower extremities, muscle activation, gait, postural balance, and activities of daily living in stroke patients. Subjects were randomly allocated to two groups: the EMG-triggered pedaling training group (EMG-PTG, n = 21) and the traditional pedaling training group (TPTG, n = 20). Both groups trained five times per week for four weeks, with 50 min per session. Lower extremity motor function was assessed using the Fugl–Meyer Assessment (FMA). Muscle activation of the four muscles of the lower extremities was assessed using eight-channel electromyography, while gait ability was assessed using GaitRite. Postural balance was assessed using the Berg balance scale (BBS), the timed up and go (TUG), and functional reach tests (FRT). Daily activities were assessed using the Modified Barthel Index (MBI). For lower extremity motor function, gait ability, balance ability, and activities of daily living, the EMG-PTG showed significant improvement compared to TPTG (p < 0.05). These results suggest that EMG-triggered pedaling training effectively improves lower extremity motor function, muscle activation, gait, postural balance, and activities of daily living in stroke patients.

Subacute Stroke

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.

Abstract In the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Sixth Edition, range of motion (ROM) is used to calculate the physical examination modifier when the diagnosis-based impairment (DBI) method is used, ie, Table 15-8, Physical Examination Adjustment: Upper Extremities, and Table 16-7, Physical Examination Adjustment: Lower Extremities. The DBI method is preferable for calculating upper and lower extremity ratings, but in instances specified by the regional grid, the evaluator may choose to use the ROM method, typically because it yields a higher impairment rating. The article outlines the steps for measuring ROM. Invalid results on the day of testing are declared after three consecutive efforts if the three measurements for a given plane of motion vary by more than 10 degrees from the average (mean) of these three measurements. The process can be tried again another day, or the DBI method can be used. All ROM measurements should be rounded to the nearest number ending in zero, and a figure provides examples of suitable annotations. Adjustments for functional history can be made if ROM is the only method used for rating, if results are deemed reliable and consistent with results from an activities of daily living questionnaire or other valid functional report, and if the current ROM impairment does not adequately capture the full impairment.

BACKGROUND: Robot-assisted therapy (RT) has become a promising stroke rehabilitation intervention. OBJECTIVE: To examine the effects of short-term upper limb RT on the rehabilitation of sub-acute stroke patients. METHODS: Subjects were randomly assigned to the RT group (n= 23) or conventional rehabilitation (CR) group (n= 22). All subjects received conventional rehabilitation therapy for 30 minutes twice a day, for 2 weeks. In addition, the RT group received RT for 30 minutes twice a day, for 2 weeks. The outcomes before treatment (T0) and at 2 weeks (T1) and 1 month follow-up (T2) were evaluated in the patients using the upper limb motor function test of the Fugl-Meyer assessment (FMA) the Motricity Index (MI), the Modified Ashworth Scale (MAS), the Functional Independence Measure (FIM), and the Barthel Index (BI). RESULTS: There were significant improvements in motor function scales (P< 0.001 for FMA and MI) and activities of daily living (P< 0.001 for FIM and BI) but without muscle tone (MAS, P> 0.05) in the RT and CR groups. Compared to the CR group, the RT group showed improvements in motor function and activities of daily living (P< 0.05 for FMA, MI, FIM, BI) at T1 and T2. There was no significant difference between the two groups in muscle tone (MAS, P> 0.05). CONCLUSIONS: RT may be a useful tool for sub-acute stroke patients’ rehabilitation.

Aim: to determine if dynamic balance is related to activities of daily living (ADL) dependence in stroke patients. Methods: a cross-sectional study was carried out. The Barthel index (BI) was used to assess ADL dependence. The Timed Up and Go Test (TUG) and the Four Square Step Test (FSST) were used to evaluate dynamic balance. A Spearman correlation was used assuming a data abnormality in the performance of TUG and FSST and considering a significance of p<0.05. Results: 62 stroke patients were evaluated. The BI showed correlations with the performance of the TUG and the FSST. These correlations were also found between performance of both balance tests and ADLs, such as bathing, moving, and going up and down stairs. In contrast to TUG, correlations were estimated between the ADL related to dressing and the performance of the FSST. Conclusion: dynamic balance evaluated by the TUG and the FSST showed correlations with the ADL dependency in stroke patients.
