“…Due to the nature of the TKA patients disability, mechanisms such as cognitive deficits [8,10], abnormal ipsilateral descending output and spinal reflexes [10-12, 15, 18] have not been discussed. On the contrary, reduced motility and proprioceptive impairments are themes of discussion which involve both groups of patients.…”

“…It may be caused by cognitive deficits affecting perception and control of action. In patients with left hemisphere damage, ipsilateral motor dysfunction may be due to ideomotor apraxia, while in patients with right hemisphere injury, it may be caused by visuospatial impairments [8,10]. However, impaired ipsilateral function has also been reported in patients without cognitive impairment [2,3].…”

Motor dysfunction of the “non-affected” lower limb: a kinematic comparative study between hemiparetic stroke and total knee prosthesized patients

In patients with hemispheric stroke, abnormal motor performances are described also in the ipsilateral limbs. They may be due to a cortical reorganization in the unaffected hemisphere; moreover, also peripheral mechanisms may play a role. To explore this hypothesis, we studied motor performances in 15 patients with hemispheric stroke and in 14 patients with total knee arthroplasty, which have a reduced motility in the prosthesized leg. Using the unaffected leg, they performed five superimposed circular trajectories in a prefixed pathway on a computerized footboard, while looking at a marker on the computer screen. The average trace error was significantly different between the groups of patients and healthy subjects [F (2,25) = 7.9; p = 0.003]; on the contrary, the test time execution did not vary significantly. In conclusion, both groups of patients showed abnormal motor performances of the unaffected leg; this result suggests a likely contribution of peripheral mechanisms.

“…However, deficits in the ipsilesional hemisphere, considered "healthy", or "less affected", are also observed (5 -8). For example, following a stroke, people have an inferior performance when using the ipsilesional upper limb in reaching tasks (9,10) or even in clinical tests (7,8,11,12), when compared to those who have not had a stroke.…”

Introduction: Stroke individuals have sensorimotor repercussions on their ipsilesional upper limb. Therefore, it is important to use tests that allow an adequate assessment and follow-up of such deficits. Physical and occupational therapists commonly use maximal grip strength tests to assess the functional condition of stroke individuals. However, one could ask whether a single test is able to characterize the hand function in this population. Objective: The aim of this study was to investigate the relationship among outcomes of different tests frequently used to describe the function of the hand in the ipsilesional upper limb of stroke individuals. Methods: Twenty-two stroke individuals performed four hand function tests: maximal handgrip strength (HGSMax), maximal pinch grip strength (PGSMax), Jebsen-Taylor Hand Function Test (JTHFT) and Nine Hole Peg Test (9-HPT). All tests were performed with the ipsilesional hand. Pearson's correlation analyses were performed. Results: the results indicated a moderate and positive relationship between HGSMax and JTHFT (r = 0.50) and between JTHFT and 9-HPT (r = 0.55). Conclusion: We conclude that the existence of only moderate relationships between test outcomes demonstrates the need to use at least two instruments to better describe the ipsilesional hand function of stroke individuals.

“…Although the contralateral and ipsilateral alterations of the upper limbs of hemiparetic patients have been well documented in the literature [5][6][7][8][9][10] it is important to investigate which dominant (preference) manual influences over the motor, sensory and functional aspects of these patients. The objective of this study was to verify if the functional hemispheric asymmetry play an influence over the deficits of upper limbs of hemiparetic stroke patients, as well as if these possible alterations are different between men and women.…”

Entre homens e mulheres houve diferença apenas na dinamometria manual (lado parético p=0,001 e lado não parético p<0,000). Quanto à dominância hemisférica houve diferença no membro parético, sendo o melhor desempenho no teste de caixa e blocos no lado dominante (p=0,016). Conclusão. Nos hemiparéticos as alterações contralaterais são globais e mais graves, e as ipsilaterais são relacionadas à destreza manual. A avaliação e o planejamento da reabilitação destes pacientes devem contemplar abordagens globais e não apenas restritas aos défi-cits contralaterais.Unitermos.

Déficits nos membros superiores após Acidente Vascular Cerebral: influências das assimetrias funcionais hemisféricas. ABSTRACTObjective. To verify whether the functional hemispheric asymmetries exert influence over the deficits on upper limbs of hemiparetic stroke patients. Method. 42 right-handed patients participated in the study, 18 women and 24 men, average age 61.7±10 years, average time lesion 22±15.1 months. The instruments of measurements: Handgrip Dynamometer, Esthesiometer, Box and Blocks Test, Nine Hole and Peg Test, Barthel Index, Movements Hand Scale and the Modified Ashworth Scale. Results. All tests showed a difference between the paretic and non-paretic sides. Between men and women there was a difference only in the handgrip (p=0.001 paretic side and p<0.000 non paretic side). As hemispheric dominance was different in the paretic limb, with the best performance in Box and Blocks Test on the dominant side (p=0.016). Conclusion: In hemiparetic patients the contralateral alterations are global and more severe, and the ipsilateral are related to the manual dexterity. The evaluation and the rehabilitation planning of these patients have to consider global approaches and not only limited to the contralateral deficits.
