Vertical Lift

A walker capable of providing vertical lift support can improve independence and increase mobility of individuals living with spinal cord injury (SCI). Using a novel lifting mechanism, a walker has been designed to provide sit-to-stand assistance to individuals with partially paralyzed lower extremity muscles. The design was verified through experiments with one individual with SCI. The results show the walker is capable of reducing the force demands on the upper and lower extremity muscles during sit-to-stand transition compared to standard walkers. The walker does not require electrical power and no grip force or harness is necessary during sit-to-stand operation, enabling its use by individuals with limited hand function. The design concept can be extended to aid other populations with lower extremity weakness.

Therapeutic Exercises

Electromyography (EMG) sensors have been used to study the sequence of muscle contractions during sit-to-stand (STS) in post-stroke patients. However, the majority of the studies used wired sensors with a limited number of placements. Using the latest improved wearable technology with 16 sensors, the current study was a thorough investigation to evaluate the contraction sequences of eight key muscles on the trunk and bilateral limbs during STS in post-stroke patients, as it became feasible. Multiple wearable sensors for the detection of muscle contraction sequences showed that the post-stroke patients performed STS with abnormal firing sequences, not only in the primary mover on the sagittal plane during raising, but also in the tibialis anterior, which may affect anticipatory postural adjustment in the gluteus medius, which may affect balance control. The abnormal tibialis anterior contraction until the early ascending phase and the delayed firing of the gluteus muscles highlight the importance of whole-kinetic-chain monitoring of contraction sequences using wearable sensors. The findings can be helpful for the design of therapeutic exercises.

Objective: Submissions on recovery of post-stroke motor performance vary, especially in relation to increasing time after stroke. This study examined the trajectory of motor performance over the first 12 months after stroke.Methods: Consecutive first-incidence stroke survivors (N = 83) were recruited within 1 month of onset from a tertiary health institution in Nigeria. Simplified Fugl Meyer scale (S-FM) was used to assess motor performance at monthly intervals. Changes in overall motor performance, and differences between the affected upper and lower extremities, were examined using Friedman's ANOVA and paired t-tests, respectively.Results: Significant improvement in motor performance was observed across 12 months (p < .001), with the proportion of stroke survivors with severe impairment at onset (53.3%) decreasing to 20% by 12 months. Lower extremity motor performance scores were significantly higher than for the upper extremity from 1 to 12 months (p <.01 at 3, 4, 5, 6 and 12 months; and p < .05 at the remaining months).Conclusions: The potential for long-term improvement in motor performance after stroke was observed, suggesting that this can be harnessed by long-term rehabilitation efforts. The comparatively poorer outcome in the upper extremity indicates the need for extra rehabilitation strategies to enhance upper-extremity motor recovery in the first year of stroke.
