The utility of upper limb loading device in determining optimal walking ability in ambulatory individuals with spinal cord injury.

BACKGROUND: Walking devices are frequently prescribed for many individuals, including those with spinal cord injury (SCI), to promote their independence. However, without proper screening and follow-up care, the individuals may continue using the same device when their conditions have progressed, that may possibly worsen their walking ability. OBJECTIVE: This study developed an upper limb loading device (ULLD), and assessed the possibility of using the tool to determine the optimal walking ability of ambulatory participants with SCI who used a walking device daily ( n = 49 ). METHODS: All participants were assessed for their optimal walking ability, i.e., the ability of walking with the least support device or no device as they could do safely and confidently. The participants were also assessed for their amount of weight-bearing on the upper limbs or upper limb loading while walking, amount of weight-bearing on the lower limbs or lower limb loading while stepping of the other leg, and walking performance. RESULTS: The findings indicated that approximately one third of the participants (31%) could progress their walking ability from their current ability, whereby four participants could even walk without a walking device. The amount of upper limb loading while walking, lower limb loading ability, and walking performance were significantly different among the groups of optimal walking ability ( p < 0 . 05 ). Furthermore, the amount of upper limb loading showed negative correlation to the amount of lower limb loading and walking performance ( ρ =- 0 . 351 to - 0.493, p < 0 . 05 ). CONCLUSION: The findings suggest the potential benefit of using the upper limb loading device and the amount of upper limb loading for walking device prescription, and monitoring the change of walking ability among ambulatory individuals with SCI.

External Devices Among Individuals With Spinal Cord Injury From a Developing Country.

OBJECTIVE: The aim of this study was to explore the proportion, number, and type of external devices (including mobility devices, ambulatory aides, and orthotics) possessed and used by individuals with spinal cord injury (SCI) from a developing country. DESIGN: This was a cross-sectional study. PARTICIPANTS: A total of 163 participants with SCI from several rural communities in a developing country participated in the study from June 2018 to August 2019. METHODS: The participants were interviewed and assessed for their SCI characteristics and the external devices (i.e., mobility devices, ambulatory aides, and orthotics) they possessed and used in their daily living. RESULTS: Most participants (85%), who lived in rural communities with a family income of less than $3167 per year, possessed external devices (one to five types), and 80% of all participants actually used the devices (one to three types) in their daily living. Most participants with motor-complete SCI used a single device, especially a manual wheelchair, whereas those with mild lesion severity used multiple devices for their daily activities, particularly a standard walker. CONCLUSION: Owing to budget and environmental constraints, the external devices used by individuals with SCI from a developing country are different from those reported in a developed country. The findings provide particular insights into the management of external devices for these individuals of a developing country.

Is walking symmetry important for ambulatory patients with spinal cord injury?

PURPOSE: To assess and compare the levels of walking symmetry in ambulatory participants with spinal cord injury (SCI) who had different degrees of lesion severity, levels of walking ability, and fall history. In addition, the study explored the relationship between the levels of walking symmetry and variables related to the ability of well-controlled walking of the participants. STUDY DESIGN: Cross-sectional study. METHODS: Sixty-six eligible participants were assessed and interviewed for levels of walking symmetry, walking speed, functional endurance, symmetrical lower limb support ability, balance control, and fall history over the last 6 months. RESULTS: Participants walked asymmetrically (85%) similar to those with unilateral impairments (i.e., patients with stroke and amputee, 79-93%). The levels of walking symmetry were significantly correlated to walking speed, functional endurance and balance ability of the participants (p < 0.05). The problem and correlation were particularly apparent in those with the history of multiple falls (79%, r = 0.613-0.765, p < 0.005) Conclusions: The findings confirm problems of asymmetrical walking and the importance of walking symmetry for the ability of well-controlled walking and a risk of multiple falls in ambulatory participants with SCI. Therefore, apart from the levels of independence, the improvement of walking symmetry is crucial for these individuals. Implications for Rehabilitation: Ambulatory individuals with spinal cord injury walked asymmetrically at the same level as those with unilateral impairments such as patients with stroke and amputee. Their levels of walking symmetry were significantly related to the ability of well-controlled walking, particularly in those with the history of multiple falls. The finding confirmed the importance of walking symmetry as a crucial parameter to detect walking improvement and fall risk reduction. Apart from the levels of independence, rehabilitation professionals also need to emphasize on the improvement of symmetrical walking for these patients.
