Objective: To examine the effects of whole-body vibration on neuromuscular performance in people with spinal cord injury and evaluate the safe and effective vibration protocols. Methods: PubMed, EMBASE, CINAHL and PEDro were mainly searched for English literatures. Other data sources were ClinicalTrials.gov , Current Controlled Trials and reference lists of all relevant articles. The PEDro scale was used to evaluate the methodological quality, and the Oxford Centre for Evidence-based Medicine level of evidence was used to assess the level of evidence. Basic information and whole-body vibration protocols were extracted by two independent researchers. Any disagreements were resolved by the third researcher. Results: Of the eight included studies involving 94 individuals with spinal cord injury and 24 able-bodied participants, six of them reported beneficial effects of whole-body vibration on muscle activation and the other two on muscle spasticity. Based on the reviewed studies, an intermittent mode of whole-body vibration (frequency: 10–50 Hz; amplitude: 0.6–4 mm) is less likely to cause adverse events when applying to spinal cord injury subjects standing on platform (knees flexed at 10°–40°). Conclusions: The strength of evidence is insufficient in supporting the benefits of whole-body vibration on neuromuscular performance in individuals with spinal cord injury. The intermittent vibration (frequency: 10–50 Hz; amplitude: 0.6–4 mm; knee flexion: 10°–40°) may be the possible effective range and have good compliance.

Limb Dominance

The purpose of this study was to investigate the effects of how limb dominance and joint immobilization alter markers of physical demand and muscle activation during ambulation with axillary crutches. In a crossover, counterbalanced study design, physically active females completed ambulation trials with three conditions: (1) bipedal walking (BW), (2) axillary crutch ambulation with their dominant limb (DOM), and (3) axillary crutch ambulation with their nondominant limb (NDOM). During the axillary crutch ambulation conditions, the non-weight-bearing knee joint was immobilized at a 30-degree flexion angle with a postoperative knee stabilizer. For each trial/condition, participants ambulated at 0.6, 0.8, and 1.0 mph for five minutes at each speed. Heart rate (HR) and rate of perceived exertion (RPE) were monitored throughout. Surface electromyography (sEMG) was used to record muscle activation of the medial gastrocnemius (MG), soleus (SOL), and tibialis anterior (TA) unilaterally on the weight-bearing limb. Biceps brachii (BB) and triceps brachii (TB) sEMG were measured bilaterally. sEMG signals for each immobilization condition were normalized to corresponding values for BW.HR (p < 0.001) and RPE (p < 0.001) were significantly higher for both the DOM and NDOM conditions compared to BW but no differences existed between the DOM and NDOM conditions (p > 0.05). No differences in lower limb muscle activation were noted for any muscles between the DOM and NDOM conditions (p > 0.05). Regardless of condition, BB activation ipsilateral to the ambulating limb was significantly lower during 0.6 mph (p = 0.005) and 0.8 mph (p = 0.016) compared to the same speeds for BB on the contralateral side. Contralateral TB activation was significantly higher during 0.6 mph compared to 0.8 mph (p = 0.009) and 1.0 mph (p = 0.029) irrespective of condition. In conclusion, limb dominance appears to not alter lower limb muscle activation and walking intensity while using axillary crutches. However, upper limb muscle activation was asymmetrical during axillary crutch use and largely dependent on speed. These results suggest that functional asymmetry may exist in upper limbs but not lower limbs during assistive device supported ambulation.
