“…(Salik Sengul et al, 2021) Trunk training employing unstable surfaces, for example, therapy ball, increases trunk muscle activity and may remedy side‐to‐side asymmetries (Van Criekinge et al, 2019); side‐to‐side asymmetries have been previously reported post‐LLA. (Sions et al, 2021) Visual biofeedback using ultrasound imaging may enhance lumbar multifidi activity (Cha et al, 2016) and be more effective than tactile and/or verbal cueing alone, particularly for retaining gains in muscle activity between treatment sessions. (Van Criekinge et al, 2019) Of note, however, multifidi activity elicited with single limb lifts, while safe in terms of imparted spinal loading, may not produce sufficient muscle activity to evoke desired extensor muscle strength gains (i.e., >50% of a maximal volitional contraction).…”

Trunk muscles may be an overlooked region of deficits following lower‐limb amputation (LLA). This study sought to determine the extent that trunk muscle deficits are associated with physical function following amputation. Sedentary adults with a unilateral transtibial‐ (n = 25) or transfemoral‐level (n = 14) amputation were recruited for this cross‐sectional research study. Participants underwent a clinical examination that included ultrasound imaging of the lumbar multifidi muscles, the modified Biering‐Sorensen Endurance Test (mBSET), and performance‐based measures, that is, the Timed Up and Go (TUG), Berg Balance Scale (BBS), and 10‐m Walk Test (10mWT). Associations between trunk muscle metrics and performance were explored with regression modeling, while considering covariates known to impact performance postamputation (p ≤ 0.100). Average ultrasound‐obtained, lumbar multifidi activity was 14% and 16% for transfemoral‐ and transtibial‐level amputations, respectively, while extensor endurance was 37.34 and 12.61 s, respectively. For TUG, nonamputated‐side multifidi activity and an interaction term (level x non‐amputated‐side multifidi activity) explained 9.4% and 6.2% of the total variance, respectively. For 10mWT, beyond covariates, non‐amputated‐side multifidi activity and the interaction term explained 6.1% and 5.8% of the total variance, respectively. For TUG, extensor endurance and an interaction term (level x mBSET) explained 11.9% and 8.3% of the total variance beyond covariates; for BBS and 10mWT, extensor endurance explained 11.2% and 17.2% of the total variance, respectively. Findings highlight deficits in lumbar multifidi activity and extensor muscle endurance among sedentary adults with a LLA; reduced muscle activity and endurance may be important factors to target during rehabilitation to enhance mobility‐related outcomes.

BACKGROUND: The abdominal drawing-in exercise could help improve delayed transversus abdominis (TrA) activation during limb movement in subjects with recurrent low back pain (rLBP). However, little is known about whether the same effect is observed during lifting tasks in subjects with rLBP. OBJECTIVE: This study aimed to clarify whether a single session of abdominal drawing-in exercise could correct the altered trunk muscle activation patterns during a lifting task in subjects with rLBP. METHODS: Fifteen subjects with rLBP performed lifting tasks before and immediately after three sets of 10 repetitions of isolated TrA voluntary contractions. The time of onset and activation amplitude during the lifting tasks were measured by surface electromyography (EMG) and compared between the trials before and immediately after exercise. RESULTS: During lifting, the onset of internal abdominal oblique/TrA (IO/TrA) and multifidus activation occurred earlier, the EMG amplitude of IO/TrA increased, and the EMG amplitude of erector spinae and multifidus decreased, compared with the pre-exercise data. CONCLUSIONS: These results suggest a possibility that the abdominal drawing-in exercise might be effective in improving the muscle recruitment pattern in people with rLBP.
