Low Intensity Pulsed Ultrasound (LIPUS) is beneficial in accelerating fracture recovery, enhancing their capacity to execute tasks of daily life and, as a result, their autonomy.
To compare the outcomes of routine physical therapy and routine physical therapy along with LIPUS in patients with early-stage lumbar spondylolysis.
Thirty-four (29 males and 5 females) patients exhibiting symptomatic low back pain for at least four weeks were recruited and randomly divided into control group (CG) and intervention group (IG) group. Randomization was done by using goldfish bowl method and allocation was done by using sealed envelope method. Parallel assignment was done. Numeric Pain Rating Scale (NPRS) was utilized for the measurement of pain and Oswestry Disability Index (ODI) for functional disability. Patients were assessed at baseline, at the end of 12th and 20th week. Interventions were applied by two physical therapists (one male and one female) having more than eight years of clinical experience for 10 weeks on alternate days.
Intervention group reported significant percentage change of 47% at 12th week and 65% at 20th week for pain and 42% at 12th week and 81% at 20th week for functional disability compared with 40% at 12th week and 37% at 20th week for pain and 3% at 12th week and 25% at 20th week follow-up for functional disability from baseline in control group.
Low-intensity pulsed ultrasound has significantly reduced pain and functional disability in patients with early-stage lumbar spondylolysis by using following parameters; 1.1-MHz oscillation frequency, 1-kHz pulsed frequency, 100-mW/cm spatial intensity, 2 ms pulse duration, 100Hz pulse repetition rate, 20% pulse duty cycle, and 20-min duration on alternate days.
低强度脉冲超声（LIPUS）有助于加速骨折愈合，提高其执行日常生活任务的能力，从而提高其自主性。
比较常规物理治疗与常规物理治疗联合 LIPUS 治疗早期腰椎峡部裂患者的疗效。
共纳入 34 例（29 名男性，5 名女性）有腰痛症状至少 4 周的患者，并随机分为对照组（CG）和干预组（IG）。采用金鱼缸法进行随机分组，采用密封信封法进行分组。采用平行分组。采用数字疼痛评分量表（NPRS）测量疼痛，采用 Oswestry 功能障碍指数（ODI）测量功能障碍。患者在基线、第 12 周和第 20 周时进行评估。干预措施由两位具有 8 年以上临床经验的物理治疗师（一位男性，一位女性）在第 10 周内隔日进行 10 次。
干预组疼痛的百分比变化在第 12 周和第 20 周时分别为 47%和 65%，功能障碍的百分比变化在第 12 周和第 20 周时分别为 42%和 81%，而对照组疼痛的百分比变化在第 12 周和第 20 周时分别为 40%和 37%，功能障碍的百分比变化在第 12 周和第 20 周时分别为 3%和 25%。
采用 1.1MHz 振荡频率、1kHz 脉冲频率、100mW/cm2 空间强度、2ms 脉冲持续时间、100Hz 脉冲重复率、20%脉冲占空比和隔日 20min 的参数，低强度脉冲超声可显著减轻早期腰椎峡部裂患者的疼痛和功能障碍。
