简要总结
This randomized clinical trial aims to compare the effects of post-isometric relaxation (PIR) and post-facilitation stretch (PFS) on pain, range of motion, and disability in individuals with tight hamstring syndrome. Conducted at Riphah Rehabilitation Clinic, Lahore, participants aged 18-35 years with posterior thigh pain will be divided into two groups. Both groups will receive hot pack therapy and core strengthening exercises, with Group A receiving PIR and Group B receiving PFS. Outcomes will be assessed at baseline and after 4 weeks using NPRS, a disability questionnaire, and a goniometer, with data analyzed using SPSS version 25.
详细描述
Both PIR and PFS are subtypes of Muscle Energy Techniques (MET) that have shown potential in improving muscle flexibility and reducing discomfort. This study aims to address the impacts of PIR and PFS on pain, ROM, and disability in patients with tight hamstrings syndrome, providing valuable insights for clinical practice and enhancing the understanding of effective interventions for this common musculoskeletal issue.
The current literature on stretching techniques for musculoskeletal conditions reveals several gaps specifically relevant to the effects of Post Isometric Relaxation (PIR) and Post Facilitation Stretch (PFS) on tight hamstrings syndrome. Despite the high incidence of hamstring tightness and its association with conditions such as nonspecific low back pain, there is limited research directly comparing the effects of Post Isometric Relaxation (PIR) and Post Facilitation Stretch (PFS) on this condition. While studies have explored various stretching methods such as Muscle Energy Technique (MET), static stretching, and myofascial release, there is a notable lack of direct comparative research between PIR and PFS in patients with tight hamstrings. Additionally, existing studies had often focused on immediate or short-term outcomes, with limited investigation into the long-term effects of these techniques on pain, range of motion (ROM), and disability.

研究组 & 干预措施
Post Isometric Relaxation
Patient applied the sub-maximal contraction almost 20%. Isometric contraction will be held for 10 seconds and then slight stretch for 30 seconds will be maintained. 4 contractions per treatment with 3 seconds rest between each contraction. This protocol continues 3 days/week for 4 weeks
干预措施: Post Isometric relaxation (Other)
Post Facilitation Stretch
Isometric contraction will be held for 10 seconds and then slight stretch for 30 seconds will be maintained. 4 contractions per treatment with 3 seconds rest between each contraction. This protocol continues 3 days/week 4 weeks. for hamstring flexibility
干预措施: Post Facilitation stretch (Other)
结局指标
主要结局
Numeric pain rating scale
时间窗: 4th week
The severity of pain will be measured by using the NPRS scale, which goes from '0' (meaning there is no pain) to 10'' (meaning there is most agony possible) ("pain is severe as you can imagine"). It was accepted that the scale was convenient for determining patients' pain thresholds. The NPRS scale has a score range of 0 to 10. It was a valid and reliable tool. Va;idity ranging from 0.79 to 0.95 and reliability from 0.67 to 0.96.
次要结局
- Active Knee Extension Test(4th week)
- Modified Oswestry Disability Index(4th week)
