Brief Summary

The goal of this clinical trial was to compare the effect of two different types of stretching techniques in elderly population. The main questions it aims to answer are:

1. 1.What is the immediate effect (after a single intervention) of these stretching techniques on muscle flexibility, amount of knee joint motion and muscle activity?
2. 2.What is the effect of a four week intervention program of these stretching techniques on muscle flexibility, amount of knee joint motion and muscle activity? There were three groups with ten randomly allocated participants in each group. Intervention group I was given a stretching technique called contract-relax technique and the Intervention group II was given static stretching. The third group was not given any treatment and was taken as a control. The main aim was to find out that whether the two techniques are effective or not and which one of the two is better than the other in terms of improvement in the above mentioned parameters.

Conditions

Muscle Tightness; Muscle Weakness

Keywords

Contract Relax; Proprioceptive Neuromuscular Facilitation; Electromyography; Elderly; Flexibility; Range of Motion

Outcome Measures

Primary Outcomes (2)

• Change in Active Knee Range of Motion

  The active extension knee range of motion was measured using a universal goniometer.

  Baseline, After 1st intervention (immediate), 4 weeks after intervention

• Change in Maximum Voluntary Isometric Contraction (MVIC)

  The Electromyographic activity of the biceps femoris muscle was evaluated using the surface electrodes during the maximal isometric contraction.

  Baseline, After 1st intervention (immediate), 4 weeks after intervention

Secondary Outcomes (1)

• Change in Hamstring flexibility

  Baseline, After 1st intervention (immediate), 4 weeks after intervention

Study Arms (3)

PNF- CR Group

EXPERIMENTAL

The participants in the group were given PNF contract- relax stretching using the standard protocol. One trial had two isometric contractions each followed by five seconds muscle stretch and there was a total of four trials. Total of 12 sessions in 4 weeks (3sessions/week).

Other: Proprioceptive Neuromuscular Stretching - Contract Relax stretching (PNF-CR)

Static Stretching Group

EXPERIMENTAL

The participants in the group were given sustained stretching for a period of 80s at a stretch. Total of 12 sessions in 4 weeks (3sessions/week).

Other: Static Stretching (SS)

Control Group

NO INTERVENTION

No intervention was given in this group

Interventions

Proprioceptive Neuromuscular Stretching - Contract Relax stretching (PNF-CR) OTHER

PNF-CR utilized the concept of autogenic inhibition of the muscle for improving the flexibility of the muscle. It includes stretching a muscle after a brief period of activation.

PNF- CR Group

Static Stretching (SS) OTHER

The SS technique utilized the concept of creep for improving the hamstring flexibility. The stretch was maintained for a prolonged period passively by the therapist.

Static Stretching Group
